PREFACE.
A puzzle is not solved, impatient sirs,
By peeping at its answer in a trice:
When Gordius, the ploughboy King of Phrygia,
Tied up his implements of husbandry
In the far-famed knot, rash Alexander
Did not undo by cutting it in twain.
It is hoped that this little book may prove useful, not only in connection
with puzzles for home amusement, but that by inducing people to consider
the various difficulties met with in business and trade some at least may be
led to greater success in dealing with the practical puzzles and problems of
everyday life.
It is the special desire of the author to produce a “sugar-coated
mathematical pill,” as he feels convinced that many can more easily grasp
the truth when it is put before them in a light manner than when brought
forward in the usual orthodox fashion.
No pains have been spared to make the Puzzle King the best of its kind
yet produced, and the author here wishes to thank his many friends who
have so kindly assisted him. It would be well-nigh impossible to
individualize; but especial thanks are due to Thos. Finney, Esq., M.L.A.
(Brisbane), for the interest he has manifested throughout, and the kindly
help he has so often rendered the author.
It might afford our readers some pleasure to know that this work is
entirely Australian. The printers, artist, and author are all colonial-born, and
the production of the former two, at any rate, will compare favourably with
that of any others.
The engravings throughout have been in the hands of Mr. Murray Fraser
and staff, whose experience in this special art has tended to make the book
more attractive than it otherwise would have been.

READING BIG NUMBERS.
Wonderful Calculations.
Although we are accustomed to speak in the most airy fashion of
millions, billions, &c., and “rattle” off at a breath strings of figures, the fact
still remains that we are unable to grasp their vastness. Man is finite—
numbers are infinite!
ONE MILLION
Is beyond our conception. We can no more realise its immensity, than we
can the tenth part of a second. It should be a pleasing fact to note that
commercial calculations do not often extend beyond millions; generally
speaking, it is in the realm of speculative calculation only, such as
probability, astronomy, &c., that we are brought face to face with these
unthinkable magnitudes.
Who, for instance, could form the slightest idea that the odds against a
person tossing a coin in the air so as to bring a head 200 times in succession
are
160693804425899027554196209234116260522202993782792835301375
(over I decillion, &c.) to 1 against him? Suppose that all the men, women
and children on the face of the earth were to keep on tossing coins at the
rate of a million a second for a million years, the odds would still be too
great for us to realise against any one person succeeding in performing the
above feat, and yet the number representing the odds would be only half as
long as the one already given.
Or, who could understand the other equally astounding fact that Sirius,
the Dog-star, is 130435000000000 miles from the earth, or even that the

WHAT IS A BILLION
In Europe and America, the billion is 1,000,000,000—a thousand
millions—but in Great Britain and her Colonies, a billion is reckoned
1,000,000,000,000—a million millions: a difference which should perhaps
be worth remembering in the case of francs and dollars.
One billion sovereigns placed side by side would extend to a distance of
over 18,000,000 miles, and make a band which would pass 736 times round
the globe, or, if lying side by side, would form a golden belt around it over
26 ft. wide; if the sovereigns were placed on top of each other flatways, the
golden column would be more than a million miles in height.
Supposing you could count at the rate of 200 a minute; then, in one
hour, you could count 12,000—if you were not interrupted. Well, 12,000 an
hour would be 288,000 a day; and a year, or 365 days, would produce
105,120,000. But this would not allow you a single moment for sleep, or for
any other business whatever. If Adam at the beginning of his existence, had
begun to count, had continued to count, and were counting still, he would
not even now, according to the usually supposed age of man, have counted
nearly enough. To count a billion, he would require 9,512 years, 342 days, 5
hours and 20 minutes, according to the above reckoning. But suppose we
were to allow the poor counter twelve hours daily for rest, eating and
sleeping, he would need 19,025 years, 319 days, 10 hours and 40 minutes to
count one billion.
A comparison—
One million seconds = less than 12 days
" billion " = over 31,000 years
A GOOD CATCH.
1.—Ask a person to write, in figures, eleven thousand, eleven hundred
and eleven. This often proves very amusing, few being able to write it
correctly at first.

Naturalists state that snakes, when in danger, have been known to
swallow each other; the above three snakes have just commenced to
Page 13
perform this operation. The snakes are from the same “hatch,” and are
therefore equal in age, length, weight, &c. They all start at scratch—that is,
commence swallowing simultaneously. They are twirling round at the
express rate of 300 revolutions per minute, during which time the
circumference is decreased by 1 inch.

A GOOD CARD TRICK.
The performer lays upon the
table ten cards, side by side, face
downwards. Anyone is then at
liberty (the performer meanwhile
retiring from the room) to shift any
number of the cards (from one to
nine inclusive) from the right hand
end of the row to the left, but
retaining the order of the cards so
shifted. The performer, on his
return, makes a little speech:
“Ladies and gentlemen, you have
shifted a certain number of these
cards. Now, I don’t intend to ask
you a single question. By a simple
mental calculation I can ascertain the number you have moved, and by my
clairvoyant faculty, though the cards are face downwards, I shall pick out
one corresponding with that number. Let me see” (pretends to calculate, and
presently turns up a card representing “five”). “You shifted five cards and I
have turned up a five, the exact number.”

presently turns up a card representing “five”). “You shifted five cards and I
have turned up a five, the exact number.”
Page 14
The cards moved are not replaced, but the performer again retires, and a
second person is invited to move a few more from right to left. Again the
performer on his return takes up the correct card indicating the number
shifted. The trick, unlike most others, may be repeated without fear of
detection.
The principle is arithmetical. To begin with, the cards are arranged,
unknown to the spectators, in the following order:
Ten, nine, eight, seven, six, five, four, three, two, one.
Such being the case, it will be found that, however many are shifted
from right to left, the first card of the new row will indicate their number.
Thus, suppose three are shifted. The new order of the cards will then be:
Three, two, one, ten, nine, eight, seven, six, five, four.
So far, the trick is easy enough, but the method of its continuance is a
trifle more complicated. To tell the position of the indicating card after the
second removal, the performer privately adds the number of that last turned
up (in this case three) to its place in the row—one. That gives us four, the
card to be turned up after the next shift will be the fourth. Thus, suppose six
cards are now shifted, their new order will be:
Nine, eight, seven, six, five, four, three, two, one, ten.
Had five cards only been shifted, the five would have been fourth in the
row, and so on.
The performer now adds six, the number of the card, to its place in the
row, four: the total, ten, gives him the position of the indicator for the next
attempt. Thus, suppose four cards are next shifted, the new order will be:
Three, two, one, ten, nine, eight, seven, six, five, four.
The next calculation, 4 and 10, gives us a total 14. The ten is, in this
case, cancelled, and the fourteen regarded as four, which will be found to be
the correct indicator for the next shifting.
It looks more mystifying if the performer be blindfolded, for he can tell
the position of the cards with his fingers. Keeping his hand on the card, he
asks, “Will you please tell me how many cards were shifted?” As soon as
second person is invited to move a few more from right to left. Again the
performer on his return takes up the correct card indicating the number
shifted. The trick, unlike most others, may be repeated without fear of
detection.
The principle is arithmetical. To begin with, the cards are arranged,
unknown to the spectators, in the following order:
Ten, nine, eight, seven, six, five, four, three, two, one.
Such being the case, it will be found that, however many are shifted
from right to left, the first card of the new row will indicate their number.
Thus, suppose three are shifted. The new order of the cards will then be:
Three, two, one, ten, nine, eight, seven, six, five, four.
So far, the trick is easy enough, but the method of its continuance is a
trifle more complicated. To tell the position of the indicating card after the
second removal, the performer privately adds the number of that last turned
up (in this case three) to its place in the row—one. That gives us four, the
card to be turned up after the next shift will be the fourth. Thus, suppose six
cards are now shifted, their new order will be:
Nine, eight, seven, six, five, four, three, two, one, ten.
Had five cards only been shifted, the five would have been fourth in the
row, and so on.
The performer now adds six, the number of the card, to its place in the
row, four: the total, ten, gives him the position of the indicator for the next
attempt. Thus, suppose four cards are next shifted, the new order will be:
Three, two, one, ten, nine, eight, seven, six, five, four.
The next calculation, 4 and 10, gives us a total 14. The ten is, in this
case, cancelled, and the fourteen regarded as four, which will be found to be
the correct indicator for the next shifting.
It looks more mystifying if the performer be blindfolded, for he can tell
the position of the cards with his fingers. Keeping his hand on the card, he
asks, “Will you please tell me how many cards were shifted?” As soon as
Page 15
the answer is given, he exhibits the card, and can continue the trick as long
as he pleases.

SOME CURIOUS NUMBERS.
If the number 37 be multiplied by 3, or any multiple of 3 up to 27, the
product is expressed by three similar digits. Thus—
37 × 3 = 111
37 × 6 = 222
37 × 9 = 333
The products succeed each other in the order of the digits read
downwards, 1, 2, 3, etc., these being multiplied by 3 (their number of
places) reproduce the multiplicand of 37.
1×3=3
2×3=6
3×3=9
If it be multiplied by multiples of 3, beyond 27, this peculiarity is
continued, except that the extreme figures taken together represent the
multiple of 3 that is used as a multiplier. Thus—
37 × 30 = 1110, extreme figures, 10
37 × 33 = 1221 " " 11
37 × 36 = 1332 " " 12
The number 73 (which is 37 inverted) multiplied by each of the
numbers of arithmetical progression 3, 6, 9, 12, 15, etc., produces products
terminating (unit’s place) by one of the ten different figures, 1, 2, 3, 4, 5, 6,
7, 8, 9, 0. These figures will be found in the reverse order to that of the
progression, 73 × 3 produces 9, by 6 produces 8, and 9 produces 7, and so
on.
Another number which falls under some mysterious law of series is
142,857, which, multiplied by 1, 2, 3, 4, 5, or 6 gives the same figures in
the same order, beginning differently; but if multiplied by 7, gives all 9’s.
If the number 37 be multiplied by 3, or any multiple of 3 up to 27, the
product is expressed by three similar digits. Thus—
37 × 3 = 111
37 × 6 = 222
37 × 9 = 333
The products succeed each other in the order of the digits read
downwards, 1, 2, 3, etc., these being multiplied by 3 (their number of
places) reproduce the multiplicand of 37.
1×3=3
2×3=6
3×3=9
If it be multiplied by multiples of 3, beyond 27, this peculiarity is
continued, except that the extreme figures taken together represent the
multiple of 3 that is used as a multiplier. Thus—
37 × 30 = 1110, extreme figures, 10
37 × 33 = 1221 " " 11
37 × 36 = 1332 " " 12
The number 73 (which is 37 inverted) multiplied by each of the
numbers of arithmetical progression 3, 6, 9, 12, 15, etc., produces products
terminating (unit’s place) by one of the ten different figures, 1, 2, 3, 4, 5, 6,
7, 8, 9, 0. These figures will be found in the reverse order to that of the
progression, 73 × 3 produces 9, by 6 produces 8, and 9 produces 7, and so
on.
Another number which falls under some mysterious law of series is
142,857, which, multiplied by 1, 2, 3, 4, 5, or 6 gives the same figures in
the same order, beginning differently; but if multiplied by 7, gives all 9’s.

Do Figures Lie?
“Figures cannot lie,” is a very old saying. Nevertheless, we can all be
deceived by them. Perhaps one of the best instances of them leading us
astray is the following:—
An employer engaged two young men, A and B, and agreed to pay them
wages at the rate of £100 per annum. A enquires if there is to be a “rise,”
and is answered by the employer, “Yes, I will increase your wages £5 every
six months.” “Oh! that is very small; it’s only £10 per year,” replied A.
“Well,” said the employer, “I will double it, and give you a rise of £20 per
year.” A accepts the situation on those terms.
B, in making his choice, prefers the £5 every six months. At the first
glance, it would appear that A’s position was the better.
Now, let us see how much each receives up to the end of four years:—

A spieler at a Country Show amused the people with the following
game:—He had 6 large dice, each of which was marked only on one face—
the first with 1, the second 2, and so on to the sixth, which was marked 6.
He held in his hand a bundle of notes, and offered to stake £100 to £1 if, in
throwing these six dice, the six marked faces should come up only once,
and the person attempting it to have 20 throws.
Though the proposal of the spieler does not on the first view appear
very disadvantageous to those who wagered with him, it is certain there
were a great many chances against them.
The six dice can come up 46,656 different ways, only one of which
would give the marked faces; the odds, therefore, in doing this in one throw
would be 46,655 to 1 against, but, as the player was allowed 20 throws, the
probability of his succeeding would be—

The first Arithmetic in English was written by Tonstal, Bishop of
London, and printed by Pinson in 1552.
Two persons playing dominoes 10 hours a day and making 4 moves a
minute could continue 118,000 years without exhausting all the
combinations of the game.
A schoolmaster wrote the word “dozen” on the blackboard, and asked
the pupils to each write a sentence containing the word. He was somewhat
taken aback to find on one of the slates the following unique sentence: “I
dozen know my lesson.”
9. I have a piece of ground, which is neither square
nor round,
But an octagon, and this I have laid out
In a novel way, though plain in appearance, and
retain
Three posts in each compartment; but I doubt
Whether you discover how I apportioned it, e’en
tho’
I inform you ’tis divided into four.
But, if you solve it right, ’twill afford you much
delight
And repay you for the trouble, I am sure.

Also, if these answers be multiplied by any number whatever, a similar
result will be produced.
Example: 135 x 8 = 1080 = 9
If any row of two or more figures be reversed and subtracted from itself,
the figures composing the remainder will, when added, be a multiple of 9,

Tell a person to write a row of figures, then to add them together, and to
subtract the total from the row first written, then to cross out any one of the
figures in the answer, and to add the remaining figures in the answer
together, omitting the figure crossed out; if the total be now told, it is easy
to discover the figure crossed out.
Example: 4367256 = 33
33
4367223 = 27
It should be observed that the figures of the answer to the subtraction
when added together equal 27—a multiple of 9; this, of course, is always
the case. Now, suppose that 7 was the figure crossed out, then the sum of
the figures in the answer (omitting 7) would be 20; this number being told
by the person, it is easily seen that 7 must have been crossed out, as that
figure is required to complete the multiple 27. If after the figure has been
crossed out, the remaining figures total a multiple of 9, it is evident that

Multiply the digits—omitting 8—by any multiple of 9, and the product
will consist of that multiple,

If a figure with a number of ciphers attached to it be divided by 9, the
quotient will be composed of that figure only repeated as many times as
there are ciphers in the dividend; with the same figure as the remainder.

EXCUSES.
Tell a person to write a row of figures, then to add them together, and to
subtract the total from the row first written, then to cross out any one of the
figures in the answer, and to add the remaining figures in the answer
together, omitting the figure crossed out; if the total be now told, it is easy
to discover the figure crossed out.
Example: 4367256 = 33
33
4367223 = 27
It should be observed that the figures of the answer to the subtraction
when added together equal 27—a multiple of 9; this, of course, is always
the case. Now, suppose that 7 was the figure crossed out, then the sum of
the figures in the answer (omitting 7) would be 20; this number being told
by the person, it is easily seen that 7 must have been crossed out, as that
figure is required to complete the multiple 27. If after the figure has been
crossed out, the remaining figures total a multiple of 9, it is evident that
either a cipher or a 9 must have been the figure erased.
Multiply the digits—omitting 8—by any multiple of 9, and the product

THE PUZZLE ABOUT THE “PER CENTS.”
There are many persons engaged in business who often become badly
mixed when they attempt to handle the subject of per centages. The
ascending scale is easy enough: 5 added to 20 is a gain of 25%; given any
sum of figures the doubling of it is an addition of 100%. But the moment
the change is a decreasing calculation the inexperienced mathematician
betrays himself, and even the expert is apt to stumble or go astray. An
advance from 20 to 25 is an increase of 25%; but the reverse of this, that is,
a decline from 25 to 20 is a decrease of only 20%.
There are many persons, otherwise intelligent, who cannot see why the
reduction of 100 to 50 is not a decrease of 100%, if an advance from 50 to
100 is an increase of 100%.
The other day, an article of merchandise which had been purchased at
10 pence a pound was resold at 30 pence a pound—an advance of 200%.
Whereupon, a writer in chronicling the sale said that at the beginning of the
recent depression several invoices of the same class of goods which had
cost over 30 pence per pound had been finally sold at 10 pence per pound—
a loss of over 200%! Of course there cannot be a decrease or loss of more
than 100%, because this wipes out the whole investment and makes the
price nothing. An advance from 10 to 30 is a gain of 200%; but a decline of
30 to 10 is a loss of only 66⅔%.

A very deserving trader was ruined by his miscalculations respecting
mercantile discounts. The article he manufactured he at first supplied to
retail dealers at a large profit of about 30%. He afterwards confined his
trade almost exclusively to large wholesale houses, to whom he charged the
same price, but allowed a discount of 20%, believing that he was still
realising 10% for his own profit. His trade was very extensive, and it was
not till after some years that he discovered the fact that in place of making
10% profit, as he imagined, by this mode of making his sales he was
realising only 4%. To £100 value of goods he added 30%, and invoiced
them at £130. At the end of each month, in the settlement of accounts
amounting to some thousands of pounds with individual houses, he
deducted 20%, or £26 on each £130, leaving £104, value of goods at prime
cost, instead of £110, as he all along expected.

MIND-READING WITH CARDS.
Hand the pack (a full one) to be shuffled by as many spectators as wish;
then propose that someone takes the pack in his hand and secretly chooses a
card, not removing it, but noticing at what number it stands counting from
the bottom; he then returns the pack to you.
Now you have to tell what number the card is from the top. You ask any
one of the spectators to choose any number between 40 and 50, and
whatever number is chosen the card will appear at that number in the pack.
Let us suppose the number chosen is 48.
You then say that it is not necessary for you to even see the cards, which
will give you a good excuse for holding them under the table, or behind
your back. Now subtract the number chosen, 48, from 52, which gives
remainder 4, count off that many cards from the top, and place them at the
bottom. You next say to the gentleman who chooses the card, that “it is now
number 48, according to the general desire, would you please let us know at
what number it originally stood?” Suppose he answers 7. Then, in order to
save time, you commence counting from the top at that number, dealing off
the cards one by one, calling the first card 7, the next 8, and so on. When
you reach 48, it will be the card the gentleman had chosen. It is not

necessary to limit the choice of position to between 40 and 50, but it is
better for two reasons.

stood, also the higher the number chosen, the fewer cards are there to slip

Does the top of a carriage wheel move faster than the bottom? This
question seems absurd. That the top moves faster, however, is perfectly
correct; for if not it would simply move round in the same place: in a wheel
on a fixed axle the bottom moves backward as fast as the top moves
forward; but in a wheel that is going forward, drawn by a progressive axle,
the bottom does not go back at all, but remains almost stationary until it is
its turn to rise and go forward.

A Magic Square is a series of figures arranged in the equal divisions of

They have been called “Magic” because the ancients ascribed to them
great virtues, and because this arrangement of numbers formed the basis
and principle of their talismans. Archimedes devoted a great amount of
men to spare, but on increasing the sides of the square by one man, he

A Magic Square is a series of figures arranged in the equal divisions of

whether horizontally, vertically, or diagonally, form exactly the same sum.
They have been called “Magic” because the ancients ascribed to them
great virtues, and because this arrangement of numbers formed the basis
and principle of their talismans. Archimedes devoted a great amount of
Page 42
attention to them, which has caused
a great many to speak of them as
“the squares of Archimedes.” They
may be either odd or even. When
the former, the following method
will be found valuable:—
With the digits from 1 to 25
form a square so that the numbers
when added up horizontally,
vertically, or diagonally will
amount to 65.
Method.—Imagine an exterior
line of squares above the magic
square you wish to form, and
another on the right hand of it.
These two imaginary lines are shown in the diagram.
1st. In placing the numbers in the square, we must go in the ascending
diagonal direction from left to right, any number which, by pursuing this
direction, would fall into the exterior line must be carried along that line of
squares, whether vertical or horizontal, to the last square. Thus, 1 having
been placed in the centre of the top row, 2 would fall into the exterior
square above the fourth vertical line; then ascending diagonally 3 falls into
the square diagonally from 2, but 4 falls out of it to the end of a horizontal
line, and it must be carried along that line to the extreme left and there
placed. Resuming our diagonal ascension to the right we place 5 where the
reader sees it, and would place 6 in the middle of the top row, but as we find
1 is already there we look for the direction to
2nd. That when in ascending diagonally we come to a square already
occupied, we must place the number which, according to the 1st rule should
go into that occupied square directly under the last number placed: thus, in
ascending with 4, 5, 6, the 6 must be placed under the 5, because the square
next to 5 in diagonal direction is occupied.

HOW TO FIND THE TOTAL OF A ROW OF
FIGURES IN A MAGIC SQUARE.
Rule.—Multiply half the sum of the extremes by the square root of the
greatest extreme.
Referring to the example given above, we see that the extremes 1 and
25 added equal 26—half of which is 13; this multiplied by 5 (the square
root of 25) gives 65 as the total for each row.
Again, in the next question, the two extremes 1 and 81 equal 82, half of
this sum is 41, which multiplied by 9 (the square root of 81) gives 369 as
the total for each row.
42. Arrange the figures from 1 to 81 in a square that when added up
horizontally, vertically, or diagonally the sum will be 369.
HOW THEY WORKED IT.
Mick and Pat, working in the country some distance from a hotel,
arranged with the landlord to take to their hut a small keg of rum. They
were unable to pay for the liquor at the time, having only one threepenny
piece between them; but Mick proposed that every time he had a drink he
would give Pat threepence, and Pat also agreed to pay Mick for his drinks,
the cash thus gathered to be brought to the publican when the keg was
empty. This proposal was accepted by the publican, the keg of rum handed
over to the two Irishmen, who immediately started on their journey. They
had not proceeded very far before their burden made them thirsty. Mick is
the first to pull up with: “Hold on, Pat, I think I’ll have a drink.” “Begorra,”
replied Pat, “you’ll have to pay me for it then.” Mick hands the 3d. to Pat
before having a good “pull.” Pat now being the possessor of the price of a
drink, slakes his thirst by paying Mick 3d. for it. This form of payment is
kept up till the rum has disappeared. On their next visit to the hotel, the 3d
piece is handed to the landlord as being payment, according to terms of
agreement adopted by him.
FIGURES IN A MAGIC SQUARE.
Rule.—Multiply half the sum of the extremes by the square root of the
greatest extreme.
Referring to the example given above, we see that the extremes 1 and
25 added equal 26—half of which is 13; this multiplied by 5 (the square
root of 25) gives 65 as the total for each row.
Again, in the next question, the two extremes 1 and 81 equal 82, half of
this sum is 41, which multiplied by 9 (the square root of 81) gives 369 as
the total for each row.

these bottles to be arranged in a bin in such a

Nothwithstanding this precaution, the servant in
two successive visits stole 8 bottles—4 each
time—re-arranging the bottles each time so that
they still counted 9 on a side. How did he do it?

A “TAKE-DOWN” WITH CARDS.
This is a card trick which depends upon a certain “key,” the possessor of
which will always have the advantage over his uninstructed adversary. It is
played with the first six of each suit—the four aces in one row, next row the
deuces, threes, fours, fives and sixes. The object now will be to turn down
cards alternately, and endeavour to make thirty-one points by so turning
without over-running that number. The chief point is to count so as to end
with the following numbers: 3, 10, 17 or 24.
For instance, we will suppose it your privilege to commence the count;
you would commence with 3, and your adversary would add 6, which
would make 9; it would be then your policy to add 1 and make 10; then, no
matter what number he adds he cannot prevent you making 17, which gives
you the command of the trick. We will suppose he adds 6 and make 16; then
you add 1 and make 17; then he to add 6 and make 23, you add 1 and make
24; then he cannot add any number to make 31, as the highest number he
can add is 6, which would only count 30, so that you can easily add the
remaining 1 and make 31.
If your adversary is not wary, you may safely turn indifferent numbers
at the beginning, trusting to his ignorance to let you count 17 or 24; but, as
his knowledge increases, he will soon learn that 24 is a critical number, and
to play for it accordingly.
If both players know the trick, the first to play must be the winner, as he
is sure to begin with a 3, which commands the game.

TO TELL THE NUMBER THOUGHT OF ON A CLOCK.
Ask a person to think of any number on the
dial of a clock; you then point, promiscuously at
the various numbers, telling the person to add
the number of times you point to the number he
thought of, and when the total reaches 20, you
will be pointing at the number he selected.
For instance, suppose he selected the
number 5. You point indifferently 7 times at the
various numbers, but the 8th time your pointer
must be at XII., his addition will then be 13 (for
5 and 8 added equal 13), the next at XI., his
addition then 14, next at X., and so on. When he calls 20, you will be
pointing at the number he thought of—5.
A very amusing experiment is to ask a person to write down the figures
around the dial of a clock. Nearly all know that the figures are generally the
Roman numerals; but, in writing them down, when they come to the four, it
is very often written IV. instead of IIII.
It is said that a certain king, being unable to find any other fault in a
clock that had been constructed for him, declared that the figure four should
be represented by four strokes (IIII) instead of IV. In vain did the clock-
maker point out the mistake, for his majesty adhered obstinately to his own
opinion, and angrily ordered the alteration to be made. This was done, and
the precedent thus formed has been followed by clockmakers ever since.

53. On Shrove Tuesday last, I’ll tell you what pass’d
In a neighbouring gentleman’s kitchen,
Where pancakes were making, with eggs, and with bacon
As good as e’er cut off a flitchen.
The cook-maid she makes four lusty pancakes
For William her favourite gardener,
“Pray be quick with that four,” cries Jack, “and make
more,
For William won’t let me go partner.”
Being sparing of lard, the pan’s bottom she marr’d
In making the last of Will’s four;
So she said, “Pr’ythee, John, run and borrow a pan,
Or else I can’t make any more.”
Jack soon got a pan, but found by his span
That the first was more wide than the latter,
This being a foot o’er, whereas that before
Was three inches more and a quarter.
Jack cries, “Don’t me cozen, but make half a dozen.
For the pan is much less than before;”
Says Will, “For a crown (and I’ll put the cash down)
Your six will be more than my four.”
“Tis done,” says brisk Jack, and his crown he did stake,
So both of them sent for a gauger;
The dimensions he takes, of all their pancakes,
To determine this important wager.
He found, by his stick, they were equally thick,
So one of Will’s cakes he did take,
Which he straight cut in twain, twelve one-fifth[1] the
chord line;
And gave the less piece unto Jack.
“To the best of my skill,” says the gauger, “this will
Make both of your shares equal and true;”
Will swore that he lied, so, the point to decide,
They refer themselves, sirs, unto you;
Then pray give your answers, as soon as you can, sirs,
For what with their quarrels and jars,
We’re afraid of some murder, for no day goes over
But they fight and are cover’d with scars!

Interesting Items About the Almanac.
The reason why February has only 28 days, while the other months have
30 and 31 is attributable to the vanity of the Emperor Augustus. His uncle
and predecessor corrected the calendar, arranging the year almost as we
have it now; he gave to the year 12 months, or 365¼ days. The months were
—March (the first month), April, May, June, Quintilis, Sextiles, September,
October, November, December, January, and February (the latter being the
last month of the year, which among the Romans had consisted originally of
10 months). Cæsar ordered that the year should begin with January, and
divided the days among them thus: January, March, May, Quintilis,
September, and November each had 31 days; April, June, Sextiles, October
and December had 30 days each; and February (the last month added to the
year) had 29 days regularly and a 30th day every fourth year. After Julius
Cæsar’s death, Mark Antony changed the name of Quintilis to July as we
have it now. Augustus wanted a month for himself, and wanted it as long as
his uncle’s month, so he took Sextiles for his and changed the name to
August. Then he took February’s 29th day and added it to August, so that it
might have 31 days; and, to avoid having 3 months of 31 days each in
succession, September and November were reduced to 30 days, and
October and December increased to 31 days each.
Previous to the year 1752, the legal year in England commenced on the
25th March. In that year it was enacted that the legal year should begin on
1st January. The change brought the calendar into unison with the actual
state of the solar year. It is curious that in Scotland the change which made
the legal year begin on January 1st was effected in 1600. For some time
after the change in England, legal documents contained two dates for the
period intervening between 1st January and 25th March—that of the old
year and that of the new.

During the time of Oliver Cromwell, Christmas Day was described as a
superstitious festival, and put down in England by the strong hand of the
law.
There has been a superstitious notion that Fools’ Day dated back to the
time of Noah’s Ark. The dove that was sent forth from the Ark is supposed
to have returned on April 1st.
The Most Remarkable Month was February, 1866. It had no full moon.
January had two full moons, and so had March, but February had none. This
had not occurred since the creation of the world, and it will not occur again,
so scientists tell us.
All Fools’ Day had it’s origin in France, before the time of the Reformed
Calendar. When the year commenced on March 25th, the French frequently
paid their New Year’s visits and bestowed their gifts on April 1st, as March
25th occurred in Passion Week. After the adoption of the new calendar,
however, these New Year’s observances took place on January 1st, and it
was a common thing for people to forget the change of date. Pretended
presents and mock ceremonial visits became common, and the persons thus
imposed on were known as April fish, i.e., a mackerel, which, like a fool, is
easily caught. Hence, All Fools’ Day.

from my hand, causing it to alight on a ledge 260 ft. from the base, over
which it rolled and fell to the earth: supposing that 1½ seconds were

elapsed from the ball leaving my hand till it touched the earth, and what
was the acquired velocity at the moment of contact?

In one of our great public schools a master
known to successive generations of his pupils
for fifty years as “old Buggus” delighted in
surprising his boys with strange sayings and
doings. On one occasion, desirous of illustrating
a question in the arithmetic lesson, he said to a
boy, “I am a tripe merchant, and this platform is
my shop. You will come here and buy a pound
of tripe. Now, begin.”
“Please, I want a pound of tripe,” said a boy,
sauntering up. “Where’s your money?” demanded old Buggus, hoping to
put the boy out of countenance.
“Where’s your tripe?” was the ready retort; but it gained for its
unfortunate author four hours’ detention on the next holiday.

arithmetic book—“How to Become Quick at Figures”—
accidentally dropped the work of a problem; unfortunately
he mislaid the copy, and all that he remembered was that
both multiplicand and multiplier consisted of two figures.
The scattered type represented the following figures:—1, 2,
3, 3, 4, 6, 7, 8, 8, 9, 9. With the aid of a pencil and a piece of
paper the compositor managed after a while to rearrange the
figures in their proper place. What was the problem?

A very amusing story is told of a harness-maker who lived some years
ago in London. He had a handsome saddle in his shop, occupying a
conspicuous position therein. On his return from luncheon one day he
observed that the saddle was gone. Calling to his foreman, he said:
“John, who has bought the saddle?”
“I’m sure I don’t know, sir,” said the foreman, scratching his head as if
he were trying to think. “I cannot tell, and the worst part of it is, it hasn’t
been paid for. While I was at work in the back of the shop a gentleman
came in, priced it, decided to take it, told me to charge it, and throwing it
into his trap, drove off, before I could think to ask his name.”
“That was very stupid of you,” said the harness-maker, disposed to be
angry at the man’s carelessness. “Very likely we have been robbed.”
“I don’t think that sir,” said the foreman, “for I’m very sure that the
gentleman has traded here before.”
“Well, I can’t afford to lose the money,” said the harness-maker. “We’ll
have to find out who took it and send him the bill. Ah!” he added, with a
smile, after a moment’s reflection, “I have it. We’ll charge it up to the
account of every one of our customers who keep open accounts here. Those
who didn’t get it will refuse to pay, so we shall be all right.”
“The book-keeper was instructed to do this, and the bills in due course
of time went out. Some weeks later the harness-maker asked the book-
keeper if he had succeeded in discovering who the customer was.
“No, sir,” he replied, “and we never shall, I fear, sir, for about 40 people
have paid for it already without saying a word.”

TO TELL THE SPOTS ON THE
BOTTOM CARDS OF SIX HEAPS.
Allow anyone to choose six cards from a full pack. Tell him the court
cards count 10, and the other cards according to their pips. Having made his
selection, tell him to lay the chosen cards upon the table face downwards,
without allowing you to see them, and to place upon each as many cards as
pips are required to make 12. Whilst he is doing so, you should be out of the
room or blindfolded. On your return he hands you the cards left over, and
you have to tell the total number of spots on the six bottom cards.
Suppose he had chosen 10, 6, 1, K, 3 and 7, which totals 37, now on the
10, he would place two cards to make 12; on the 6, he would place 6; and
on the 1, 11 would be placed, and so on. On receiving the remaining cards
from him you pretend to be looking through them carefully, but you simply
want to know how many he has given you, which in the above example
would be 11. To this number you add 26, which gives 37, the total spots
required.
Should there not be enough cards left on hand to complete the six heaps,
you can ask him how many cards he is short of, and this number, subtracted
from 25, will give the total. It is better not to allow the person to choose six
cards right off at the beginning, but for him to shuffle and cut the pack as he
pleases, and to take the cards as they come.

A MATTER OF OPINION.
A man walks round a pole on the top of which is a
monkey. As the man moves, the monkey turns on the top of
the pole, so as still to keep face to face with the man. Now,
when the man has gone round the pole, has he or has he not
gone round the monkey?
TRY IT.
Take the number 15, multiply it by itself, and you have 225; now
multiply 225 by itself, then multiply that product by itself, and so on until
15 products have been multiplied by themselves in turn. The final product
called for contains 38,539 figures (the first of which is 1412). Allowing
three figures to an inch, the answer would be over 1070 feet long. To
perform the operation would require about 50,000,000 figures. If they can
be made at the rate of 100 a minute, a person working 10 hours a day for
300 days in each year would be 28 years on the job.

he had concluded an extensive purchase of felt, which he got so cheap that
the widow can supply hats at a more moderate charge than any house in
London. His disconsolate family will carry on his business with
punctuality.”

like a three. What do you mean, sir, by making such beastly figures?

BANK NOTE VERSE.
On the backs of bank notes one sometimes meets with strange and
peculiar sentiments. “Go, poor devil, get thee gone,” is the kind of parting
salutation most in favour; but the following is chiefly notable as a rare
instance of the bank-note rhymester parting with his money in a Christian
spirit:
Farewell, my note, and wheresoe’er ye wend,
Shun gaudy scenes, and be the poor man’s friend;
You’ve left a poor one—go to one as poor;
And drive despair and hunger from his door.
An Irish merchant, who felt annoyed at a complaining letter he received
from a customer, wrote back:—“We decline to acknowledge the receipt of
yours of the 15th.”

A country spark addressed a charming “she,”
In whom all lovely features did agree;
But being void of numbers, as doth show,
Desirous was the lady’s age to know.

69. A vessel on a 3 months’ trip has provisions for 4 months, but the
stores are served out as if the voyage had to be completed in 3 months. At
the end of 2 months, it is discovered that the voyage will take 3½ months.
To what proportion must the rations be reduced for the remaining time?
In a certain town in the North of Queensland, a class of young men was
formed to receive lessons in short methods of business arithmetic. The
teacher was endeavouring to knock into the head of a young man that the
cost of a dozen articles is the same number of shillings that a single article
costs in pence. To illustrate the rule, he gave the following example:—
“If I buy 1 dozen apples at 1d each, then the dozen will cost 1 shilling;
and if I buy 1 dozen oranges at 2 pence each, the dozen will cost 2 shillings.
Now, supposing I buy 1 dozen at 3 pence each, how much will the dozen
cost?”
Young Man (after two minutes’ reflection)—“Are they apples or
oranges?”
A DRAUGHTS PUZZLE.
70. Ten draughtsmen are placed in a row. The puzzle is to lift one up

In passing over a piece already crowned, it is to be reckoned as two pieces.

71. In the centre of a pond 20 feet square there is a small island, on
which is growing a tree. Two boys notice there is a bird’s nest on the top of
the tree, but the difficulty is to reach the island, as they have 2 short planks
that only measure 8 feet each. After a little while they hit on an ingenious
plan, and, without nailing the planks together, manage to place them so they
can reach the tree in safety. How did they do it?
Teacher—“Now, I want all the children to look at Tommy’s hands, and
see how clean they are, and see if all of you cannot come to school with
cleaner hands. Tommy, perhaps, will tell us how he keeps them so nice?”
Tommy—“Yes ’m; mother makes me wash the breakfast things every
morning.”
BRAIN-BEWILDERERS.
An amusing periodical got up by the boys of a certain college gives a
capital skit on the style of examination-papers frequently presented for the
torture of pupils. Here are a few examples:—
Supposing the River Murray to be three cubits in breadth—which it
isn’t—what is the average height of the Alps, stocks being at nineteen and
a-half?
If in autumn apples cost fourpence per pound in Melbourne, and
potatoes a shilling a score in spring, when will greengages be sold in
Brisbane at three-halfpence each, Sydney oranges being at a discount of
five per cent.?
If two men can kill twelve kangaroos in going up the right side of a
rectangular turnip-field, how many would be killed by five men and a
terrier pup in going down the other side?
If a milkmaid four feet ten inches in height, while sitting on a three-
legged stool, took four pints of milk out of every fifteen cows, what was the
size of the field in which the animals grazed, and what was the girl’s name,
age, and the occupation of her grandfather?

ARITHMETICAL THOUGHT READING.
A great deal of fun can be derived from puzzles of this nature—they are
endless in variety—and as they depend upon some principle in arithmetic
should be easily remembered.
Example 1. Think of a number, say 5
Double it 10
Add 5 15
Add 12 27
Take away 3 24
Halve it 12
Take away number first thought of—5
The answer will always be 7
Example 2. Think of a number, say 8
Square it 64
Subtract the square of the number which is
1 less than the number thought of—that
is 7—whose square is 49—leaves 15
Add 1 16
When this last number is told, halve it, and you will arrive at the
original number—8.
Example 3. Think of a number, say 9
Multiply by 3 27
Add 2 29
Multiply by 3 87
Add 2 more than the number thought of (11) 98

Multiply by 3 21

Halve it 11
Multiply by 3 33
[If product be odd] add 1 34
Halve it 17
Ask how many 9’s are in the remainder, when, of course, the reply will
be 1.
The secret is to bear in mind whether the first sum be odd or even. If
odd first time, retain 1 in the memory; if odd a second time, 2 more, making
3; to which add 4 for every 9 contained in the remainder.
In the above example, there being only one 9 in 17, this gives us 4,
which added to 3 produces the number thought of—7. When even simply
add 4 for every 9 in remainder.
HOW TO TELL THE AGE OF A PERSON.
Tell a person to write down the figure which represents the day of the
week on which he was born;—thus, 1 for Sunday, 2 for Monday, and so on;
next, the figure for the month—1 for January, 2 for February, &c.; then the
date of the month; now tell him to multiply the number thus formed by 2,
add 5, multiply by 50, and then to add his age, and from this sum to subtract
365; now you ask him for the remainder, to which you secretly add 115.
The result will be:—The first figure, the day of the week; the next, the
month in the year; the next, the date of the month; and the last, the age in
years.
Example:
A person was born on Wednesday, 11th June, 1863.

“Girls” and “Boys.”
At a school examination, the inspector set the girls to write an essay on
“Boys” and the boys to write one on “Girls.”
The following was handed in by a girl of 12:—
“The boy is not an animal, yet they can be heard to a considerable
distance. When a boy hollers he opens his big mouth like frogs, but girls
hold their tongues till they are spoken to, and then they answer respectable,
and tell just how it was. A boy thinks himself clever because he can wade
where it is deep, but God made the dry land for every living thing, and
rested on the seventh day. When the boy grows up he is called a husband,
and then he stops wading and stays out at nights, but the grew up girl is a
widow and keeps house.”
One of the boys sent in:—
“Girls are very stuck up and dignified in their manners and behaveyour.
They make fun of boys, and then turn round and love them. Girls are the
only people that have their own way every time. Girls is of several thousand
kinds, and sometimes one girl can be like several 1000 girls if she wants
anything. I don’t beleive they ever killed a cat or anything. They look out
every nite and say, “Oh, ain’t the moon lovely!” Thir is one thing I have not
told, and that is they always now their lessons bettern boys. This is all I now
about girls, and father says the less I now the better for me.”

“Girls” and “Boys.”
At a school examination, the inspector set the girls to write an essay on
“Boys” and the boys to write one on “Girls.”
The following was handed in by a girl of 12:—
“The boy is not an animal, yet they can be heard to a considerable
distance. When a boy hollers he opens his big mouth like frogs, but girls
hold their tongues till they are spoken to, and then they answer respectable,
and tell just how it was. A boy thinks himself clever because he can wade
where it is deep, but God made the dry land for every living thing, and
rested on the seventh day. When the boy grows up he is called a husband,
and then he stops wading and stays out at nights, but the grew up girl is a
widow and keeps house.”
One of the boys sent in:—
“Girls are very stuck up and dignified in their manners and behaveyour.
They make fun of boys, and then turn round and love them. Girls are the
only people that have their own way every time. Girls is of several thousand
kinds, and sometimes one girl can be like several 1000 girls if she wants
anything. I don’t beleive they ever killed a cat or anything. They look out
every nite and say, “Oh, ain’t the moon lovely!” Thir is one thing I have not
told, and that is they always now their lessons bettern boys. This is all I now
about girls, and father says the less I now the better for me.”

74. A requires a tank in size capable of holding the quantity of water
that would be caught from the roof of his house in a fall of 3 inches of rain.
The roof (commonly called a “hip-roof”) is at an angle of 45 degrees to the
wall plates. The length of house is 30 ft., breadth 24 ft., and length of ridge
to roof 6 ft. But the eaves of the iron used for the roofing were so large as to
increase its (the roof’s) dimensions by 3 inches all round, and the spouting
added another 3 inches all round. Find the number of gallons the tank
would require to contain; also dimensions of tank to be made so that its
height must exceed its diameter by no more than 12 inches?

HIS OWN GRANDFATHER.
The complication of relationship brought about by marriage is the cause
of many a family squabble, but it is seldom one hears of fatal results
attending such matters. According to an American newspaper, a resident of
Pennsylvania committed suicide a few days ago from a melancholy
conviction that he was his own grandfather.
The following is a copy of a singular letter he left:—“I married a widow
who had a grown-up daughter. My father visited our house very often, fell
in love with my step-daughter, and married her. So my father became my
son-in-law and my step-daughter my mother, because she was my father’s
wife. Some time afterwards my wife had a son; he was my father’s brother-
in-law and my uncle, for he was the brother of my step-mother. My father’s
wife—i.e., my step-daughter—had also a son; he was, of course, my
brother, and in the meantime my grandchild, for he was the son of my

88. Take 45 from 45, and leave 45 as a remainder. There are at least two
ways of doing this.
89. How can 45 be divided into 4 such parts that if you add 2 to the first
part, subtract 2 from the second part, multiply the third part by 2, and divide
the fourth part by 2, the sum of the addition, the remainder of the
subtraction, the product of the multiplication, and the quotient of the
division are equal?
90. The square of 45 is 2025, if we halve this we get 20⁄25 and 20 plus 25
equals 45. Find two other numbers of four figures that produce the same
peculiarity.
91. A mother of a family being asked how many children she had,
replied: “The joint ages of my husband and myself are at present six times

times theirs.” How many children had she?

The figures 4, 5, 6, at the angles of the large
triangle, represent respectively the above

each other, but we will induce them to meet
half-way. Thus, the Mahometans and Jews meet
at 10, the Mahometans and Christians at 9, and the Jews and Christians at
11; and by joining these totals to the opposite numbers we see they all meet
at last in Heaven (15). It should be mentioned that any numbers whatever
may be used to represent the sects, but the result will always be the same.

wished to know her height. She replied, “My height (in inches) if divided
by the product of its digits, gives as quotient 2, and the digits are inverted
by adding 27.”
“You have a bright look, my boy,” said the visitor at the school. “Yes,
sir,” replied the candid youth; “that’s because I forgot to rinse the soap off
my face this morning.”
HIS LAST WILL AND TESTAMENT.
93. A father on his death-bed gave orders in his
will that if his wife, who was then pregnant, brought
forth a son, he should inherit two-thirds of his
property, and the mother the remainder; but if she
brought forth a daughter the latter should have only
one-third, and the mother two-thirds. The widow,
however, was delivered of twins,—a boy and a girl.

Page 77
“We are greatly pained to hear of the loss sustained by your firm, and
extend to you our heartiest sympathy. We notice the circular you sent us
announcing Mr. S——’s death is lithographed by Messrs.——. We regret
that you did not see your way to let us estimate for the printing of the same.
The next time there is a bereavement in your house we will be glad to quote
you for the lithographic circulars, and are confident that we can give you
better work at less cost than anybody else in the business. Trusting that we
may soon have an opportunity of quoting you our prices, we remain, with
profound sympathy, yours truly,——.”
An American journal, describing a new counterfeit bank-note, says the
vignette is “cattle and hogs, with a church far in the distance”—a good
illustration of the world.
95. On a square piece of paper mark 12 circles as shown
in diagram. The puzzle is to divide the figure into four pieces
of equal size, each piece to be of the same shape, and to
contain three circles, without getting into any of them.
THE ORIGIN OF THE “STONE.”
Measurement of weight by the “stone” arose from the old custom
farmers had of weighing wool with a stone. Every farmer kept a large stone
at his farm for this purpose. When a dealer came along he balanced a plank
on top of a wall, and put the stone on one end of it and the bags of wool on
the other, until the weights were equal. At first the stones were of all sorts
and sizes and weights, with the result that dealers who wished to make a
living had to be remarkably knowing in their estimates of them. The many
inconveniences involved by this inequality resulted in all stones being made
of a uniform weight as far as wool was concerned. The weight of a stone of
potatoes, meat, glass, cheese, &c., all differ.
A little boy was reading in his Scottish history an account of the battle
of Bannockburn. He read as follows: “And when the English army saw the

THUNDER AND LIGHTNING CALCULATION.
96. Between the earth and a thundercloud there are four currents of air,
having a temperature of 87, 57, 47, and 37 degrees respectively. The first
current is half the depth of the second, the second half the third, and the
third half the fourth. If a peal of thunder is heard 2-3251/4256 seconds after
the lightning flash, find the depth of the fourth current and the time
occupied by the sound in passing through it.

99. A and B set out on a walking expedition at the same time—A from
Melbourne to Geelong, and B from Geelong to Melbourne. On reaching
Geelong A immediately starts again for Melbourne. Now, A arrives at
Geelong four hours after meeting B, but he reaches Melbourne three hours
after their second meeting. In what time did each perform the journey?
100. What two numbers are those of which the square of the first plus
the second equals 11, and the square of the second plus the first equals 7?
A schoolmaster, describing a money-lender, says, “He serves you in the
present tense, he lends you in the conditional mood, keeps you in the
subjunctive mood, and ruins you in the future.”
101. “How much money have I,” says a father to his son. Son replied,
“They don’t teach prophecy at our school.” “Well, they teach arithmetic, I
suppose,” rejoined the father, smartly; “if you multiply one-half, one-third,
one-fourth, one-sixth, three-quarters, and two-thirds of my money together,
the product will be 10368. Now find out how many pence I have.”
102. A person has 1260 quarters of wheat. He sells one-fifth at a gain of
5 per cent., one-third at a gain of 8 per cent., and the remainder at a gain of
12 per cent. Had he sold the whole at a gain of 10 per cent. he would have
made £23 2s. more than he did. Find the cost price of one quarter.
103. Is the word “with” ever used as a noun?

A penny at 5 per cent. compound interest from a.d. 1 to 1890 would
amount to £10,000,000,000,000,000,000,000,000,000,000,000,000, i.e., Ten
Sextillions of pounds, or more money than could be contained in One
Thousand Millions of Globes each equal to the Earth in magnitude, and all
of solid gold.
111. On a flagstaff consisting of an upright pole (6 feet of which is
underground) is a cross-yard 24 feet long; the latter is fixed at a distance of
one-third of the length of the visible part of the pole from the top; passing
from the top of the pole to the ends of the yard are ropes, forming stays
whose falls or ends reach to the ground on either side of the pole, and it is
found that these falls just reach the base of the pole. The total length of rope
in the aforesaid stays is 40 feet. Supposing that the top diameter of the pole
is one-third of that at the extreme base, and that the whole length of rope
used is 54,177 times the base diameter of the pole, what would the pole cost
at 1 penny per 100 cubic inches?

8-8 = 2-2, dividing both these equals by 2-2 the result must be equal; 8-

OPTICAL ILLUSIONS.
Illusions of the Eye are numberless, and afford a
wide field for experiment. Some people are left-eyed,
others right-eyed, and very few use both eyes equally.
It is impossible to tell how far they really do deceive
us unless they have been tested in the proper manner.
For instance, if you ask anyone to what height a bell-
topper would reach if placed on the floor against the
wall, nine times out of ten the height guessed will be
half as much again as the real height of the hat. Everyone seems to over-
estimate the proper height.
Another favourite illusion is to ask a person to mark on
the wall a height from the floor which would represent the
length of a horse’s head: here the majority guess far too little
—for a horse’s head is much longer than most people
imagine, ranging from 25 to 34 inches. In a recent
experiment 5 persons out of 6 under-estimated the proper
height.
Here are two triangles. Which is the one
whose centre is the better indicated? (It looks
like A, but it is B).
Again: Out of the two straight lines C and D
which is the longer? (By measurement we see they are both the same).
Guess, by eye-measurement only, the longest and shortest of the three
lines marked A A, B B, and C C. When you have done guessing measure,
and see how much you are out.

Which is the tallest gentleman of the three
appearing in adjoining figure?—Many would
imagine the last to be the tallest, and the first the
shortest, whereas the reverse is the case—
the last is the shortest, and the first the
tallest.
It is surprising how the eye can be
deceived, when dealing with areas or
circles. Place on the table a half-crown
and a threepenny-piece; let these be, say,
9 or 10 inches apart, and ask a friend how many
of the latter can be placed on the former—with
this proviso: the threepenny-pieces must not rest
on each other, nor must they overlap the outer
rim of the half-crown; they must be fairly within
the circumference of the larger coin. Many will
answer 6, 5, or 4, others who are more cautious
3. Try for yourself and see how many you can
put on, and you are sure to be surprised.
ARE THESE LINES PARALLEL?
The “herring-bone” figure here illustrated is
yet another proof that our eyes are faulty. The
horizontal lines appear to slant in the direction
in which the short intersecting lines are falling,
and would give one the idea that they would meet if continued, whereas
really they are parallel. The illusion is more striking if you tilt the leaf up.

of all that he had. How many had he?

PAYING A DEBT.
In an office the boy owed one of the clerks threepence, the clerk owed
the cashier twopence, and the cashier owed the boy twopence. One day the
boy, having a penny, decided to diminish his debt, and gave the penny to the
clerk, who in turn paid half his debt by giving it to the cashier, the latter
gave it back to the boy, saying, “That makes one penny I owe you now;” the
office boy again passed it to the clerk, who passed it to the cashier, who in
to go through a tollbar, and before he could get
through he had to pay a penny. He had not a
penny; he did not find a penny, nor borrow a

along the whole length of its centre. Turn one of the ends round so as to
give it a twist, and then gum the ends together. Now take a pair of scissors
and cut the circle of paper round along the line, and you will have two
circles. This is a puzzle within a puzzle, and has never been satisfactorily
explained either by scientist or mathematician.
How to Read a Person’s Character.
Tell a friend to put down in figures the year in which he was born; to
this add 4, then his age at last birthday provided it has not come in the
present year (if it has, then his age last year); multiply this sum by 1000,
and subtract 687,423. (This number is for 1899; it increases 1000 for each
succeeding year.) To the remainder place corresponding letters of the
alphabet. The result will be the popular name by which your friend is
known.
Example: A person was born in 1860, and is now 38 years of age.

123. A lends B a certain sum at the same time he insures B’s life for
£737 12s. 6d., paying annual premiums of £20; at the end of three years and
just before the fourth premium is to be paid, B dies, having never repaid
anything. What sum must A have lent B in order that he may have just
enough to recoup himself, together with 5 per cent. compound interest on
the sum lent and on the premiums?
124. I met three Dutchmen—Hendrick, Claas, and Cornelius—with
their wives—Gertruig, Catrün, and Anna; in answer to a question they told
me they had been to market to buy pigs, and had spent between them £224
11s; Hendrick bought 23 pigs more than Catrün, and Class bought 11 more
than Gertruig, each man laid out 3 guineas more than his wife. Now find
out each couple—man and wife.
CURIOUS BOOK-KEEPING.
An old tradesman used to keep his accounts in a singular manner. He
hung up two boots—one on each side of the chimney; into one of these he
put all the money he received, and into the other all the receipts and
vouchers for the money he paid. At the end of the year, or whenever he
wanted to make up his accounts, he emptied the boots, and by counting
their several and respective contents he was enabled to make a balance,
perhaps with as much regularity and as little trouble as any book-keeper in
the country.
QUICKER THAN THOUGHT.
A little boy, hearing someone remark that nothing was quicker than
thought, said: “I know something that is quicker than thought.” “What is it,
Johnny?” asked his pa. “Whistling,” said Johnny. “When I was in school
yesterday I whistled before I thought, and got caned for it, too.”
125. The number of men in both fronts of two columns of troops A and
B, when each consisted of as many ranks as it had men in front, was 84; but
when the columns changed ground, and A was drawn up with the front B
£737 12s. 6d., paying annual premiums of £20; at the end of three years and

RUNNING THROUGH HIS FORTUNE.
126. A man inheriting money spends on the first day 19s., twice that
amount on the next, and 19s. additional every day till he exhausts his
fortune by spending on the last day £190 by way of having a real good time

had he left to him at the start?
127. A shopkeeper makes on a certain article the first day a profit of 3d.,

“AWFUL SACRIFICE.”
One of those generous, disinterested, self-sacrificing tradesmen, having
stuck upon every other pane of glass in his window, “Selling-off,” “No
reasonable offer refused,” “Must close on Saturday,” offered himself as bail,
or security, in some case which was brought before a magistrate, when the
following dialogue ensued:—The magistrate asking him if he was worth
£200, “Yes,” he replied. “But you are about to remove, are you not?” “No.”
“Why, you write up, ‘Selling-off.’” “Yes, every shopkeeper is selling off.”
“You say, ‘No reasonable offer will be refused.’” “Well, I should be very
unreasonable if I did refuse such offers.” “But you say, ‘Must close on
Saturday.’” “To be sure; you would not have me open on Sunday, would
you?”

A WASTE OF TIME.
A little boy spent his first day at school. “What did you learn?” was his
aunt’s question. “Didn’t learn nothing.” “Well, what did you do?” “Didn’t
do nothing. There was a woman wanting to know how to spell ‘cat,’ and I
told her.”
An English School-boy’s Essay on Australia.
“Part of Austrailya is vague. It ust to be used by the English to keep
men on that was not bad enough to be killed. Some farms would raise as
much as five hundred thousand. The English long ago ust to send their
prisoners there when they did anything not worth hanging.
“Austrailya is a vast Country, and the biggest Island on the surface of
the Earth. It has all its bad men and they have found a great many Gold and
Diamonds there, and Sidney is one of the Chief Countries in it which is in
new south Wales.
“It used to be used for purposes of Exploration, but it has no interior,
and you can’t explore it. Sometimes it is called Antipides, because
everything is upside down there. The chief products are Wool and Gold and
other Exports and the Austrailyan eleven come from there. The Climate is
hot in the Summer and not so in the Winter, which causes drowts and
sweeps all the sheep away and the banks break.
“It was discovered by Captain Cook who captured it from the Dutch.
There are no wild Animals there except the Kangaroo, they fly through the
air with great skill and then they return again right to your feet. The natives
are coloured Black and they call themselves Aboriginels, they subsist on
bark and other food they do no work and chop wood for a miserable living
and can smell the ground like a dog. When we go there they call us new
Chums. They have no form of Worship, and pray for rain, but a belief in
Federashun because they want to be joined together.
“Their only amusement is Co-robbery. It is celebrated for Bushrangers

AN APPALLING “SUM.”
At a school, a short time back, the pupils were given, as a home lesson,
the task of subtracting from 880,788,889 the number 629 so often till
nothing remained.
The boys worked on for hours without any perceptible diminution of the
figures, and at length gave up the task in despair. Some of the parents then
tried their hands, with no better success. For, in order to work out the sum,
the number 629 would have to be subtracted 1,400,300 times, leaving 189
as a remainder.
Working 12 hours a day, at the rate of 3 subtractions per minute, it
would take over 1 year and 9 months to complete the sum which had been
set the poor lads for their home lesson.
A MILITARY LUNCHEON.
135. A certain number of Volunteers—namely, Commissioned Officers,
Non-commissioned Officers, and Privates had a dinner bill to pay; there
were, it seemed, half as many more Non-Com. Officers as Com., one-third
as many more Privates as Non-Com. Officers, and they agreed that each
Commissioned Officer should pay one-third as much again as each Non-
Com., and each Non-Com. one-fifth as much again as each Private; but 1
Commissioned and 2 Non-Com. Officers slipped away without paying their
portion (5s.), each of the others had to pay in consequence 4d. more. What
was the amount of the bill, and the number of each present?
Twice the half of 1½? Ask your friends—it bothers them.

The Problem Easily Solved.
“Do you see that row of poplars on the other bank standing apparently
at equal distances apart?” asked a grave-faced man of a group of people
standing by a river.
The group nodded assent.
“Well, there’s quite a story connected with those trees,” he continued.
“Some years ago there lived in a house overlooking the river a very wealthy
banker, whose only daughter was beloved by a young surveyor. The old
man was inclined to question the professional skill of the young rod and
level, and to put him to the test directed him to set out on the river shore a
row of trees, no two of which should be any further apart than any other
two. The trial proved the lover’s inefficiency, and forthwith he was
forbidden the house, and in despair drowned himself in the river. Perhaps
some of you gentlemen with keen eyes can tell me which two trees are
furthest apart?”
The group took a critical view of the situation, and each member
selected a different pair of trees. Finally, after much discussion, an appeal
was made to the solemn-faced stranger to solve the problem.
“The first and the last,” said he, calmly, resuming his cigar and walking
away with the air of a sage.
136.
Twice five of us are eight of us, and two of us are three,
And three of us are five of us—now how can all this be?
If that does not puzzle you I’ll tell you one thing more:
Eight of us are five of us and five of us are four.
“EXPRESSIONAL” MEASURES.
The table of measures says that 3 barleycorns make 1 inch—and so they
do. When the standards of measures were first established 3 barleycorns,
well-dried, were taken out and laid end to end, and measured an inch.

137. A lady belonging to the W.C.T.U. was endeavouring to persuade a
gentleman friend of hers to give up the drink; he replied, “I will sign the
pledge if you tell me how many glasses of beer did I drink to-day if the
difference between their number and the number of times the square root of
their number is contained in 2 be equal to 3.”
MEMORY SYSTEM.
Teacher—“In what year was the battle of Waterloo fought?”
Pupil—“I don’t know.”
Teacher—“It’s simple enough if you only would learn how to cultivate
artificial memory. Remember the twelve apostles. Add half their number to
them. That’s eighteen. Multiply by a hundred. That’s eighteen hundred.
Take the twelve apostles again. Add a quarter of their number to them.
That’s fifteen. Add to what you’ve got. That’s 1815. That’s the date. Quite
simple, you see, to remember dates if you will only adopt my system.”

138. Everyone knows that in a race on a circular track the competitor
who has the “inside” running has the least ground to cover, hence the great
desire of cyclists, jockeys, &c., to “hug the fence.”
Now a gentleman, six feet high, starts walking round the Earth on the

the father replied with the following letter:—“In promulgating your esoteric
cogitations, or articulating superficial sentimentalities, and philosophical or
pscyhological observations, beware of platitudinous ponderosity. Let your
conversation possess a clarified conciseness, compacted
Page 99
comprehensibleness, coalescent consistency, and a concatenated cogency.
Eschew all conglomerations of flatulent garrulity, jejune babblement, and
asinine affectations. Let your extemporaneous descantings and
unpremeditated expatiations have intelligibility, without rhodomontade or
thrasonical bombast. Sedulously avoid all polysyllabical profundity,
pompous prolixity, and ventriloquial vapidity. Shun double entendre and
prurient jocosity, whether obscure or apparent. In other words, speak
truthfully, naturally, clearly, purely, but do not use big words.”

be weighed. What are the weights?
143. A man going “on the spree” spends on the first day 10s. 5d., the
second 18s., the third £1 8s. 7d., the fourth £2 2s. 8d., and so on at that rate
of increase until he has spent all he had—£183 6s. 8d. How many days was
he on the spree?

got plenty of grit, and that the milk I sell is of the first water, and that my

whose encomiums I value.”

RAILWAY-SHUNTING PUZZLE.
148. A locomotive is on the main line of
railway; the trucks marked 1 and 2 are on
sidings which meet at the points, where there is
room for one truck only and not for the
locomotive. It is desired to reverse the position
of the trucks—that is, put 1 where 2 is, and 2
where 1 is, and yet leave the locomotive free on
the main line. This must be done by means of
the locomotive only, either pulling or pushing the trucks—it may be
between them, thus pulling one and pushing the other—but no truck must
move without the locomotive.
In working this puzzle out, it would be best to draw the diagram on an
enlarged scale, and have articles to represent the trucks and locomotive.

A Scotch tradesman, who had amassed, as he believed, £4000, was

again, and again declared the balance to be £6000. Time after time he cast

follows:—
“King Henry 8 was the greatest widower that ever lived. He was born at
Anne Domini in the year 1066. He had 510 wives besides children. The first
was beheaded and afterwards executed, and the second was revoked. She
never smiled again. But she said the word ‘Calais’ would be found on her
heart after death. The greatest man in this reign was Lord Sir Garret Wolsey
—named the Boy Bachelor. He was born at the age of fifteen unmarried.
Henry 8 was succeeded on the throne by his great-grandmother, the
beautiful Mary, Queen of Scots, sometimes called Lady of the Lake or the
Lay of the Last Minstrel.”

Two teachers of languages were discussing matters and things relative
to their profession.
“Do your pupils pay up regularly on the first of each month?” asked one
of them.
“No, they do not,” was the reply; “I often have to wait weeks and weeks
before I get my pay, and sometimes I don’t get it at all. You can’t well dun
the parents for the money.”
“Why don’t you do as I do? I always get my money regularly.”
“How do you manage it?”
“It is very simple. For instance, I am teaching a boy French, and on the
first day of the month his folks don’t send the amount due for the previous
month. In that case I give the boy the following exercise to translate and
write out at home:—‘I have no money. The month is up. Hast thou any
money? Have not thy parents any money? I need money very much. Why
hast thou brought no money this morning? Did thy father not give thee any
money? Has he no money in the pocket-book of his uncle’s great aunt?’
This fetches them. Next morning that boy brings the money.”

journey of 100 miles, the total cost of the eight tickets being £3 2s. 6d., find
the charge per mile for each first-class and second-class ticket.
HUMILITY.
In a certain street are three tailors. The first to set up shop hung out this

176. Four sundowners called at a station and asked for rations. “Well,”
said the manager, “I have a job that will take 200 hours to complete; if you
want to do it, you can divide the work and the money among yourselves as
you see fit.” The sundowners agreed to do the work on these conditions.
“Now, mates,” said the laziest of them, “it’s no good all of us doing the
same amount of work. Let’s toss up to see who shall work the most hours a
day, and who the fewest. Then let each man work as many days as he does
hours a day.” This was agreed to; but the proposer took good care that
chance should designate him to do the least number of hours of work. How
were the 200 hours put in so that each man should work as many hours as
days, and yet no two men work the same number of hours?

177. On multiplying a certain number by 517 a result is obtained greater
by 7,303,535 than if the same number had been multiplied by 312. How
much greater still would be the result if 811 were the multiplier instead of
312?

178. Six ears of corn are in a hollow stump. How long will it take a
squirrel to carry them all out if he takes but three ears a day?
NUMBER 7.
The number 7 has always been considered the most sacred of all our
figures. Its prominence in the Scriptures is very remarkable, from Genesis
—where we read that the seventh day was consecrated as a day of rest and
repose—to Revelations—where we find the seven churches of Asia; seven
golden candlesticks; the book with seven seals; the seven angels with seven
trumpets; seven kings; seven thunders; seven plagues, &c., &c., its frequent
occurrence is most striking.
The Ancients paid great respect to the seven mouths of the Nile. The
seven rivers of Vedic India; seven wonders of the world; seven precious
stones; seven notes of music; seven colours of the rainbow, &c., &c. The
“Lampads seven that watch the Throne of Heaven” led the Chaldeans to
esteem the unit 7 as the holiest of all numbers, thereupon they established
the week of seven days, and built their temples in seven stages. The temples
and palaces of Burma and China are seven-roofed.
In modern times this number has kept up its reputation. Shakespeare
paid special regard to it; the “seven ages” and every multiple of it is
supposed to be a critical or important period in one’s life.

systematically into the swindling business, and engage in wholesale
pecuniary transactions without a shilling of his own, the first thing he

From what may occasionally be seen of the reports of the proceedings
in bankruptcy, it is found that well kept books are regarded as quite a test of
Page 112
honesty, and though assets may have disappeared or never have existed,
though large liabilities may have been incurred without any prospect of
payment, the bankrupt will be complimented on the straight look of his
dealings, if he has shown himself a good book-keeper.
To common apprehension it would seem that well kept books would
only help to show a reckless trader the ruinous result of his proceedings,
and that while the man without books might flatter himself that all would
come out right at last, the man with exact accounts would only get into hot
water with his eyes open. If a man may trade on the capital of others
without any of his own, and get excused on the ground that he has kept his
books correctly, it is difficult to see why a thief who steals purses, &c., may
not plead in mitigation of punishment that he has carefully booked the
whole of his transactions.
It would be interesting to know the effect of producing a ledger on a
trial for felony, as well as curious to observe whether a burglar would be
leniently dealt with on the ground that his house-breaking accounts gave
proof of his experience in the science of “double-entry.”
Therefore it would be well for those interested to procure copies of “Re
Accounts” and “Advanced Thought on Accounts.”

A commercial traveller handed a merchant upon whom he had called a

partnership.

THE SHARP SELECTOR.
183. A selector rented a farm, and agreed to give his landlord two-fifths
of the produce, but prior to the time of dividing the corn the selector used
45 bushels. When the general division was made it was proposed to give to
the landlord 18 bushels from the heap in lieu of the share of the 45 bushels
which the tenant had used, and then to begin and divide the remainder as
though none had been used. Would this method have been correct?
A GOOD “AD.”
A member of a certain firm appeared in a law court with a complaint
that his partner would sell goods at less than cost price, and he desired to
have him restrained. The defendant utterly denied the charge, and the case
was adjourned for a fortnight. As the plaintiff went out of court he
exclaimed in a tragic tone: “Then the sacrifice must still go on!” and “I’ll be
ruined!” The story was noised abroad, and the result was that the shop was
besieged by customers every day. There the case ended, for at the end of the
fortnight the plaintiff failed to appear in court, having accomplished his
purpose—advertisement.

travel, and at what speed must the latter travel after they have met, in order
that they both may reach their destinations at the same time?
“GOOD ENOUGH!”
“Will you give me a glass of beer, please?” asked a rather seedy-looking
fellow with an old but well-brushed coat and almost too shiny a hat. It was
produced by the barmaid, frothing over the edge of the tumbler.
“Thank you,” said the recipient, as he placed it to his lips. Having
finished it in a swallow, he smacked his lips and said, “That is very good
beer—very! Whose is it?”
“Why, that Perkins’s——”
“Ah! Perkins’s, is it! Well, give us another glass.”
It was done; and holding it up to the light and looking through it, the
connoisseur said:—
“’Pon my word, it is grand beer—clear as Madeira! What a fine color! I
must have some more of that; give me another glass.”
The glass was filled again, but before putting it to his lips the imbiber
said:—

The well known author of several works on account-keeping, Mr.
Yaldwyn, tells a rather good thing which actually occurred in New Zealand
some time back. Mr. Yaldwyn was at the time engaged examining the books
Page 116
in one of the offices in a country town, and enquired from one of the clerks
standing near if the ledger were posted. The person appealed to answered
that “he didn’t know,” whereupon Mr. Y. said that he required it done, and
with as little delay as possible. A few minutes later the same individual
came rushing in and informed him that the ledger was “posted.” Such a
piece of “lightning book-keeping” so surprised Mr. Y. that he further
questioned the man, who replied “You said you wanted the ledger posted,
and, begorra, I posted it.” It then dawned upon Mr. Yaldwyn that the clerk,
who was an Irishman, had actually posted the book in the post office!
THEY MANAGED IT.
191. Billy and Tommy, two aboriginals, killed a kangaroo in the bush,
and began quarrelling over the weight of the animal. They had no proper
means of weighing it, but, knowing their own weights, Billy 130 lbs. and
Tommy 190 lbs., they placed a log of wood across a stump so that it
balanced with one on each end. They then exchanged places, and, the
lighter man taking the kangaroo on his knees, the log again balanced. What
was the weight of the kangaroo?
192. A son asked his father how old he was, and received the following
answer: “Your age is now one quarter of mine, but five years ago it was

THE PASSING TRAINS PUZZLE.
194. If through passenger trains running to and from New York and San
Francisco daily start at the same hour from each place (difference of
longitude not being considered) and take the same time—seven days—for
the trip, how many such trains coming in an opposite direction will a train
leaving New York meet before it arrives at San Francisco?
THE SCHOOL-TEACHER “CAUGHT.”
Two of our Public Schools were engaged playing a football match one
afternoon. The head master of one of them had generously given the boys a
half-holiday; but the gentleman who held the same capacity in the other
school, not being an ardent admirer of Australia’s national game, refused to
do so. When school assembled in the afternoon, a boy volunteered to ask
the master for the desired holiday. When the question was put, he firmly
answered, “No, no!” whereupon the bright youth called out: “Hurrah! we
have our holiday; two negatives make an affirmative.” The teacher was so
pleased at the boy’s sharpness that he dismissed the school right away.

196. A man starts to walk from a town, A, to a town B, a distance by
road of 16 miles, at the rate of 4 miles an hour. There is a point C on the
road, at which the road to B leads away to the right, and another road at
right-angles to this latter goes to the left, “to no place in particular.” The
unwary traveller gets on to this left hand road, and is walking for 2¼ hours
since he left A, before he finds out his mistake, and he resolves not to go
back to the junction, which is five miles away, but makes straight across the
bush to B, and strikes it exactly. How long did it take to go from A to B?
GAMBLING.
197. Three friends, A, B, and C, sit down to play cards. As a result of
the first game, A lost to each of B and C as much money as they started to

198. A, who is a dealer in horses, sells one to B for £55. B
very soon discovers that he does not require the animal, and
sells him back to A for £50. Now, A is not long in finding
another customer for the horse: he sells it to C for £60. How
much money does A make out of this transaction?
This question has been the cause of endless discussion
and argument.
It might be as well to state that when A first sold the
horse to B he neither made nor lost any money by the deal.

road, at which the road to B leads away to the right, and another road at
right-angles to this latter goes to the left, “to no place in particular.” The
unwary traveller gets on to this left hand road, and is walking for 2¼ hours
since he left A, before he finds out his mistake, and he resolves not to go
back to the junction, which is five miles away, but makes straight across the
bush to B, and strikes it exactly. How long did it take to go from A to B?

197. Three friends, A, B, and C, sit down to play cards. As a result of
the first game, A lost to each of B and C as much money as they started to

Two concrete numbers cannot be multiplied together.
In the example just given, 2s. multiplied by 3, we see it simply means to
write down 2s. three times, and by addition we discover the answer to be 6s.
Suppose the reader lent a friend 2s. on Monday, 2s. on Tuesday, and 2s. on
Wednesday, he has lent 2s. three times, making 6s. lent in all.
Now, we will attempt to multiply 2s. by 3s., but it is impossible to
comprehend how many times is 3s. times. The answer to 2s. x 3s. usually
given is 6s. On the same lines, we multiply 9d. by 10d., and our answer is—
90d., that is 7s. 6d.—a greater product than 2s. multiplied by 3s.
Although it is stated that two concrete numbers cannot be multiplied
together, it should be borne in mind that we can multiply yards, feet, and
inches, by yards, feet, and inches (length by breadth), which will result in
square or cubic measure: 12 inches make 1 foot, and 3 feet make one yard,
144 square inches make 1 square foot, &c. 12 pence make 1 shilling, but
how many square pence make 1 square shilling?
The argument generally brought forward in favour of the performance
of this problem is, that when the Rule of Three is applied to financial
questions (such as interests, &c.) money is multiplied by money.

The multiplication in the above is in appearance only, for all we get in
the Rule of Three is the ratio between the sums of money and this ratio is an
abstract number, and not concrete. On examination we find the ratio
between £10 and £20; that the latter is double, or two times as much as the
former, and not £2 times more than it.
We extend a general invitation to all our readers who hold a different
opinion to multiply three pints of Dewar’s Whisky by 6 quarts of soda-

conscientious grounds, we will extend the invitation to three cups of tea by
six spoonfuls of sugar. And if any of them have a few pounds (say £10) in
the Savings Bank we would advise “Don’t add any more deposits, but wait
till you have £2, then proceed to the bank and multiply the £10 by the £2,
and prove to the teller that you have £20 to your account. Be careful to take
no less a sum than £2, or the result might be a little surprising, for if you
take only £1, the teller might argue after he has received your sovereign that
“ten ones are ten,” and then your £10 would remain the same.”

EUCLID.—The Famous Forty-Seventh.
“In any right-angled triangle, the square
which is described upon the side opposite to the
right-angle is equal to the squares described
upon the sides which contain the right-angle.”
Here is a simple way of proving this
proposition. Although perhaps not exactly
scholastic, it is none the less interesting.
Draw an exact square, whose sides measure
7 in.; then divide it into 49 square inches.
Having done this, cut the figure in following the Fig. 1.
big lines as shown by Fig 1. It will be observed
that C is a complete square, and that A and B
will form a square: but as D is 1 in. short of being a square, it is necessary
to cut a square inch and add it on.
Then construct a right-angled triangle as shown by Figure 2.
We then see that the sum of the two small squares is equivalent to the
large square.
D contains 9 small squares.

And as we see that C has 25 small squares, it
is thus proved that the sum of the squares upon
the sides which contain the right angle are equal
to the squares upon the side opposite the right

219. A certain gentleman, who was employed in one of
our city offices, purchased The Doctrine of Chance, which
he studied in his spare time, with the result that he sent in his
resignation to the head of the firm in order to try his luck on
the racecourse.
At the first meeting he attended, there were only three
horses in a race. His brother bookmakers were crying out the
odds—
“Two to 1 bar one.”
The odds on this latter horse which was “barred” he discovered to be 6
to 4 on. He determined to give far more liberal odds, and called out—
“Even money, 2 to 1, and 3 to 1.”
How could he give such odds, and yet win £1, no matter which horse

water, which, at 277·274 inches to the gallon, is 22622·5 gallons. The

he studied in his spare time, with the result that he sent in his
resignation to the head of the firm in order to try his luck on
the racecourse.
At the first meeting he attended, there were only three
horses in a race. His brother bookmakers were crying out the
odds—
“Two to 1 bar one.”
The odds on this latter horse which was “barred” he discovered to be 6
to 4 on. He determined to give far more liberal odds, and called out—
“Even money, 2 to 1, and 3 to 1.”
How could he give such odds, and yet win £1, no matter which horse
wins the race?
AN INCH OF RAIN.
How many people really consider what is contained in the expression?
Calculated, it amounts to this:—An acre is equal to 6,272,640 square
inches; an inch deep of water on this area will be as many cubic inches of
water, which, at 277·274 inches to the gallon, is 22622·5 gallons. The
quantity weighs 226,225 lbs. Thus, an “inch of rain” is over 100 tons of
water to the acre.

“THE EVIDENCE YOU NOW GIVE, &c., &c.”
221. Smith, Brown, and Jones were witnesses in a law case. The first-
named gentleman swore that a certain thing occurred; Brown, on being
called, confirmed Smith’s statement, but Jones denied it. They are known to
tell the truth as follows:—
Smith, once in 3 times
Brown, " " 5 "
Jones, " " 10 "
What is the probability that the statement is true?
When a man attains the age of 90 years, he may be termed XC-dingly

Examination Gems.
A school examination room might not to a casual observer seem to be a
very likely place to find entertainment. However, the answers often given
by pupils are sometimes excruciatingly funny, as is proved by the
following:—
Definitions.
Function.—“When a fellow feels in a funk.”
Quotation.—“The answer to a division sum.”
Civil War.—“When each side gives way a little.”
The Four Seasons.—“Pepper, mustard, salt and vinegar.”
Alias.—“Means otherwise—he was tall, but she was alias.”
Compurgation.—“When he was going to have anything done to him,
and if he could get anyone to say, ‘not innocent,’ he was let off.”
The Equator.—“Means the sun. Suppose we draw a straight line and the
sun goes up to the top, then it is day, and when it comes down it is night.”
Precession.—“(1) When things happen before they take place. (2) The
arrival of the equator in the plane of the ecliptic before it is due.”
Demagogue.—“A vessel that holds beer, wine, gin, whisky, or any other
intoxicating liquor.”
Chimera.—“A thing used to take likenesses with.”
Watershed.—“A place in which boats are stored in winter.”
Gender.—“Is the way whereby we tell what sex a man is.”
Cynical.—“A cynical lump of sugar is one pointed at the top.”
Immaculate.—“State of those who have passed the entrance
examination at the University.”
Frantic.—“Means wild. I picked up some frantic flowers.”

History.
“Without the uses of History everything goes to the bottom. It is a most
interesting study when you know something about it.”
“Oliver Cromwell was a man who was put into prison for his
interference in Ireland. When he was in prison he wrote ‘The Pilgrim’s
Progress,’ and married a lady called Mrs. O’Shea.”
“Wolsey was a famous General who fought in the Crimean war, and
who, after being decapitated several times, said to Cromwell, ‘Ah, if I had
only served you as you have served me, I would not have been deserted in
my old age.’ He was the founder of the Wesleyan Chapel, and was
afterwards called Lord Wellington. A monument was erected to him in
Hyde Park, but it has been taken down lately.”
“Perkin Warbeck raised a rebellion in the reign of Henry VIII. He said
he was the son of a Prince, but he was really the son of respectable people.”
Which do you consider the greater General, Cæsar or Hannibal? “If we
consider who Cæsar and Hannibal were, the age in which they lived, and
the kind of men they commanded, and then ask ourselves which was the
greater, we shall be obliged to reply in the affirmative.”
Why was it that his great discovery was not properly appreciated until
after Columbus was dead? “Because he did not advertise.”
What were the slaves and servants of the King called in England?
“Serfs, vassals, and vaselines.”
Divinity.
Parable.—“A heavenly story with no earthly meaning.”
“Esau was a man who wrote fables, and who sold the copyright to a
publisher for a bottle of potash.”
What is Divine right? “The liberty to do what you like in church.”
Repugnant.—“One who repugs.”

A person having in one hand a piece of gold, and
in the other a piece of silver, you may tell in which
hand he has the gold, and in which the silver, by the
following method:—
Some even number (such as 8) must be given to
the gold, and an odd number (such as 3) must be given
to the silver; after which, tell the person to multiply
the number in the right hand by any even number
whatever, and that in the left hand by an odd number;
then bid him add together the two products, and if the whole sum be odd,
the gold will be in the right hand and the silver in the left; if the sum be
even, the contrary will be the case.
To conceal the artifice better, it will be sufficient to ask whether the sum
of the two products can be halved without a remainder—for in that case the
total will be even, and in the contrary case odd.
222. Which is the heavier, and by how much—a pound of gold or a
pound of feathers; an ounce of gold or an ounce of feathers?
223. Plant an orchard of 21 trees, so that there shall be 9 straight rows
with 5 trees in each row, the outline to be a regular geometrical figure.

224. A person paid a debt of £5 with sovereigns and half-crowns. Now,
there were half the number of sovereigns that there were half-crowns. How
many were there of each?

On the right hand of 2 place 1, add them together and place 3 under the 1;
the 3 added to 3 = 6, which place under the 3, and so on; this gives the
second column. The third is found from the second in a similar way. By the
triangle we can determine how many combinations can be made, taking any
number at a time out of a larger number. For instance, a group of 8
gentlemen agreed that they should visit the Crystal Palace 3 at a time, and
that the visits should be continued daily as long as a different three could be
selected. In how many days were the possible combinations of 3 out of 8
completed?
Method: Look down the first column till you come to 8, then see what
number is horizontal with it in the third column, viz., 56. (For the method
usually adopted for working out calculations like the above, see Doctrine

KEEPING UP STYLE.
236. A certain hotelkeeper was never at a loss to produce a large
appearance with small means. In the dining-room were three tables,
between which he could divide 21 bottles of wine, of which 7 only were

each table had the same number of bottles and the same quantity of wine.

A DOMINO TRICK.
Ask the company to arrange the whole set of dominoes whilst you are
absent in any way they please, subject, however, to domino rules—a 6
placed next to a 6, a 5 to a 5, and so on. You now return and state that you
can tell, without seeing them, what the numbers are at either end of the
chain. The secret lies in the fact that the complete set of 28 dominoes,
arranged as above-mentioned, forms a circle or endless chain. If arranged in
a line the two end numbers will be found to be the same, and may be
brought together, completing the circle. You privately abstract one domino
(not a double), thus causing a break in the chain. The numbers left at the
ends of the line will then be the same as those of the “missing link” (say the
3-5 or 6-2.) The trick may be repeated, but you must not forget to exchange
the stolen domino for another.

An Irishman who had lately arrived in the colony was employed as
handy man at one of our large suburban mansions. The lady of the house,
hearing that some midnight thief had walked off with some of her prize
poultry, desired Pat to count them as speedily as possible and to inform her
how many there were; he accordingly left off cleaning the buggy, and
proceeded to enumerate the feathered bipeds. The lady, getting impatient of
waiting for him, repaired to the poultry yard, and noticing him chasing a
small chicken, enquired, “Pat, whatever are you doing!” when the Irishman
replied; “I’ve counted all the chickens except this one; but the little varmint
won’t stand still till I count him.”

to have the diamonds re-set, and fearing that the
jeweller might be dishonest he counted the diamonds,
and found that they numbered 7 in three different
ways. Now, the jeweller stole two diamonds, but
arranged the remainder so that they counted 7 each
way as before. How was it done?

hearing that some midnight thief had walked off with some of her prize
poultry, desired Pat to count them as speedily as possible and to inform her
how many there were; he accordingly left off cleaning the buggy, and
proceeded to enumerate the feathered bipeds. The lady, getting impatient of
waiting for him, repaired to the poultry yard, and noticing him chasing a
small chicken, enquired, “Pat, whatever are you doing!” when the Irishman
replied; “I’ve counted all the chickens except this one; but the little varmint
won’t stand still till I count him.”

THE CAMEL PROBLEM.
247. An Arab Sheik, when departing this life, left the whole of his
property to his three sons. The property consisted of 17 camels, and in
dividing it the following proportions were to be observed:—
The oldest son was to have one-half of the camels, the second son one-
third, and the youngest son one-ninth; but it was provided that the camels
were not, on any account, to be injured, but to be divided as they were—
living—between the three sons.
Thereupon, a great argument ensued. The eldest son claimed 8½ camels.
The second insisted upon receiving 5⅔ of a camel; while the youngest son
would not be comforted with less than 1 8⁄9 of a camel. The Cadi (or Judge)
happened to appear on the scene. To him the matter was explained. Without
a moment’s hesitation he gave his decision—a decision by which the claims
of all three contestants were fully satisfied.

Ask a friend how many penny stamps make a dozen? He will reply,
“Why, twelve, of course.” Then ask again, “Well, how many half-penny

Before he settles his account with nature, man charges the debit of his

THE PUZZLE ABOUT THE “PROFITS.”
Perhaps there is no form of commercial calculation so confusing and so
little understood as that of mercantile profits. It might surprise many to
state, nevertheless it is perfectly true, that it is impossible to buy goods and
sell them to show a profit as great as 100 per cent.
The correct method to calculate profit is to reckon on the return—the
price received for the goods sold—not on the cost price, and as it is
impossible to sell goods at 100 per cent. discount, so also goods cannot be
sold to show that percentage of profit, unless they actually cost nothing.
Some time ago, in New Zealand, a well-known boot manufacturer had a
“GREAT DISCOUNT SALE.“ He had large posters displayed on the
windows of his shops, and advertisements in the newspapers, announcing
the fact that 5s. in the £ would be allowed as discount to all customers. The
profit he usually obtained in the ordinary way of trade was 25 per cent., and
having had a good season, he was prepared to sell off the balance of his
stock at cost price. The selling price of his goods was marked in plain
figures. A pair of boots which cost him 8s. was marked 10s., thus showing a
profit of 2s., which he considered to be 25 per cent. (2s. being a quarter of
8s.) Instructions were issued to all his employees engaged in selling to
deduct a quarter from the marked price, the result being that a pair of boots
which cost 8s., and marked 10s., was being sold at 7s. 6d. (2s. 6d., the
quarter of the marked price being deducted from 10s.) Although he

Page 144
imagined he was getting 25 per cent. profit, he was in reality receiving only
20 per cent. It was not long before the posters were altered, announcing that
4s. in the £ would be allowed to his customers.
The following question was asked some little time ago;—If a chemist
sold a bottle of medicine for 2s. 6d., which cost him 2½d., what percentage
would be his profit?
Many work out the problem and answer 1100 per cent., but this answer
is incorrect. He received 2s. 6d. for that which cost him 2½d., accordingly
there was a profit of 2s. 3½d. We must now find out what percentage is the
latter amount of the selling price, 2s. 6d., and we discover that it is 91⅔ per
cent.

“PUNCH’S” MONEY VAGARIES.
The early Italians used cattle as a currency instead of coin (thus a bull
equals 5s.) and a person would send for change for a thousand pound
bullock, when he would receive 200 five pound sheep. If he wanted very
small change there would be a few lambs amongst them. The inconvenience
of keeping a flock of sheep at one‘s bankers’, or paying in a short-horned
heifer to one’s private account led to the introduction of bullion.
As to the unhealthy custom of sweating sovereigns, it may be well to
recollect that Charles I., the earliest Sovereign, who was sweated to such an
extent that his immediate successor, Charles II., became one of the lightest
Sovereigns ever known in England.
Formerly every gold watch weighed so many carats, from which it
became usual to call a silver watch a turnip.

A Federal Problem.
It is well known to our readers that paper money—such as pound notes
—issued in one colony are depreciated in another; thus a one pound note of
N.S.W. is only worth 19s. 6d. in Victoria, and vice versa. Some time ago a
rather ’cute individual in Wodonga, on the Victorian side of the border,
bought a drink in a local hotel with a Victorian note, and received in change
a N.S.W. note, which was worth then and there only 19s. 6d.; he thereupon
crossed the Murray to Albury on the New South Wales side, bought another
drink for sixpence with his N.S.W. note, and received a Victorian note equal
to 19s. 6d. in change. He travelled backwards and forwards during the day,
getting his twentieth and last drink in Albury, on the N.S.W. side,
whereupon he returns to Wodonga with a Victorian pound note still to his
credit. He thus paid for all his drinks, which amounted to ten shillings. Who
lost the money?
We cannot advise readers to “go thou and do likewise,” for the simple
reason that such a proceeding would now be impossible, as exchange is no

The sum was “If a couple of fat ducks cost 19s., how many can he get
for £72 10s. 9d.” The dictation for Class III. began “Now as a lion prowling

mixed. One little girl’s dictation began “Now a couple of ducks prowling

Ask a person if Christmas Day and New Year’s Day come in the same
year. The answer generally given is “Of course not, Christmas comes in this

Another question that often puzzles many. Have we had more Christmas
days than Good Fridays? The usual answer is “No, both the same.”

Dods, architect, and the engraving was done in Brisbane by Messrs. Randle
Bros., the well-known engravers, of Elizabeth Street.
A Puzzle in Book-keeping.
277. A firm appointed an agent to do business on their account, and
gave him £32 17s. in cash for expenses, &c., and also supplied him with a
stock of goods, the value wholesale being £57 14s.; while in a distant town
he bought a job lot of goods for £59 19s., which he paid cash for out of
what he had realised on his first stock. He still continued to sell, but very
soon after the firm called him in, and desired him to close his account and
hand in a full statement.
His total retail sales amounted to £102 17s., and he returned goods to
the value of £31 17s., his expenses had been £25.
Question—What does the firm owe the agent, or the agent owe the
firm?

thousands of replies, not more than 5 per cent. were correct. It is a question
that individuals not conversant with book-keeping would be as likely to
solve correctly as the expert. For the convenience of those who are

(93) The difficulty is to determine what would have been the will
of the testator had he foreseen that his wife would be
delivered of twins. As he desired that in case his wife brought
forth a son he should have ⅔ of his property, and the mother
⅓, it follows that his intention was to give his son a sum
double to that of the mother; and as he desired in the other
case that if she brought forth a daughter the mother should
have ⅔ and the daughter ⅓, there is reason to conclude that he
intended the share of the mother to be double that of the
daughter; consequently, to unite these two conditions, the
heritage must be divided in such a manner that the son may
have twice as much as the mother, and the mother twice as
much as the daughter. Thus we get—
Son’s share, £4000

(113) To explain this often causes much confusion. We must take a
simple illustration: I have a garden containing 10
appletrees, all bearing fruit. Now, there are more trees than
any tree has apples on it; there must be at least 2 trees
having the same number of apples—for instance, if No. 1
tree has 1 apple, No. 2 has 2, and so on to No. 9; when we
come to No. 10 tree, it must have the same as one of the
other trees, as it could not have 10 or more according to our
first supposition.

including outdated equipment. Many small donations ($1 to $5,000) are
particularly important to maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United States.
Compliance requirements are not uniform and it takes a considerable effort,
much paperwork and many fees to meet and keep up with these
requirements. We do not solicit donations in locations where we have not
received written confirmation of compliance. To SEND DONATIONS or
determine the status of compliance for any particular state visit
www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where we have
not met the solicitation requirements, we know of no prohibition against
accepting unsolicited donations from donors in such states who approach us
with offers to donate.
International donations are gratefully accepted, but we cannot make any
statements concerning tax treatment of donations received from outside the
United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation methods
and addresses. Donations are accepted in a number of other ways including
checks, online payments and credit card donations. To donate, please visit:
