ANSWER THIS.

217. Suppose it were possible for a man in Sydney to start on Sunday

noon, January 1st, and travel westward with the sun, so that it might

be in his meridian all the time, he would arrive at Sydney next day

at noon, Monday, Jan. 2nd. Now, it was Sunday noon when he started,

it was noon with him all the way round, and is Monday noon when he

returns. The question is, at what point did it change from Sunday to

Monday?

218. Start with 1 and keep on doubling for eight times, thus giving

nine numbers, and arrange them in a square that when multiplied

together, horizontally, vertically, or diagonally, the product of

each row will be the cube of the number which must go in the centre

of the square.

The happiest year in a man’s life is 40; for then he can XL.

Bound to Win!

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

wins the race_?
