���A Daisy Game
Here is a version of the "One I love two I love" Daisy Game which involves a neat little puz- zle. You see the young people take turns in plucking the petals, the victorious player taking the last petal and leaving the "Old Maid" stump with his or her opponent. The player has a choice of removing one or two of the petals at each play, provided the two are side by side. For example, the first player might take petal 13, or i and 2, but not 2 and 13, since they are not together.
The game may be played with small buttons or other markers laid upon the petals until all are covered. If your opponent started by covering i and 2, what would be your play to make sure of a win?
While You Wait
O'Sullivan, the cobbler, who shoes his customers "While you wait," says he can repair five pairs of men's boots in the same time that it takes to fix six pairs of women's shoes, and that it takes the Same time to overhaul five pairs for the children as it does three pairs for the women, so he charges according to the time consumed.

��Reversing Magic Squares
"Let us have a little talk about magic squares," said the schoolmistress. "The arrangement of numbers in the form of squares, so that they will add up the same amount in every column, as well as in the two diagonals, is without doubt the oldest of mathematical puzzles. It was held in great veneration by the Egyptians; and the Pythagoreans, to add more efifici- ency and virtue to the magic square, dedicated it to the then known seven planets.
"Here we have the simplest form of the magic square, this being capable of extension ad infinitum. Now, since there is nothing new to be presented about magic squares let us take a contrary view of the magic square principle and imag- ine an arrangement of figures in square form that will not give two like totals in the 8 rows. Juggle the figures about in any manner you wish to bring about the 8 different totals, but do not disturb the center 5.
"There is another little puzzle sug- gested by the lines forming the squares. "I want you to show how the diagram of 9 little squares may be constructed of 4 separate continuous lines of similar length, which means that no lines must cross. There you have two puzzles to work out."
