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. 



The other day he took in $6.60 and 

 reshod three men, four women and two 

 children. Can you tell how much he 

 chargestorepairapairof children's shoes? 



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."
