If the blindfolded French soldier succeeds in cutting 

 the string, he gets the package of tobacco suspended 



Saws Without Teeth to Cut 

 Through Metal 



NOT so very long ago the dis- 

 covery was made in Ger- 

 many that metals could be sawed 

 easier and quicker with rapidly 

 revolving smooth disks of steel 

 than with toothed circular saws. 

 It was found that the cutting 

 was done by the heat generated 

 by the friction of the edge of 

 the disk against the metal. The 

 metal is melted at the point of 

 contact, while the steel of the 

 disk, being cooled by the air, 

 does not reach the melting point. 

 The disks need no sharpening 

 and do not wear out so quickly 

 as the toothed saws heretofore 

 used for cutting metal. The 

 faster the disk revolves, the 

 greater the amount of heat gen- 

 erated, and the quicker the job. 



Cut the String, Blindfolded, and 

 Win a Package of Tobacco 



THERE are times when the soldiers in 

 their camps or cantonments may 

 give themselves up to rest or pleasure. 

 After all, men are but boys grown up 

 and must have their recreation. Realizing 

 this, the military authorities in France 

 provide as much entertainment as 

 possible for the men off duty, but 

 as a rule the men must rely 

 for their amusement upon 

 their own resources. Games 

 of every kind are played. 

 The illustration shows 

 one of the favorite forms 

 of a blindfolding game 

 played by soldiers in 

 their leisure hours. 

 Strings are stretched 

 from tree to tree and 

 from these strings pack- 

 ages of tobacco are sus- 

 pended. The player is 

 blindfolded and pro- 

 vided with a pair of 

 scissors. With one hand 

 he seeks to cut the string 

 from which a package of 

 tobacco is suspended. If he 

 succeed the tobacco is his. 



Bees built this little church 

 after their owner's plan 



Introducing the Busy Honey Bee — 

 Ecclesiastical Architect 



FOR centuries bees have excited won- 

 der and admiration. Their archi- 

 tectural skill is dwelt on over and over 

 again. But did anyone ever hear of 

 their building a church? It's been 

 done. The accomplished and cultured 

 swarm of superbees that did this 

 belong to Mr. George F. Bower- 

 sox, of Portland, Indiana. 

 Unfortunately we cannot 

 give the bees credit for 

 originating the idea. Mr. 

 Bowersox did that. He 

 made a framework of 

 light laths and covered 

 it in so that the bees 

 wou'd consent to use 

 it as a hive. They 

 industriously filled in 

 all the spare space with 

 comb, which is precisely 

 what their owner wanted. 

 The result is that they 

 have allowed themselves 

 to be beguiled into con- 

 structing a church, which, as 

 can be seen from our illus- 

 tration, is a really attract- 

 ive piece of architecture.
