turn, cannot happen until after the dedent 

 spring has been compressed and the dedents 

 dropped into the lower dedent cavity. 



Notwithstand- 

 ing the fact that 

 the detonating 

 head is capable 

 of causing the in- 

 stant explosion of 

 the projectile, it 

 is in reality a 

 harmless piece of 

 mechanism until 

 it leaves the muz- 

 zle of the gun. 

 In fact, a pretty 

 heavy blow of a 

 sledge hammer 

 could be given 

 this detonating 

 head without any 

 danger of explod- 

 ing the projectile. 

 In the illustration 

 at the right is 

 shown the various 

 parts of the 

 mechanism and 

 their relation to 

 each other.

GRAZE PELLET

PERCUSSION PELLET

The graze pellet fits loosely into the fuse body and is held 

 in position by a small block of metal known as a centrifugal 

 bolt which fits into a transverse hole in the body and pro- 

 trudes over the shoulder of the graze pellet. Behind this 

 centrifugal bolt and holding it in place is the upper dedent. 

 This is a simple rod with a ball end fitted into a cup-shaped 

 receptacle in the lower and larger dedent. Under the lower 

 dedent is a coil spring simply stiff enough to hold the lower 

 dedent up against the shoulder formed between the lower 

 and upper dedent holes, at the left of the illustration above 



New Vest Attachment to 

 the Trousers in Place 



Hold 



ANEW attachment for the vest 

 holds t<he trousers in the proper 

 position and prevents the vest, from 

 "riding up." Four strong loops are 

 sewed to the vest on the inside so as 

 to be invisible; these then 

 pass around the belt of 

 the trousers and fasten with 

 a clasp. When the vest is 

 buttoned the trousers and 

 vest are held in position so 

 as to look neat; if desired 

 the belt may be worn loose 

 so as to allow ease of 

 movement and prevent 

 binding. The attachment 

 is also useful to those 

 whose work requires con- 

 siderable bending and 

 stooping and causes the 

 shirt gradually to work up. 

 The principal argument 

 against this attachment is 

 that the vest would have to 

 be worn summer and winter. 



This belt holds the vest down 

 and the trousers up and keeps 

 the shirt where it belongs 



T is a mistake to 

 state that all the 

 umbrella handles, 

 with their kinks and 

 twists and bends, 

 are freaks of na- 

 ture; they 

 are, on the 

 contrary, the 

 result of care- 

 ful training 

 on the part 

 of some um- 

 brella farmer. 

 A moment's 

 thought and 

 you will ad- 

 mit that, in 

 all your ram- 

 bles through 

 the woods, 

 you never 

 saw anything 

 like the han- 

 dles on dollar 

 umbrellas ob- 

 tainable in 

 the city. 



In France there is a plantation of several 

 hundred acres devoted entirely to the rais- 

 ing of umbrella handles, canes, and 

 riding whips. The artful handle grower 

 cuts the trees a little above the ground 

 evel and a number of saplings sprout 

 from the roots. Then the buds of 

 these sprouts are nipped off. 

 By cutting the bark and 

 training the shoots, almost 

 any variety of design may 

 be produced. 



After two or three years 

 the crop of umbrella han- 

 dles and walking sticks is 

 harvested and after the 

 necessary treatment, the 

 product is ready 

 for the market. 

 If you feel 

 that the raising 

 of beans and po- 

 tatoes is too 

 prosaic, try the 

 artistic cultiva- 

 tion of original 

 designs in um- 

 brellas and canes.
