The flexible ball is constructed in the following man» 
ner : 
Take an ash or deal staff of the required length, and 
the substance of a stout pike. Take twelve whalebones, 
four feet six inches long, and fix them at nine inches from 
the top of the staff, in the way the whalebones of um- 
brellas are fixed fix the lower ends of these whale- 
bones to a strong slide (like the slide of an umbrella), 
the pipe of which must be 18 inches long, and project 
upwards. To the top of this pipe, stretchers 18 inches 
long must be affixed, and also to the middle of each 
whalebone, like the stretchers of an umbrella, to keep 
the ball stiff when in use. There must then be a strong 
umbrella-spring fixed on the staff, at three feet from the 
upper fastenings of the whale-bones, or top of the ball, 
so that, when the slide is pushed up, the whale-bones 
will form a sphere of three feet diameter.
