 points to prevent them from sticking in the boards, 

 and give a little bend just near the coil (see Fig. 

 100). The ends of the piece of wood which have 

 been prepared, -~ in. square and 3^ in. long, are 

 rounded and passed through the coils of the 

 springs, and a little bit of thin wire ties them 

 together to prevent their slipping off. This axle, 

 as it may be called, of the springs is then placed 

 between the pieces x and Y (Fig. 95), and the

The valve is a piece of leather 3 in. by 2 in.,

 the valve is secured to the board with two tacks. 

 A light spring (shown in Fig. 95) presses very
