This contraction is easily made by driv- ing the tube into a coni- cal hole drilled in a piece of iron. Just below the blast-pipe chisel out a piece TTyiii- deep to admit a strip of wii'e gauze, which is to be placed there to prevent the possibility of any dirt or ash from the smoker getting accident- ally into the bellows. The piece S can now be glued on the Ijoard, Fig. 4, in the position shown by the dotted lines, it being on the underside in the illustration. To prevent its being.

Glue the strips R on each of the boards, with the thickest edges towards the hinge, and the piece T fin. away from R, Fig. 4. Secure all these pieces with a couple of nails each, but do not allow the points of the nails to go through the boards, and thus disfigure them. The piece of wood V, Fig. 4, is SAin. long by T^^in. square. The two ends are rounded, so as to allow them to fit tightly into the holes of the spirals in the spring. A piece of No. 22 wire is inserted through the holes, and lays along the side of the wood, and when the springs are in the position seen in Fig. 4 the ends of the wire i"ig. 8. are turned up, and prevent the springs from slipping off. The boards are now ready to put together, and to have the hinge put on. This is a strip of leather oin. long and l^in. wide. Lay the two boards. Figs. 4 and 5, so tliat the strips R face each other. Then glue the ends, and i^ut on the leather.
