On the base or bottom of the form under 
construction lay out, with a pencil, a 
rectangle 38 inches long and 18 inches 
wide, being very careful to measure accu- 
rately and make a true rectangle. Then, 
with 3-inch screws, fasten the side pieces 
to the base, keeping them outside the 
rectangle but precise on the pencil line. 
Use three screws to each side. Next fit 
the two end pieces between the sides— 
outside the rectangle, 
the pencil lines—and fasten each with 
two screws. You now have

(made of No. 14 wire, mesh 1 inch) and 
fasten with wire onto the iron rod frame, 
which it should just cover. Cut eight 
pieces of the iron rod, 18 inches long, and 
lay across the wire cloth at intervals of 
four inches. Across these lay, length-
