Above, Cross Section of Mould or Form for Cement Base at XâX, with Frame Stayed with Wire. Below, Ground Plan of Mould, with Reinforcing in Position. pieces 2 by 2 by i8 inches for the ends. 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 lit the two end pieces between the sidesâ outside the rectangle, but precisely on the pencil linesâand fasten each with tv.o screws. You now have a shallow box 18 by 38 inches, inside measure- ments. The form is complete unless you wish to break a ^ or ^,-inch quarter- round moulding around the top inner edge of the ends and side pieces. This gives a certain finish to the base similar to a bevel edge. Reinforcing the cement base, which is necessary, is accomplished as follows: Take a piece of iron or steel rod, 9 feet long, and bend it into a rectangle of such a size that it will drop loosely into the form. Then cut a piece of wire cloth (made of No. 14 wire, mesh i 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- wise of frame, three pieces 35^^ inches
