The "trowel" (Fig. 1339) should measure about 12 in. long, 4 in. wide, the blade being of light good steel, and the handle well rounded. The "hawk" (Fig. 1340) has a blade of hard wood, 14 in. sq., 3/4 in. thick in the middle and reducing to 1/4 in. at the edges, with a cleat in the back to resist warping; the wooden handle is barely 6 in. long and under 1 1/2 in. thick. The "float" (Fig. 1341) is a hard board about 12 in. by 4 in. and § in. thick, with a cleat let into the back to which the handle (bentwood) is attached. The " darby " (Fig. 1342) is a pine board 4 ft. long and 4 in. wide, with a handle like that of the hawk near one end, and a narrow flat strip near the other. The "scratcher" (Fig. 1343) consists of a few short strips of wood, pointed at the end, and secured to cross-pieces at about 1 in. apart. In addition there are required a straightedge, a long plumb level, an angle block for corners, a whitewash brush, a pointing trowel, a paddle for finishing angles, mitreing tools and moulds, and light scaffolding.
