The Rafters
or roof-rods, should extend a foot each way beyond the cabin, hence cut them two feet longer than the cabin, and after testing your uprights, to see that they are exactly plumb, nail the two side roof-rods in place (see dotted lines in [Fig. 222]). The cross-pieces at the ends, as they support no great weight, may be fitted between the two side-rods, and nailed there.

The roof is to be made of ½-inch boards bent into a curve, and the ridge-pole, or centre roof-rod, must needs have some support. This is obtained by two short pieces of 2 by 4, each 6 inches long, which are toe-nailed to the centre of each cross-rod, and the ridge-pole nailed to their tops. At 3 feet from the upper deck the side frame-pieces are toe-nailed to the uprights. As may be seen, there are three two-by-fours on each side ([Fig. 222]).
The space between the side frame-pieces, the two middle uprights, and side roof-rods, is where the windows are to be placed.
Use ½-inch (tongue and groove preferred) pine boards for sidings, and
