After the sides and ends are put together, get out two boards, of the shape shown in Fig. 373, to rest in four rectangular notches cut in the front and back sides of the house. These pieces are to support the roof-boards, and their upper edges are to be cut at the same angle as the top of either end of the house. Nail these pieces firmly in place at each end (Fig. 374).
Fig. 374.
Now get out boards for the roof, to run from end to end and about 4" longer than the house. Begin to nail them on at the top, and have the roof overhang the sides and ends 2" all around.
You can easily put in the window-sash, either by hinging it so as to swing open, or by having it slide to the right or left on strips nailed above and below it, as shown in Fig. 369.
The roof-boards can also be laid the other way by putting in a ridge-piece in the form of a piece of studding or joist of any size not less than 2" × 2" (Fig. 377), or even a board on edge, to which the upper ends of the roof-boards can be nailed.
Fig. 375.
Another form of roof, but arranged in the same way, is shown in Fig. 375.
You will require a compass-saw for the curves, or you can have them sawed by a band-saw, or the wood can be trimmed to the line with the hatchet and draw-knife or chisel (see Paring).
