The roof is what is known as

The Gambrel or Octagonal Roof, and consists of two eight and two nine inch boards thirty-four inches long. Before fastening these in place, it will be necessary to make

The Gable-ends, which are cut out as shown in [Fig. 77]. Make the partition between the nursery and ball-room (H) in the same way, with a door cut in it, as shown in [Fig. 70].

Fasten the partition and gable-ends in place, after which nail the roof boards B and C ([Fig. 70]) to the top, allowing them to project over each gable. The lower boards A and D should be hinged to these, so they may be raised to get at the upper story. The edges of the boards must be bevelled in order to make perfect joints.

When the work has proceeded thus far, cut

The Door and Window Openings in the places indicated upon the [plans] and [Fig. 64], first boring holes in the four corners of each window and door space; and then connecting them with a compass-saw. With the exception of the front and rear door, and the windows in the basement and gable-ends, make all openings three by five inches, and two inches above the floor. The casement window openings in the gable-ends are to be four by five inches and extend to the floor. Cut three-by-seven-inch openings for the doors, and make the basement window openings two by three inches.
