For the back yard, or in the fields and woods near the house, a summer-house or pergola will be found a comfortable nook in which to spend many pleasant hours.

A simple summer-house is shown in the illustration, Fig. 1. This is made of four posts, has a shingled roof, and is provided with seats on three sides. Obtain four spruce posts four inches square, or four tree-trunks from four to six inches in diameter. Plant them in the ground, forming a square of six feet. The posts should be embedded for at least two feet, and, to insure them from decaying too quickly, tar or pitch the bottoms, or give them two or three good coats of asphaltum varnish. The posts should stand seven feet above ground. Across the tops of the posts nail two-by-four-inch joist, with lap joints as shown at A in Fig. 2. With four more pieces of joist form the roof rafters, cutting a notch in each joist where it fits over the corners at the head of the posts. At the peak, the joist are bevelled where they meet.

Join two of the pieces at first; then lap the remaining two on both sides of them, nailing all the ends securely with steel wire nails. Put one middle rafter in on each side between eaves to the roof. It would not look well to have to roof the corner ones; then nail shingle lath or scantling on the four sides to receive the shingles. The rafters should overhang the top frame about twelve inches, so as to form the stop on a line with the posts. Begin at the bottom and at the middle of each side to shingle the roof, working out to the corners and up through the middle to the peak. To prevent the roof leaking at the corners, bevel the shingles at one side, then lap those on the other side over them and bevel the edges. Some builders lay a strip of tin flashing over the edges as well as in the valleys of a roof to insure a perfectly water-tight joint. Use galvanized nails. To hide the rough rafters and shingle lath, the inside of the roof may be lined with narrow, matched boards; then the wood-work may be given a coat or two of paint in some desirable color.
