��In such case it is only necessary to fill the lower tank through the pipe having the screw-plug; then by turning the fountain up-side-down the water will run into the other tank. Place the fountain in its proper position and half fill the basin with water, which will rush down the pipe and set the fountain into action. It is not advisable to keep fish in the basin.

A simple garden fountain is shown in the illustration. The pressure tank of this fountain consists of a vertical cylinder about 10 in. high and 6 in. in diameter with a piston heavily weighted. A pipe is connected with a fountain basin having a center nozzle. To start this fountain re- move the piston and fill the cylinder with water. Replace the piston and the com- pressed water will force the fountain to act automatically. — John Y. Dunlop.

ing it with shingles, prepared roofing or the like, palm leaf fans were nailed on as if they were shingles. These were placed in horizontal rows parallel with the rafters. To construct such a shelter the following materials are required :

2 posts, 1 1 ft. long and about 6 or 8 in. in diameter. 7 pes. of 12-ft. stock 2 by 4 in. in size. 35 ft. of sheathing.

A quantity of palm leaf fans. The amount neces- sary depends on the size of the fans.

The two posts are set about 3 ft. in the ground and tamped in solidly after the

��upper ends have been cut sloping to fit the pitch of the roof. Two struts or joists are run through mortises cut in the posts 1 ft. 3 in. from their upper ends, or about 6 ft. 9 in. from the ground level. It is best to make this measure- ment from the upper ends so that the proper measurement will be secured. The other joists are fast- ened on the same level with pieces across their upper edges for a temporary support until the rafters are in place. The sheathing is firmly fastened with nails. The rafters are cut on what is called the half pitch roof, because the height at the center is half the distance of the width. At the top a ridge board is set in between the rafter ends. This board is fastened in place as the rafters are nailed.

The amount of sheathing given in the list is sufficient to allow a space between boards. This mode of construction can be used where a panel is to be set in on the underside of the joist. In case the panel is not used it is best to put on the sheathing without spaces, and with surfaces planed down to produce a finished effect. In the latter instance it will require more boards or about 45 sq. ft.

The panel shown in the illustration is another feature of this shelter. It is made of thin material such as is used in the ordinary market basket, and is woven to- gether in basket fashion or like a chair bottom of the old hickory kind. It is then cut into a rectangle as shown and fastened to the upper surfaces of panel boards, when the whole is fastened in place on the under- side of the joist with finishing nails.

After applying the palm fans in the same manner as shingles their upper courses on each side of the roof are finished with pre- pared roofing or ridge boards at the top. This gives a finished effect and covers up a large space that cannot be filled with the fans. The effect of the finished shelter is very artistic.
