Fig. 139. Two family house and tenement

The side view shows a simple shelf made of a back piece secured to the side of the barn by screws or nails, a plain shelf nailed to this back piece, and two wooden brackets. If iron brackets are used, both the shelf and back piece may be omitted, the brackets being fastened to the under side of the bird house and to the siding of the barn by screws.

For birds like the high-hole, or flicker, a piece of hollow log, or an elongated box fastened securely to the side of a pole, made cat proof, is very acceptable. This should not be painted, but should be provided with a door on the side and a perch. ([Fig. 137].) The opening should be about three inches for these large birds, and the location should be as secluded as possible. Any number of devices will suggest themselves, but always remember the cat, and study the location from the bird point of view. The martins and swallows are especially to be encouraged, as they are wonderful destroyers of insects.

Fig. 140. The bird bath

One device, especially grateful to these feathered friends in hot weather, is a pan of water, in a place where they can drink and bathe without being eternally on the watch for that crouching enemy, who is always stalking them—Tabby.

A pedestal with a platform about four feet above the ground will do nicely, and it can be placed so close to the house that you can watch them, and enjoy their ablutions almost as much as they do. ([Fig. 140].)

The construction is too simple to require an explanation.
