Nesting boxes should not he nailed to trees, as after the birds have left them they serve as hiding places for gypsy moths and receptacles for moths' eggs; also if nails are driven into a tree they may in time be overgrown by the wood and become dangerous obstacles for axe or saw when the tree is cut up. The hollow of the limb fio- 2- — HoUow should not be less than 3j to 4 inches in diameter at the bottom, and 6 to 8 inches in depth below the entrance. The deeper the box, the longer the overhang of the roof, and the higher the hole the less chance there will be for cats and the other large enemies of birds to reach the eggs or young. Perches are not necessary. Some birds like them, but they give the enemies of the birds the advantage of a better Log Nesting Box. Ernest Thompson Seton recommends the following plan: — A nesting box may be made of a stick of wood or a section of a small log by first splitting off four slabs with an axe and then nailing in at each end a section sawed from the core that is left after the slabs are split off. A hole may be bored for an entrance for the birds. (See diagram. Fig. 3.) This box may be quickly made of wdiite pine, chestnut or cedar. A sec-.
