TREE SWALLOW! Nesting-box should have the following inside dimen- 

 sions, floor, 5 by 5 inches; depth, 7 inches; entrance, \\/2 inches in 

 diameter, with its lower edge 4 inches above the floor. It may be 

 mounted upon a pole, and the pole may then be screwed or bolted to 

 a post in the fence inclosing the garden, orchard, or mowing land. 

 When fastened to the trunk of a tree, be sure that one is chosen whose 

 branches are high enough above the nesting-box to allow the birds free- 

 dom of access to their home, after the foliage has fully matured. The 

 nesting-box should be placed at a height of from 8 to 15 feet above the 

 ground. 



CHICKADEE: Nesting-box should have the following inside dimensions, 

 floor, 4 by 4 inches; depth, 10 inches; entrance, \V^ inches in diameter, 

 with its lower edge 7 inches above the floor. It should be placed at a 

 height of from 6 to 12 feet above the ground, and may be mounted on 

 a pole placed in the orchard, or open woods, or fastened to the trunk 

 of a tree. All nesting-boxes for the Chickadee should be situated in 

 open spots, and not in the dense forest. Possibly a nesting-box painted 

 a dull white, simulating the color of a gray birch stub, would be 

 more readily occupied by the Chickadee, than one stained a shade of 

 brown or olive green. This is a suggestion of the author, and might be 

 worth trying, from the fact that the Chickadee when excavating its home 

 in a dead tree prefers the gray birch, the decayed wood of which is 

 easily removed by the tiny builder. 



WHITE-BREASTED NUTHATCH : Nesting-box should have the following 

 inside dimensions, floor, 4 by 4 inches; depth, 10 inches; entrance, 

 \V\ inches in diameter, with its lower edge 7 inches above the floor. 

 It should be placed at a height of from 10 to 20 feet from the ground, 

 on the trunk of a tree in open woods or in the orchard. 



HOUSE WREN: Nesting-box should have the following inside dimen- 

 sions, floor, 4 by 4 inches; depth, 8 inches; entrance, 1 inch in di- 

 ameter, with its lower edge 6 inches above the floor. It may be fastened 

 to the side of an outbuilding; to a tree in the orchard; or, mounted on 

 a pole. In any of these situations, the height above the ground should 

 be from 6 to 10 feet. 



FLICKER: Nesting-box should have the following inside dimensions, 

 floor, 6 by 6 inches; depth, 18 inches; entrance, 2^ inches in diam- 

 eter, with its lower edge 14 inches above the floor. It should be fastened 

 to a tree standing in the open, or a pole and at a height of from 8 to 20 

 feet above the ground. Trees bordering country highways, or near the 

 edges of open fields should be selected for this purpose. 



RED-HEADED WOODPECKER: Nesting-box should have the following 

 inside dimensions, floor, 6 by 6 inches; depth, 16 inches; entrance, 

 2 inches in diameter, with its lower edge 12 inches above the floor. It
