PROVIDE NESTING BOXES 37 
the bottom board projecting a few inches and forming 
a platform. 
2. Nuthatches and Creepers. — Inside measure of box 
about 20 x 6 x 6, place it on trees from 12 to 25 feet 
above the ground, rough inside and outside, no perch on 
the outside, entrance from 14 to 2 inches in diameter. 
3. Woodpeckers. —Quite a few of these birds are 
likely to avail themselves of nesting boxes, if made of 
hollow trunks and limbs or of wood with the natural 
bark on it. The boxes may be from 10 x 5 x 5 to 
36 x T x 7 inside measure, the entrance from 2 to 4 
inches in diameter. Place the boxes on trees from 10 
to 25 feet high, supply no perches and no thorns. I 
have found the flicker’s nest 4 feet from the ground 
in an old cottonwood tree, in a cavity only about a foot 
deep ; and with an entrance large enough for any man’s 
fist. This nest was in a prairie grove, where the cotton- 
wood was the only hollow tree. A pair of red-headed 
woodpeckers once built their nest in a telegraph pole 
on a much-frequented street in St. Paul, Minn. The 
children from one of the public schools passed there 
every day. Some boys climbed to the entrance repeat- 
edly, but the nest was too deep to be reached, and in 
due time the young appeared on the neighboring house- 
tops. The best way to attract woodpeckers is to spare 
old and hollow trees. 
4. Bluebirds. — Boxes of about 10 x 6 x 6 inside 
measure, fastened to trees or posts near shrubs and 
brush, from 6 to 15 feet above the ground, entrance 
from 2 to 24 inches in diameter. Mr. J. W. Taylor of
