THE BANK SWALLOW. 279 



looking hole about eight feet up prompted instant attack. A hand was about 

 to enter the coveted approach, when crack! went the stump, and down went 

 the small boy with the stub on top of him. But the mud was as soft as a 

 feather-bed and my first thought was for the eggs. There they were, four 

 delicate pink beauties, spilled out upon the black mud, but unbroken. The 

 nest cavity was filled within three or four inches of the entrance with chicken 

 feathers, and the sides were lined with them to the very edge of the hole. 

 Taking the least possible toll, one egg, I carefully replaced the others, then 

 dragged the stub several rods to an old fence, where I bound it fast with 

 wire to an upright post. The parent birds accepted the proffered amends; 

 the set was completed, and a handsome brood raised. 



In many localities Tree Swallows are prompt tenants of bird houses. 

 This does not seem to be largely their habit in Ohio; doubtless because suit- 

 able nesting sites in trees are still abundant. A pair once built their nest in 

 a sort of tower attic, just inside of a hole which a Flicker had pierced in the 

 ceiling of an open belfry of a country church. When in service the mouth 

 of the swinging bell came within two feet of the brooding bird. One would 

 think that the Swallows would have been crazed with fright to find them- 

 selves in the midst of such a tumult of sound ; but their enterprise fared suc- 

 cussfully, as I can testify, for at the proper time I saw the youngsters ranged 

 in a happy, twittering row along the upper rim of the bell-wheel.
