The Bank Swallow 



Perhaps you have seen a sand bank somewhere, prob- 

 ably near a river or pond, where the side of the bank was 

 filled with holes as if a small cannon had been trained 

 against it as a target. In and out of the holes fly the

 friends. Year after year a colony wiU return to a favorite 

 bank, whose face has been honeycombed with such care. 

 Think of the labor and patience required for so small a bird 

 to dig a tunnel two feet deep, more or less, and enlarged at 

 the far end! Some nests have been placed as far as four 

 feet from the entrance. One is not surprised at the big 

 kingfisher, who also tunnels a hole in a bank for his family, 

 because his long, strong bill makes digging comparatively 

 easy; but for the small, weak-footed swallow, the perform-

 have; certainly countless numbers assemble every year in 

 the Long Island and Jersey marshes, and perch on iJie tele-
