332 NOTES ON NEW ENGLAND BIRDS 



BANK SWALLOW 



May 23, 1854. Saw in Dakin's land, near the road, 

 at the bend of the river, fifty-nine bank swallows' holes 

 in a small upright bank within a space of twenty by 

 one and a half feet (in the middle), part above and 

 part below the sand-line. This would give over a hun-

 within scratching out the sand, — I see it cast out of 

 the holes behind them, — others hanging on to the en-

 swallows. They are white-bellied, dark winged and 

 tailed, with a crescent of white [s^c] nearly around the 

 lower part of the neck, and mouse-colored heads and 

 backs. The upper and greater part of this bank is a 

 coarse sliding gravel, and they build only in the per-
