flight iu ceaseless circles, gutlioring their evening repast, ho will not grudgingly 

 endure the little annoyance which they may occasion in his chimney. 



Observation. — The chimney swallows incline to be gregarious, especially iu 

 their roosting places. Audubon tells of a hollow tree in which he estimated 

 that over nine thousand had collected, and were in the habit of collecting 

 nightly to roost. An old chimney in a neighboring county was found, on one 

 occasion, to contain a still larger number ; and a very few years since there were 

 eome four thousand of them taken from a chimney (which had been unused) 

 of one of my neighbors.
