1893. Swifts appear to be more numerous this season than they 
June July 1. were last year. I hear them rumbling in the chimney of the 
Johnson's house making a sound like distant thunder or the 
rapid beat of horses' hoofs mingled with the roll of wheels 
across a wooden bridge. Another pair, nesting in one of the 
chimney Vs of Mr. Keyes's farm house, evidently have young as 
one or both of the old birds go into and from the chimney at 
short, regular intervals. Both of these chimneys are of the 
modern type with small flues. It is a pretty sight to see the 
I 
Swifts drop into them with fluttering wings.
