near West Chester (Chester county.) At that time they liad constructed about four or 

 five nests. Yesterday, June 13, t again visited the locality, and after searching about

 probably been sat on several days, but I secured them with the nest. * * * 

 I do not think there is more than a single pair in the locality, but it seems incredible that 

 they should make so manj'^ nests."
