Sept. 6. 
Chordeiles popetue. 
Middlesex County, Mass. 
One was seen in the gamps by Deane on the 19th. 
I saw a company of six or seven flying south over Fresh 
Pond. 
A number passing south this evening I have seen 
them flying nearly every evening since August 26. Ordi- 
narily they pass rather high in air, keeping along pretty 
steadily, but after it begins to get dark they fly lower 
and I ha/e seen several gliding silent and ghostlike 
through the gardens and streets in the city keeping close 
to the ground. 
11. 
Saw one this evening.
