dreds together, and darting after insects or feeding leisurely as 

 they advance towards more congenial climes. For two or 

 three weeks these processions along the rivers and their banks, 

 tending towards their destination, are still contmued. Mingled 

 with the wandering host are sometimes also seen the different 

 species of Swallow, — a family to which they are so much allied 

 in habits and character; but by the 20th of September the 

 whole busy troop have disappeared for the season. 



I have observed Nighthawks flying over the city of St. John, in 

 New Brunswick, during most of the summer months, and have 

 known of the eggs being found frequently on gravel roofs in that 

 city. 



Note. — The Florida Nighthawk (C virginiamis chap- 

 mani), a smaller race, has been discovered breeding at Tarpon 

 Springs, Florida.
