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 m that 
city. _ 
Note. — The Florida Nighthawk (C virginianus chap- 
mani), a smaller race, has been discovered breeding at Tarpon 
Springs, Florida.
