 Fort Colville. 



In June I observed a very large number of 

 swifts in company with about an equal num-

 within shot ; neither did I ever after see them. 

 On opening the goatsucker, its stomach was 

 perfectly gorged with winged ants. I have no

 swifts on their northern route; and from the 

 fact of their disappearing here, as they did at 

 Sumass, I imagine they go far north to nest; 

 had they bred anywhere along the Boundary- 

 line, I am sure I must have discovered them. 



White-bellied Swallows (Hirundo bicolor} are 

 always in great force, and make their nests of 

 ducks' feathers, in holes either bored by them- 

 selves, or the work of woodpeckers, in the totter-

 grounds, and commence domestic duties.
