the Coast Range. {Lord.) Common everywhere; breeds. {Streator.) 

 An abundant summer resident at Chilliwack, Fraser River valley, 

 B.C. {Broaks.) Uniformly abundant throughout British Columbia 

 up to 5,000 feet. {R/toads.) Immense flocks late in the fall at Lulu 

 Island in the lower Fraser River, B.C. {E. F. G. White.) 



In the Northwest Territories, where the habitations of men are 

 few and far between, it inhabits caves; particularly in the lime- 

 stone rocks, and it also frequents the outhouses of the trading 

 posts. When Fort Franklin was erected on the shores of Great 

 Bear Lake, in the autumn of 1825, we found many nests in the 

 ruins of a house that had been abandoned for more than ten years. 

 At Fort Chipweyan in Lat. 59° the barn swallows arrive regularly 

 about May 15th, and we observed them in the same month at 

 Fort Good Hope, on the Mackenzie River, in Lat. 67^^°. 

 {Richardson.) North to Fort Resolution on Great Slave Lake; 

 rare. {Ross.) A few barn swallows were always found about the 

 numerous deserted Indian villages and their nests were frequently 

 noticed bn the big cedar beams which are the framework of the 

 Haida houses on Queen Charlotte Islands. {Osgood) This bird 

 is the most common and widely distributed species of the swal- 

 lows throughout the north. In Alaska it is found along the south- 

 eastern coast, extending thence over nearly the entire Aleutian 

 thain, and north along the coast of the mainland to Kotzebue 

 Sound, and thence east throughout the territory wherever suit- 

 able locations occur. {Nelson.) Breeding abundantly about the 

 town of Sitka, Alaska, under the eaves of buildings; a few pairs 

 found nesting on the qliffs on the islands out in the bay. This 

 swallow was seen almost daily at Cape Blossom, Kotzebue Sound, 

 Alaska; the species was seen on the upper Kowak and in the 

 delta of that river in June. {Grinnell) This bird arrives at 

 St. Michael about June and as soon as the ground is thawed begins 

 to build. {Turner.) 



Breeding Notes. — The nest of this species" is built of mud 

 mixed with hay or straw and lined with fine grass and a thick bed 

 of feathers. Eggs 5, white, spotted with reddish-brown. {G.R. 

 White.) Not nearly so plentiful at Scotch Lake as lunifrons. 

 Always building inside buildings. Eggs, from 4 to 6, placed in a 

 soft feather-lined nest of mud and hay. Some pairs raise two 

 broods in one season in the same nest. One pair abandoned the
