the Coast Range. (Lord.) Common everywhere; breeds. (Stveator.) 
An abundant summer resident at Chilliwack, Fraser River valley, 
B.C. (Brooks.) Uniformly abundant throughout British Columbia 
up to 5,000 feet. (Ahoads.) Immense flocks late in the fall at Lulu 
Island in the lower.Fraser River, B.C. (4. &. 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 ahouse 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 on 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 
chain, and north along the coast of the mainland to Kotzebue 
Sound, and thence east throughout the territory wherever suit- 
able locations occur. (Ve/son.) Breeding abundantly about the 
town of Sitka, Alaska, under the eaves of buildings; a few pairs 
found nesting on the cliffs 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. (Gvinnell.) This bird arrives at 
St. Michael about June and as soon as the ground 1s thawed begins 
to build. (Zurner.) 
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. 2. 
White.) Not nearly so plentiful at Scotch Lake as /unifrons. 
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
