common and widely distributed species of the swallows throughout 

 the north. In Alaska it is found along the southeastern coast, ex- 

 tending 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 suitable locations occur. (Nelson.) 

 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 Jtme. (Grinnell.) This 

 bird arrives at St. Michael about June, and as soon as the ground ig 

 thawed, begins to build. (Turner.) 



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

 with hay or straw and Uned with fine grass and a thick bed of feathers. 

 Eggs, five; white, spotted with reddish-brown. (G. R. White.) Not 

 nearly so plentiful at Scotch Lake as lunifrons. Always building 

 inside buildings. Eggs, from four to six, 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 second brood and 

 went south, September 9th, 1901 ; the young died in the nest. (W. 

 H. Moore.) I was told by missionaries that the swallows nested in 

 the deserted Eskimo igloos, building their mud nests against the sides , 

 near the roof. On July ist, 1899, I found a bam swallow's nest 

 built on a beam in the house of a small river steamer, stranded at the 

 side of Mission inlet. The nest was constructed as usual of a mix- 

 ture of mud and grasses with a lining of finer grass and a large quan- 

 tity of white ptarmigan feathers almost burying the eggs. (Grin- 

 nell.) Nests oblong and attached to the walls or to the rafters of 

 barns and other buildings ; or round and placed on the beams. They 

 are made of mud arranged in small pellets formed and mixed with 

 grass and have a Uning of feathers and hair. Four to six eggs in 

 the set at Ottawa and at Lake Nominingue, 100 miles north of it, 

 in June and July. (Garneau.)

A few bam swallows were flying over the marshes of Chilcat inlet, 

 June ist, 1899; I heard they were common at White Pass City, June
