parts of the Saskatchawan River are also used by this bird for nesting-places." To the 

 northward, in Alaska, Mr. Dall found the Cliff-Swallow, and he observes : — " This is the 

 most common species at Nulato, where the eaves of the fort, inside and out, are lined 

 with their clay-domes. It is also found at Port Yukon, and the Redoubt, St. Michael's. 

 The Indians say that before the forts were built this bird made its nest on the face of 

 some sandstone cliff under some projecting fragment. H. horreorum frequently builds 

 on the Indian caches, but I have never known this species to do so." 



Mr. E. W. Nelson writes: — "The lack of proper surroundings on the coast of 

 Alaska and the Arctic Ocean appears to limit the range of this bird to the interior, and 

 although I kept a continual look-out for it during my residence in the north, I did not 

 see a single individual. At Nulato, Dall records its arrival from May 10th to 16th, and 

 from these dates up to the 21th. At the same place he found it nesting commonly 

 about the trading stations, and was told by the natives that it nested on the faces of the 

 sandstone cliffs along the Yukon, before the advent of the white man placed at its 

 disposal the convenient shelter of the trading posts. The birds were quick to take 

 advantage of the hospitality offered them, and to change from their primitive nesting- 

 sites to civilized domiciles. 



"It is also found breeding at Tort Yukon. Mr. Dall records the presence of this 

 bird at St. Michael's, but not one was seen during the four years passed by me at that 

 place, and the evidence seems to point to a mistaken identification, whereby the common 

 Barn-Swallow (which is very common there) was mistaken for the present bird. These 

 Swallows are recorded from Point Lake, latitude Go , in British North America, and in 

 Alaska they are known to extend north of the Arctic Circle. Its extension north to the 

 Arctic Ocean is doubtful — at least in our territory — owing to the low and unsuitable 

 nature of the country, in addition to the harsh and repelling climate. There is a single 

 specimen in the National Museum Collection, obtained by Kennicott at Port Resolution, 

 June 23, and this and the points previously given constitute the northernmost limits of 

 its range. There is no evidence of its presence in the south-eastern part of the 

 Territory." 



Mr. Agersborg states that it is common iu South-eastern Dakota, and breeds ; and 

 the following note is given by Dr. Coues in his paper on the Birds of Dakota and 

 Montana : — 



" This is the most abundant, generally distributed, and characteristic species of tin; 

 family throughout the region under consideration. The various streams that cut their 

 devious ways through the prairie afford an endless succession of steep banks exactly 

 suited to its wants during the nesting-season, and at various places great clusters of the 

 curious bottle-nosed mud-nests were found, while the flocks of Swallows which often 

 hung about our camps were mainly composed of this species. At some points, the Bank- 

 Swallows were breeding with them; the same banks being peppered with their little 

 round holes, generally in the soft soil just below the surface, while the projecting nests 

 of the Cliff- Swallows studded the harder or rocky exposures below. At Tort Pembina
