noticed at Old Wives creek, Sask., and afterwards on the prairie 

 wherever there were cut -banks to Frenchman river; it was also 

 seen on the prairie at the west end of the Cypress hills; later it 

 was found to be abundant along the Milk river, St. Mary river and 

 Lee creek, almost to the Rocky mountains ; first seen at Edmonton, 

 Alta., May 8th, 1897; breeding in the river bank below the lower 

 ferry by May 22nd; common from Lesser Slave lake to Peace River 

 Landing, lat. 56° 15', in June, 1903; breeding in the banks of Bragg 

 creek, about 40 miles southwest of Calgary, June 25th; breeding in 

 the cut banks of the Bow river, below Banff, in the Rocky moun- 

 tains, in June, 1891; abundant at Kamloops, B.C., 1889; a flock 

 was seen in the Eagle pass, 5 miles west of Revelstoke, May 13th, 

 1890, but none in the Columbia valley; breeding in numbers in the 

 bank of the Columbia just below Trail, B.C., in June, 1902; ob- 

 served first at Penticton, B.C., April 24th, 1903; they only stayed 

 a few days when they disappeared. (Spreadborough.) 



Very abundant on the Athabaska river between Lesser Slave 

 river and Fort McMurray, lat. 56° 40', first noticed June ist; not 

 rare up the Clearwater river to Methye portage; a few birds on 

 Deep river near Isle k la Crosse. (/. M. Macoun.) This species 

 is very widely distributed in the Northwest Territories and thou- 

 sands were observed fluttering at the mouths of their burrows near 

 the mouth of the Mackenzie river in lat. 68°, on July 4th; they 

 are equally numerous in all other localities suited for burrowing. 

 (Richardson.) North to Fort Simpson on the Mackenzie river; 

 abundant. (Ross.) Found in thousands along Great Slave river to 

 Fort Resolution. Not seen farther, northeasterly. (E. T. Seton.) 

 This species is to be met with in considerable numbers during the 

 season of nidification; it builds its nests in holes in sandy or clay 

 banks on Anderson river. (Macfarlane.) Scarce .at Chilliwack; 

 may breed in vicinity. (Brooks.) 



Along the arctic coast, as well as the shores of Behring sea, this 

 is an extremely rare visitant, occuring merely as a straggler, duiing 

 its migrations; on the river courses of the interior, however, it is 

 one of the most abundant, if not the most abundant species of 

 swallows. (Nelson.) These swallows are but occasional visitors 

 to the vicinity of St. Michael, where it was only observed during 

 the middle of the summer season. (Turner.) More plentiful
