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 1st; not 
rare up the Clearwater river to Methye portage; a few birds on 
Deep river near Isle a la Crosse. (J. 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, du1ing 
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
