PREFACE. Vv 
Spreadborough. His notes, revised by us, cover nearly the whole 
Dominion from Labrador and Hudson bay to Vancouver island and 
north to the Peace river. A more detailed statement of the work done 
in each year will give a better idea of the extent of country covered. 
In 1889 Mr. Spreadborough was with the authors for two months 
at Hastings and Agassiz on the lower Fraser river; the remainder 
of the season was spent between Spence Bridge and the Columbia 
river. The next season he began work at Revelstoke, on the 
Columbia and spent the summer in the mountains south and east. 
The spring of 1891 found him at Banff in the Rocky mountains 
before the birds began to move, and he remained there all summer. 
As Mr. E. T. Seton (then E. Seton-Thompson) had already covered 
Manitoba with his excellent work, it was considered best for Mr. 
Spreadborough in the following year to visit Indian Head in the 
prairie country to the west of that province noting all the migrants, 
as.in previous years, and obtaining skins and recording the summer 
birds of that district. In the spring of 1893 he began work on 
Vancouver island and made collections during the whole season: 
In 1894 the district around Medicine Hat, Alta., and eastward to 
Crane lake, Sask., was examined and in 1895 the prairie region 
south of the Canadian Pacific Railway. Im all these years Mr. 
Spreadborough worked under the direction of the writer. The 
summer of 1896 was spent by him on Hudson bay and across Ungava 
and in 1897 and 1898 he was in the Rocky mountains, in the former 
year working with the writer south to Crow Nest Pass, in the latter 
independently in the Yellow Head Pass. In 1goo, again with the 
writer, the collecting season was spent in Algonquin Park, Ont. 
During 1901, 1902, 1903 and 1905, Mr. Spreadborough was with 
Mr. J. M. Macoun; 1901 was spent in the Coast Range, B.C., chiefly 
around Chilliwack lake ; 1902 between Trail and Cascade on the 
International Boundary; 1903 in the Peace River region and 1905 
again on the International Boundary between Cascade and Chilli- 
wack lake, thus compieting a traverse of the whole region between 
the Columbia and the western slope of the Coast Range; the country 
between Chilliwack Lake and Douglas on the Coast was examined 
in 1906. The year 1904 was, perhaps, the most important of any, 
as the early spring was spent by Mr. Spreadborough in the vicinity 
of Fernie and Elko, B.C., thus connecting the work of 1897 with 
that of 1902, and the early summer and autumn months on the 
south and west coasts of Hudson bay where he studied the habits
