154 Canadian Record of Science. 



Brewster and Lawrence are gentlemen of large fortune, 

 who study the science for occupation, and for the love of 

 it, and stand high as scientists. Lawrence helped Baird with 

 his greatest ornithological work, published in 1859. 



One of the investigations being conducted by the Union 

 is that of Bird migration and the geographical distribution 

 of North American Birds, and during the first year of its 

 existence, it received communications from more than a 

 thousand observers. The area over which these observers 

 are scattered is co-extensive with the boundaries of the 

 inhabited portions of the North American continent, and 

 includes parts of the West Indies, and Central and South 

 America. 



Stations now exist in every state in the Union, and in 

 every Territory excepting Nevada. The extreme points 

 from which reports have actually been received will appear 

 from the following : in the east, the southernmost station 

 is Sombrero Key, off Southern Florida (Lat. 24°3*7') ; and 

 the most northern, Belle Isle off Labrador (Lat. 51°53'), 

 whilst from the west, reports have been received from 

 Arizona and Southern California, as well as from Point 

 Barrow, the most northerly point of Arctic Alaska (Lat. 

 11° 18'). The most eastern station from which data have 

 been obtained, is St. John's Newfoundland (West Long. 

 52°45') projecting well into the Atlantic ; while on the 

 Pacific, the committee has observers at various points in 

 California, Oregon, Washington and British Columbia. 



Hence it appears that the migration stations are sprinkled 

 over 46°41' of latitude (approximately three thousand two 

 hundred miles in a north and south direction) and 72° 15' 

 of longtitude (approximately three thousand five hundred 

 miles in an east and west direction.) The distance in a 

 straight line between the two. most remote points (Sombrero 

 Key and Point Barrow) is about four thousand three hund- 

 red miles. This territory is divided into sixteen districts, 

 each under the immediate direction of a competent 

 superintendent. In Canada there are stations with the 

 following superintendents : — North West Territories : Ernest 

 E. T. Seton, Assiniboia, via Carbery, Manitoba; British
