This troo extends tVom Halitii.x, in Nova Scotia, north-westorly to the 

 Athabasia River, near old Fort Assiniboino, and northerly down the 

 Mackenzie Kiver to llie arctic circle. In the east it scarcely foi'ms a 

 tree, but on the Ottawa, at Potowawa and Chalk Eivor, it is one of 

 some size. North of Lake Superior, it forms groves of tall trees, 

 which become taller and tiner on the J)awson Ifouto; westward of 

 Lake Winnipe:; and ncn-th of the Saskatchewan, it equals the red 

 j)ine of the east in heii^ht and diameter. It ie so well-grown on 

 the Clearwater Uiver, noifh of Mcthy Portage, tliat Sir John 

 Kiehardson confounded it with P. resinosa in his list of trees and shrubs 

 of British America. (^Macotin.) Starting fi-om the head of the Bay of 

 Chaleurs. its northern limit seems to be Lake Mistassini, from which 

 it runs west to the Moose Eiver, keeping about 100 miles south of 

 James Bay. It does not touch cither James or Hudson Bay. (E. Hell.) 

 Abundant, though of small size, in most of the country around Lake 

 Mistassini and down the Ruj^ert River as far as Lake Nemiskow. (J. 

 M. Macoun.') Two trees only have been observed near Ottawa, one 

 found on King's Mountain, Chelsea, P.Q., by Mrs. J. G. Bourinot, and 

 one near the Mer Bleue at Eastman's Springs. {Fletcher.)

This tree is abundant in Newfoundland and in every part of Canada, 

 except southern Ontario and the prairie region. It climbs highest on 

 the Shickshocks, in Gasp6, and creeps the closest of any of our conifers 

 to the cold waters of the Labrador coast and Arctic Sea. At its north- 

 ern and southern limit it nearly loses its tree form, becoming in the 

 north a bush, while in the south, in the deep swamps, it is little larger 

 than a hop-pole. From Lake Winnipeg, westward, it becomes a mag- 

 nificent tree, averaging from two to three feet in diameter and rising 

 to a height of eighty feet. North of the Saskatchewan and south of 

 Lakes Manitoba and "Winnipcgoosis, it covers large areas, while in the 

 Beaver and Athabasca valleys it is even larger, and descends the latter
