some extent, ixsed as lumber. It was, however, observed on the sum- 

 mit between the Coldwater and Coquihalla Elvers (3,280 feet) ; also 

 on the Nicolume, a few miles beyond the summit, between that stream 

 and the Sumallow, and on the west side of the Spioos, near the trail 

 crossing. It was noted (doubtfully) on the summit between the forks 

 of the Skeena and Babine Lake. (Dawson.)

Yery abundant on cold soils in many parts of Nova Scotia and 'Sew 

 Brunswick, and throughout Quebec and Ontario. It is everywhere a 

 fine large- tree, and would be more valued were pine not so plentiful. 

 (Mdcoun.) Its northern limit crosses the St. Lawrence a little below 

 Quebec, and passes thence to the north end of Lake Temiscamang, 

 on the Ottawa Eiver, and from there to the eastern extremity of Lake 

 Superior at Agawa, south of Michipicoten Eiver. (iS. Bell.)

On the line of the Canadian Pacific Eailway, this tree was noticed 

 furthest east in the valley of the Columbia, at Donald, but it is, no 

 doubt, abundant on the mountain slopes about 1,000 feet above the 

 river. Pew of these trees are noticed along Beaver Creek valley, on 

 the line of the road, until Stony Creek is reached, at an altitude of 

 3,500 feet. Thence to the Selkirk summit scarcely any other tree 

 is seen, and ascending the mountain side above this line, anywhere 

 along Beaver Creek, it is always met with. In the Selkirk Mountains 

 it is a tall, beautiful tree, over 150 feet high and often very large. 

 (Macoun.) The hemlock occurs everywhere in the vicinity of the 

 coast of British Columbia, and extends up the valley of the Eraser and 

 other rivers to the limit of the region of abundant rainfall. It re-ap- 

 pears in the Selkirk and Gold ranges, where sufficient moisture for its 

 growth is again found. The tree attains a large size on the coast, 

 reaching a height of 200 feet, and yields a good wood, but has not yet
