acts as an excellent wind-break along the Bruce Peninsula; passing to 

 the west, it still continues abundant north of Lake Superior and at 

 least to Lake Winnipeg. (Macoun.) Collected on Nelson Eiver and 

 at York Factory. (B. Bell.) 



565. PINUS, Linn. (PINE.) 



(2072.) P. Strobus, Linn. White Pine. 



One of our most valuable and widely spread trees, extending from 

 Newfoundland, Anticosti, Nova Scotia and New Brunswick, through- 

 out Quebec and Ontario, and reaching nearly to Lake Winnipeg. Dr. 

 Bell places its eastern limit on the north shore of the St. Lawrence at 

 Mingan ; thence it passes westerly and northerly round the head 

 of Lake St. John, and, still keeping to the north, is found on the head 

 waters of the Moose Eiver. In the country north of Lake Superior it 

 is very scarce ; in fact, has no existence on the line of the Pacific 

 Eailway, and only a few trees occur on Nipigon Eiver. (Macoun.) 

 It is scattered over the country between Lake Superior and the Winni- 

 peg Eiver and around Lonely Lake, but is of rather small size. In 

 approaching Lake Winnipeg, the limiting line of the tree curves to the 

 south-westward, and crosses the Winnipeg Eiver about fifteen miles 

 above Fort Alexander, and then I'uns south to Lat. 49°, a little east of 

 Eed Eiver. {R. Bell.)

Passing west on the line of the Canadian Pacific Eailway in the 

 Eocky Mountains, this tree is first met with on the slopes of the Col- 

 umbia valley, near Donald. Thence westward, it becomes more 

 plentiful along Beaver Creek, in the Selkirk Moimtains, but never 

 very common, although becoming a fine tall tree on the mountain sides. 

 (Macoun.) This tree is found on the Hope-Sim ilkameen trail, some 

 miles beyond the summit, on the Sumallow, about the summit between 

 the Coquihalla and Coldwater, on the Hope-Nicola trail, and to the 

 west bank of the Spioos at the trail-crossing. On the^Homathco Eiver 

 it disappears at fifty-one miles from the sea, at an elevation of 2,235 

 feet.. It reappears in the region of heavy rainfall of the G-old Eange, 

 being abundant at Cherry Creek and on the shores of the Great 

 Shuswap and Adam's Lake. Sparingly in the valley of the Tobacco 

 Eiver and other streams south of the Kicking Horse and north-east of
