Native Trees of Canada 



It has the smoothest bark of any eastern pine. On limbs and young trunks 

 under 6 in. in diameter it is, as a rule, greenish-brown in colour and quite smooth. 

 Later it becomes roughened by shallow, flat-topped, broad, longitudinal ridges, 

 greyish-brown in colour. On account of its thin, resinous bark it is greatly subject 

 to damage by fire. 



The branches usually grow out at right angles to the trunk in more or less 

 regular whorls of five. On old trees, or those growing in crowded stands, this is 

 not so apparent. The crown is more or less cone-shaped in young trees, becoming 

 flat-topped when old. 



Its wide-spreading roots and deep tap-root make it very wind-firm and, as a 

 rule, it is only the much-exposed mature trees that are overthrown. 



WHITE PINE 



The needle-like leaves grow in bundles of five and are from 3 to 5 in. long, 

 soft, delicate, and of a clear light green colour. In cross-section the leaves are 

 triangular. It is the only nativ^e pine east of British Columbia with five leaves 

 in a bundle, and is, therefore, not likely to be confused with any other. 



The cones are from 5 to 10 in. long, slender, curved, and stalked. The scales 

 are thin and have no prickles at their tips. 



The white pine ranges from Newfoundland to Manitoba. It does not extend 

 north of the height of land dividing the waters of the St. Lawrencfe and the Great
