136 TREES OF MINNESOTA. 



trunk covered with a pretty reddish gray, soft, flaky bark: 

 commonly grows about 80 feet in height and 2 feet in diameter, 

 but occasionally reaches a height of 150 feet. Wrongly called 

 Norway Pine, for this species is not found in Norway or any 

 other part of Europe. 



Distribution. Found in northern United States and Can- 

 ada, southward as far as Pennsylvania, but reaches its 

 greatest development in the northern part of Michigan, Wis- 

 consin and Minnesota, where it forms large forests even on 

 sandy or dry soil often interspersed with Jack Pine when 

 young. In Minnesota its range is about the same as that of 

 White Pine but does not extend as far south. 



Propagation. By seeds as recommended for evergreens. 

 The seeds of this pine are very scarce and difficult to obtain 

 on account of the few produced in the cones and the ravages 

 of the squirrels. These animals are so fond of the seeds that 

 they often cut into the cones before the seeds are mature and 

 take the larger part. 



Properties of wood. Light, hard, not very strong, elastic, 

 resinous and durable, harder than White Pine and more liable 

 to crack in drying; yellowish white sapwood and reddish 

 heart wood, conspicuously grained, not durable in contact 

 with the ground. Specific gravity 0.4854, weight of a cubic 

 foot 30.25 pounds. 



Uses. As an ornamental tree and for windbreaks the 

 Norway Pine will stand much more hard usage than the 

 White Pine, especially on light soil; it has a robust, vigor- 

 ous appearance and would undoubtedly be more commonly 

 planted if young plants of it could be more cheaply obtained. 

 Within and near its range it makes a very fine ornamental 

 tree and is very valuable for windbreaks. The principal 

 value of -this timber is for framing, flooring, wainscoting, 

 car sills and ship building. In many ways it is used to take 

 the place of White Pine. In fact, Norway Pine, while in- 

 ferior for general use is frequently mixed with White Pine in 

 lumber yards. While its specific name resinosa would seem 

 to infer the presence of a large amount of resin in this tree, 

 it, in fact, contains comparatively little and is seldom used 

 for the purpose of obtaining resin.
