SCOTCH PINE 175 



struction when large enough for the saw, and for all pur- 

 poses to which small, straight, and not very strong wood 

 can be put. Growing as widely as it does, Lodgepole Pine 

 is of much commercial value especially in regions where 

 nothing better can be found, and fortunately, it is sold 

 under its true name. 



It is a prolific seeder, but may not open its cones for 

 years unless the trees are killed by fire. When that occurs 

 natural reproduction will take place to a greater extent 

 than with almost any other tree, but it will not so happen 

 when the trees are otherwise destroyed. It is practically 

 the only species where reproduction mainly depends upon 

 the loss by fire of the parent seed-producing tree. The 

 seeds can endure considerable heat, and this heat seems 

 essential to their release from the cones and probably aids 

 in their germination. It bears seeds when quite young, and 

 if properly cared for, and the ground burned at the right 

 time, natural reproduction will usually be complete. As it 

 is emphatically a light-demanding tree, it must be grown 

 in close stands to be of commercial value. When it attains 

 its proper height, growth thinning would be advantageous. 

 It is not known that any attempt at artificial reproduction 

 has been made. Where clean cutting has taken place, re- 

 generation does not occur to such an extent as would be 

 necessary to produce a stand sufficiently dense ; and such 

 trees as may be left for any cause are soon blown down or 

 die from changed surroundings. Gathering and heating the 

 cones to obtain the seed, and then planting them, or burn- 

 ing the tract before cutting, must take place to insure sat- 

 isfactory reproduction.

THIS foreigner comes to us with high recommendations 

 from the regions of its natural as well as its adopted home 

 abroad. It is widely distributed throughout Europe and 

 northern Asia, and is a very important timber tree on the
