SYLVICULTURAL NOTES ON WEYMOUTH PINE. 307 



demanders and shade-bearers. It is storm-firm, and 

 resists snow and rime well. 



Soil It has been found to do best on deep porous, 

 fresh, loamy sands, but accommodates itself to dry 

 poor soils, as well as to moderately swampy ground ; it 

 seems however to avoid calcareous soils. It resembles in 

 these respects the Scotch Pine, but demands perhaps 

 a little more moisture in the soil, and is generally a little 

 more exacting. 



d. Shape and Development. 



Weymouth Pine develops a straight and undivided 

 stem, with a fairly dense crown, which in crowded 

 woods is restricted to the upper part of the stem. 



During the first three or four years it grows more 

 slowly in height than the Scotch Pine, which it 

 generally catches up by the eighth or tenth year, when 

 it keeps ahead of it, reaching a maximum height of 

 120 feet or even more. In America, trees of 150 feet 

 in height are frequently seen. Grown in crowded woods 

 it produces a cylindrical stem, but when grown in the 

 open it tapers considerably. Its volume-growth is 

 greater than that of Scotch Pine. The root-system 

 is deep-going, similar to that of Scotch Pine. It 

 is said to reach an age of 400 years in its natural 

 home. 



e. Reproductive Poiver. 



The tree commences bearing full crops of seed when 

 about 30 years old ; these occur every 2 or 3 years, but 

 a certain quantity of seed is produced almost every 

 year.
