THE TREES OF HARTSVILLE. 



Long-leaf Pine (Pinus palustris Mill.). 



A very fine, large tree with leaves ten to fifteen inches long, 

 and three in a bundle. The cones are the largest of any Eastern 

 American pine, and the seeds are of good size and edible. With 

 the exception of the swamps and bays, it once covered this whole 

 section in an unbroken forest, but it is now being fast encroached 

 upon by the old-field pine, except in such excessively sandy areas 

 as the Sand Hills.* 



Old-field Pine {Pinus Taeda L.). 



A large tree with leaves about six to ten inches long, and good 

 sized cones. It is second in value only to the long-leaf pine as a 

 timber tree, and it is extensively used by the Carolina Fiber Com- 

 pany, of Hartsville, in the manufacture of paper. This species 

 is very abundant in our section in almost all soils except the sand 

 hills and swamps, and penetrates much farther into the bays than 

 the long-leaf pine. Most thrown out fields are immediately cov- 

 ered with a dense growth of old-field pine. If we are to lose the 

 long-leaf pine over most of our territory, it is fortunate that so 

 valuable a tree as the old-field pine is to take its place. 



Pond Pine, or Slash Pine {Pinus serotina Michx.). 



A small or good sized tree that can hardly be distinguished 

 from the old-field pine except by the cones : these are shorter and 

 broader than those of the last, and usually remain unopened and 

 attached to the tree for several years.f This pine is almost entirely 

 confined to savannas, bays, and edges of swamps, and it is smallest 

 in the savannas. In bays it may reach a height of seventy-five 

 feet or even more. An occasional tree may be found in the

fin my article on the Vitality of Pine Seeds and the Delayed Opening of 

 Cones, in The American Naturalist, Vol. 43, page G77, Nov., 1000, it was 

 shown that seeds taken from unopened cones at various ages up to fourteen 

 years were still capable of germination. It has since been shown that in 

 the case of the Western lodge pole pine seeds may remain alive in unopened 

 cones for 75 or 80 years (See U. S. Forest Service Bulletin 79).
