Although it grows naturally only in saturated soil, it sometimes 

 takes possession of comparatively dry ground from which long-leaf pine 

 has been cut off; a circumstance which has led some uneducated people 

 to believe that the long-leaf does not reproduce itself after lumbering, 

 but mutates into another species. Some writers on forestry also have 

 been misled into thinking that P. Elliottii is destined to take the place 

 of P. palustris in the not distant future. But the range of the slash 

 pine is much the smaller of the two, and it has shown no evidence of 

 extending its boundaries since it was first recognized as a distinct 

 species, about 35 years ago. 



It is not injured perceptibly by fire, except when very young. Its 

 economic properties are practically the same as those of the long-leaf 

 pine, from which it is seldom distinguished in the lumber and naval 

 stores markets. Its distribution corresponds approximately with that of 

 the sea-island cotton crop, except that this cotton is not now raised west 

 of the Chattahoochee River, while the pine extends nearly to the Pearl 

 River. 



The Florida Spruce Pine (Pimis clausa), a near relative of P. Vir- 

 giniana, is the least widely distributed of all the eastern conifers, being
