FOREST TREES. 213 
This species is found on the Blue Ridge in Vir- 
ginia, and southward on the summits of the Alle- 
ghany Mountains. It grows to the height of forty 
or fifty feet, with something of the habit and general 
appearance of the Scotch Pine, but with more nu- 
merous branches. The cones are usually in whorls, 
and remain on the branches many years. Until

uncertain how far north it will prove hardy, but it is 
cultivated by Mr. Douglas at Waukegan, Ilinois. In 
its native localities its timber is not highly esteemed ; 
and as it is not remarkably beautiful, its principal 
use will probably be to enrich the collection of the 
amateur. 
13. Pinus mitis—Yellow Pine. 
Leaves, dark green, in pairs, sometimes in threes, 
three to five inches long, with long sheaths, slender, 
channeled; cones, oblong-conical or ovoid, two 
inches long; scales, tipped with a small weak prickle. 
The Yellow Pine is extensively diffused through- 
out the Atlantic States from New England to Florida. 
In the west it is found in Kentucky, Tennessee and 
Missouri. It grows sparingly in Southern Mlinois, 
and I have seen small trees among the sand hills at 
the south end of Lake Michigan. Considerable quan- 
tities of lumber of this species were formerly brought 
to St. Louis from the neighborhood of the Gasconade 
river, and sold under the name of Gasconade Pine. 
The ordinary height of the Yellow Pine is fifty or 
sixty feet, but in favorable situations it often much
