whence it is sometimes called the Spruce Pine. The term 
Yellow Pine arises from the color of the wood as contrasted 
with that of the foregoing sort, which is white. The leaves 
of this species are long and flexible, arranged in pairs upon 
the branches, and have a fine dark green color. The cones 
are very small, scarcely measuring an inch and a half in 
length, and are clothed on the exterior with short spines. 
The growth is quite slow. 
The Yellow Pine is rarely found above Albany to the 
northward, but it extends as far south as the Floridas. It 
grows in the greatest abundance in New Jersey, Maryland, 
and Virginia, and sometimes measures five or six feet in 
circumference. In plantations, it has the valuable property 
to recommend it, of growing on the very poorest lands. 
The Pitch Pine ( P . rigida) is a very distinct sort, 
common in the whole of the United States east of the 
Alleghanies. It is very stiff 1 and formal in its growth when 
young, but as it approaches maturity, it becomes one of the 
most picturesque trees of the genus. The branches, 
which shoot out horizontally, bend downwards at the 
extremities, and the top of the tree, when old, takes a 
flattened shape. The whole air and expression of the tree 
is wild and romantic, and is harmonious with portions of 
scenery where these characters predominate. Thq leaves 
are collected in threes, and the color of the foliage is a dark 
green. The cones are pyramidal, from one to three inches 
long, and armed with short spines. 
The bark of this kind of Pine is remarkably rough, 
black, and furrowed, even upon young trees ; and the wood 
is filled with resinous sap, from which pitch and tar are 
copiously supplied. The trees grow in various parts of 
the country, both on the most meagre soils and in moist
