518. Yellow pine is a native of the pine forests from New England to Georgia. The wood is much used in America for many purposes of the carpenter. Mr. Fincham considered it of great value for the masts and yards of the larger classes of ships.* The timber is imported into England chiefly from Quebec.

Another species of yellow pine (Pinus mitis), thought by

* ' Outline of Ship-building.' some to be the same as the Pinus variabilis, called the New-York pine is found in great abundance in the middle states and throughout the whole of North America, where it is much used for framework, etc. The heart-wood of this species is fine-grained, moderately resinous, strong, and durable; but the sap-wood is very inferior, decaying rapidly on exposure to the weather; it is more durable and of greater strength than the white pine, but does not attain so large a size. The tree grows to a height of 50 or 60 feet, the diameter being about 18 inches.

In the southern states of America the Pinus mitis is known as "spruce pine" and "short-leaved pine," to distinguish it from the long-leaved or southern pine (Pinus Australis), which is seldom met with higher north than Norfolk, Virginia. The southern pine, which is called Georgia pine in England and the West Indies, is also called yellow pine and sometimes pitch pine in the northern parts of the United States.
