The Pines. 329 



They bear fruit early and show a tendency to self seeding. Upon 

 Nantucket, we have noticed that they spread most toward the east 

 or southeast under the effects of prevailing winds, and this will 

 generally be found the case elsewhere. These plantations are liable 

 to suffer from fire, and occasionally from insect ravages. 



1334. In Virginia this species is sometimes called the "Black 

 Pine." It grows from 30 to 50 feet in height. The wood of the 

 pitch pine, is coarse, resinous, and heavy, and generally very 

 knotty. It is sometimes used in making tar, but is not of value 

 in commerce, although from its resinous properties it makes an ex- 

 cellent firewood. 



1335. The variety serotina, known as "Pond Pine," is a southern 

 species, growing in swamps to a height of 40 to 50 feet. It has 

 sometimes been used for the masts of small vessels. 



1336. SPRUCE, OR JERSEY-PINE (Pinus mops). This pine, in 

 New Jersey, Maryland, and southward to Florida, shows a tendency 

 to spread and occupy vacant lauds. It is variously known as " Ce- 

 dar-Pine," " River-Pine," and " Scrub- Pine," and grows to from 20 

 to 40 feet in height and from 12 to 18 inches in diameter. It is 

 chiefly valuable for firewood. 



1337. PRICKLY PINE (Pinus pungens). This is sometimes called 

 the " Table-Mountain Pine." It grows from Pennsylvania south- 

 ward, but to best advantage in North Carolina. It is common on 

 the eastern spurs of the Blue Ridge, but not further west. It 

 grows from 30 to 50 feet in height, and from 12 to 20 inches in di- 

 ameter. 



1338. SHORT-LEAVED YELLOW PINE (Finns mitis). This pine is 

 widely diffused, but grows to best size and quality in the South- 

 western and Southern States, where it is used for lumber. It usually 

 grows from 40 to 60 feet in height, and from 15 inches to 2 feet in 

 diameter. The heart- wood is fine grained, but moderately resinous, 

 but the sap-wood is perishable. 



1339. THE SPRUCE PINE (Pinus glabra) is a southern species, 

 found in South Carolina, Georgia, and Florida. 



1340. GRAY OR SCRUB-PINE : BANK'S PINE (Pinus Banksiana). 

 This is a northern species, occurring from Maine westward to North- 

 ern Wisconsin and the upper peninsula of Michigan. It is found in 

 Canada and far northward in British America, growing from fifteen 

 to thirty feet in height, but nowhere of size to make it suitable for
