AMERICAN FORESTRY 



PLANTATION OF (1) JACK P-NE AND (2) RED PINE 



All the trees were planted at the same time, but the Jack 



Pine is almost twice as high as the Red Pine. 



In the United States there are twelve species of soft 

 |)ine and twenty-three of hard pine. The white pine is 

 the only Eastern species belonging to the soft pine group. 

 It has a number of other common names, among them 

 being "pumpkin pine," "cork pine," and "soft pine." 



A THRIFTY PURE STAND OF YOUNG PITCH PINE 



The most typical hard pine of the Northeast has more common 

 varieties than any other pine in that section. 



Western white pine and sugar pine are the two most im- 

 portant Western species belonging to the soft pine group. 

 Twelve of the twenty-three hard pines native to the 

 United States occur in the Eastern and Southern States. 

 Some of them have a dozen or more common names. It 



would not be possible to describe the twelve species in 

 a single article ; hence, five species of hard pine occur- 

 ring in the northeastern part of the United States have 

 been selected for special consideration in tliis article. 

 Other species will be described in later numbers of 

 "American Forestry." 



The five pines considered in this article are: 



(1) Northern jack pine; also called Bank's pine. (2) 



TYPICAL OPEN-GROWN PITCH PINE 



It can be regenerated naturally with success and is here 



surrounded by a dense stand of its young offspring. 



Red pine. (3) Pitch pine. (4) Jersey or Scrub pine. 

 (5) Table mountain pine. 



The last two species are not strictly pines of the north- 

 east, but they extend northward as far as northern Penn- 

 sylvania, and occur along the Allegheny Mountains in 

 mixture with trees typical to the forest flora of the 

 northeast. 



PITCH PINE MIXED WITH HARDWOODS 



It usually occurs so, but stands over its companions because 

 of its fire-resistance.
