30 PLANTING OF WHITE PINE IN NEW ENGLAND. 



When this has been done acorn planting has usually been successful 

 on open ground. But where other species spring up naturally it has, 

 as a rule, been unsuccessful. White oak, though a more valuable tree 

 than either red or scarlet oak, is not adapted to mixture with white 

 pine, owing to its slow growth. Red and scarlet oak may be used in 

 mixture with white pine throughout its entire range. 



CHESTNUT. 



Chestnut is a valuable tree for use with white pine. While the oaks 

 are slightly slower than pine in growth, chestnut is a little more rapid. 

 It has the advantage, too, of being valuable for fence posts, even when 

 young, so that when it begins to overtop the pine it may be cut out 

 profitably. It takes from fifteen to twenty -five years for pine to 

 become sufficiently large to completely shade the ground; the chestnut 

 may then be cut and used for posts, telegraph poles, or railroad tics. 

 Chestnut may be used in mixture with white pine throughout the New 

 England States, New York, Pennsylvania, New Jersey, Delaware, 

 Maryland, and Virginia, and in the Appalachian region south to 

 Georgia and Alabama. 



SCOTCH PINE. 



The mixture of Scotch pine Avith white pine is satisfactory so far as 

 the growth of each species is concerned. There is little advantage 

 gained, however, for it is as expensive to plant Scotch pine as white 

 pine, and the result is a tree of a smaller timber value. The Scotch 

 pine is not a native of America, but its range for economic planting 

 extends throughout the range for white pine, and west as far as the 

 Plains. Scotch pine is hardy under a great variety of conditions, but 

 in almost every case is of less value than some other species. 



BED PINE. 



In several plantations red pine has been used with white pine. The 

 result is rather unsatisfactory, for in most cases it grows more rapidly 

 than the latter, and, when planted in equal quantity with it, shades it 

 too heavily with its broad, spreading crown. In New England the 

 differencs in growth is accentuated by the dwarfing effect of the white- 

 pine weevil. The result is that the white pine is gradually superseded. 

 In a 27-year-old forest of these two species, white pine showed an 

 average height growth of 27. 5 feet, and red pine of 34. 9 feet. Their 

 relative growth is well shown in the plantation of Mr. Isaac Adams, 

 in Moultonboro, N. H., where the red pine invariably overtops and is 

 usually detrimental to the growth of the white pine. 



In one respect the mixture of red and white pine behaves like that 

 of larch and white pine. White pine is more tolerant than red, and 

 consequently shades out the side branches of the latter, forming -i 

 clear bole, while the branches of the white pine continue, so that the
