The tree is decidedly intolerant, and a rather wide spacing, 6 by 
8 or 8 by 8 feet, is advisable, or it may be planted in mixture with 
white pine on soils adapted to ‘both species. In the latter case a 
spacing of 6 by 6 feet, with the two species alternating, will probably 
give the best results. : 
Stumpage values for Scotch pine in the Middle Western States are 
placed at $8 per thousand board feet for lumber and $2 per cord for 
cordwood.

WHITE PINE (Pinus strobus Linn.). 
White pine seems well suited to the climate of the whole eastern 
portion of the country from New England to Iowa. It is not par- 
ticularly exacting as to soil, but requires good drainage. It flourishes 
on the worn-out pasture lands of New England, on the almost pure 
sands of Cape Cod, and on the good agricultural soils of the Middle 
West. It will also undoubtedly thrive on some of the poor, sandy 
farm lands of the Indiana and Ohio region. 
White pine is fairly tolerant, and in order to secure a clear bole 
very close spacing, 4 by 4 feet or 4 by 6 feet,is necessary. In practice, 
however, a spacing of 6 by 8 feet to 8 by 8 feet is usually close enough. 
In a stand 50 years old, spaced 6 by 8 feet, the branches die to a 
height of 40 to 50 feet, waa though they persist, the knots are usually 
sound and the pal of fairly good quality. In a three-row wind- 
break in eastern Iowa, 52 years old and spaced 6 by 7 feet, the owner 
cuts timber which, photon somewhat knotty, sells as ever for 
from $36 to $38 per thousand feet board measure. White pine 1s 
recommended for windbreak planting in the Middle West, since it is 
an excellent tree for the purpose and produces a large amount of 
timber of good quality.
