BULLETIN 153. U. S. DEPARTMENT OF AGRICULTURE. 



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 

 cord wood.

 WHITE PINE (Pinus strobus Liniu). 



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, and though they persist, the knots are usually 

 sound and the timber 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, although somewhat knotty, sells as lumber for 

 from $36 to $38 per thousand feet board measure. White pine is 

 recommended for windbreak planting in the Middle West, since it is 

 an excellent t^ee for the purpose and produces a large amount of 

 timber of good quality.
