FOEEST PLANTING IN THE EASTERN UNITED STATES. 



29 



Where white pine grows well there is no object in planting it in 

 mixture with other species. In certain regions, however, particularly 

 in New England, the tree is subject to attack by the white pine weevil 

 (Pissodes strobi Peck), which kills the top of the leading shoot through 

 a year or two of its growth. A new leader is ordinarily formed by 

 one of the side shoots, which in turn is subject to attack. The result 

 is a crooked, unsightly tree, whose value for timber is considerably 

 impaired, especially in stands grown on a short rotation, when there 

 is not sufficient time for the crooks to be covered through growth of the 

 bole. Wherever the weevil has appeared it would be better to plant 

 Norway pine with the white pine than to plant the latter species 

 alone. Young Norway pine grows as rapidly hi height as the white, 

 and though its lumber is less valuable, it is less subject to attack 

 by the weevil. 



In Table 7 the white pine plantations listed are all in the Middle 

 West. Similar figures for New England plantations appear in other 

 publications of the Forest Service and of various New England 

 States. For the Middle West white pine stumpage has been given 

 a value of $10 per thousand feet for stands with an average diameter 

 under 11 inches, and of $12 for stands 11 inches and over, both of 

 which are very conservative. White pine is usually cut by small 

 portable sawmills, and the felling and sawing together do not cost 

 more than $12 per thousand feet board measure for lumber which 

 brings from $36 to $38 per thousand.
