FOREST 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 in 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.
