Description: The results of testing the Forest Service standard tree grades and sawlog grades for eastern white pine on an independent sample of 75 trees and 299 logs in southwestern Maine. The total predicted value of the 75 trees was 3 percent higher than the actual value. The total predicted value of the 299 logs was 2 percent higher than the actual value. The differences between the actual and predicted values are small enough to be of no practical importance.
