1 From "Forest Mensuration of the White Pine in Massachusetts," by Harold O. Cook. Based on 
measurements of 177 sample plots, one-quarter and one-eighth acre in size, in stands of different ages and 
qualities. Yields scaled by the use of volume tables 24, 26, and 27. 
Relation of Taxes and Other Costs to the Stumpage Value axd their 
Effect upon Length of Rotation. 
Table 34, which is based on the stumpage prices in Table 11 and the cost data in 
Tables 12 and 13, gives the proportion of the taxes and other expenses to the stumpage 
value, and shows how the expenses, distance of haul, interest rate, and site quality 
affect the length of the financial rotation. 
Table 34.— Taxes and other expenses in per cent of the stumpage value, where distance 
from stand to local market permits a daily haul of 1,000 and 3,000 board feet of lumber 
per team. (See p. 31.)
