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 and 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.)
