i Assessments assumed to be made at 5-year intervals, on the basis of the stumpage values given in Table 

 11, and the taxes for each 5-year period (accumulated as an annuity) carried at compound interest to the 

 end of the rotation. The figures given in the table are thus the sum of the accumulated taxes for the last 

 5-year period plus those for all preceding 5-year periods at compound interest to the specified year. 



RETURNS TO BE EXPECTED. 



The value of an investment in raising white pine may be deter- 

 mined by finding either (1) the precise rate of interest at which the 

 stumpage value exactly equals the cost of growing, or (2) the amount of 

 surplus profit when the stumpage value exceeds the cost of growing, 

 computed at any desired rate of interest. The first of these methods 

 is illustrated in Table 14, and the second in Tables 15, 16, and 17, 

 which show the highest surplus profit or the least loss resulting when 

 the costs are computed at 4, 5, and 6 per cent compound interest. 

 From Table 14 it is apparent that the rate of interest is highest in 

 quality I stands, close to market, which were started by natural 

 seeding; and that it is lowest in planted stands in quality III situa- 

 tions, at some distance from market. This table also shows that 

 investments which return a high rate of interest mature earlier 

 than those yielding a lower rate. 



These figures can be used safely in estimating the returns from 

 investments in which the costs are no higher and the anticipated 

 yields no lower than those given in preceding tables. It should be 

 remembered, however, that they are based on the yields of fully 

 stocked stands, and in using them it is well to allow for understocked 

 and unmerchantable portions of the stand by assuming the area to be 

 smaller but fully stocked. A deduction of from 10 to 20 per cent of 

 the area, depending upon intensity of management, should be 

 ample.
