114 FOREST commissioner's REPORT. 



men most frequently want to know. It is an entirely different 

 matter from the rate of o;i-owth of trees in volume, thouo-h 

 it is dependent upon it. 



Summary of ^^ Will be Well, probably, to sum up the results 

 results. which havc been worked out in the preceding 



pages in connection with the two sample areas named. At 

 the same time it must be said that no example or pair of 

 examples can possibly meet the conditions of all cases. The 

 factors vary in each case. Cutting and scaling methods used, 

 rates for timber of different sizes, methods and cost of trans- 

 portation, all these matters are different in each case, and 

 they influence greatly the value of growth and consequently 

 the attitude that should be maintained toward it. . The most 

 that work of the nature of this can do is to furnish some of 

 the general factors in the calculation, elements, however, of 

 great value that have not up to this time been determined. 



The following statements embrace the results of the fore- 

 going computations. The examples used were meant to be as 

 representative as might be of Androscoggin conditions in 

 general : 



Growth on small timl)er left in a moderately hard, sys- 

 tematic cut of land may be set at the rate of two to three 

 per cent, compound interest, when volume alone is con- 

 sidered. The rate rises or falls as the cut is more or less 

 severe. 



Measured at start and finish by the Maine scale rule, the 

 sape growth in volume might mean an increase in scale at 

 the rate of from three to five per cent. It might mean a 

 much larger rate, according to the ideas of the person 

 viewing it. 



Putting a foir relative valuation, size being taken into ac- 

 count, on the timber standing at start and finish, the increase 

 in the value of timber so left due to OTowth mi^ht be at the 

 rate of four to six per cent. 



The rate per cent that annual growth bears to the market 

 value of land is a very different matter. It may very 

 greatly overrun the figures which have just been set.
