Would not such a report be valuable to you in the general 

 handling of your lands, or in the buying, selling or borrowing of 

 money thereon ? 



In scientific handling of forest properties it is possible to go 

 still further. By analyzing carefully the different trees there 

 may be determined the yield which may be cut from the forest 

 at stated periods without depletion of principal. 



This knowledge is of especial value to land owners and to 

 mills owning their own timber lands. For lack of this knowledge 

 in the past many serious mistakes have been made and losses 

 incurred. By cutting more frequently or more thoroughly than 

 the increase would permit some lands have become seriously 

 depleted without the owner's knowledge until it was too 



late to save them. 

 One method of ar- 

 riving at a knowl- 

 edge of future 

 yields, in a forest 

 containing many 

 ages of growth, is 

 as follows:

Sample acres are 

 measured through- 

 out the tract, and 

 the trees within 

 these acres meas- 

 ured as in obtaining 

 a present estimate. 

 This work may 

 be done in the same 

 manner as in esti- 

 mating, but smaller 

 diameters will be 

 taken into account 

 than if the estimate 

 is being made for 

 present growth only. 

 Even the seedlings 

 will be counted on
