Certain Modifications of Costs 



In General : It is believed that the costs given in the preceding tables 

 represent as fair averages of the cost of growing timber by means of 

 good forestry practice as can be given for the conditions on the west side 

 of the Cascades in the Pacific Northwest. It is, however, obvious that 

 average figures, no matter how correct, cannot be applied directly to all 

 individual cases. In so far as the first costs in a specific case are known 

 to be susceptible of modification, the final costs may be enormously modi- 

 fied. For example, it is entirely probable that much land which is already 

 stocked with young growth could at the present time be bought at the 

 rates specified in the tables, thus saving the cost of stocking entirely and 

 perhaps several years' interest on other costs. This would greatly increase 

 the possibilities of profit on the area in question, because in forestry every 

 dollar saved at the beginning of the rotation may mean from $5.00 to 

 $50.00 at the end, according to the interest rate. Likewise land already 

 stocked with timber might be bought below the price specified, in which 

 case, still more could be saved.
