BULLETIN" 475, TJ. S. DEPARTMENT OF AGRICULTURE. 



topographical features, soil, and cover of the area, the distance of the 

 site from the railroad and base of supplies, the character of the trans- 

 portation necessary to convey the stock and supplies to the camp, 

 the wages paid crews, the efficiency of the crews, the method followed 

 in sowing or planting, the species and amount of seed or stock used 

 per acre and its cost, the size of the operation, and the nature of 

 the weather during operations all are important. Small operations 

 are consistently more expensive per acre than large ones because the 

 former do not continue long enough for the men to become expert in 

 their work. Inclement weather which causes an interruption in 

 operations often materially increases costs, because the men while 

 idle are furnished food. The variation in these factors is so great 

 that it is difficult to do more than estimate approximately the cost of 

 any individual operation. That some idea may be obtained, however, 

 the actual cost of a number of representative Forest- Service opera- 

 tions are shown in Tables 7 and 8.
