topographical features, soil, and coA'er 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.

ferent regions tjy various metliods.
