For the greater proportion of reforestation operations conducted 

 on a large scale, the cost of direct seeding can be kept within from $4 

 to $6 and planting within $10 per acre, provided a spacing of 8 by 8 

 feet is followed. Under more favorable conditions these operations 

 have been carried on at a lower cost. 



Further reductions will be brought about in the future. The pro- 

 duction of nursery stock will undoubtedly be cheapened. The de- 

 velopment of more rapid but efficient methods of sowing and plant- 

 ing or of trees better suited for planting by the rapid methods 

 already in vogue, is quite possible. In many cases the speed of plant- 

 ing can be increased through the use of more adaptable tools kept 

 in the best working condition. Reductions may also be effected 

 through larger assignments which will permit more thorough or- 

 ganization of the work; through confining the planting on a par- 

 ticular Forest at a certain season, to an individual watershed rather 

 than conducting it on several, thus avoiding the duplication of 

 camps, crews, and supervision; and in some cases through allotting 

 fewer species and kinds of stock for use during a particular season.
