80 Forest Club Annual 



Data as to the costs of carrying on reconnaissance work 

 were difficult to obtain, but from the figures available, as the 

 following table shows, it seems to average about four cents an 

 acre. The costs varied greatly according to the character 

 of the country worked, the amount of accuracy required, the 

 distance from the base of supplies, etc. One factor which 

 greatly increased the cost was the necessity of keeping a base- 

 line crew in the unsurveyed and poorly surveyed country.
