LOGGING 



Saws may be fitted by a member of the saw crew or by a 

 regular filer, who can fit from twelve to fifteen saws daily. 

 Where a greater number is required the work of fitting may 

 often be done to advantage in a filing shop at the camp.

When the felhng crew does the log-making, from one to two 

 sharp saws are provided each day, otherwise a sharp saw is 

 furnished every other day. 



Saws filed daily are serviceable for a period of from two to 

 four months and are then turned over to road-making crews and 

 other laborers who do not require high-grade tools. 



POWER FELLING MACHINES 



There has not been a satisfactory power-driven tree-felling 

 machine placed on the market. Machines of various types have 

 been patented and offered for sale but they have not proved of 

 practical value.
