for logging. It is, how- 

 ever, a very ineffective 

 tool, and when a tree is 

 more than about 2^ feet in 

 diameter, it has first to 

 be split down the mid- 

 dle with wedges. There 

 is no reason why the 

 American one-man saw 

 (^Fig. 31) should not be at once introduced as a substitute. It 

 works very quickly and cuts both ways. 



The use of the circular saw for conversion in the forest is too 

 restricted in this country for a special description of it to be in- 

 troduced here. 



In logging fallen trees a curved cutting edge offers several 

 most important advantages : it suits the natural rocking motion 

 of the hands and arms of the men, it requires less force to pull 

 the saw (since the teeth come successively into action one by 

 one, never several together), the sawdust is never an obstruction 

 (since it is at once cleared), the saw can cut down to the very 

 bottom of the log without risking the teeth against the ground or 

 requiring the log to be raised off the ground, and the operators' 

 hands are always well above the ground and cannot therefore be 

 hurt.
