growth of the larger trees ; this thinning netted over $30 per 

 acre and changed the stand from one in which many trees were 

 growing very slowly to one in which a few trees are growing 

 rapidly. 



The principal points of advantage of the present over the 

 preceding systems are: better watershed protection, trees left 

 will grow faster, needed thinnings are secured in young stands, 

 windfall is negligible, the total cut of large timber is increased, 

 and the over producton of small material is stopped. 



In the Lodgepole region it is considered advisable as a fire 

 protective measure to dispose of brush by burning it currently as 

 the cutting proceeds in the safe season, as is entirely feasible, or 

 by piling it in the summer for future burning.
