If it is allowed to grow to 32", the butt log will have 

 87$ clear wood. 



Pruned trees should be kept growing at a rapid rate, 

 otherwise investments in pruning will be an excessively 

 long time in yielding a return. Clear lumber of white 

 pine, ponderosa pine, lodgepole pine, and spruce is worth 

 from about $2^0 to $290, which is 2JQ% more per thousand 

 board feet than No. 2 common lumber. These values 

 converted back to the forest indicate that if present 

 costs and values continue, each dollar spent in 

 thinning will produce k to h$ dollars in added yields, 

 and each dollar spent on pruning will produce 9 to U$ 

 dollars extra income.

The Agricultural Conservation Program has practices
