State carry heavy stands of from 5,000 to 7,000 board feet, and in 

 time the resinous wood may be handled to commercial advantage. 

 The working tables for Idaho can readily be applied in efforts to 

 determine the volume of stumpwood on any area. The average stand 

 to the acre for the entire commercial yellow-pine region of the State 

 may be taken to be 4,000 board feet. 



The yellow-pine region of Utah is scattered over an extensive area, 

 and until a more detailed survey is made it will be impossible to 

 state the value of the stumpwood for distillation purposes. As a 

 rule, it is far from transportation facilities and markets, so that for 

 the present it may be considered as having but a slight bearing on 

 the distillation problem. It has been assumed that the average stand 

 from which the 1917 lumber cut was obtained carried 3,000 board 

 feet an acre. In all probability it was decidedly higher, as the best 

 stands are generally being cut first. This would reduce the number 

 of acres annually cleared, but would not affect the volume of stump- 

 wood.

1 From Forest Service records. 



The commercial stands of yellow pine in Colorado are confined 

 in a large measure to the national forests. They are scattered over 

 nearly a million acres, but the volume to the acre is lower than 

 that in any other State. It is not probable that any value may be 

 derived from this stumpland in the way of distillation products. 



The chief yellow-pine area in South Dakota is located in the 

 Black Hills region. The average stand for the 707,000 acres is 

 4,063 board feet an acre, making the ' volume of stumpwood about 

 two cords an acre, which is thought to be low for distillation pur- 

 poses, as the wood is not especially resinous. 



The stand in Wyoming is so small as to be entirely negligible for 

 the purposes of distillation. 



SUMMARY. 



This brief survey shows that the quantity of stumpwood is enor- 

 mous and that the problem of handling the cut-over areas is of first 

 importance. It is known, however, that not all of these stumps 

 are sufficiently resinous for profitable distillation, under present 

 conditions.
