CHANGE TO CUBIC-FOOT SCALING CO ULD BE GRADUAL 



Changing the method of log measurement from board feet log scale to cubic 

 feet need not be done overnight „ Certain agencies might blaze a trail for 

 others to follows The United States Forest Service, for example, might 

 lead the way and prescribe use of the cubic foot in future sales of national 

 forest timber,, Such a change would be gradual and should not apply to exist 

 ing contracts e 



There is no doubt that changing from board feet log scale to cubic feet will 

 of course, introduce some difficulties « Many cruises of standing timber are 

 on a board-foot-log-scale basis. To be usable, these cruises must be con- 

 verted to cubic feet by using an appropriate converting factor In most 

 cases the accuracy of cruises is not essentially affected by using a convert 

 ing factor provided it is reasonably appropriate,, In the forest survey of 

 the northern Rocky Mountain region timber cruises are expressed on both a 

 board-foot-log-scale and a cubic-foot basis, the change being effected by 

 using converting factors which show the number of board feet log scale (as 

 indicated by volume tables) per cubic foot.
