This table is intended to be used simply as a guide. The allowances for taper 

 should be varied to conform to the actual taper. 



On the National Forests in Alaska and on the west sl()])o of the 

 Cascade Mountains in Washington and Oregon logs up to and 

 including 32 feet long will ))e scaled as one log; lengths from 34 

 feet to 64 feet, inclusive, will be scaled as two logs, dividing them 

 at the center as near as may be in even feet, for example: A 34-foot |^
