1 Taken from "A Manual for Northern Woodsmen." Mr. Austin Gary, the author, considers 

 tables XL, XLI and XLII applicable to other coniferous species with certain modifications. For 

 balsam fir he advises a deduction of 8 per cent. 



2 Based on 2500 trees scaled in 16-foot log lengths up to 6 inches in diameter by the Maine log 

 rule and discounted from 5 to 10 per cent.
