of the root of the tract . 



I thinh: this is one of the vital points inthe mind 

 of the average lumberman. "7e felt that this gave us a very 

 unsatisfactory teelinr; ahcut where we woro to got off on 

 the fir and oodar. It seems to ne it is ver^r like a layman 



trying to compete with a lawyer. 7ith a fair decree of coin- 





 mon sense I thin]: the lumberman can deduce the result of 



th 3 marliing ac a whole as indicated in the cample marking .- 

 "but the lumberman is not a forester. Your marfcin^ is the 

 result of a set of scientific principles as to which the 

 average liunbornan is densely ignorant, and v;hen the lumber- 

 man is ashed to deduce "bacli to principles he simply can't 

 do it. The point is that not Imowinc; all of the different 

 principles and the correlation of those principlec he is 

 utterly miaole to tahe the principles, t::o use of Y/liicli he 

 may understand in tlie sample maiding, cind ap_.ly them to the 

 halanco of the tract "because each acre liar: certain charac- 

 teristic principles of its o\vii* He may understand the 

 fixed principle, "but change the facts, introduce a new ele- 

 ment, and he is uiiahle to tell whether the ne-v; eloinent will 

 rnahe the transaction unprof itahle or not. 



I thin!: to the averar;e lumoerman the sample marlting 

 is ver^ littje indication as to what the "balance of the

tract -rill cut. If you had an absolutely uniform tract it 



would he a different matter, hut tracts don r t run that way.
