138 A MANUAL FOB NORTHERN WOODSMEN 



For convenient use in scaling, these figures should be 

 stamped on the bar of a log caliper. They may be so ar- 

 ranged on a bar as to throw out a fair proportion for bark. 

 This system of log measurement is in actual use in but 

 one business concern, so far as known to the writer, yet it 

 is the simplest and most natural measurement for logs that 

 are to be converted into pulp, shingles, excelsior, etc. It 

 is not a difficult matter to arrange a factor or factors for 

 converting cubic measure into board measure. 



SECTION II 

 CORD WOOD RULE 



The figures given in the table on page 239, those for cord 

 measure, are not cubic feet of solid wood, but what have 

 been called " stacked cubic feet " ; the space which wood 

 will occupy in a pile. 128 of these make a cord. Like the 

 preceding, these figures are ordinarily placed for conven- 

 ient use on the bar of a caliper rule. 



These figures have been long and widely tested in prac- 

 tice, and when used as designed have given satisfaction. 

 Logs should not be measured in too long lengths, for whole 

 trees measured in this way may not hold out. Again, 

 small, crooked, and knotty timber will pile up rather more 

 cords than the rule gives. On a good quality of pulp wood 

 these figures yield -just about the same return as the re- 

 sults of piling. For further details see Section VIII, on 

 cord measure. 



SECTION m 



THE NEW HAMPSHIRE RULE 



The New Hampshire Log Rule is exactly the same as 

 the last in principle, only an artificial unit of measure has 

 been created. The " cubic foot " of New Hampshire log 

 measure is 1.4 times the cubic foot of standard measure, 

 and nearly twice the foot of the cord wood rule. The New 

 Hampshire law regarding the matter is as follows : 



All round timber, the quantity of which is estimated by the 

 thousand, shall be measured according to the following rule: A
