DISSECTING (BUCKING) THE BOLES OF THE TREES 



15 



(C) THE MAIN DIVISIONS OF WOODY PRODUCE obtained from dissected boles are:- 



1. Piece stuff, e.g. logs, blocks, construction timber, sold by the foot, the standard, the pound; 



2. Numbered stuff, e. g. poles, posts, mine props, ties, scaffolding poles, shingles, boards, staves, 

 sold by the dozen, by the hundred, by the thousand, &c. ; 



3. Stacked stuff, e. g. industrial cordwood (for insulator pins, bobbins, pulp, tannin, &c.), tanbark 

 and fuel, sold by the cord. In the case of tan bark, 2,240 lbs. are usually considered the equi- 

 valent of one cord.

(D) THE SPECIFICATIONS GOVERNING THE DISSECTION DESCRIBE:- 



1. The dimensions, e.g. the range of length and diameter desired for each section obtainable; 



2. The quality of each section and the defects allowed and prohibited therein, 

 (a) Saw logs for lumber: - 



1. The dimensions. Spruce in New England is often cut 13 feet 4 inches long with a diameter 

 of 5 inches and up. 



For yellow pine logs, any length and any diameter over 8 inches are permissible. 



Hardwood logs for lumber have a length ranging from 6 feet 4 inches to 18 feet 4 inches, 

 arranged in intervals of 2 feet. 



Hardwood logs for staves are cut, in Maine, to the following lengths:- 10', 8", 

 13', 4", 16'. 



Redwood logs are cut 16', 18', 20', 24', 32', 40' long, one year after the trees 

 are felled. 



In Douglas fir, the standard lengths of logs are from 24 feet to 40 feet. 



Export logs of yellow poplar are 8 feet and 16 feel long. 



Jack pine logs for cheap box lumber are often cut 6 feet 6 inches long, the diameters 

 ranging from 4 inches upward. 



2. Treatment. Saw cuts at either end of log should be perpendicular. Branches should be 

 swamped off, knots cut level and laid open. In the case of conifers, the bark is frequently 

 peeled off. Bark rings are sometimes left at the ends. Defects of bole must be concentrated 

 in one log, or must be sawn out. Nosing is required for loose driving and for snaking.
