MEASUREMENT OF TIMBER. 



The unit of board measure is a superficial foot 1 inch thick. 



Besides inch-boards, plank and scantling are usually 

 bought and sold by board measure. 



Round, sawed, or hewn timber is bought and sold by 

 the cubic foot. 



Pine and spruce spars, from 10 to 4 % inches in diameter 

 inclusive, are measured by taking the diameter, clear of 

 bark, at one-third of their length from the large end. 



Spars are usually purchased by the inch diameter; all 

 under 4 inches are considered poles.
