WOOD 127 



To find the weight of a board foot of the foregoing 

 woods, divide the weight given by 12. 



Measurement for sale. Lumber is sold by the board 

 foot, which is 1 square foot in area and 1 inch in thickness. 

 Example: A board 1 inch thick, 10 inches wide, and 12 feet 

 long would contain 10 board feet. The same board 2 inches 

 thick would contain 20 board feet. The number of board 

 feet in lumber less than 1 inch in thickness is figured the 

 same as though it were 1 inch thick. A board }4 inch 

 thick, 10 inches wide, and 12 feet long would be counted 

 as 10 board feet. The price on lumber is quoted at so 

 much per thousand board feet, excepting special forms and 

 small sizes put up in bundles, which are quoted by the 

 lineal foot or by the bundle. In a lumber order, when all 

 dimensions are given, the number of pieces should be stated; 

 when mixed widths and lengths can be used, the number 

 of board feet should be specified.

Conservation of lumber. The rapidity with which forest 

 areas are being reduced by lumber operations, the slowness 

 with which lumber-producing trees grow, and the result- 

 ing advance in lumber prices have led to the using of parts 

 of trees and the cutting and sawing of species of trees that 

 at one time were not considered as suitable for lumber, such 

 material being used for barrels, boxes, and temporary con- 

 struction where it is covered and well protected. To pre- 

 vent further depletion of the forest areas, special efforts
