STACKED OR CORD MEASURE 



the cord, defective portions may be culled by subtracting from the total stacked 

 volume, a piece whose volume is the square of the diameter in feet multiplied by 

 length in feet. This deduction coincides with the basis of a standard cord of 

 100.5 solid cubic feet and is based on Y^-g cord for each cubic foot subtracted. 

 This method is the basis of the following table: • 



TABLE XXV* 



Measurements of 4-foot Round Spruce Pulpwood — with Cull Factors 

 Based on Solid Cubic Contents 



Prepared by H. L. Churchill for spruce in the Adirondack region, New York. 



Where the contents of the cord are expressed directly in soHd cubic 

 feet, special tables can be worked up for deducting the actual cubic 

 contents for sticks of given diameters. 



The Humphrey Caliper Rule will serve to make deductions based 

 on solid measure, by scaling the contents of. the defective portion as 

 a stick of a given length and diameter. 



113. The Measurement of Bark. Bark, when used for tannin, is stripped off 

 in sheets and piled in cords. At the factory a cord is measured by weight. Eastern 

 hemlock bark must weigh 2240 pounds per cord, when dry. 



The bark peelers are paid by the stacked cord measure, which is in some 

 localities 4 by 4 by 8 feet but more often is required to be full in one or more 

 dimensions, according to local specifications. In New York, the dimensions are
