American Cord-Wood Measure

Timber is measured by the ton of 50 cubic feet of round, or 40 cubic feet of hewn timber. Cord-wood is measured by the cord, which consists of a pile 8 lineal feet long and 4 feet high; and, as the wood is reckoned to be 4 feet in length, contains 128 cubic feet. 34 58752 67 115776 100 172800 6000.

The contents of each lineal foot of the length of the 12 pile is called a cord foot, and contains one- 16 eighth part of a cord, or 16 cubic feet. A 20 New York load of wood is one-third of a cord.

To Find the Cubical Contents the reason that many sticks of timber taper of a Cylinder. Find the area of the circular suddenly, and others are unequal in diameter end, as directed in No. 5987, and then multi- when the average is taken. ply the area by the length of the cylinder; the product will be the cubical content. The same denomination of measurement must be adhered to throughout the calculation, as, if the diameter or area is in inches, the length must be in inches. Thus: to find the cubical content of a cylinder 8 inches in diameter and 3 feet long; we find in No. 5987 that the area of a circle 8 inches in diameter is 50.265 square inches; multiply this by 36 inches (3 feet reduced to inches, the same denomination as the given diameter), and the product is 1809.54 cubic inches, or 1 foot, 81.54 cubic inches.

To Find the Cubical Contents of Spars or Other Round Timber. If the spar or timber were the same thickness through its entire length, the diameter of all parts would be the same, and one measurement would suffice to obtain the correct diameter; its cubical contents could then be found in the same way as for a cylinder; but this is hardly ever the case, as the thickness or diameter is different in every part. If the spar tapers regularly from one end to the other, measure the diameter at each end, add the two measurements together, and divide their sum by 2; this will give the average diameter. A piece of timber of irregular thickness must be measured in portions, each portion extending as far as the tapering is regular, and the contents of the different box 1 foot and 1 inch each way, i. e., length, portions added together to get the contents breadth, and depth, will contain 1 standard of the whole.
