TO MEASURE LOADS OF WOOD. RULE. Multiply the length by the breadth, and the product by the depth or height, which will give the content in solid feet; of which 64 make half a cord, and 128 a cord. EXAMPLE. How many solid feet are contained in a load of wood, 7 feet 6 inches long, 4 feet 2 inches wide, and 2 feet inches high? 7 ft. 6 in. 7,5 and 4 ft. 2 in.=4,167 and 2 ft. 5 in= 2,25; then, 7,5x4,167 $1,2525×2,25=70,318125 solid feet, Ans. = But loads of wood are commonly estimated by the foot allowing the load to be 8 feet long, 4 feet wide, and then 2 feet high will make half a cord, which is called 4 feet of wood; but if the breadth of the load be less than 4 feet, its height must be increased so as to make half a cord, which is still called 4 feet of wood. By measuring the breadth and heighth of the load, the content may be found by the following RULE. Multiply the breadth by the height, and half the product will be the content in feet and inches. EXAMPLE. Required the content of a load of wood which is 5 feet 9 inches wide and 2 feet 6 inches high. By Duodecimals. By Decimals. 7 F.in. S 9 2 6 F. 3,75 2,5 84 inches over. The foregoing method is concise and easy to those who are well quainted with Duodecimals, but the following Table will give the Content of any load or wood, by inspection only, sufficiently exact for common practice; which will be found very convenient. A TABLE of Breadth, Height, and Content. TO USE THE FOREGOING TABLE. First measure the breadth and height of your load to the Dearest average inch; then find the breadth in the left hand. column of the table; then move to the right on the same line till you come under the height in feet, and you will have the content in inches, answering the feet, to which add the cortent of the inches on the right and divide the sum by 12, and you will have the true content of the load in feet and inches. NOTE.-The contents answering the inches being always small, may be added by inspection. EXAMPLES. 1. Admit a load of wood is 8 feet 4 inches wide, and 2 feet 10 inches high; required the content. Thus, against 3 ft. 4 inches, and under 2 feet, stands 40 inches; and under 10 inches at top, stands 17 inches: then 40+ 1757 true content in inches, which divide by 12 gives 4 feet 9 inches, the answer. 2. The breadth being 3 feet, and height 2 feet 3 inches; required the content. Thus, with breadth 3 feet 0 inches, and under 2 feet atop, stands 36 inches; and under 8 inches, stands 12 inches: now 36 and 12, make 48, the answer in inches; and 48-12-4 feet, or just halfa cord. S. Admit the breadth to be 5 feet 11 inches, and height feet 9 inches; required the content. Under S feet at top, stands 70; and under 9 inches, is 18: 70 and 18, make 88÷127 feet 4 inches, or 7 ft. 1 qr. 2 inches, the answer. TABLE I.
