2] § APPENDIX.

TO MEASURE LOADS OF WOO!).

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 3 inches high 3

7 ft. 6 in.—7,5 and 4ft. 2 in. =4,167 and 2 ft. 3 in2.25 ; then, 7.5 × 4,167–31,2525 × 2,25=70,318.125 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 height 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 3 feet 9 inches wide and 2 feet 6 inches high. By Duodecimals. By Decimals.

The foregoing method is concise and easy to those who are wel) acquainted with Duodecimals, but the following table will give he pontent of any load of wood, by inspection only, suffieiently exact for tommon practice; which will be found ver Nonvenient.

First measure the breadth and height of your load to the nearest 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 content of the inches on the right and divide the sum by 12, and you will have the rue content of the load in feet and inches.

JNote.—The contents answering the inches being always small, may oe added by inspection.

EXAMPLES.

1. Admit a load of wood is 3 feet 4 inches wide, and 2 feet 10 inches nigo, required the content.— hus, against 3 feet 4 inches, and under 2 feet, stands 40 inches; and under 10 inches at top, stands 17 inches: then 40+17–57, 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 8 inches; required the con

tent.—
Thus, with breadth 3 feet 0 inches, and under 2 seet atop, stands 86

inches; and unders inches, stands 12-inches: now 55 and 12 make 48, two answer in inches; and 48+12–4 feet, or just half a cord. 3. Admit the breadth to be 3 feet 11 inches, and heights feet 9 inches, uired the content. Inder 3 feet attop, stands 70; and under 9 inches, is 18: 70 and 18, make o or 7 st. I q.--inches, the answer.
