LOGS REDUCED TO STANDARD BOARD MEASURE.

The following Table gives the number of Feet of Standard Board produced from Logs of 8 to 30 feet in Length, and from 12 to 36 inches diameter.

The first column on the left gives the length of the Log in feet. The figures under D denote the diameters of the Logs in inches.

The number of Square Feet is obtained by the following Rule:-Subtract 4 from the Diameter of the Log, and multiply the remainder by half itself, and the product by the length of the Log, then divide the result by S.

MILL TABLE FOR LOG MEASURE.

The following Table shows the number of Feet in 7-8 square edge Boards any given Log will make, (to be slabbed so as to allow one board for wane.), If it is desired to make it equal to round edge, add 12 per cent. ; if desired in any other thickness, add or subtract as the case may require. L. denotes length in feet,-D. diameter in inches.

Coal is bought at wholesale at the rate of 2240 pounds to the ton, and sold at retail at the rate of 2000 pounds to the ton, screened. of Cubic Feet in 2000 pounds is 38, and in 2240 pounds 43. The average number

To obtain the Solid Content, or Cubic feet of a COAL BIN, take the dimensions by measuring the inside, and if all the dimensions are in feet, multiply the length, breadth and depth together, and the product is the number of cubic feet; but if either of the dimensions are in feet and inches, the whole may be reduced to inches, the length, breadth and depth multiplied together, and the product divided by 1728 gives the number of Cubic Feet.

VALUE OF WOOD AND BARK PER FEET AND CORD.

The price per Cord is found at the top of the column. The Solid Feet are in the left hand column, (under Ft.) opposite which are the prices per foot. 128 cubic feet, or a Cord, or pile, 8 feet long 4 feet wide and 4 feet high, is a cord of wood as established by law in most of the States. If the price of more than one cord is required, the amounts can be readily added or multiplied.

WOOD AND BARK MEASUREMENT-AT SIGHT.

This Table is calculated for Wood 4 feet in length. If the wood be 8 feet long double the products; if 12 treble, and so on. If the wood
should be only 3 feet in length, then deduct from the products; if 3 deduct 1-8. Fractions of a solid foot less than are not counted; half
foot and over is counted as 1 foot.

The Rule for Measuring Wood is, if in feet only, to multiply the length by the width, and that product by the height, and divide the last
product, if for feet, by 16, and if for Cords by 123. But if any of the dimensions be in feet and inches, reduce the whole to inches and inul-
tiply as above, then divide the product by 1728 in order to obtain cubic feet, and then divide the quotient by 128 to obtain cords.
