Weights and Measures: Hence

Hence 27 bricks are required to make a cubic foot without mortar. But it is assumed that mortar fills of the space. The first step is to find the number of cubic feet in the wall by multiplying the length, height, and thickness together in feet, and if the bricks are of this size multiply the number of cubic feet by 22.

Formerly, however, and to some extent at the present time, bricks were made of two sorts and sizes-common brick, 7 inches to 8 inches long by 44 inches wide and 2½ inches thick, and front brick, 4 inch longer and wider. Of common brick 20 are required to lay one cubic foot or 15 common brick will lay one square foot of wall 8 inches thick. Hence to estimate the number of bricks required for a wall 12 inches or more in thickness, multiply together the length, height, and thickness in feet, and that product by 20; or for an 8-inch wall multiply the length by the height and that by 15. An allowance of one half should be made for doors, windows, and other openings. Multiply their length by their width and that by the thickness of the wall in feet. Deduct one half the result from the cubic contents of the wall before multiplying by 20 or by 15, as above. DRY AND LIQUID MEASURE Dry Measure. -The standard unit of dry measure is the English or Winchester bushel, containing 2150.42 cubic inches or 77.627 pounds avoirdupois of distilled water at its greatest density. The standard measure is circular in form, its diameter inside being 18½ inches, and its depth 8 inches. Dry measure is used in measuring grain, coal, fruit, vegetables, etc. The following is a table of dry measure commonly used in the United States: gills. 2 pints. quarts. 3 quarts. 2 gallons.. 4 pks. or 8 gal. 8 bushels... 36 bushels.... 1 pt.343 cu. in. nearly. 1 qt. 69 cu. in. =69 1 gal.-2771 cu. in. 1 pk. .1 pk. 554½ cu. in. 1 bu. 21501 cu. in. .1 qr. = 101 cu. ft. nearly. ....1 chaldron.

When articles usually measured by the above table are sold by weight, the bushel is taken as the unit. The number of avoirdupois pounds in a bushel varies in different States and with different articles.

In measuring grain, seeds, or small fruit, the measure must be even or "stricken." In measuring large fruits or coarse vegetables, corn in the ear, etc., and also meal and bran, the measure should be heaped at least 6 inches.

Five stricken bushels are considered equal to 4 heaped bushels. The stricken bushel is now little used, except to ascertain capacities.

All the denominations are used in trade, the peck being the least in use. one pt. one gi.
