A cubic foot of water weighs 62^ pounds, and contains 1,728cubic inches, or 7^ gallons. A gallon of fresh water weighs 81-3 pounds, and contains 231cubic inches. To find the capacity of a cylinder in gallons: Multiply thearea in inches by the height of stroke in inches. Divide this prod-uct by 231 (being the cubical contents of a gallon in inches) ;the quotient is the capacity in gallons. :206 HARDENING, TEMPERING AND ANNEALING. To find the area of a circle or cylinder: Square the diameterin inches and multiply the product by .7854. Example : What is the area of a 12-inch circle? i2Xi2^i44+.78S4=i square inches. Rust joint cement (quick setting) : i part sal-ammoniac inpowder (by weight), 2 flour of
