127. Dry Measure. The common table of dry measure is as follows: A bushel, as we have learned, contains 2150.42 cu. in., or about 1 cu. ft. A dry quart contains 67.2 cu. in., while the liquid quart contains only 57.75 cu. in. In measuring grain, seeds, and small fruits the measure must be even full. In measuring apples, potatoes, and other large articles the measure must be heaping full. The various states prescribe the weight of certain farm products per bushel. Some of these weights have been given on page 125. 58. 1952 qt. 60. 6336 pt. 54. 516 pk. 56. 956 pk. 61. A bushel contains 2150.42 cu. in.

There are 231 cu. in. in a gallon and 537.6 cu. in. in a peck. From these measures verify the number of cubic inches in a liquid quart and in a dry quart as given in § 127 below the table. 128. Liquid Measure. The common table of liquid measure is as follows: These measures also are in common use: 31 gallons = 1 barrel (bbl.) Casks holding from 28 gal. to 43 gal. are called barrels, and casks holding from 54 gal. to 63 gal. are called hogsheads. Whenever barrels or hogsheads are used as measures, a barrel means 31 gallons, and a hogshead means 63 gallons. A barrel contains about 43 cu. ft. A gallon of water weighs about 8.3 lb., and contains 231 cu. in. Reduce to quarts: 21. 792 gi. 22. 298 pt. 23. 9263 gal. 24. 72 gal. 3 qt.
