Evans' Millwright and Miller's Guide, Chap. 2, p. 47. RULE. Multiply the length by the width at top, and that product by one third of the depth, divide the last product by 2150.4, if you calculate by inches, or by 1.24444 if you work by feet; the quotient will be the contents in bushels To make a Hopper to hold any given quantity, having the depth given. RULE. Divide the inches contained in the bushels it is to hold, by one third of the depth in inches; the quotient will be the square of one of the sides at top. Extract the root of that square for the length of one side. EXAMPLE 52. The hopper shall hold 6.5625 bushels, the given depth is 24 inches, how long must be one side at top? Ans. 42 inches. Evans, p. 48. OPERATION. 262500 3281250 65625 131250 One third the depth = 8)14112.00000 v 1764.(42 Ans. in inches. 16 82). 164 164 OF A GARNER OR BIN. On the 5th of March, 1816, an old jockey bet that a bin 3.5 feet square and 3 feet high would hold 30 bushels; a young industrious man bet it would not hold so much : after calculating the contents, the jockey refused to pay the bet because he could pile on 30 bushels : pray how much did the bin hold without any prevarication ? Answer, 29 bush. 16 qts. 7.9+ gills. One bushel = 1.24444 foot for a divisor. One side of the bin 3.5 feet * 3.5 = 12.25 x 3 the height = 36.75 feet for a dividend. 1.24444)36.75000(29.531 B. 248888 . 44236 To make a Garner, Bin, or Box, that shall hold any given quantity, having two of its sides given, take the following RULE. Multiply the contents of one bushel by the number of bushels the bin is to hold, for a dividend; then multiply the given sides into each other for a divisor, the quotient will be the length of the side wanting. EXAMPLE 53. Given, two sides of a garner 6.25 by 10.5 feet; required, the other side, to hold 184.6 bushels. Evans, p. 47. EXPLANATION. One side 6.25 X 10.5 = 65.625 for a divisor; 1.24444 the eontents of a bushel x 184.6 the quantity in bushels = 229.723624 = 65.625= 3.5 feet for the side required. 54.
