530 COMPUTATION TABLES 



There are about 5000 honey-bees in a pound. 



Watermelons are usually sorted into three grades. Of the largest 

 size, about six melons are placed in a barrel. Of medium size, about 

 eight (four melons in each of two layers), and of the smallest size, ten 

 to twelve. A truck-load of melons comprises about 200 fair-sized 

 fruits. A car-load numbers 1000 to 1500. 



Coconuts are packed for shipment in bags which hold 100. 



" Ekimis " branded upon boxes of Smyrna figs means A. No. 1, 

 or Superior Selected. " Eleme " means Selected, the second grade. 



A box 12^| in. long, wide, and deep holds 1 bu. 

 A box 19f in. long, wide, and deep holds 1 bbl. 

 A box 8| in. long, wide, and deep holds 1 pk. 

 A box 6 r 7 ff in. long, wide, and deep holds \ pk. 

 A box 4^ in. long, wide, and deep holds 1 qt. 



To find the bushels of apples, potatoes, shelled corn, etc., in bins, 

 divide the cubic contents in inches by 2747.7 (the cubic inches in a 

 heaped bushel). If the corn is in the ear, deduct one-third from the 

 result. 



The cubic contents is found by multiplying together length, 

 breadth, and height in feet, and reducing the product to inches by 

 dividing by 1728 (the number of cubic inches in a cubic foot) ; or 

 make the original multiplication in inches rather than in feet. 



A struck bushel (not heaped) contains 2150.4 cubic inches. See 

 p. 528. 



If the sides of a corn-crib are flaring, it is customary to reckon 

 the width as half the sum of the top and bottom widths. Of course, 

 much will depend on how much it flares. A similar method may be 

 applied to apples, potatoes, and roots in heaps. 



To find the tons of hay in a mow or stack, divide the cubic contents 

 by about 500, if the hay is not well settled ; or by about 450 to 460, 

 if the hay is well packed. 



To figure the cost of hay by the ton, multiply the number of pounds 

 by the price (in dollars) per ton, point off three figures at the right, 

 and divide by 2 (point off more figures if there are fractions of a 

 dollar in the price) : 



96 Ib. X $ 11 ton = 1.056 - 2 = .528 (52 r " ff cents). 



96" X$ 11.30 " = 1.0848 2= .54. 



1700 "X $13 " =22.100 2 = $11.05. 



2100 "X $18 " =37.800 - 2 = $ 18.90. 



3350 "X $10.80 " =36.180 : s- 2 = $ 18.09.
