72 ESTIMATION OF CROPS IN THE BULK 



7. How many bushels of ear corn will a wagon bed that 

 is 10 ft. long, 3 ft. wide, and 26 in. deep hold ? 



8. How many bushels of corn in the husk will the crib 

 at home hold? How many bushels of corn on the cob will 



it hold? 



HAY 



81 . A ton of packed timothy hay contains about 450 cu. ft. ; 

 a ton of clover, alfalfa, or cowpea hay, about 550 cu. ft. 



82. The capacity of a hayloft in tons equals the product 

 of the length, width, and height in feet, divided by 450 for 

 timothy hay, and by 550 for clover hay. 



83. Rule. To find the approximate number of tons in a 

 stack, square j of the distance around the stack, measured at 

 a point halfway from the ground to the top ; multiply this by 

 the height of the stack in feet, and divide by 450 if timothy 

 hay ; by 550 if clover, alfalfa, or cowpea hay. For ricks : Meas- 

 ure over the rick, from the ground on one side to the ground on 

 opposite side ; also the ividth of stack near the ground. Add 

 the over measure and the width together ; divide by 4; square 

 the result and 'multiply by the length of rick ; then divide by 

 450 if timothy ; by 550 if clover, alfalfa, or cowpea hay. 



EXERCISE 



1. How many tons of timothy hay are there in a loft 

 30 ft. long, 24 ft. wide, with an average depth of 7 ft. ? 



2. Measure and estimate the number of tons of timothy 

 hay that your barn will hold. 



3. How many tons of clover hay can be stored in a place 

 15 ft. long, 12 ft. wide, and 6 ft. deep? 



4. Measure a number of haystacks in your neighborhood 

 and estimate the approximate number of tons in each stack. 



5. Measure one of your father's or neighbor's haystacks 

 and estimate its worth at the local price of hay.
