COST OF GROWING WHEAT 



76. The improved machinery now used for planting and 

 harvesting wheat has greatly reduced the expense of grow- 

 ing wheat. 



EXERCISE 



1. Estimate the cost of growing a 20-acre field of wheat 

 when (1) a man with a two-horse plow can break 2 A. per 

 day ; (2) a man with a three-horse harrow can harrow 15 A. 

 per day ; (3) a man with a three-horse roller can roll 12 A. 

 per day ; (4) a man with a two-horse drill can drill 10 A. per 

 day ; (5) the seed per acre is worth $1.50 ; (6) the land is 

 harrowed twice and rolled once ; (7) a man with a team is 

 paid $3 per day ; (8) the cost of fertilizing each acre is $1.50 ; 



(9) the cost of putting the wheat in the shock is $1 per acre ; 



(10) the cost of threshing the wheat is 60 per bushel. 



2. The yield being 20 bu. per acre, what was the cost per 

 bushel to grow the wheat in the above problem ? 



3. Using 10 men 3 da. at $1.50 per day and 45 bu. coal 

 at 150 per bushel, estimate the cost of threshing 800 bu. 

 wheat @ 40 per bushel, 1000 bu. oats @ 20 per bushel, 200 bu. 

 flax @ 80 per bushel, 100 bu. timothy @ 200 per bushel. 



COST OF GROWING COTTON 



77. Cotton is a staple crop of the South. It is valuable 

 both for the lint and the seed it yields. 



EXERCISE 



1. If a 20-acre field yields 840 Ib. of seed cotton per 

 acre and this cotton when ginned yields 40% lint, what is 

 the seed worth at 900 per hundred and the cotton at $54 per 

 bale of 500 Ib. each, the weight of the bale including 20 Ib 

 for bagging and ties ?
