168 BOAED OF AGRICULTURE. 



a single cow, being only an average producer of dung, was 

 selected from the fifty cows usually kept at the establishment. 

 She was fed as usual, and as the other cows were. The food 

 and water was weighed for seven days. She consumed in 

 this period, — 



Water, . . . . . .612 pounds. 



Potatoes, . . . . . . 87 " 



Hay, 167 " ' 



A total of 866 pounds food and drink, and voided, free from 

 her liquid evacuations, 599 pounds of dung ; a cord of it, pure 

 as dropped, would weigh 9,289 poimds. 



Estimating for twelve months, a cow would consume, — 



Of Water, 31,824 pounds, 

 Potatoes, 2,262 " . 

 Hay, 4,342 " . 



Pasture, six months. 

 Labor and care, 10 cents per day, . 



Estimated cost of keeping cow one year, $106 23 



The products, estimating the same quantity of dung from 

 the pasture as from the other feed, Avould be, — 



' Calf, $5 00 



2,500 qts. of milk at 3 cts. per qt., . . 75 00 

 Cost of dung (31,145 pounds, if all saved), 



to balance, ...... 26 23* 



When milk is converted into butter and cheese, it takes 

 about fourteen quarts of milk to make one pound of butter, 

 the average price of which is twenty-two cents per pound. 

 Fourteen quarts of milk to three pounds cheese, average price 

 nine and three-quarter cents per pound, thus netting about 

 two cents per quart for milk. 



These estimates each Avill form, according to circumstances, 

 demand for milk, difference and cost in feed and quantity fed. 

 Each should estimate according as he is situated ; but cost, 

 quality and value should be known, or at least approximated 



* Its value, by the table, would be but ^15.63.
