TABLE VIII. 



Statements of Experiments continued with sixteen cows, from May 19 

 to June 8, for twenty days. 



Average daily flow of milk from the sixteen cows, in pounds and hundredths, . 20.75 

 Average number of days after calving, 134.69 



These sixteen cows were the same as in the last trial. Their feed was pasture grass only. They 

 increased their milk in 20 days, 853.86 pounds, or a fraction over 2.66 pounds daily for each cow. 

 Estimating pasture land at forty dollars the aero, and five acres to the cow, the cost of keeping 

 each cow would be the interest and taxes on five acres of land, valued at two hundred dollars. 



Interest on two hundred dollars one year, $12 00 



Taxes one year, 1 00 



Cost of keeping one cow half a year, $13 00 



Thirteen dollars divided by the number of days in half a year, gives 7.15 cents the day for keep- 

 ing one cow, aud $22.88 for sixteen cows 20 days. 



These sixteen cows gave, in 20 days, 6,640.03 pounds of milk, which cost 3.46 cents the gallon of 

 ten pounds. 



The gain in weight, in this trial of sixteen cows, was 484 pounds.
