ter, and 40 pounds gives us one and one-quarter pounds. We 

 double the food, and get^ue times the amount of butter. If we 

 could get the cow to eat and turn into butter 60 pounds of hay 

 a day, we should get two and one-quarter pounds of butter per 

 day. In other words, three times the food would give us nine 

 times the amount of butter. If the cow had sufficient capacity 

 to eat and turn into butter 80 pounds of hay per day, she would 

 give three and one-quarter pounds of butter per day. In this 

 case we feed four times the amount of food, and get thirteen times 

 the amount of butter. 



"To put the matter in another light, suppose a farmer has 

 5 1 tons of hay. If he fed it to cows at the rate of 15 pounds 

 per cow per day, it would be nearly enough for twenty cows for 

 one year. From these, on the basis supposed, he would get 

 nothing. He would lose aU his feed, (except manure,) all his 

 time and labor, all the interest on the money invested in the cows, 

 and probably some of the principal. 



''If he fed 20 pounds per day, he could keep sixteen cows a 

 year. These would give him 28 pounds of butter per week. 



"If he fed 40 pounds, he could keep eight cows a year, and 

 these would give him 70 pounds of butter a week. 



"If he fed 64 pounds per day, he could keep five cows a year, 

 and these would give him 86 pounds of butter per week. 



"In other words, reckoning the season at 40 weeks, the 54 

 tons of hay when fed to 



20 cows, gives None. 



16 cows, " 1520 pounds. 



8 cows, gives 2800 pounds. 

 5 cows, " 3420 " 



"Now, if we could get our cows to eat 64 pounds of hay a 

 day, or even 40 pounds good clover hay, at the prices named, it 

 w^ould be by far the cheapest food we could use. But this can- 

 not be done ; the digestive organs of the cow are not powerful 

 enough. But we can get a cow to eat 40, 50 or 60 pounds of 

 hay equivalent. "We do this by feeding in conjunction with hay 

 or roots, corn meal, oil cake or other food containing a large
