 the account their improved condition and capability 

 for work. A horse fed on potatoes should have his 

 quantity of water materially curtailed. 



Prof. Low says that fifteen pounds of potatoes yield 

 as much nourishment as four pounds and a half of oats. 

 Von Thayer asserts that three bushels are equal to 112 

 pounds of hay ; and Curwen, who tried potatoes ex- 

 tensively in the feeding of horses, says that an acre 

 goes as far as four acres of hay.

 brook, and drink their fill, and no harm results, for 

 they obtain that kind of water which nature designed

 one. In soft water, soap will curdle, vegetables will 

 not boil soft, and the saccharine matter of the malt can- 

 not be fully obtained in the process of brewing. There 

 is nothing in which the different effect of hard and soft
