fouitli feet from the gruuiul or two ;md one-fourth pounds one foot 

 from the ground. In order to have the protein, carbhydrates and fat, 

 if one pound of fat were burned it would lift one pound two and one- 

 fourth feet, and add this in-oduct to the amount of carbhydrates and 

 divide the sum obtained, by the protein. The quotient will be the 

 ratio. In the above ration there is .J)4 pound of fat. This multi- 

 plied by 2^ equals 2.12 pounds; add to this amount the 11.05 pounds 

 of carbhydrates and we have 13.17 pounds. Divide this amount by 

 2.24 (the amount of protein), and we get a quotient of 5.9, which 

 equals the ratio of 1:5.9. That is to say, there is one pound of protein 

 or milk and muscle forming food to 5.9 i)ounds of carbhydrates and 

 fat or heat and fat forming foods. 



AVERAGE PENNSYLVANIA PRICES FOR FEEDING STUFFS. 



In a subjoined table is given as near as possible the average selling 

 price of the different feeding stutTs for the past ten years. It was 

 next to impossible to get figures for so long a time on some of the 

 feeds. In these cases the present prices were taken. The cost of 

 all the rations are based on the figures given in this table; in the case 

 of hay, corn stover and other products of the farm the prices given 

 are somewhat below the market price, and in the case of the by- 

 products that have to be brought, the prices given are slightly higher 

 than the market price. This was done in order to make allowance 

 for the expense of hauling to or from the farm :
