fourth feet from the groimd or two and one-fourth pounds one foot 



from the ground. In order to have the protein, carbohydrates and 

 fat; if one pound of fat were burned iL would lift one pound two 



and one-fourth feet, and add this product to the amount of carbohy- 

 drates and divide the sum obtained, by the protein. The quotient 

 will be the ratio. In the above ration there is .94 pound of fat. 

 This multiplied by 2^ equals 2.12 pounds; add to this amount the 

 11.05 pounds of carbohydrates 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 pounds of 

 carbohydrates 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 sell- 

 ing price of the different feeding stuffs for the past ten years. It

 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 

 tlic by-products that have to be bought, the prices are slightly 

 higlier than the market price. This was done in order to make al- 

 lowance for the expense of hauling to or from the farm:
