and become fixed or non-volatile. This acts 

 also as a disinfectant, purifying the air of the 

 stable. The sulphuric acid, the phosphoric 

 acid, and lime of the bone, being non-volatile, 

 are in the best condition to unite chemically 

 and mechanically with the volatile principles. 

 Each ingredient becomes available for plant 

 food. The whole mass is homogeneous, with 

 loss reduced to the minimum. 



By feeding for manure such articles as cot- 

 ton-seed, flaxseed, or oil-cake, shorts, or wheat- 

 bran, while they go to make up a perfect food 

 for the cow, producing a greater flow and 

 better quality of milk, also improving the 

 cattle in flesh, and giving them a fine, comely 

 appearance, it is also stated that more than 

 half their value goes through the cattle into 

 the manure pile. The chemists and the crops 

 seem also to prove it. The farmers ought 

 also to prove or disprove it in their way by 

 feeding a certain number of cows each with 

 and without these articles, carefully weighing 

 their alvine discharges and planting their ex- 

 periment plats in all other ways alike, then 

 adding half the grain rations to another por- 

 tion of the manure that does not contain the 

 grain rations, and again using half the grain 

 rations as fertilizer without any manure, also 

 .using a full grain ration without manure.
