The amount of manure produced annually has been estimated as 

 follows, for a 1,000 pound ox: 



Phosphoric 

 Nitrogen. acid. Potash. 



Solid manure, 20,000 lbs. containing .. 96.4 46.6 96.0 



Liquid '' 10,000 ^' .. 95.5 160 9 



Total per year 191.9 46.6 256.9 



At the prices usually placed upon nitrogen, phosphoric acid and 

 potash, the liquid manure would be worth S23.95, and the solid 

 $23.01, a total of $46.96, provided it could be saved, but owing to 

 the ease with which urine decomposes, there is great difficulty in 

 saving the nitrogen in the liquid manure, and if we remember that 

 $16.71 of the value of the total manure, or thirty-five per cent is in 

 the form of nitrogen in the urine, it at once becomes evident that 

 farmers should take every precaution to save this element. 



Those who draw their farm yard manures, liquids and all, and 

 spread them on the land as fast as produced, without doubt handle 

 the urine with the least waste. Next to this the use of a liberal
