as valuable, or even more valuable, than the dung ; but impor- 

 tant considerations come in to dispel this illusion. A com- 

 plete analysis gave, as contained in each ton of the fresh 

 dung, the following amounts of valuable constituents : — 



POUNDS. 



Nitrogen 5.11 



Phosphoric acid 3.55 



Potash 2.00 



The nitrogen in manure has a higher value than that in 

 muck ; but estimating it the same, with the phosphoric acid, 

 potash, etc., the value stands as follows : — 



^iV pounds of nitrogen, at 15 cents .... ^.76 



3^ pounds of phosphoric acid, at 12 cents . . . .42 



2 pounds of potash, at 7 cents 14 



Lime and other salts 33

ANALYSIS 'OF LIQUID EXCREMENT. 



The nitrogenous and mineral value of muck stands to 

 fresh cow-dung as seventy-eight cents to a dollar and sixty- 

 five cents per ton, water-soaked, or nearly three to one in 

 favor of the latter; but it must be remembered that fresh 

 cattle-droppings do not represent manure as found in farmers' 

 barn-cellars. This consists of a mixture of the liquid excre- 

 ment with the solid. A ton of fresh urine, as determined in 

 analysis from specimens collected at my barn, gave the fol- 

 lowing results : — 



POUNDS. 



Nitrogen 17.50 



Phosphoric acid 10.12 



Potash 15.90 



This result indicates the very high value of liquid ma- 

 nures, giving a value per ton of about five dollars, the esti- 

 mate beino- made in accordance with that for muck and for 

 solid excrement. A ton of well-mixed manure, containing 

 equal proportions of the solids and liquids, has a money- 

 value of not far from four dollars ; or this is the value of 

 the manure stored in the barn-cellar at Winnekeni Farm, as 

 learned from analysis.
