170 AMERICAN MANURES. 



saves in the cost of transportation and labor of 

 applying, as well as presents the valuable salts 

 in soluble form, directly available for the wants 

 of the plant to give it a vigorous and healthy 

 start ; while plants manured with unfermented, 

 unrotted manure, are deprived of what they 

 need until these operations have taken place in 

 the soil. Oftentimes by this cause they are so 

 stunted in the beginning, that no subsequent 

 application will make amends for the injury 

 then done. 



We shall now give the value of the urine of 

 different animals, as shown by the fertilizing 

 salts contained in 1000 Ibs. of each : 



Water. Phosphoric Acid. Potash. Nitrogen. = Ammonia. 



Pig Urine, 9'291bs. trace, 6-0 Ibs. 11.8 Ibs. = 14-3 Ibs. 



Horse " 9-40 " trace, 2-8 " 15-4 " = 18'7 " 



Cow " 9-23 " trace, 4-5 " 4-4 " = 5-3 " 



Sheep " 9-65" 1-3 Ibs. 7-2" 13-1" =15-9" 



Human " 9'57 " 4-0 " 2'0 " 14-2 " == 17-2 " 



The following Table shows the amount pro- 

 duced annually by a single animal of the kind 

 named, and its value as manure, when fermen-
