COMPOSITION OF MANURES. 97 



the abundance and richness of the food furnished them. 

 The following table is compiled from experiments and 

 analyses made at Cornell University, and there is no doubt 

 that the stock was well fed. 



COMPOSITION AND VALUE OF FRESH MANURE 

 FROM DIFFERENT ANIMALS. 

 Phosphoric 



The value is figured at the price agreed upon by east- 

 ern chemists as fair value for the ingredients as used in 

 artificial fertilizers. 



Value per ton is also conditioned upon the percentage 

 of water in the manure. Hen manure has much less water 

 even in a fresh state than that of cattle, and air-dried hen 

 manure, free from earth, etc., is sometimes worth as much 

 as $10 per ton, providing the hens are well fed. In this 

 State air-dried sheep manure in large corral deposits in 

 Fresno has been found by analyses at the University of 

 California to have this composition and value : 



Per cent. 



Nitrogen 2.32 



Potash 2.90 



Phosphoric Acid 2.88 



The material had only twenty-eight per cent of water 

 and its value calculated at the agreed price of its ingre- 

 dients is $10.95 per ton. Even when calculated at the 

 same per cent of water, the California corral deposit has 

 much higher value than the eastern sheep manure. 



Garden Use of Concentrated Manures. Hen, sheep, and 

 hog manure are very much richer, as shown, than the
