The litter used at the experimental farm at Bechelbronn, was wheat 

 straw, which usually contains twenty-six per cent, of moisture. The 

 following analysis shows what it is composed of: 



Carbon, 25.8 



Hydrogen, . 3.9 



Oxygen, 28.8 



Azote, 3 



Salts and earths, 5.2 



Water, 26.0

In the same estahlishment, moist farm-yard dung was found to con- 

 sist of: 



Carbon, 7.41 



Hydrogen, 0.87 



Oxygen, 5.34 



Azote, 0.41 



Salts and earths, 6.67

These tables are exceedingly interesting, as by their aid we are en- 

 abled to understand the composition of this valuable manure, and to 

 know the reasons why it has such a powerful effect in promoting vege- 

 tation. By examining the ashes of plants, we discover the mineral in- 

 gredients upon which they live. The following tables made by Dr. 

 Antisell, show analysis of the ashes of plants : 



Potatoes. Turnips. Clover. Wheat. W. Straw.
