2. Of the Ash of Barley. A thousand pounds 

 of the grain of barley (two-rowed, Hordeum dis~ 

 tichon} leave 23 Ibs., and of the ripe dry straw 

 52-42 Ibs. of ash. This ash consists of 



3. Of the Ash of Oats. In 1000 Ibs. of the 

 grain of the oat are contained about 26 Ibs., 

 and of the dry straw about 57$ Ibs., of inorganic 

 matter, consisting of (see next column) 



4. Of the Ash of Rye. The weight of ash con- 

 tained in 1000 Ibs. of the grain of rye is 10^ Ibs., 

 and of the straw 28 Ibs. This ash consists of 



5. Of the Ash of Beans, Peas, and Vetches. The 

 ash of the seed and straw of the field bean, the 

 field pea, and the common vetch ( Vicia saliva), 

 dried in the air, contains in 1000 Ibs. the several 

 inorganic compounds in the following propor- 

 tions: 



6. The Ash of the Turnip, Carrot, Parsnip, and I from the field, contain respectively in 10,000 

 Potato. These 4 roots, as they are carried Ibs. 



7. Of the Ash of the Gh-asses and Clovers. The 

 following table might have been much en- 

 larged. I have thought it necessary, however, 

 to introduce in this place only those species 

 of grass and clover which are in most exten- 



sive use. I have also calculated the weights 

 given below for these plants in the state of hay 

 only, as the succulency of the grasses that is, 

 the quantity of water contained in the green 

 crop varies so much that no correct estimate
