ANALYSES OF BARLEY. 



2. Analysis of the ash of the grain. 



Calculating that an acre will yield 30 bushels, and that a bushel weighs 50 lbs., there will 

 be removed from it the following amounts of the elements, taking the foregoing analysis 



as correct : 



In Silica 12-855 lbs. 



Phosphates 31-148 



Potash 6-493 



Soda V 2-948 



63-449 lbs. 



It will be observed that this barley differs somewhat in composition from that grown in 

 the Wheat district of this State ; but as the analyses which have as yet been made are few, 

 it will not be safe to make generalizations from them. Barley is regarded as a lime plant, 

 when compared with wheat. The lime and magnesia, in this last analysis, seem to be 

 combined entirely with phosphoric acid, as usually is the case in wheat. 



3. Analysis of the straw and chaff. 

 Percentage of ash, 5-00.

 Phosphates 

 Lime 

 Magnesia 

 Potash - 

 Soda 



Sulphuric acid 

 Chlorine 



The amount of silica is increased by the mixture of the chaff with the straw : the chaff 

 (piven 5^ per centum of ash, the straw about 4.
