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:

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.

The amount of silica is increased by the mixture of the chaff with the straw : the chaff 
gives 5^ per centum of ash, the straw about 4.
