ANALYSIS OF THE CROPS RAISED ON THE THREE EXPERIMENTAL LOTS. 
Having given a full statement of the composition of the soil which was furnished from 
the three experimental acres, I now proceed to give the composition of the crops which 
were produced upon them respectively. The crop obtained was the common variety of 
oats, as usually seen in market, namely, a mixture of white and black oats. Nothing, 
however, has been stated respecting the variety. The samples of the oats were furnished 
in small bags properly labelled, and in small bundles with about eighteen inches of the 
upper part of the straw. The proportions of straw, grain and chaff, therefore, could not 
be determined. The proportions of water and inorganic matter were determined as the 
following statement will show :
