showing, in the actual returns, the full advantage that 
decorticated cotton cake would otherwise have given. The 
barley was cut on August 26, carted on September 4, after 
having to be “ opened out ” again in order to dry it. The 
produce was threshed on November 2, and the results are 
given in Table VIII.

It will be seen that plot 1 (decorticated cotton cake) gave 
the highest yield, though, as explained, this would have been 
much higher but for the damage that the barley received from 
the storms near harvest time. The produce of plot 2 (maize 
meal), on the contrary, was rather less than that of the 
unmanured plots. The differences are shown thus : —

The quality of the barley of plot 1 was, as was to be 
expected, inferior to that of the other plots ; it was valued at 
24s. 6d. per quarter on a basis of 28s. for the season, the other 
plots being put at 25s. 6d. and 26s. All the barley was more 
or less spoilt by the weather. The land was ploughed after 
the barley crop, cultivated through the spring of 1906, and, 
on March 26-28, 2 tons per acre of lime were spread on it. 
On June 14, white mustard seed was drilled in, and gave a good 
plant. The mustard crop was cut, carried, and weighed green
