manure from the 1000 lbs. of cotton-cake ; and the other received 
artificial manure supplying the whole of the nitrogen and other 
constituents estimated to be contained in the manure from the 
1000 lbs. of maize-meal. There was a fairly regular plant on 
all the four acres. Gaps in the rows here and there were filled 
up by transplanted roots, which grew fairly well, but did not 
nearly attain the dimensions of the roots not checked in their 
growth by transplanting.
