lent quantity in each row. The plants were cut and weighed as rap- 
idly as the crop appeared to reach a uniform stage of ripening, 
which may be described for the maize as at the close of the pollen 
fall, and in the early milk of the ears; and as at bloom for the sorg- 
hum. 
For the purpose of determining the uniformity of yield, we have 
calculated the forage to the half-plat, and noted the difference be- 
tween the halves.

From this table we may note the close duplication between the 
two halves of each crop, the variation being in no case in excess of 
64 per cent. from the average. In ©. 13 and C. 14, Early Amber 
Cane, we have duplicate fertilization for four years, duplicate con- 
ditions this year, and very close duplication in results. In C. 10, 
C. 9, and C. 8, we have duplication in all but method of planting, 
and the results here show clearly that thickness of planting in- 
creased crop, as C. 9, 1530 lbs.; C. 10, thicker planting, 1736 lbs. ; 
C. 8, much thicker planting, 1900 lbs. ‘The evidence in favor of 
thicker planting can be readily separated from the table, thus :—

The next point to remark is that the Early Amber Cane yielded 
more forage than did the maize. This happened likewise in 1884. 
Four agricultural species of corn and one of sorghum were used 
this year. ‘The average yield of the various plats were :
