*About one-fourth of Plot 6 pulled up by crows. 



Average of nothings 27.5 bushels of hard corn ; 5.1 bushels of soft 

 corn and 1880 pounds of stover. 



The ncre for this experiment is on the old alluvial soil of the 

 Connecticut valley. The field has a very slight slope south and west 

 and is of such form that the arrangement of plots adopted was 

 different fiom that followed in the other experiments. The plots 

 were in two series, in each 150 feet long, and five rows in each. 

 There were seven plots in each series and four in place of the usual 

 five nothing plots. In each series the plots were numbered from the 

 east side ; the first in one series being No. 1 and in the other No. 8. 

 It will thus be seen that the nothing plots in the different series were 

 not opposite eacii otlier. The field had been in grass without manure 

 for the past five years, and had been pastured the preceding year. 



The soil is a fine yellow loam, underlaid, at the depth of a few feet 

 by gravel or sand, and with perfect natural drainage. It proved to 

 vary to a considerable degree in natural fertility in the two series ; 

 but such are the methods of comparison adopted that it is not believed
