included in the general averages. No attempt is made, there- 
fore, to draw conclusions concerning the effects of the fertilizers 
from the experiments of that year. 
The experiments of 1895 and 1896 indicate, in brief, that as 
regards both yield and composition the nitrogenous fertilizers 
benefited greatly both the corn and the stover in the two 
varieties. ‘The yields from the plots with nitrogenous fertilizers 
were considerably larger than those from the plots which had 
the mineral fertilizers only or no fertilizers at all. The pro- 
portion of protein in the crops was higher where nitrogen was 
used in the fertilizer, although the percentage of protein did 
not increase in proportion to the amount of nitrogen used: 
The percentage of protein in the seed taken from the 1896 
crops for planting in 1897 was not so large in either variety as 
was found in the original seed planted in 1895; the average 
composition of the grain of each variety from all the plots 
showing only 11 per cent. of protein in the white flint in the 
latter season, as against 13 per cent. in the original sample; 
and the yellow flint 10.2 per cent. in the latter season as against 
II per cent. in the original sample. The experiment with the 
two varieties was not continued long enough, however, to draw 
any conclusions from these results regarding the relative ten- 
dencies to maintain, increase or diminish their percentages of 
nitrogen under the different methods of fertilizing. 
Inasmuch as for lack of proper seed the experiment with 
yellow flint corn could not be continued, a new lot of white 
flint corn was obtained in 1898 from the grower who had fur- 
nished the seed of this variety in 1895, and this new lot of seed 
was planted on the sections (Series A) previously devoted to 
yellow flint corn, and since that time only the one variety— 
white flint—has been used in these experiments with corn. 
The sections (Series I’) at the south end of the field, however, 
were planted with seed grown on the same sections jn the pre- 
ceding year. There was, therefore, a difference in the con- 
ditions under which the two lots of seed had been grown 
prior to 1898. Furthermore, a difference was made in the 
fertilizing of the two series (A and F), as explained in the 
next paragraph; lime being applied on Series A in addition to 
the regular fertilizers, while on Series F no lime was applied in 
addition. For these reasons it was thought best to keep the data 
from the two series separate, as is done in Tables 37 and 38.
