fertilizers as the larger plots had received in the earlier experi- 
ments on grass. ‘The plan of the experiment was to have a 
series of ten plots, two to be cropped without fertilizers, eight 
to have a fixed quantity in each case of mixed minerals—dis- 
solved bone-black and muriate of potash. Of the eight fertil- 
ized plots, six wére to receive different kinds and amounts of 
nitrogen. On three of these the nitrogen was applied in the 
form of nitrate of soda, supplying nitrogen at the rate of 25, 
50 and 75 pounds per acre, and the other three were supplied 
with sulphate of ammonia furnishing nitrogen at the rate of 
25, 50 and 75 pounds per acre. 
Owing to the smallness of the plots it cannot be expected 
that the experiment will prove as valuable as regards the effect 
of fertilizers on yields as might be obtained on larger plots. 
It was thought, however, that the most important part of the 
experiment would be the effects of fertilizers on composition, 
and that the results would be nearly as valuable from smaller 
plots as from larger, and a greater number of crops could thus 
be experimented upon. 
EHXPERIMENTS ON CORN. 
For the purpose of studying the effects of fertilizers and of 
breeding on the composition of corn, two varieties, differing 
quite widely in composition, were chosen. In one variety the 
seed used contained relatively large quantities of protein, 13.0 
per cent. in the dry matter, while the other variety was known 
as poor land corn, and contained relatively small quantities of 
protein; 11.2 pericent.in the dry matter; It is plannedwte 
grow these two varieties on similar plots of ground through a 
series of years, using the same fertilizers from year to year, 
and to save seed from each plot and plant it again on the same 
plot the following year. It will be noticed that the crop on 
two plots is grown entirely without fertilizers, on two more 
with only mineral fertilizers, and on the other six with dif- 
ferent amounts of nitrogen, varying from 25 to 75 pounds per 
acre. ‘The two varieties were planted at opposite ends of the 
field, and as one was about ten days earlier than the other, it 
was thought that the seed would not mix. A slight amount 
of mixing did occur, however, but it is hoped that this condi- 
tion may be avoided another season by planting one variety 
early and the other late. ,
