EXPERIMENTS ON COW PEAS. 
On two series of plots of one-fiftieth of an acre each, similar 
to those on which the corn was grown, cow peas were planted. 
The results obtained on the two sets of plots were added 
together and are reported as one experiment. The kinds and 
amounts of fertilizers per plot were exactly the same as on the 
corn plots. The seed was planted in drills, June 5th, at the 
rate of about one bushel per acre. In this experiment it is 
impossible to use the seed of the crop of the year before, as the 
cow peas do not mature seed in this climate. ‘The seed has 
been obtained each year from Tennessee. It will be noticed 
from the table which follows that there was a large increase in 
yield on the mixed mineral plots (6a and 60) over that obtained 
on the nothing plots, and that in the case of the nitrate of soda 
plots, 7, 8 and 9, there was quite an increase over that obtained 
from mineral fertilizers alone. "The increase derived from the 
use of nitrogen was not very marked, however, as it will be
