the largest crop; but at harvest, it was found that it produced no
more corn than plaster. These results seem to indicate, that
superphosphate of lime stimulates the growth of stalks and leaves, and
has little effect in increasing the production of seed. In raising
Indian corn, for fodder or for soiling purposes, superphosphate of lime
may be beneficial, as well as in growing the sorghum for sugar-making
purposes, or for fodder--though, perhaps, not for seed."

"In addition to the experiments given above, I also made the same
season, on an adjoining field, another set of experiments on Indian
corn, the results of which are given below.

"The land on which these experiments were made, is of a somewhat firmer
texture than that on which the other set of experiments was made. It is
situated about a mile from the barn-yard, and on this account, has
seldom, if ever been manured. It has been cultivated for many years with
ordinary farm crops. It was plowed early in the spring, and it was
harrowed until quite mellow. The corn was planted May 30, 1857. Each
experiment occupied one-tenth of an acre, consisting of 4 rows 3-1/2
feet apart, and the same distance between the hills in the rows, with
one row without manure between each experimental plot.

"The manure was applied in the hill, in the same manner as in the first
set of experiments.

"The barnyard-manure was well-rotted, and consisted principally of
cow-dung with a little horse-dung. Twenty two-horse wagon loads of this
was applied per acre, and each load would probably weigh about one ton.
It was put in the hill and covered with soil, and the seed then planted
on the top.

"The following table gives the results of the experiments:
