is has been fully proved in a hundred
cases, since Mr. Stabler tried his experiments; for two years after, in
writing upon the same subject, he says "Harrowing in the guano with the
wheat will generally produce a better crop; but its fertilizing
properties are more evanescent. I prefer plowing it in for all field
crops; and when attainable, would always use it in conjunction with
ground bones, for the benefit of succeeding grass crops. This is
pre-supposing that you determine to improve more land than the resources
of the farm will accomplish, and are willing to do it by the aid of
foreign manures; and being 'far removed from lime.' If the object is to
realize the most in a single crop, and to obtain the quickest return for
the outlay, use the guano alone, and harrow it in with the wheat; but
the land, according to my experience, will derive but little benefit
from the application, unless the amount is large. By plowing it in,
particularly if mixed with one third its bulk of plaster, the effect is
decidedly more durable; nor is it then necessary that the seeding should
so immediately follow its application. If, however, the object is to
improve the land at the same time; and surely it should be a primary
object with every tiller of the soil--and lime, from your location, or
the price, is unattainable, I would advise about half the amount
determined on, to be expended for ground bones. This may be harrowed in
with the wheat."

It is surprising what an effect a few bushels of ground bones to the
acre will produce; reference is made to a single experiment, and not an
isolated one either. Some six years since, we applied ten to twelve
bushels of coarsely ground bones to the acre, on about half of a twelve
acre field; on two lands adjoining, was guano, at the rate of 200 pounds
to the acre, (the cost of each about the same,) and extending nearly
through the field; both were applied in the spring, on the oat crop--and
which was decidedly better, by the eye, on the two lands with guano. In
the fall, the field was sown with wheat, manuring heavily from the barn
yard, adjoining the guano, but not spread on the two lands, or on the
boned portion of the field.

There was but little difference perceived in the wheat, except from the
manure, which was the best--the field having been limed for the
preceding corn crop, 80 bushels to the acre. The experiment was made to
test the comparative durability of the three kinds of manure; the
