guano,
ground bones, and manure from the barn yard; and the ultimate profit to
be derived from each, in a full rotation. After the first crop of grass,
and perhaps the second, which was in favor of the manured portion, the
succeeding crops of hay and clover seed, have been decidedly better on
the boned part of the field. At the present time, and also the past
season, this being the fourth year in grass, the guanoed lands present
about the same appearance, that does a small adjoining space, purposely
left without manure of any kind, lime excepted. The manured part affords
good pasture, but is quite inferior to the boned, which would give a
fair crop of hay, and probably three times as much grass as the two
lands with guano. It is believed that the increased crop of clover seed
on the boned, over the guanoed portion, paid for the former; and that
the two crops of clover since taken from the field, have paid, or nearly
so, for the lime or other manures applied.

This evidence corresponds with the opinion of Professor Mapes; that is,
that the value of an application of guano is greatly enhanced by the
addition of phosphate of lime, in some shape; the guano acting
immediately and producing a direct profit, while the slow action, for
which some farmers cannot wait, keeps up the fertility for years, or
until the owner may find time to profit by another application of guano.

We quote again a few more of the very sensible remarks of friend
Stabler. "I am an advocate for the liberal use of all kinds of manure,
guano included, if the price will justify it. A farmer had better buy
manure than to buy grain, if compelled to do either; for we cannot
expect much from nothing, or reasonably calculate upon improving very
poor land without manure of some description, unless plaster will act
with effect; nor is this generally the case without the land possesses
naturally, some particular source of fertility, not wholly exhausted by
bad or improvident tillage.

"It is probable those will be disappointed who expect to do everything
with guano--make fine crops and improve the land, while they take
everything off, and dispense almost, if not entirely, with the more
permanent manures, all equally within their reach. True, we may exist
for a time, only half fed and half clothed; but it is just as reasonable
to expect to improve under such a regimen, as to calculate upon
continued, not to say increased fertility of the soil, without an ample
