you must sow while the
wind is blowing, mix earth enough with guano to prevent blowing away.

_Depth it should be plowed in._--On light sandy land, there is no danger
of its ever being plowed in too deep. On sandy loam, it ought to be
plowed under at least six inches--eight inches would be better. On true
loam, a less depth will answer, though we are strong advocates of deep
plowing. On clayey loam, four inches will answer, and on clay,
particularly in the Northern States, if well harrowed or put in with the
cultivator, there will be no great loss of ammonia, as the clay is a
great absorber of that volatile substance. This rule may in general be
observed; upon the light lands of the south, it cannot be too deeply
buried; in the clay lands, or in the more heavy, cold, or moist lands of
the north, it may be covered too deep to benefit the first crop; but, if
the after cultivation is good, whatever is planted will be sure to be
benefitted. Upon granite soils, it will be of less value than silicious
or aluminous ones. Though most valuable on poor sandy or worn out old
fields like those of Virginia, already described, still it must not be
rejected by the owner of any land which can be improved by manure,
because this is a manure of the very best and most concentrated kind;
containing more of the ingredients necessary to promote vegetable
growth, in the exact proportion and combination, ready prepared for use,
than any other substance in the known world. It is a fertilizing
substance which none will reject who once learn its value, unless very
deeply prejudiced. It is idle to reject it because the Peruvian
Government wont let us have it at our own price, because we can profit
by it at theirs. It is nonsense to say, it will answer in the moist
climate of England, but not in our dry one. Truth deduced from
experience, in several States, in various climates and soils, refutes
all such sayings. Besides, it has been used with continued success in
the burning sun and soils of Peru, ever since the conquest by the
Spaniards, and, according to tradition for ages untold previous to that
time.

_Guano on Wheat._--We repeat, sow broadcast and plow in upon all light
lands, _deep_; at the rate of 200 to 600 lbs. to the acre, as you can
afford, or as the land requires--we believe in the small quantity and
repeat the next sowing, to be by far the most judicious. On heavy lands
you may harrow or cultivate it in, but the plow is better. It w
