nch or two deep six inches from each stalk. A table
spoonful to the hill will take 250 to 350 lbs., per acre, according to
the distance the hills are apart. If the soil be rather poor, a second
dose at the time the corn first shows its silk, will add considerably to
the yield in grain, if followed by rains, but little or nothing to the
growth of stalk. Guano increases the size of grain more than stalks;
hence one must be content to wait till the grain is fully matured before
giving an opinion of the virtues of guano.

"Before applying the guano, it is better to mix it well with an equal
quantity of plaster of Paris or charcoal dust. Either of these
substances help to retain the ammonia and prevent its evaporation.

"The genuine unadulterated Peruvian guano, is so much superior to any
other kind, it is in reality the _cheapest_, though the price is
considerable higher than that of the other qualities."

_Guano on Oats._--Mr. Allen says, "I am satisfied from experience and
observation in the use of guano, for the past twelve years, that the
best method, decidedly, of applying it to crops in our dry climate, is
to plow or spade it into the ground; and autumn is the best time for
doing this, as it gives time for the pungent salts contained in the
guano, to get thoroughly mixed with the soil before spring planting. Do
not fear to loose the guano by plowing it in as deep as you please--it
will not run away, depend upon it. At the south, it loses half its
virtue if not plowed in at least three inches deep; six or twelve inches
would be still better."

Because "autumn is, for many reasons, the best season" for applying
guano, as a general thing, we do not recommend an application to this
crop, notwithstanding our full conviction it will increase the product
upon any light, poor soil, from ten to twenty bushels to the acre, for
each cwt. applied. As some however, will find it more convenient and
profitable to manure the oat than wheat crop, we recommend them to plow
in from 200 to 300 lbs. to the acre, on ground that was clean tilled the
previous year, and sow the oats in drills, three or four bushels to the
acre and seed with clover, herds, or ray grass. If not to be followed
with grass, we would use a much less quantity; say 125 or 150 lbs. to
the acre. As may be seen in the account of Mr. Harris' crop, not one
half of the 400 lbs. was taken up by the oats. With wheat, on the
contrary, the guano is dissolved more slowly by
