performed just before or during
rain, the action will be quicker and more effectual."

Four or five teaspoonfuls of dry powder producing such an effect, is
what staggers the belief of those who see with their own eyes.

So great is the luxuriance of growth from such an insignificant
application, it is necessary to increase the space nearly double between
the hills. In a country where fodder is so valuable as it is in
Massachusetts, the great increase of stalks is of equal importance with
the increase of grain. Indian corn requires both phosphate of lime and
magnesia which it finds in guano, in combination with ammonia, in a
state just ready to be absorbed by the growing plant, wherever brought
in contact, with its roots.

Mr. T. found the guanoed corn planted May 22d, ripened sooner than that
planted May 1st. with manure. This alone on account of the difficulty
from frost, is sufficient to give it great claim upon northern farmers.

_Effect on Grass._--"The application of this manure to grass land
already laid down is for many reasons often attended with uncertain
results. The best mode is, to spread broadcast about 250 lbs. per acre
of the Peruvian guano as soon as the snow is off the ground. It would be
very advantageous if, after it was spread on, some light loam could be
put over it, in the manner of a top dressing. I state the Peruvian guano
is the best for this operation, as it contains what Dr. Ure calls
_potential ammonia_, or ammonia in a more permanent form; whereas the
ammonia from the Ichaboe guano evaporates more easily, and this valuable
ingredient is therefore lost in the atmosphere when it is spread on the
surface.

"Most excellent crops have been obtained, where the grass is sown and
laid down in the autumn, on light, sandy soils, by sowing the guano
evenly broadcast, then harrowing twice, sowing the grass seed, and
rolling."

The best mode of applying it, however, is to sow broadcast and plow it
in--at the south, on sandy soils, no matter how deep--at the north on
soils more clayey, plow it in about four inches deep--the real object
being to so mix it with the soil as to prevent the escape of ammonia,
which is exceedingly volatile. Remember, _Guano_ should never be used as
a top dressing, except in combination with plaster, or some other
substance which will prevent the escape of the most valuable portion of
its composition.

In several case, where sods have been laid down for lawns or
