This opinion, so different from that en-
,ertained by some o,hers.is no, lightly form
ed, nor without several years careful OBJ
servalion; and also testing The matter by
numerous experiments, and on scale suffi
cienlly extended, to prove the truth, or fal
lacy. Of the doctrine held BY some, ha. j
is only s,imuant Reference To one ex
pertinent may suffice, as they all tend to The
same result, and nearly to The same degree
In field of some 10 acres, one acre was
selected near the middle, and extending
through the field, so as to embrace any dif'
ference of soil, should there be any. On
this acre 200 pounds of Peruvian Guano, al
a cost Of about $500, we're sown with the
wheat. Adjoining the Guano on one side
was manure from the barn yard, Al the rate
Of Is cart loads to the acre and on the op-
posi,e side (separaled by an open drain The
whole distance ground bones were applied
on The balance of the field, at a cost of So. 90
to the acre: the field equally lined two
years preceding. There was no material
difference in the time, or manner of seeding;
except that the manure was lightly cross
ploughed in, and Gnano and Bones harrow
ed in with the wheat.
The yield on the gnanoed acre was thir-
ly-hve bushels The adjoining acre with
bone, as near as could be estimated by do
zens, and compared with the Guano, was
about 81 bushels and the MANFRED, about
"a bushels. The season was unusually dry;
and the MANFRED portions suffered more from
this cause than either Of the others the
land being considerably more elevated, and
a south exposure.
The field has since been moved three
times; the first par, Of grass was evidently
in favor Of The boned part the second, and
third, were fully two TO one over the Guano,
and also yielding much heavier crops of
clover seed. On a part of one land, Is
bushels 10 the acre of the finest Of the bone
were used; on this, the whea, was as heavy
as on the ghanoned, and the grass general,
lodges before harvest as it also does on
much Of The adjoining land with IL bush
els of bone.
The action and durability Of Guano, pro-
badly vary on different, soils and although
i, may generally be used to advantage in aid
of single crop, have as YET, no salsfac-
tory evidence, that its fer,ilizing properties
are very durable: unless applied in such
quantities, as may in the end, 'cost more
than it comes to-"
Guano should not be used with caus,ic
lime, or ashes nor very soon succeeding
their application. II may with decided ad-
vantage be mixed with plaster, to fix and
retain the ammonia; and for nearly, if not
all crops. i, is best TO SOW it broadcast, and
plough in Immediately.
Leached .Ashes.-There are few, or none,
who are ignorant of the value Of this article
as manure. But as the supply is rarely, if
ever equal to the demand, much need no,
be said ON the subject. At 8 to 10 cents
per bushel, if the cost of transportation is
not too heavy, they may always be pro6,a-
bly, used in durability they are next to
lime. and the ac,lon immediate. Few COM
para'ively, except within the vicinity of ci-
ties or villages, or those with water or rail
r"ad facilities, can procure, or afford 10 use
them.
Poudreth.-Much profit has not result
ed in the use of this (the merchsnlabe)
article, so far as have observed its efferIs
on my own, or the crops Of others. Such
as have purchased, has as yet produced
but slightly beneficial results on the crops
to which it was applied. lis ferIilizing
property was dffused through such mass
of inert matter. tina, concluded with half
if no, one-,hird of The expense, more bene-
fit might be derived from the purchase OF
some other kind of manure.
In the neighborhood Of cities, where a
supply can be obtained without so much
adul,era,on, its use may be made very pro-
filable.
Turning in Green Crops.-This plan OF
"renovaling worn-ou, lands,' has long been
advocated by many. have also given j, a
fair trial and with The exception Of CLOVER
