The analysis Of the fluid aud solid excrements

gradients of the soil which do not remain in the
body Of the animal contained in its excrements;
il shows that in an adult animal which from day 10

amount Of the mineral ingredients OF the excre.

The excrements Of man contain the elements Of

meat.
These discoveries explain. in most simple and
satisfactory manner, the fertilizlng effect which ma
nure produces our fields.
Il is now obvious why manure renders again fer
tile the exhausted fields why, by its means, their
productiveness can be augmented; why the latter
is in direct ratio TO the quantity OF manure adj
mnstered.
The exhaustion of the soil by subsequent crops,
its decrease in fertility is produced by the gradual
removal Of the mineral elements in soluble state,
which are necessary for The development Of cul-
tivaled plants By supply Of manure they are
again restored TO the state suited to as nour'
ishment to a vegetation.
IL the supply Of the removed elements Of the
SOIL by means OF manure, be sufficient f the guam
tity taken away be restored The original fertility re-
appears il the supply be greater the produce in
creases a defective supply gives a smaller produce.
II is now explained why the different kinds oil
manure exercise an unequal effect upon the fields.
We should like to publish the whole Of this article
and may in another number, il we find our reading
farmers are interested in il.
Professor Liebeg has made practical use of hi
discoveries. Having found by the science Of chemis
try, Of what properties the different grains extract The
SOIL and in what combination Of manures these prop
critics found, he has prepared mauures FOE the sew
eaI kinds oil grain for which he has obtained patent
These manures are classed, and numbered Tor lh'
different grains, and SOLD at ten pounds per ton. HI
says Of them:
As regards the cost attending the use Of thes
manures, slight consideration Of the subject viii
show that mannrng with them will be cheaper thar
manuring in the ordinary way. For instance, TAX
the wheat manure; the price is ten pounds ton
but cwi only are required for an acre, and as ey
cry particle is adapted to and acts favofaby on tn
crops, the farmer pays only for what is useful
) him, whereas hitherto he has furnished his land
: with the unnecessary aud useless along with III
E necessary and useful, paying for both at the sam
rate Farther, it is the object Of these manures L
render the change Of crops and following unnece'
a sary and superhuous wIrn THEIR USE ONE AN
THE SAME KIND OF CROP MAY BE GROWN YEAR Al
: TER YEAR UPON THE SAME FIELD.
