EXHAUSTION OF THE SOIL.

Prof. h. IL harrington OF Wisconsin
Agricultural College. in speaking of
Soil Exhaustion, made very interest
ing statement regarding the selling Of
GARY products from the farm as COM
cared with selling the grain produc-
lions directly off the farm. Here 10
what he says:
"TherS is d great difference in the
amount OF soil fertility removed from
tne farm by selling crops as compared
with the selling OF cream and butter.
The constituents of the soil that be-
come most easily exhausted by farm
Ing operations are the nitrogen. the
phosphoric acid and the potash. These
each have market value per pound
and can be bought in commercial fer
tilizers. They are also contained in
farm manure.
IAN analysis OF different crops and
Of milk, butter and cheese will show
how much of these various constitu-
ents are removed from the farm when
= certain quantity Of these products
are sold. For instance, by using the
came prices per pound for the follow
ing crops, etc, we find that the fer
tilizing constituents taken from the
soil when one ton Of hay is sold from
the farm have value of $4.34, one ton
Of corn 1886, one ton Of wheat $3.50,
one ton of milk $2.17, one ton Of skim
milk $2.31, one ton OF butter 40 cents,
one ton OF whey 81 cents, and one ton

ton OF these different products Is well
known. For instance, the ton OF hay
may be sold for $4,000, while the ton
of butter is worth 100000 and ton
OF cheese $4,000. These figures show
however, that il the crops raised on
er cream or butter only Is sold then
for every 100000 worth of butter only
so cents worth or fertility is drawn
from the farm"
In encouraging the farmers to en-
gage in dairying, Prof. Harrington
says:
"Dairying keeps up the fertility OF
the soil as already explained
"Skimmilk is very valuable to the
farmer not only for the reasons given,
but because it IS profitable for far.
mer to become a stock raiser--that is
raise calves, pigs. poultry, etc, rather
than crop producer and seller OF
grain.
Dairy products, butter and cheese
are not bulky to market, being much
more concentrated and the cost OF
transportation less than 1t is for hay,
grain. etc.
"Dairying Utilities waste land, such
as stony pastures, timber and swamp
land, which may be used for pasturing
the COWS if these are kept, but which
otherwise would give no returns.
"Dairying gives profitable employ
ment during the entire year and idle
ness is not good for either man or
beast"
A visit to the National Dairy Show
at Chicago, October oath to November
End next, will give every one a short
course In dairying that cannot be
equalled anywhere In the world, and
all such matters as here discussed by
Prof. harrington will be illustrated by
