The critical study Of the above data will show
mat 100 lbs Of hay and oats yield about 40 lbs. Of
Dry manure. Ii is known that manure heats, fer
ments, ro,s, and loses weight This chemical
operation can be so conducted as to reduce the
weight one half without essentially or equally
reducing the fertizing power.

need whatever in importing manure from Peru and
Africa. We learn from dealers in the article that

the District Of Columbia alone. Not only can this

will give the Agricultural department of the Patent
Office $500 TO test this matter in a practical way,

aud " i'll be received with great satisfaction by the
farmers Of every State in the Union. It's noretiec-
ton on American agriculturists to say that the
science OF preparing manures is little understood
for we have no agricultural schools in the country,
and neither Congress nor any State Legislature
has given dollar TO foster the scientific inyes!ga-
ton Of fertilizers.
Some may say that this subject has nothing to
DO with agricultural statistics, and that no facts
but such IS relate TO the quantity aud value OF
crops and other products OF rural Industry should

Years" sets down all the hay grown in the great
States Of New York and Pennsy lvana as worth
nine dollars a tun. Nearly all of this hay was
consumed on the farms where il was cut By cattle,
sheep and horses. Now, instead OF being worth
nine dollars tun to rear young stock or feed
sheep four and half dollars is nearer the true
estimate But, while the farmers Of New York
were credited some thirty millions OF dollars for
Their hay crop two prices, they were also cred

In making an agricultural tour through the state
Of Ohio in October lsl9, the writer met with a
gentleman in Springfield who had three nay
presses at work north ot that city on the raitroat
ard bought large quantities OF good timothy hay
delivered, at 50 tun. This hay was sent 10 Ga
cinnati, and shipped to New Orleans and other
southern markets.
In the last Patent Office Report all the corn
grown at the West as well In the Atlantic States
10 estimated at ff,y.HiHe cents bushel; and all the
meat made from this grain is set down at pro-
portionete price. Thus, a Tennessee corngrower
who raises a crop Of 1000 bushels, worth 20 cents
bu,hel, which he converts into tat hogs aud sells
for So 600, is credited frat with $4,000 for his crop
Of corn, ard then like sum for his crop OF hogs
This system is strictly adhered 70 throughout the
whole calculation and with other errors results IN
an over estimate Of some one thousand million oil
dollars. The late Secretary Of the Treasury es.i
