The Po,rer Of Steam 4 pint of water evap-
GRATED b. two ounces Of coal, swelis into two
hundred and sixteen gallons of steam, with a
mechanical force sufficient to raise a weight of
thirty seven tons fo,t high BY allowing it to
eXpant. by virtue Of Its elasticity, further me-
chanical force may be attained, at least equal in
amount to the former
Five pnts Of water. evaporated by pound of
coke IN u locomotive engine, viii exert me-
chanlcal power sufficient to draw two tons
weight on railroad distance of one mile in
two minutes. Four horses in stage COACH on
common road, wili draw The same weight the
same distance IN eight minutes.
-Four tons OF coke, worth twenty-five dollars
will evaporate water enough TO carry on rail
way train Of coaches weighing about eighty
tons, and transport two hundred and forty pas
sengers, with their baggage, from Liverpool to
Birmingham and back again, total distance 100
miles, IN four hours aud quarter each way. To
transport the same number of passengers daily
by stage coaches, on n common road between
the same places, would require t. envy coaches,
and an establishment Of three thousand eight
hundred horses. with which the journey in each
direction would be performed IN about twelve
hours.-Dr Lardnsr's Lectures.
Grain Fields of The Uest.-The Cincinnati
Gazette furnishes the following paragraphs, which
give some idea of the grain producing ability OF
the great West, and of the extent to which that
ability is garfield
james Davis, of Waverly, Ross county. o,
cultivates 1850 acres exclusively IN Indian Corn,
aud has th.s winter corn crib filled, phich Is
three mules long, ten feet high, anu six feet wide.
We presume this is one of the largest corn fields
in the world, wued by single individual.
On the Great Miami Bottom, adjoining Law
rcnceburgh Ia, about % miles below Clncn-
natti, there Is one field seven miles long by three
miles broad, extending in fact to Aurora, which
has been regularly planted down 10 corn for near
iy halfa century. 1t is not cut up by fences, al
though belonging TO about dozen owners, all
of the families OF the Hayes, Guards, aud Nil.
lers. Although corn is one of the most exhaust
ing crops, no manure is ever used, and the soil
is deep, strong and fertile ever.
The Wabash Valley Is also remarkable for
the extent of It's corn fields. Between Terre
Haute aud Lafayette the road may be SAID TO
wind through n continuous corn field one field
being certainly ten miles long.
In the northern part of Indiana, wheat is more
generally cultivated, and between Lsporte and
Michigan City, the road runs for ten miles through
a magnificent wheat field, without a single dIy-
sion fence, though owned by several individuals.
Perpetual .Hoiion.-A writer in the Chayles-
ton Mercury asserts with considerable positive
ness that the dream of inventors has at last been
realized, and that perpetual motion is finally
discovered He saws:
ave sometime since notice of the dis
covery of this principle in the construction of
self-moviug wheel, by Mr.. Rochester. of Madi-
Son, Georgia; and, as in former ola SINH
laI kind, set II down as one of the latest abor-
tons Of some eccentric and dreamy mechanic
On yesterday, however, we had the satisfaction
OF seeing the veriiable wheel itself and from a
careful examination OF It's parts, which we're Ia
ken in pieces and re-arranged in our presence,
we do not hesitate TO pronounce it seIi-moving
wheel, which, If let alone, would without ces-
SALON, and untouched by any one, move until the
materials OF which 1t Is composed decayed from
the influence Of time, and such causes as act up
on all perIshable objects. The power is SO great
when once in motion, that unchecked by proper
means, 1t would Cause It's own destruction"
