produced 6y tllsi most iili Is
and Ingenious piece OF mechanism IN thezI Ihols
Exhibition.
By the side of this Rake stands an odd
looking machine, unlike anything else IN the
Palace and perhaps unlike any thing else on
earth. This is gibbs RoTARY SpADE The
description we have seen does not convey
very clear idea Of the thing, but we under
stand it to consist OF series Of narrow spades,
something like tho teeth OF the old fashioned
cultivator, which arc set in a wheel and made
to reyolve and dig up the earth one after an
other, the whole being drawn by two oxen
Two of these wheels are worked at once, and
contain eight spades each, which shovel up a
space about two feet wide to the depth of nine
inches. The width, or depth, or both can
readily beincreased by enlarging the machine
The inventor comes from Washington city.
Pratt's DtTcH DIGGER operates upon simi4
lar principle. 1t has twelve blades arranged
round an iron circle. They enter the ground
as the circle rcyolves, each takes up load of
earth and carries it to the top of the machine,
where it is discharged upon conductors which
carry it off upon each side. 1t requires one
pair of horses and one man to work it, and
where the ground Is favorable it will cut $50
rods day, no less than two feet. In bard
and stony ground it will cut from so to 100
rods, by using an extra hand in ditch, with a
pick Such at least is tho statement of the
inventor, who halls from Canandaigua, N. Y.
A PATENT PTa-PEN is one of the curiosities
of the Exhibition. 1t is a model of an improv-
ed plan for feeding swine. Instead of feeding
trough, there arc series of cast iron basins
set in a bench about foot high, over each of
which is IN iron frame to keep every pig to
his own dish. Over these basins there is a
roof, and the side of the pen in front of them
is hung upon piyots, so that.it can be pushed
back at the bottom, shutting the pigs in and
the trough out. When it is filed the bolt is
withdrawn, and the force of hunger pushes it
back into its original position. 1t is very
ingenious affair.
A PATENT BRooM is represented as worthy
of notice. ltis the first corn broom ever pat
ented, and, as we understand it is rather a ma
chine for making broOms than a mere broom
itself. Any one WHO has broom corn can
make his or her own brooms, and be inde-
pendent Of the store-keeper. There is no
twinc, no wire and no stitching about the thing.
There is fat steel spring, six inches long
with Thread inserted in the handle; and
over that is hinged socket, which being
opened, the broom corn is laid upon the SPRING
with the butts in the sockets, which as well as
the cross head of the spring is covered with
teeth, which hold the corn To keep it in It's
place, now shut down the hinge of tho socket,
and slip a ring down over tho corn about the
point where the twine is generally stitched
through-and your broom is complete One
of these handles, which does not cost a great
dcal-will last for years, and the broom thus
made has a decided advantage over the COM
mon one in this, that the handle does not pro-
ject down into it, but the steel spring gives it
a pleasant elasticity until it is completely worn
