= New Mechanical Principle.

.On Monday week, a public trial of the Satellite,
or Iron Slave, invented by j. y. Etzler, Esq, and
constructed by Mr.. +. Atkins, OF Blcester, Tor the
Tropical Emigration Society, was made in the
neghborhood of Biceser, OXiordshire. The hrst
public display of this invention, which, al distant
period will change the system OF agricultural labor,
especially in warm climates, and substitute iron
slaves for human slaves excited good deal OF inter
est. The machine is intended for agricultural pur-
poses. such as blowing. sowing, reaping; also Tor
making canals roads and tunnels. Ii Is frame OF
iron OF four feet wide and twenty feet long, with
shaft Of seven feet long in front, and shaft OF SIX
feet six inches long behind with two broad wheels,
and steering wheel on the extreme end. On the
front shaft are feet similar 20 spokes OF wheels with
buffers on their eXremliies these enter the ground
bv the revolving of the shaft. This is caused by
long lever of twenty feet swinging backwards and
forwards on spindle, and pulling aternallvely two
levers of three feet in box on two wheels, iXed 10
the shaft similar to the capstan on the Great britain
s,eamshiI-with the difference, that the motion can
be reversed, the levers 50 placed, that they VII
bea,e, without touching the driving wheel The
power to work this machine IS communicated by
ropes, pung alternately on the lever these ropes,
al 4 distance of 4 hundred yards, were wound
around double drum, and corresponding ropes ran
from the drum 10 distance OF farther 100 yards,

or shortening the communicating ropes the distance
from the prime mover 10 the machine travelling
around It's satellite, be from twenty yards
to 600 yards in diameter. The ropes from
the prime mover to the central travel upon
pullies and rollers TO diminish friction and from
the drum 10 the satellite, they are held up
by cars with poles if they extend TO great dis,
lance to keep them from the ground. The trial
itself proved fully the practicabity OF the machine
and The applicability OF the mode of transmitting
power by levers and ropes from fixed point to
moving point; although, owing TO some minor
causes such rs smaness of some pullies, and an
oversight in the steering OF the machine, ii was
not quite satisfactory to the general pubic VINO
