OF We call attention to the article from the Phil
adelphia Saturday Courier, containing we'll deserved
encomumS the Directors of Railroad for their
beraty in sustaining Mr. Cathcart in the prosecu-
ton of enterprise which, although it will be to their
benefit, was as yet untred We hope sincerely that
the experiment will succeed-and we have every rea-
TO think it WILL both from the character of the
inventor, who has not his superior in the West as
thorough mechanlcian versed IN branch relating
to mechanical forces, and the opinions of well quail
fed pro eSsonal men. Mr.. Cathcart is claimed by
the Courier if he were Philadelphia mechanic;
but he merely exercised his calling there for few
years, and is now essentially Western man.
BY the simple improvement on breaks, he saved the
company, in the of three four years. between

NEW LocoMoTIvE.-A new and splendid locomo-
tive with quite feature in construction from
the well known shop of Mr.. M. w. Baldwin, left this
city Friday last destined for the Madison and In
dianapolis Railroad. And as it is the intention of
that enterprlsing company by means of this engine,
to supply the place of stationary engines and horse
power, inclined planes, think it proper give
description of its construction, as it may be inter-
esting TO many of our readers II is large and pow
erful locomotive placed upon eight driving wheels,
which are connected to pair of inclined cylinders,
fifteen and half inches in diameter, and twenty in
ches stroke. There is also a driving Cog~wheel,
twelve and a half inches in diameter, for propeng
by rack laid In the middle of the track the whole
length of the plane This cog-whee is on the middle
of shaft lying parallel to the axes of the driving
wheels, and midway between the back and front ends
of the engine, aud, by crank on each end of the
shaft, is connected to pair of vertical cylinders, four
teen and half inches In diameter, and fourteen in
ches stroke This shaft is placed in pair of strong
bearings attached 10 the boiler and framework of the
engine, and is raised sufficiently from the rails, and
connects to the rack by intermediate wheel, twen
ty-eght inches in diameter and which is capable Of
ha1rar ofa1a II
from the rack, at the pleasure of the engineer, by
means of fifth cylinder placed horizontally top Of
the boiler and ny crank and two rods 1t is connect
ed the ends of the intermediate shaft. By admitting
steam into either end of this cylinder, the ntermed
ate shaft and wheel raised lowered, at the will
of the engineer, and will accommodate themselves to
the unduations of the track. The drvngShaft OF the
twelve and hall inch cog-wheel is furnished with two
friction brake-whees, twenty inches in diameter,
by which the progress Of the engine in ascending or
descending the plane be nstantaneously stopped
graduated TO any degree of velocity, at The pleasure
of the engineer.
The machine was tried in the yard of the work.
shop in the presence of number of practical engi
neers (prevcus TO being shipped 10 its destinaton)
upon temporary track for that purpose, and its per-
Torrance gave the highest satisfaction, being entirely
under the control Of the engineer 1t may be started

the rack al pleasure, without Jar and almost insan-
taneOusly IL was also SHOWN t1at oy putting tne IN
cined cylinders in backward motion, aud the verti-
cal cylinders in forward motion, the gearing would
cause the engine slide forward the track while
the eight driving wheels were revolving without eff
feet in a downward and backward motion, clearly
showing that by the above improvements the engine
will have more than double the tractive power Of any
engine of the same weight. The improvement is by
Mr.. Andrew Cathcart. Of Madison, Ind. formerly Of
this city, and under whose superintendent she
