GooDMAs's AXLE Box There has been for some
time in successfu operation, uuder freight car, on
the Buffalo and New.York City Railroad, novel
species Of box invented AID patented by Mr.. John
Goo6msn, one Of the mechanics employed by the
Company. This box resembles, in external APPEAR
arce IL at ordinarily employed for this purpose but
the friction Of the journal Is received vegetable,
rather than metallic substances. Mr.. G casts box
Of iron, provided with number OF ribs on its nte-
ror between and up4n which hemp, cotton waste,
leather sbavings or otherfbrous ma'eras previously
well saturated with talow and sulphur, is tightly
driven with calkiDg.iron. In short while the use
Of hemp has been discontinued as packing for p.tons
in stesm-cy finders, and its place supplied by metallic
rings Mr. Goodman has discovered that in other sta
out the exsteIce Of high temperature the reverse
may Obtain and hemp may be substituted to advao

been nov in use between four and five months in the
ersveltrsp and during two months of the tine, wa,
only oiled twics. There ia cavity the top, Of sui
fcitnt size to contain about / pint Of oil or taow
protected from dirt by suitable hinged cover, while

Of the box, pete Is about 60 pounds-that of the

Of fttire-uP being very nearly equal it results that
the henp-psckeo box Is cheaper than the ordinary

The HOWE RIG The msnmoth clipper ship
Great Republic, re6tted since her plr'is destruc
ton by fire. exhibits lev method Of divid NJ aud
arranging her tepssils, invented by Capt Hose, of
Massachusetts, and frs, applied by him on clipper
ship of 900 tuns uIder his command THIS rig,
which has been terhed by some the Climax" Rig,
after tie Of thi. sbp, ard By others the Howe
Rig after the name of the inventor. has, within the
past year, rapidly gained in favor with the nautical
community ard il now borre or is about being fitted
on some scsre Of vessels Of large size. The pecu-
liaity unlike that Of the Forbess, whchit somswh,
resembles, vvpcd ens;soiy tho topeai.s, psa
yards ard braces, and doe not extend a. does the
latter in many cases to the locating of the topnasts
abaft the mast Both patents divide the opsail bod-
zontally into two, upper and lover topsai, for
convenience in handling, &c; but there some
points of importance 10 which The Howe is believed
to be superior to the already quite popular Forbes
Rig. The Forbes has opg mast. head with the lower
topssil.yard running up and down upon it. The
howe Rig has merely extra stou, cap at the top of
the mast head, and trusses the yard thereto In
per very similar to that by which the lower yard is
yard is borne by brace of iron rising from beuesth
The lower topss has neither reef points ncr tackles
ard we believe In many cases both clewllnes and
buDtLss dispensed with Halliards are of ,urse
needess on yard without vertical movement and
the rig is thought by many to be much simpler, aud
in several respects preferable to any other.
MMLERs STEAM BRAKE.-A steam car-brake de-
signed to supersede the one operated by hand on
our railroads, has been invented by Henry Miller,
ESQ., Of Detroit, and it appears to be very decided
improvement. 1t was tried upon the Pontiac Rail-
road last fall and since that time has been put to
come pretty severe teets upon the Michigan Central
Railroad. On the 18th met 1t was applied to q train
five cars viz one baggage, ole second-class aud
three passenger cars drawn by locomotive weig hing
twenty eight uns with inch drivers whole
weight Of train l0i tur sand brakes were applied to
twenty pairs Of wheels, under The cars only. The re-
suit follows: the first trial. with the train
moving a. the velocity Of thirty miles per hour, the
train was brought to perfect stop in seven hundred
feet, taking twenty seconds OF time. On the second
trial. with train moving forty miles per hour it
brought to stand still in nine hundred and forty-fv
feet, and twent yak seconds Of time On the third
trial the train was backed do IN two miles, and com
Dg up run the last ME III one mlnuS ana twenty
five seconds. II was brought to full stop in one
thousand aid six feet taking tseny eight seconds Of
time the train not running three miles per hour
for the last three hundred feet. The invention If
whs. it seems to be, is avery important one a num-
Der Of accounts: l. A train can be stopped in ono
third Of the distance and one third Of the time usually
required at stations. q The ssoppage q control Of
the train is given to the engineer, the only person
who can know the necessity Of stopping and the dan
