VALUE OF MANUFACTURES IN HAssAcHusErrs-
According to the statistics recently published the an
pual manufactures of Boston and its vicinity and the
other principal towns of Massachusetts, reaches the
enormous amount Of three hgsdred Millions OF dollars,
or ne million for every working day in the year.
McConB's IRoy CLAsPs.-The editor Of The Vicks-
burg Wke has been shown new invention for last
ening iron bands upon bales Of cotton, 20 as to allow
of their use as substitute for rope. The fastening
can be done much sooner than rope can be tied IL
made by bending over each end Of the strap 30 as to
form two hooks and when is placed in the other,
sliding clap is placed over them, which confines
them inmovs They are sad 10 obviate the objec-
| tions generally made heretofore to iron band'
Coal FOR LOCOMOTIVES An engine with Q
"Boardman" boiler has been running on the Provi-
depce and Worcester Railroad, burning Cumberland
coal with complete In round trip she burns
two and half tuns, costing sl5 while with wood an
| engine of ike power would burn four cords, worth
| from s25 10 S2s -Four more Of the same sort are
being constructed at Msson's shop in Taunton.
WuLIANss TRAcX.JAcK-A leverja designed
partculs,y for railroad use, is being introduced by
Me.sr.. Elliot and Bowlts of this city. They are very
strong and convenient t faster than the screwack,
are much cheaper, ard decided Improvement on the
| cid lever.jsck.
EtIIrpoRP's IRoy PAvENEyrs.-The latest and
we believe Gays The Inrentor, monthly Journa! OF
thus city, the best pavement which has been brought
10 notice il made Of series of groned arches, alter
mating in position in each adjoining row, to make
.urer oothod for horses travelling it, and to pre-
vent the wheel of q vehicle from jsmnng in it. The
blocks are kept place by snged projection catch
ing over OF block and under the next, 80 that when
once properly placed there chance Of their being
disturbed by the travel upon them while they san be
readily taken up ard replaced when required.
CAR BRAKEs.-Several promising plans have been
tried of late for enabling engine to stop trains of
cars without the aid Of brakemen. Lougbridges
American Car brake has been abandoned for the pres
ent on the Hudson River Road Millers Steam-brske
is to be employed still extensively on the New.
York and New-Haven line; and Creamer'S United
States Car.brske is to be publicly tested on a large
scale at SDg-Sng next Tuesday. All these devices
aim to Increase the safety of railroad travelling to
very great degree. The race now lies between hr
Creauer and Mr.. Miller, both of whom have engraAed
very considerable improvements on their inventions
stree their first introduction.
BI-SrLPHURET OF CARBON ENGISE.-Hughess in
venton of using the vapor of this material instead of
pany lately organized in this city.
CANAL BoArs-Sxteen boats have just been built
at Rochester of the largest class which can navigate
the enlarged canal. They are each 90 feet long, II
feet wide and average nearly 200 tuns burden. They
are built for the National Transportation Company
ATMOSPHERIC -Richardsons under
ground tube through which parcels are to be sucked
by pumping out the air at either end is on exhibition
at Washington and there is prospect of an ex-
pertinent a large scale.
HEATING The EXTERIOR OF SrBAM CYLINDERS
The Glasgo~ Practical Mechanics Journal gives
welLaitesed case serving to illustrate the utility OF
the Jacket formerly used to surround the cylinder
with steam. A larOe engine tried alternately with
and without steam IN the jacket required but
twenty pounds pressure to perform in the iest named
case the same labor as required twenty five pounds
in the second.
CosT OF HORSE PowER.-A recent discussion in the
British Society of Arts the practcabil,ty of en-
pyDg steam power for farming purposes brought out
an estimate that ESQ ooo, ,ooo-equal to about e2io,
Ooo-are expended annually the keep Of horses
employed in agriculture.
FLoAIISG STEAM FIRE EScrSE The ferry boat
Nassau, of the Wall street Ferry, has a No. s
worthington steam-pump permanently board to
at serious fires along the docks. Steam being
always up in the boiler aca from the proper author
ties would bring to any part of the city ada
cent to the water very powerful and never-tiring
pump The cylinder of the pump is little larger than
the largest hand fire engines.
STEAM FIRE ESGiyE.-The Boston Transcript
states that the single steam freeDgDe purchased by
that city time since has been laid by IS useless
lumber until quite recently when it brought out
and obtained the highest commendation by its per
formance.
GALvASoGRAPHY-Mr. Paul Pretscb, late manager
of the Imperial Austrian Printing Office at Vienna, has
inverted method Of preparing engravings by the
action OF light in a similar to the Daguerre-
otype, rather the ambroype art. Glass is prepared
as for a photograph, exposed to the light in the
camera and subsequently treated first with solution
of borsx then with alcOho then with copa varnish,
and finally with asrDgent solution, aided by heat.
The result is picture in relievo which being supplied
with ink will tranfftr to lthograph stone picture
which The Giasgop Practic4y Mec1anics Journal |
sffirms possess a fidelity which artistic labor
can rival" An Influential company has been formed
in England to carry out the object on large scale.
PAPER FROM New MAIERIAL-A Mr.. Brown has |
recently developed process in Scotland Of making |
from fern stems stalks paper of excellent quail
ty, which, though unsized, can be written on with
out the ink running. The stalks first beached, |
Il en- reduced to pulp in the manner as rags, and
finally treated with water until the gummy matter is
mostly removed When mixed with rags it is sufh
ceptly glutinous to make sizing unnecessary. Paper
is manufactured with success from bsswood at Little
Falls, Herkmer County, in this S,a.e. The paper is
too strongly yellowi.b, however, to be valuable for
printing.
