The prcpelers the lakes have very large exhaurt-
pipes, contracted very sliehtyif at all at their eK
nomtes in the ohimneys, while the high pressure
steamers on cur western rivers ignore altogether the
promoting CT draft by this measure, considering
that the steam rusts ard destroys the cdimneys moe
than it helps the FIRE. 10 locomotives, however, the
blast nozzle ger orally contracted to oice Of b.
tween two and three inches .meter and the vigorous
coughs Of the smoking monsters in starting with q
heavy train, when the steam s allowed to follow at
full pressure attest spunk with which the impris-
oned vapor escspes through its narrow gateway.
NOS, complete device for increasing the efficiency
Of he blast without materially contracting the Of
its escape has been invented By Mr.. VIM. f. Cooper
at The Durkirk terminus Of the Erie railroad. Mr.. G.
leads the eIhsustpires from both engines between
two concen,rc rirgs Of sheet metal placed in the
smoke box and By their ad spreads out the current Of
steam into tube like FORM which acts by the friction
Of both its Internal and external surface BY this
means sufficient draft may possibly be obtained
without contractiLg the area by contracting it TO
the usual amount much increased draft may he OBJ

the petticoat pipes or any Of tie devices for variable
exhaust
BONE LAScTs PoR WHALING BUsIsESs.-The extent
TO which gunpoTder is now being employed in the
manufacture or rather 10 the capture Of OIL perhaps
little suspected by the Of our readers. Guns for
driving the harpoon have, we believe been pretty
tersra ~ abant oned but we are assured by manu-
iac'ureI Of fuse who has lately contracted for making
q usity especially adapted to this submarine and
blubbe,y location, that the bomblance is now beiog
quite extensively employed by many vsHeIs, and that
some have sent home from the Sandwich islands for
furil on supplies. The bomb lance is discharged from
. very heavy mu.ket and is driven point foremost
ipto the vals Of the animal where it e1plodes after
The lapse Of few seconds. the quantity OF powder
usually contained s about four ounces and the fuse is
se Oh fire by the explosion Of the powder 10 the gun.
Brsde's patent bomb-isnce is the one under notice
and consists of thin cy lindcal .tel Of iron armed
with a sharp ard heavy poist Of triangular section
The iron shell is originally open at it's rear end bat
after receiving the powder and inserting suitable
piece Of fuse the whole is stopped wateright by a
layer Of melted lead. The main difficulty appears to
be to find place for sufficient length Of fuse. II
allowed TO project loosely Outsije, the water or the
animal fluids in the wound would be likely to
extiI guish II, and it is a singular fact that all
that portion tightly incIssed within the lead barns
instantly and is therefore of service in post
pOnrs the period of explosion. The method
adopted is to insert two of these eaden partitions be-
tween which, a considerable length of fuse may be
stored Thus arranged, and provided with wsddiBg
which expands into wings to steady and direct toe
msile while hy ing through either air, water. or fish,
the liehIess is sufficient to allow ii. discharge from
piece which may be handled by any strong mau.

SETTING TYPE BY sTTAM.-It may not be known be
you'd a very Dauow circle tia five fu-sized and ex-
per ve machines are in full tide Of operation in setting
type in the establishment of Mr.. Trow in this city.
There is believed TO be in use TO some exten. ia
Paris; but " It'll this exception these the only
chiLes actually working for this purpose within
knowledge. These five give employment, TO ten large,
ard m equal lumber Of small girls, with foreman
to oversee ard ole additional female to supply the
machines with type. Two conposors alternately re-
lleve each o'ber, first stttiig and next jusfsiuy a
qubnty Of matter while the smaller attendants busy
themselves in distributing ana arranging the type for
tie machines. Three thousand ems Of long primer
have be II set per hour or tsenty.sx thousand in
day of ten lous by one girl; but much depends, of
course, o. the skill of tie operator. The extreme c.
pacty of the macf inc is ten thousand per hour equal
to about column and half Of tbs tJpe in The TRB
UNE; but this limit viii probably be never reached.
The machine is driven by band pulley, and the
labor Of setting consists il lingering set Of keys ike
q piano. Each kind is carried forward a separate
band, and deposited ninuousy on single tape run
ring d'sgonsly across the lire of the first From
this second tspe they are dropped into VIII ell which,
in turn leaves them stsn6Dg single file on long ga
lev from which they taken and made up into lines
Of proper length. The enterprise has not until quite
la ly been made to assume form in which appears
pecuri siily Profitable, and even yet mus be eckoned
as hopeful experiment rather than Triumphant
success.
CLEANING AND RENOyATING COTTON wAsTR.-Cott0n
waste, OF the tangled and spoiled products of the cot
ton msI uscture, is extensively used in wiping all
Ii Is Of machinery end is also deposited in consider
able quantities in the boxes OF cars and locomo
ti,6s in which situation it serves asponge for keep
u the sIe always sufficiently fabricated. No other
substar ce has been found so desirable as cotton waste
for iris purpose arc the price of the article uctuaes
slightly with the increasing demand and variable sup
ply bat for the last few years hes been about nine to
IiIS-and shalf cents per pound by the tun.
Several efforts have been made to renovate snd
c'esnss the cd and saturated waste but until lat ly
without success The ar cle has refused TO assume
tate 81 for further service machinery and the Il
rcnse Of preparing it for the paper manufacture has
cxcCedtd its final value The Erie railroad consumes
in this manner ninety tuns per annum, but methoi
as lately been invented by Mr. Charles d. Cooper,
ear inst ec,t in the employ of that company which
