piled anew plan for ventlstipg rooms warmed by
stoves which Is ss foll5ws: Apply vertical pipe TO
the frort Of the chimney, into which the lower end
should enter below the stove pipe sni the upper end
approach within few inches Of the ceiling. 10 it,
operation, The foul cir from the top Of the PUSHES
down and into the chimney, to I'll partial vacuum
occasioDed by the draft from the stove pipe above.
BY applying dsuper to the pipe, its capacity may
be adjusted as desired. This makes cheap, trust
worthy ventilator End is easily applied.
NOVELTY MIR. John w. Kogman Of n. II. and
Mr.. Samuel w. Lowe Of Pennsylvania have each
patented Machines for Milking Cows" As they
both work the same principle description will
give general idea Of their construction and operation.
Flexible tubes slipped over the teats of each
COW, and terminate in a main pipe, to which is AZ
tacbed pump.
In their operation the air is exhausted, when il 10
.leged that the milk will flow from all the udders,
through the main pipe TO suitable receptacle; thus
milking fifty or hundred cows in less time than one
by the hand process.
RAILROAD CAR SPRISGs-A mode Of arranging
cylindrical conical or spiral railroad springs, in
groups placed in double lines vertically, so a. 10 pos
sess the length of scon which two series OF the
springs would have if placed one above the other,
while the space they occupy much less has recent
ly been patented in England. The springs are ar
ranged in Gets Of four more, which are suspended
in brackets strrups and secured at their ends in
slots made in the horns that receive the journals Of
the running wheels.
FAMILY KNITTING MAcHIsE.-J. b. Akin of New
Hampshire has recently patented. and is now manu-
featuring hand machine for knitting hosiery. is
a simple, compact machine; occupies the same space
and requires about the same power az sewing ma
cbine costs geo, and is intended for general family
use.
A NEW REyoLvER.-A novel six barrel pistol, In
vented ard patented by John Wslch, fires twelve
shots without reloading, two charges being placed,
one above the other, in each barrel and nipple and
cap connecting with each charge. This Of course
economies weight and space in the breech, which is
very desirable in pocket pistol, and should it prove
as accurate and in its operation as the single
charge barrels, will be valuable improvement.
A HIGH BRIDGE FROM EsGLAsD TO FRAsCG.-
This magnificent project is being seriously entertained
among engineers and men of science. There have
been equally as wonderful things effected in day.
The English papers have published come Of the de-
tails Of the plans for uniting England and France by
gigantic tubular bridge across the channel between
Dover ard Cape Grinez. In order to afford passage
to vessels of the largest sze the bridge would rest
on the side the cliffs of Dover, and on the other
ride On the CLIFF Of Cape GIinez, the French abut
mens being raised lj3 feet higher than the English 70
compensate for the difference Of elevation Of the cliffs.
The bridge would have been supported by 100 towers,
at distance of 500 feet apart each having light TO
guide vessels at night and alarm bell for warning
in fogs. The greatest depth Of the channel on the
line proposed is 1876 feet. The bridge would have two
more railways, which, ID is estimated, could be
Travelled in twenty minutes and it would be 30 built as
70 admit the light Of day-being lighted at night by
gas In order TO prevent all fear of INVASION the pro-
ector proposes that each end of the bridge shall be
commanded by a strong battery. The towers, which
would be 100 feet 10 diameter, and 200 feet high would
rest ON colossal bases 800 feet square at the bottom,
$50 feet square at the top rising to hight OF 4O feet
above the water formed OF blocks OF granite united by
iron bars. The elevation of the tops OF the towers
would thus be 300 feet above the surface OF the water
Mr. BOYD estimates the utmost possible cost of the
bridge at $50 100000 but thinks that It could be but
for half that sum, and that the whole cost would be
reimbursed to the company in eight years.
IMPROVEMENT IN PHOTOGRAPH PRINTING. - An
achievement has been accomplished in the science OF
Photography by of cur citizens, which will work
complete revolution in the art OF picture taking
either from nature by copy. Its success Is tn
umph Of patient investigation and labor under the in
husnce Of impelling genius which Is rarely met WITH
and which deserves prominent notice as an application
Of elementary principles to object calculated to be OF
great practical use The inventor Mr. Chas Fontayne
an experienced Photographic, to whom his profession
was mainly Of interest because Of Its pleasant field for
experiment and development, during long penod OF
illness matured III his mind plan long considered, OF
multiplying exact copies of picture OF any kind with
great rapidly that for the Infinite variety OF uses TO
which eDgTsvpgs of any kind may be put, this system
Of copying must supereede all Others. Inc copy WI
be exact, DO matter what the original either Of the
most delicate engraving, or the largest physical objects
which may be encompassed in the lense of ,amera.
The process is surprisingly simple IN view OF the re-
suits accomplished and in this is its greatest wonder
chemically prepared sheet Of paper, on which II 10
designed to print picture placed on cylinder, made
to revolve regularly in a box, receives, through an
aperture in the side OF the box the eIsct reflections OF
negative of the picture TO be taken. The refrachons
Of light admitted by instantaneous flashes only be-
ing cut of fast the cylinder moves on its AXIS TO
bring up the surface Of the paper for new mpression
and this motion may be a. quick as mechanism can
make it, for the print is made apparently as fast a.
light travels An application Of chemicals after this,
develops the picture as perfect tone and appearance
as any prepared after the old method and calculated
to be entirely durable. The system is called Tales

The Artisan
ParISrs AND CoPYRIGHIs.-The Commissioner Of
Patents has issued circular defining the difference be
tween an engraving which is subject Of copyright and
label which is subject of patent only. copyright
costs 80 cent? and gives monopoly for twenty years,
while patent costs SIS, and gives monopoly but
seven years. The Goa missioner decides that when
production is issued work Of art and is intended
for sae such, ii may be copyrighted but that when
