Rapid Bridge Building.
Oar readers hare already been informe'd of
the wonderfully short time ocoupled by Thos.
Jl. Scott, president of tbe Pennsylvania rail
Toad, in rebuilding the bridge over the Hohuyl
klll, at Philadelphia, which was recently de
stroyed by fire. The bridge formed a portion
of one of the main thoroughfares leading into
that city, and every day's delay of its comple
tion was a serious loss to its business interests.
The time ordinarily occupied for the construc
tion of such works would have menaced the
success of the work upon the Centennial build,
ing, and even the great exhibition itself. Hence
the urgent necessity for extraordinary celerity
in its reconstruction. In this, both the city and
nation's dilemma, Col, Scott stepped in, and
rendered the city and country a Bervice which
will stand as a monument to his skill and
efficiency, perhaps until another centennial
anniversary shall roll round.
Years bad been required to build the old
"bridge, and now the necessity required, if
"Within the bounds of possibility, that only a few
dayi should be allowed for its reconstruction.
So great was the emergency that tbe contract
was signed befors the embers ot the old struc
ture hid soarcely ceased to burn. How he
exe'uted his trust was a myttery until the
J) on Agt, of New York, rose and explained an
follows: "Mr. Thomas A. Scott, president of
the Pennsxlvania railroad, dropped in at the
mayor's office and said: 'See here, I'll build
you a strong bridge, with doub'e the capacity
of tbe old one. It shall cost 05,000, $10 000
less than the insurance on the buint-d bridge;
I'll sell it to the city for cost price exactly; I'll
Teturn every cent less than 35,001) that it
-costs, and I'll guarantee to have it done by the
first of Jauuary.'
"When the city authorities had recovered
breath this bold propostlon was accepted Mr.
Scott hud anticipated their acceptance by tclt
graphing all over the lumber country of Penn
sylvania as soon as he made his proposition,
ordering the bridge timber to be immediately
cut and loaded upon cars to await orders. The
jnitant the contract was signed he sent dis
patches ordering that these cars be attached to
lightning express trains and whirled toward
Philai elphia. Before Mr. Scott's proposition
had been officially received every bing was
ready. About 1C0 men stood with sans, ham
mers and spikes in their hands on tbe lmnt8 of
the river at the site of tbe old bridge, waiting
"for tbe ordinance to pass, ready to strike the
first blow tbe moment the signal was given.
" It was toward evening on the 5th of Decem
ber when the coutrict was signed, and work was
begun without an instant's d lay and kept up all
that night. By daylight and by tore he s and cal
cium lights. Sundajs and wtek days, in fair
weather nd storm, without an hour's inter
mission, tbe bridge building was canted on un
der the direction of Mr. 'William J. Lockhird,
division superintendent of the railroad. Three
hours les than twenty-one days from the time
the mayor signed the ordinance, or seven days
ahead of time, the bridge was finished and
formally opened to travel. Tbe men who bad
been engaged upon it were then treated to a
Ohristruiis dinner at the railroad depot in West
.Philadelphia, and will be permitted to take a
-well earned rest during the holidays. The
'bridge is a Howe trass, well constiucted ot
white pine, with flooring of oak. The stiuc
ture is 510 feet long, the two end spans being
each 1G2 feet and the center span 21G feet in
length. The truss is twenty.five fett high iu
--the clear and twenty-eight feet from out to out.
The width of the bridge is forty-eight feet, in
cluding the sidewalk, which is ten feet wide."
Magnetic Separation of Iron and Steel.
'Some time ago we called attention to eertain
machines which were employed on the river
St. Lawrence, in Canada, for concentrating by
means of magnetism the ferruginous sand-t so
abundant in those parts, and in which the iron
existed in the state of the native magnetic
oxide of this metal; we now call attention to a
somewhat similar arrangement called a magneto
mechanical separator, which has for its object
tbe separation of iron and steel filings from the
-copper, brass and other filings which accumu
late in the workshops. The machine is the in
vention of Mr. Charles Vavin, and was de
scribed by M. Bouillet at tbe meeting of the 1st
Hay of the Societe d 'Encouragement des Arts,
etc We must refer to the original source for
-details but it may be mentioned that the mixed
filings fall on two cylinders placed one above
the other, and furnished with ringsof softiron,
which are rendered magnetio by strong artifi
cial horse-shoe magnets of iron, placed as
radii. Effective arrangements are made in or
der to render active the entire sarfaoe of the
-cylinders, and a brush of pig's bristles de
taches the adherent filings. It is stated that
the separation proceeds very well, and that a
machine not costing more than 60 is capable
of cleaning half a ton of filings per day.
Judging from the description, however, we
should he inolined to give preference to the ma
chine ued at Quebec, which has already been
noticed in a former report. Iron Age.
Science and the Abts. The Gramme eleo-
F; trio machine promises to become one of the
f; moat valuable discoveries of modern times.
This machine is now under the control of Mr.
"Werderman, of London, by whom it is gradu
ally but surely being introduced into practical
use, and bids fair to work quite a revolution
in several Important branches of industry.
The greatest electro-plating house in the
world, Christofle & Co , of Paris, use ten of
these machines, and no others. It is claimed
that by its use aluminium may be maie on a
large scale, and at but a moiety of its present
ost. Potassium, sodium, magnesium and cauB-
tio soda can be produced at a fracion of their
present cost. Of its ultimate employment for
telegraphing and general use for light houses
there can be but little doubt. But it is asserted
that one of its most profitable uses will eventu
ally Da tne reduction ot reiractorv ores, sucn as
', sulpburets of gold and silver. And it is also
nopea mat ii may yet oe prontaoiy applied to
the reduction of iron ores. Iron may be pro
duced quite free from sulphur, phosphorus and
other imparities,' so that steel may be produced
directly from the smelting furnace.
Scientific Bubveis. The Secretary of the
.- Interior, in his annual report, says: " The re
' snlts of the caolosical and ceotmohical survev
of the Territories, conducted daring the past
session by Messrs. AUjaen ana roweii, under
the direction of this department, will, it is be-
J lieved, equal in interest and importance those
