SAN ANTONIO is rapidly becoming the
great wool market of Texas.
PENNSYLVANIA is no longer to have
a practical monopoly CT the business
of furnishing the world with cheap
petroleum. The oil field crosses the
State line, and there have been lately
several strikes in Allegany County,
N. Y.
LAST year not a pound of cream of
tartar was imported. A few years ago
millions of pounds came annually from
England and France. Manufacturers
at home now supply all that the country
needs, and prices are thirty per cent.
lower than formerly.

Guardian, the orange crop in that Sec
ton will be exceedingly slim this
year. 1t says the dry weather caused
many of the trees to drop both fruit
and leaves, but since the late rains
they are putting out new foliage, and
in all probability may bloom again.
In the future most of the breadstuffs
exported from this country to England

The English millers, it is reported, are
discussing going out of the business,
as the new American processes under

NJ. MALEzIEUx, of Paris, recently
delivered an address on the public
works of the United States, in which
he complimented American engineers
upon their skill in building bridges of
large span, and obsel we'd that other ma
tions might borrow many useful hints
from them in regard to the use of COM
pressed dir in laying foundations.
In the workshop of the railroad from
Moscow to Mini, the tires of the wheels
are not expanded by the direct action of
fire, but by hot water, before being put
on the wheels. With the assistance of
a movable crane they are plunged into
metallic cistern containing the water,
which is kept boiling by means of
steam from a boiler close by. An inn
mersion for some ten minutes is found
to expand tire sufficiently to enable
it to pass around the wheel. The heat
is found to be more uniform and the
contraction more regular than when q
tire is heated by fire in the usual way.
An alloy of peculiar beauty and
adaptation, as substitute for silver, is
now employed in one of the most
celebrated jewelry manufactures in
France. It consists of sixty-five parts
of iron, twenty-three of nickel, four of
tungsten, five of aluminium and five OF
copper. The iron and tungsten are
melted together and then granulated,
the water into which the mixture ruins
for this purpose containing one kilo-
gram of slaked lime and one of car
Donate of potash per cubic meter. The
nickel, copper and aluminium are also
melted together and granulated by rum
ming into water containing the same
proportions of lime and potash-care
being takor ''rr;ng the melting to cover
the metals contained in the two cruel
bles with flux composed of one part
of boric acid to one of nitrate of potash
or inter. In the crucible containing
the aluminium and copper is placed .
lump of sodium of about two grains in
weight when treating five kilograms of
the three metals-nickel, copper and
aluminum-together, to prevent oxida-
ton of the aluminium, and charcoal is
also added to prevent oxidation of the
copper. The granulated metals are
dried, then melted together in the same
crucible in the proportions above indi-
Gated, and we'll stirred, after which the
alloy is run into ingots. 1t has the
same appearance as pure silver.-N.
