-Albemarle County, Va, yearly ships
supply of Albemarle pippins to Queen
Victoria. This famous apple can not be
produced elsewhere than in Albemarle
county, losing its distinctive flavor il
grown in any other soil. ....
The rice paper of commerce is not
paper grown from rice, as its name
would imply, but is the pith of certain
plant cut spirally with a very sharp
knife, opened out into sheets, and
pressed flat, when it is ready for the
market.-Chscago NeWs.
dispatches, from Calcutta report
that the Attock bridge across the Indus
in the Punjab is nearly completed, and
that trains are likely to run over it by
the 1st of May. This will give India an
unbroken line of railway from Calcutta
to Pershawur, a distance of some ! 900
miles. ''as..t
Frank Kittredge, of Danville, VT,
has constructed model for a new steam
engine, whose chief distinction is that it
does away entirely with the piston
movement. Mr.. Kittredge's engine con-
sists of deep trimmed wheel. with
movable floats therein, something on
the plan of turbine water-wheel, and
the steam is discharged against the in.
closed wheel, which he claims will furn-
ish steady and continuous power, and
more of it than can be procured from
the piston movement. f.f
Industrial art now employs the
skins of certain sharks in jewelry, as for
sleeve buttons and the ike-these, when
dried and polished, almost equaling the
choicest stones, and greatly resembling
the fossil coral porites. The vertebrR
of the shark are always in demand for
canes. The opening filled with mar
row during life is for this purpose fitted
with steel or iron rod, the side open .
ings are filled with mother-of- pearl, and i,
when polished, the cane is decided or

In an article published in one of the
German scientific journals on the effect
of the color of glass bottles on the
liquids contained in them, some inter-
esting facts are stated. 1t appears from
this that liquors contained in colorless
bottles, when exposed for some time to
the light, acquire disagreeable taste,
Notwithstanding the fact that they may
have been of superior quality before be-
ing so treated; liquors contained in
brown or green bottles, however, remain
unchanged in quality, even if exposed
to direct sunlight. Since, then, the re-
suits in question are due to the chemical
action of light, it follows that red,
orange, yellow, green or Opaque bottles
are essential to the preservation of
liquors, while colorless, blue and violet
ones are to be discarded.
Among the various uses to which
electricity may be put there is one of a
very practical nature, which promises
to effect very great saving of property
and life. 1t consists of an arrangement
for the immediate stopping of an engine,
by merely pressing a button similar to
those by which electric bells and fire
alarms are sounded. This button may
be placed at any distance from the en-
CINE upon which it acts, and the invent
or proposes that number of such but
tons should be placed throughout the fac
tory or elsewhere where the apparatus is
in use. The principle of the Continuance
depends upon the action of an electro
magnet upon the stop valve of the en-
gine.-Chtca00 Tribune.
