ALLEGANY CoUNrY.-From the Cumberland Tele-
graph: The work on Dams Nos. and 5, on the
Canal is progressing vigorously towards compile
ton.
The coal shipments this year up to this time, are
in excess of those of the corresponding period of
last year about sixty thousand tons. This increase
has been transported over the Canal. The ship
ments by railroad have considerably diminished.
1t is understood that party of enterprising gen.
temen of this city, in conjunction with others from
Boston, contemplate erecting early day in this
city an establishment for the manufacture of Para
fine or Coal Oil, from the coal of this locality.
Governor Hicks has appointed Mr. G. Lewis
Shryock Justice of the Peace for election: dis
trct No. 7, to supply the vacancy occasioned BY
the death of A. T. Crabtree.
In consequence of the late rains the Potomac and
Mills creek are in good condition, and there is now
an abundance of water for canal navigation.

Andrews, the proprietor of the Cumberland Muse

the remains of a gridiron, fsh-gig, nut cracker,
stIrrup, and two cannon balls. which were poughed

NEW CONSTRUCTION OF SH1Ps.-A new plan in the
construction ships is proposed by an English in
ventor the popularity of which consists in building
them of combination of iron ribs and wooden
planks, fixed together by bolts and screws and fur
Their cemented together by composition or glue,
SO that the iron ribs and planks firmly combined
together in one solid mass. .-. ID. I5.t--..
The plan further consists in connecting the decks
OF SHIPS or the main timbers supporting them with
the keels, by means of lattice other framing by
which considerable stiffness and strength are OBJ
tained-the decks, framing, and keel being firmly
connected together, and constituting a girder run
nlng through the ship. The ribs may be formed
either of rolled bar angle iron, or iron a number
OF such iron ribs being placed at short distances
apart, with the head of the T. or the fiat face of Inc
angle iron rib presented towards the exterior each
rio being bent into the required form. In Iaroe
vessels, when two or more lengths of bar are re-
CURED Tor one rib, they are to be welded together
or Jonted by lap joints or plates the Several
rios being SO arranged that the joints of no two adj
Joining ribs should be close or nearer to each other
The skeleton of the vessel being thus formed
wooden planks, previously creosoted according to
process peculiar to the inventor are riyeted bottled
or screwed to the exterior of the iron Whale
