The Boston Submarine Company have been for

vessels at sebastopol agreeabyt contract made at

The Old mode OF raising snnken vessel was to lift
her with chains and scows, which, beside being tedi-
Gus, uncertain and very expensive process has always
been open to the serious objection that precauton
can prevent great injury to the hull by the chains
cutting and crushing into but till the recent
invention of the Gwynne Pumping Engine, no better
in existence could epel the water fast enough from
sunken vessel to overcome all leaks and admit suf-
cent quantity Of air to raise her. This method, as
it can be used by no one else, will undoubtedly enable
the Boston company to raise every ship Of any value
in the harbor of Sebastopo with arapdity ertainty
and cheapness which viii defy competition.
We learn from the Philadelphia Ledger that an ex-
pedton for the same purpose, under Mr.. Gowan, has
been fitted up by capitalists in that city, but whether
any contract has been made is not stated.

OF Missouri to become free State by selling off its
slaves to the Southwest and thus to exchange black
slave owned labor for free white o,cned labor The
money invested in slave property would thus be saved
and, besides land would largely rise in value with
small farms of free labor against large of slave

which means. that it is the interest of st. Louis to
keep open through Missouri all the great lines of
travel to Kansas, in order to fill up that State with
free population, which may do large mercantile
business at its natural outlet ST. Louis. It is seen
from this that in Missouri Atchinson has over

The Southern Democracy, which has heretofore so
heartily conrted the foreign elements in that party
receives here in ST. Louis its first great stab If the
stab only beeds it little, it will make its health
