O'Clock Wednesday afternoon, this splendid addi-
ton TO Mortimer Livington's Union Line of Havre
packets made her entrance into the waters Of the East

sight of such beautiful vessel gliding majesticaly
from her ways into the water, well worth the
trouble of walk. There a very large assemblage
present to witness the sight.

SUB-MARIsE BoAT-About FIVE months since, In
noticing the progress of arts and manufactures we
mentioned sub marine boat, which bid fair to
pass any thing that the widest magnings would lead
to expect from the genius of the present age
This important invention is the result Of the sppcs
ton of law in physics, on q large scale, by Mons
Alexandra, eminent French civil engineer, which
law establishes the fact that a certain quantity of
compressed air, contained within given space makes
an efficient equilibrium or In other words, balances
the pressure OF water so as TO prevent from entering
the submarine boat be has invented which most ad-
mirably sdapts this scientific principle to the pur
pose desired The ingenious and estimable engineer
who has contrved this apparatus by of It,
descend at will to the bottom OF the sea. or examine
the beds Of streams rivers in direct contact with
their hidden treasures and with the power of working
well Of moving along at his ease for hours and
with perfect safety without suffering
although deprived of all communication either direct
or indirect, with the air We have not space to
enter into minute description OF this intere sting ap
paratus would recommend the civil engineers
capitalists and others who interested in the pro-
gre.s Of science amongst u.s. to examine the model,
which has been constructed by Mr.. Alexandra, who
has had the kindness to give scientific description
of this sub marine boat, which believe is destined
to render to the commerce. and to the maritime in
terests Of the country the most important services
We think that to insurance companies this mschne
will be invaluable in recovering goods merchandise
from wrecks It will also be valuable for laying down
telegraph wires securely rivers sc. For the
mediate and most profitable and may add that
for seeking gold other vausbes lost in wrecks CT
for an examination OF the hidden dangers at the
frances OF harbors &c drafting sub marine charts
IL will be found most important and 1t is our firm con-
yiction, that the sub marine boat of Mons Alexandra
will rank with the apple alton of steam to boats by
Fulton, and be an honor to America while IL should
immortaize the inventor.
