A NEW FEATURE N MARINE ARcHtrECruRE
Several years ago when Mr.. Thomas WiHaa5 nro.
jected his wonderful cigar ship, the attention Of
the maritime world was excited for tie result of
his invention, which he is still prosecuting, BRt
before that is perfected another invention has been
given to the world by Mr.. George F. SNYDER of
this city, which promises to be still greater won
der than anything that has yet appeared upon the
face Of the waters, not excepting even the appli.
cation of steam by Robert Fulton for the propuI.
sion Of vessels. The vessel invented by Mr.. Sny-
der is cylinder, and has rotary motion.
working model of the vessel is now lying at the
shipyard of Messrs Brewster Il Potter, at Canton,
and the trials made with it have been entirely sat
islactOTy, a speed of six miles per hour having
been made by hand power. a stated before the
vessel is a cylinder, through the center of which
passes shaft, which is stationary, and supports
the decks for freight passengers and machinery
and which remain in the same position whatever
may be the motion of the ship. In the working
model there is a cog wheel in the center of the
lower interior surface, working into a cog which
entirely belts the interior, and is the motive power
pr0pelling the rotary progress through the water
1t is now designed to build vessel of forty feet
diameter, into which will be placed two steam
engines of fifty horse power each, and with that it
is expected to make speed of from forty to fifty
miles an hour. That vessel will draw, when lying
still not more than ten or twelve inches of water
and the draft will be reduced when the machinery
| is put in motion. On the outside surface will be
paddles set two feet apart, besides which there will
be four kees, one at each end, and two at the cen
| ter. These keels are intended TO prevent the
sci from drifting in high wind and to protect the
paddle in the event that she should strike upon the
| bottom. The new "TeVOlYer,' as the style Of yes
sci has been called, will be of three hundred tons
burthen and besides freight will have capacity for
about three to four hundred passengers, Her
steering apparatus consists of a small enclosed
boat, the bow of which is worked by pu!lies at.
tached to two beams running from the center shaft
around to one side the stern Of the ship, and it
is claimed that she can be turned in the space oc
cupied by her length in the water. A number of
gentlemen Of this city have taken hold Of the thing
and will push the new vessel to completion, so that
she may be ready to make trial trip on the 4th
of July next. A model of the new wonder is at
the Office of John s. Selby, No. II Second street
where it may be by those who feel an interest
in the advancing sciences of the age. The small
draft Of water will render the vessel if successful
of inGalculable value for the navigation Of the
rivers which penetrate the heart Of the great West
while its speed far outstrps that of any other ship
The same principle may be applied to land vehicles
on ordinary roads, and may be guided as easily
as those drawn by horses Some prominent
engineers who have examined the principle de-
clare it feasible, and much curious desire will
await the adyent Of the new vessel in the Pa
tapscO.
