DESCRIPTION OF A NOVELTY IN MARINE ARCHI-


lecture FROM WHICH GREAT SPEED IS Ex-


PEcTED.


PoUGHKEEPsIE August l. 1879.


Persons driving to the ferry landing at this city
taking tour of inspection along the river front
have been mystifed at curious structure on which
many workmen are planning and hammering To
the uninitiated it seems like misshapen boat with
hole through the middle. and even to those learned
in the lore Of cstamarans and other curiosites Of
river architecture the vessel anomaly is in
fact pure experiments steam catamaran built for
the purpose of obtaining greater amount Of speed
in proportion to the outlay Of energy than has yet
been reached by any vessel that floats. The model
is entirely different from anything ever before de-
signed and is the result of the theories Of Mr. Will
lam T. Merritt, the owner and the practical expe-
rience of George I. Polk. the builder In some re-
spects it is similar to ordinary catamaran, the
the halves being placed about fifteen feet apart and
boarded perpendicular sides being exactly par

feet and length 20. The water. Of course, flows
through the straight middle space few feet below
the deck Such vessels usually very long aud

ing. In England recently two ordinary hus were thus

and its simplicity is expected to insure success. The
vessel will be launched in day or Two. The name

she will make thirty miles hour. At all events

to Newburg to Ward. Stanton & Co.'s dock where
her engines will be put in. Mr.. Merritt is gentle
man of large means and intends to give his now in
