ner'ia resp :euns tue application of steam power
10 our ship Clarion" II is not the arcbimedean
screw .hat we are gong to apply, but propeiling
apparatus possessing lar superior quac cation, viz.
Capt. Ericsson's Transversal Ship PropelIsr which
has no other property in common with the screw Of
the experimental steamboat Archime aes, than that
oil tcorh,ng entirely under Dater.
Deeply interested in nautical commerce, we have
watched with much attention the effects of the in
PRODUCTION OF steam power for ocean ma gatiop. AMI
care'eiy Estimated the probable results Of the APP
Phcati"n OF steam To our nrvalied Ame nae d.
ct ships, and we have arrived AT the concius ion
sat an auxiliary steam power capable of propel,ing
our ships at from seven to eight miles per hour in
calm weather, will effect revolution in commerce
far greater and more beneficial than the introd 40
ton OF steam ships. With these views we have me-
ticed with much interest the development Of the
intention, which we now are applying to the Ella
ron We were present at this first trials of this shin
propeller IN England some time since the result o(
which, corroborated by further trial Of practical
minds beyond doubt.
In endsavoring TO introduce an improy eneLt 10
Navigation so much needed, and in the success Of
wnchs great An interest, both private and public,
AZ stake, We have been at some pains to in
the respective claims of the al plans and find
that there is so great difference in the practical
etity and economy OF the two as to leave no room
Tor hesitation As to preference.
The screw of the "Archimedesr work. in q LARGO
square opening in the g dead wood, of the yessei
and requires if applied to ordinary ships, an entiro
hazardous -
to the strength ofthe after part Of the ship IN ad
dition to this the screw of the Archmedes is VIC
ed at such great speed (exceeding one hundred
revolutions per mnute,) that the Of heavy
tricate combination Of cog wheels is required TO
give the necessary velocity, the speed of the Arch
mcdes' engines being thereby actually multiplied
five times Without pretending to mechanical
knowledge, we assert confidently that such high
speed must be very objectionable in practice, and
cannot fail to be attended with loss of newer. The
excessive velocity Of the screw. in particular must
be productive Of much wssteful resistance in Qoinc,
| through the water. We are supported in this opiD
nicn by the result Of the late trial of the Archimees
a, Liverpool against the tug William Guustap in
which the latter, with engincs Of less power tsrnet
the Archmedes astern at the rate of several niles
per hour against the exerted whole force Of her SUI
perior eng inc power.
The transversal chip propeller, which, FROM ID,
motion being transversey to the line of the kee ~
so named in eontradstinction to the paddle wheel
may be applied TO any ship without the least
ton to her stern. 1t consists Of thin broad heop,
made OF wrought irsn, supported by arms Of the
same material, and attached to a central shaft which
passes through the run ofthe ship. To the crc UNI
| ference Of the said heop are attached series of
plates (spira planes) also Of wrought iron, placed
| at an angle, the whole weighing under 900 pounds
two OF these propellors, revolving in contrary d-
rections are applied, one on each side of the stern
pos, their axes being supported by iron braces Sc
cured thereto. The effect of the current Of water
produced by the motion of the propeller will, 40
rudder. The distinguishing feature, however, OF
the transversal ship propelor is that the contrary
movement is Effected and the ship propelled at any
required speed, without the use Of cog wheels inc
total weight Of the machinery for the Clarion, con
sistng OF two engines of 80 horse power each, boil
ers, propeller, &c. will not exceed 70 tons All will
be ready to be placed on board by the end Of next
