PROPELLERS.

To THE EDITOR Of THE SUN.
SM.._ my at!ention has only within the last few days been
called to a letter which appeared in your Journal of the 11th
of June last, and sce.fned " Macaroni." I hope you will not
consider it too late to admit a few observations on the same
subject as that letter refers to, more especially as it is one of
great public importance.
Colonel Maceroni states that in 1827, he submitted to his
late Majesty (then Lord High Admiral), a model of a
plan for propelling vessels, exactly on the same principle
as that for ultieh Captain Ericson, jointly with Mr.
Uraithwaite,-obtLined a patent; but that his Royal High-
leoa never gave him either employment or encouragement.
Pe also seems to consider a remark of Mr. William Clayton,
In yot kr paper of the 4th of June, as alluding to Captain Eric-
aftnes Propeller, whereas, in fact, it was more applicable to the
efl Patetnted plan of Mr. not Ilythe. The highly gifted
Djn'el Deems t o think he was well treated by the Royal
oke, because his Royal Highness did not then realize his
sanguine ectatns. Mect, therefore, now is to
Inform exp
Colonel Maceriooni, that several years before he sub
flitted
his plan to the Royal Duke, a very ingenious person,
laf the name of Shorter, took out a patent fur a Propeller, on
the very same principle as that of Colonel Maceroni ; and
plan, if not formally laid before the Lords of the Ad_
stir I,lty, was at least seen and examined by some of the
Metrebers of the Board, but was not considered worthy of
adopcon. The same Mr. Shorter subsequently applied his
invention to a small boat oil the river Thames ; he also con-
structed a large apparatus, on the same principle, to be placed
In the stern of a vessel, to be worked by the action of the tide,
the abject of which was to give motion to a number of buckets
to raise g av el from the bottom of the river ; neither ex-
periment, howes,er, was found to answer.
Respect for the memory of his late Majesty prompts me to
Make this statement,- in order to repress ally unfavourable
sentiment that might be induced by Colonel Maceroni's letter,
under an erroneous ()pinkie that the late Monarch was not suf-
*eiently attentive to the interests of the Navy.
I would also beg leave to add, that the practice of using
!the screw on the action of inci!ned planes as propellers, has
ven long known to the Government and the country, not in one
Int area only, but in a variety of shapes; but in all cases the
in fx,..essive speed With which the propeller is required to revolve
0, rder to get adequate effect from oblique action, has caused
them to be discountenanced by scientific men.
Alti'lough the subject of this letter may not be particularly
interest ing to tee general reader it is one that is regarded
as of rat 'ch importance, b engineers, and particularly so in
the norti% of England Manchester, Liverpool, &c., where
your excallent journal has so extensiveexei a circulation, and its
insertion, Therefore, without g further controversy,
would be deemed a public benefit. tin-
