FIELD-LANE RAGGED SCHOOL AND DORMITORY.—
Yesterday, the Archbishop of Canterbury preached a ser-
mon in aid of the feuds of this institutton, on which occa-
sion the church of St. Sepulchre's was crowded. This is
the largest institution of the bind in the metropolis, giving
constant assistance to between 900 and I,OIM persons. The
total number of destitute relieved from the funds during
the past year was 3,000, includinq those entirely destitute
who have availed themselves of the night rcluge. 251.12 e.
L was collected after the sermon.

EXPERIMENTS IN SCREW PROPELLING.

POWISUOUTH, Fan. 12.
The experiments with Messrs. Swayne nod Se-
vin's new propeller (Griffith's patent) have been continued
during the week on the Fairy, royal yacht, over the mea-
sured mile at Stoke's Bay, and having terminated to-day
we now give the g I results obtained out of a great
number of runs made with the strew blades at different
pitches or angles. These results have elucidated some
valuable and important points in screw propelling. The
ordinary screw, including tho■e for the Agamemnon and
Duke of Wellington line of battle ships, hid been made up
to the present time without any provision for altering the
pitch to meet the variations of winds and currents, to
which all seagoing vessels are subject. They have thus
been deprived of that which now appears the most valuable
feature of the screw—via., the power of adapting it to meet
every contingency. So difficult does it appear to be for even
the most experienced engineer; to determine for different
vessels the correct pitch to make the screw, that it is the
custom in the navy to construct the second or spare screw,
which every vessel carries, of a different pitch to the other ;
and it seems to be quite a matter of accident whether the
one or the other has the right pitch for the ship. This re-
mark applies equally to the screw vessels in the merchant
service.

During these experiments on the Fairy the pitch of the
new propeller was repeatedly altered to test its effect, end
so simple is the arrangement for doibg this, that it only
occupied three minutes on each occasion.
On reference to the table of experiments, it will be seen
that with the new propeller the engineer can control the
speed of his engines at pleasure, by increasing or reducing
the pitch of the screw, so that, in a fair wind, by increasing
the pitch, the full power of the engine., working only at
their proper speed, may be exerted in effectively propelling
the vessel, instead of consumii g fuel in driving round the
engines to no purpose ; and again, in going head to wind,
by diminishing the pitch the engines can be made to give
out their utmost duty with a cortaiuty of effocthally pro-
pelling the vessel ; and in cases where it is desired to econo-
mise fuel as much as possible, the pitch of the screw may
be increased, to reduce the revolutions of the engines, to
any extent, and the results of the present experiments show
this may be done with great advantage, and no doubt
under canvas would give extraordinary results.
• • " - •

The large central ball of tho new propeller gives ereat
additional strength, and afforus the opportunity of con-
atrurting within it this very strong, and at the same time
most simple and• effective arrangement for altering the
pitch of the blades, and feathering them parallel to the
shaft when the ship is under canvas only, to which so much
importance has lately been attached in reference to the
Australian cad East India steamers.

In the event of the fracture of ono of the blades of th e
screw, which not unfrequently ocenrs,the patent pmpeller is
'caddy repaired by shipping a new blade, weighing net
more than one-sixth of the whole weight; but with the
ordinary screws, which are out in the piece, the breaking
of any part is fiital, and involves the necessity of making a
new casting; simple as this difference may appear, it is not
unimportant in large vessels with braes screws (such as are
universally used in the navy) weighing eight to ten tons,
and now worth 2001. per ton.

Yesterday the last series of experiments were made with
Griffith's propeller, when a number of naval officers were
on board, including Capt. Crispin, Capt. Stevens, Mr.
Baker, inspector of steam machinery afloat, Mr. liartree,
of the firm of Messrs. John Penn and Son,
the makers of the engines, Mr. Smith, of screw
celebrity, and the new screw was represented by Mr.
Bovill and Mr. Griffiths. The vibration arising from the
ordinary screw was entirely dine away with, to which
much importance was attached, as in la:go vessels this seri-
°wily impairs tbeirstrength and creates great leakage in the
after part.
- - - -

It will be seen by the tables that when the screw woe
put at 10 feet pitch the engines could only make 30 revolu-
tions per minute ; notwithstanding this great reduction in
the power employed, the mean speed of the vessel actually
obtained was 11.733 knots, a quarter of a knot lees than was
obtained with Fairy's beet screw, 12.100 knots when en-
gines running 331 revolutions per minute ; thus saving in
power, wear and tear of machinery, and fuel about 25 per
cent. When it wee desired to increase the speed of the
vessel the pitch of the new propeller was diminished, the
revolutions of the engines regularly increasing with every
reduction in the pitch, and at seven feet pitch the engines
made 42 revolutions per minute, and the mean speed of
vessel reached 12.631 knots per hour.
In making this comparison between the ordinary screw
and the new propeller, it must be borne in mind that the
Fairy is the best screw steamer afloat, and that her
present state of excellence has been obtained after
trying, for the last few years, every kind and form of
screw, and the one used on this occasion against the new
propeller was a fine polished brass one, and considered
the perfection of a screw ; the new propeller was simply an
iron one, and the first attempt made against the Fairy
screw, considering the results obtained on this occasion by
the patent propeller, which must be manifest to every one
acquainted with the subject, there can be no doubt that a
still greater speed and perfection will be arrived at.

The dairy went out again this 111 orn fog with her own
screw, we believe at the wish of Messrs. Penn and Mr.
Smith, to see if they could not, on a second trial, beat the
patent propeller. She has just returned, and we understand
they have again failed to come up to the new propeller.
