7'HE NAVY.

VALETTA, May 14.—There have been several
movements of men-of-war during the week. Her
Majesty's screw lino.of-battle ship James Watt, 89,
Capt. Coda, which sailed for England to be paid off,
on the day of the departure of the last mail, took
with her the following passengers :—Lieut. Irvine,
Lieut. Dickson, and Capt. Tyacke, 22d Regiment ;
Sergeant F. Thompson, also of the 22d; Mr. Homan,
Mr. Littlejohn, Mrs. Hallett, and 13 soldiers. Her
Majesty's paddlewheel frigate Magicienne, 16, Capt.
his Serene Highness the Prince of Leiningen,which
has recently joined the Mediterranean fleet, left on
the same day (Bth inst.) for the Levant. Her Ma-
jesty's screw corvette Gannett, 11, Commander the
Hon. M. H. Nelson, arrived on the 12th instant
from Beyrout in 15 days, and leaves to• day or to-
morrow morning with a mail for the Commander-
in-Chief, at Corfu. The screw frigate Amphion, 36,
Capt. Gordon, which has been in the hands of the
dockyard, is under orders to proceed to Candia.
Commander Piers, R.N., to command the Firebrand,
6, and Assist.-Surg. Bayfield, R.N., arrived here by
the Peninsular and Oriental Company's steamer
'Vanilla, on the 7th inst., from Southampton, and
the Earl of Harrowby, the Hon. G. Ryder, Colonel
Sargent, 3d Buffs, and Col. Hallewell, staff, were
among the passengers by the Ripon for England,
the two latter on leave. Capt. R. Rouse, 15th Regi-
ment, Capt. J. Blacker, and Capt. Drought also left
for England a few days ago in the Palestine. A
good many officers of the garrison have lately pro-
ceeded home for the object of witnessing the Great
Exhibition. The Turkish Government steamer
Malakhoff, Capt. Selim Bey, arrived here on the
Bth inst. from Constantinople. having on board his
Excellency Mustafa Bey, who is proceeding to
Tunis in this vessel to present the decoration of the
newly created Order of the Osmanie in brilliants,
and a jewelled snuffbox, which his Majesty the
Sultan has conferred on his Highness the Bey of
Tunis. She left a few hours after arrival for her
destination, having only put in here to replenish her
coals. Her Majesty's screw gun vessel Surprise, 4,
Commander W. H. Whyte, came in this morning
from Corfu, with dates from that island to the 12th
inst. A letter I have received of that date says:—
Her Majesty's ship Marlborough (having on board
Admiral Martin) steamed into harbour on the Bth
inst., and report says she will remain on and off for
the summer months at this roadstead. She found
the Queen;B6, Trident, 3, and Surprise, 4, here, the
last leaving this day with mails for your island,
Gibraltar, and England. The Queen proceeded under
steam yesterday to Athens, with the Hon. H. Elliot,
the new Ambassador to Greece, who arrived here by
the Austrian steamer on Saturday. The greatest
activity prevails on the part of the Turkish Go-
vernment in sending troops to Montenegro, and
steamers crowded with troops arrive here almost
daily. They are allowed to land, and behave
themselves creditably. The men seem fine-looking
fellows, and better fed than the Turkish troops who
served in the Crimean war. The Royal Artillery
have orders to be ready to fire a Royal salute for
the Viceroy of Egypt, who has been expected en
route to Europe for the last week. General Sir J.
Inglis, K.C.8., accompanied by Quartermaster-Ge-
neral Herbert, Col. Wright, R.A., Col. Wynn, R.E.,
Major Young, Military Secretary, and Major Hamil-
ton, aide-de-camp, returned from the Southern
Islands on the I)th inst., the General having made
his half-yearly inspection of the troops. On his
landing he was received by the usual salutes. The
Icarus, 11, arrived from Malta on Saturday last.
Tho Trident leaves to-day for Zante and the other
islands, with the Bishop of Gibraltar, for the pur-
pose of holding a confirmation, his lordship having
already done so here on the Bth inst. when some 60
soldiers and a few English inhabitants were con-
firmed.

A paragraph in our naval intelligence of
Saturday relative to the Queen's regulations and
Circular orders was so far incorrect. The Queen's
regulations of 1844 and the Circular subsequently
issued have merely been called in, as a new edition
of these regulations and Admiralty instructions has
been issued to the fleet.

The Shannon, screw frigate, Capt. Wainwright,
resumed her experimental screw trials at Portsmouth
yesterday, under the supervision of Capt. Broadhead,
commanding the reserve at the port. The screw
tried yesterday was the ordinary pattern, or
"common" screw, as it is termed, with its leading
and following edges cut off. Coals were taken on
board the ship prior to leaving the harbour for the
trial, equal in quantity to those burnt in the trial
of M. Mangin's screw on Saturday. The ship was
trimmed to the same draught of water line, the
same stokers were employed at the fires, the same
men were placed at the wheel, and the weather
proving equally fine yesterday with that of Satur-
day, both trials took place under, as nearly as pos-
sible, the same conditions. Six runs were made at
the measured mile, with the following results as to
time and speed :—First run, 5 min 1 sec, 11.960
knots; second run, 5 min 58 sec, 10.055 knots;
third run, 4 min 52 sec, 12,329 knots ; fourth run,
6 min 6 sec, 9.830 knots ; fifth run, 4 Mitt 55 sec,
12.203 knots; sixth run, 6 min 12 sec, 9 677 knots.
The mean speed of the whole was 11.062 knots. In
the first and third runs the revolutions of the en-
gines were 57; in the second and fourth, 58; and
in the fifth and sixth, 671. The pressure of steam
varied from 191 b to 201 b, the vacuum, forward and
aft, being 25 inches. The ship's time was next
taken in making a complete circle both to starboard
and port, the helm being in the first instance put
to port, when the rudder was hove over to an angle
of 13 deg in 29 see, the half circle made in 3 min
and 35 sec, and the circle completed in 7 min 43
sec. With the helm to starboard the rudder was
hove over to an angle of 151 deg in 28 sec, the half
circle made in 3 min 19 sec, and the circle completed
in 7 min 33 sec. The revolutions of the engines
ranged from 50 to 54. The vibration caused by
the working of the screw was less yesterday
than on the previous day with the Manginy
but it was rather more than was experienced
with the Admiralty screw on the 16th, the first
trial of the present series. The next trial will
be made with a screw of four blades, to be suc-
ceeded in turn by one of six blades. The dimen-
sions of the three screws already tested are as fol-
lows :—The Admiralty, or common screw, with its
leading corners cut off, tried on the.l6th inst., had
a diameter of 18ft, and pitch of 23ft 10in. The Man-
gin screw, tried on the 17th inst., hnd a diameter of
18ft, and pitch of 25ft. The common screw, with
both its leading and following corners cut off, tried
yesterday, had a diameter of 18ft, and a pitch of
24ft llin.
