The Imperial Ottoman screw line-of-battle ship
Kosovas, 80 guns. bearing the flag of Admiral
Edhem Pasha, the Commander-in-Chief of the Otto-
man squadron now lying at Spithead, completed
her screw trials over the measured mile in Stokes
Bay on the 18th inst. most satisfactorily, under the
supervision of Mr. J. Dinnen, inspector of machi-
nery to the English Board of Admiralty, and of the
steam factory and reserve officials of Portsmouth
Dockyard. The ship 'has been recently fitted at
Southampton by Messrs. Maudslay and Field, of
Lambeth, with engines of the nominal power of
700-horses, under the inspection •of the officers of
the English. Admiralty. The Rossova's engine
cylinders have a diameter of 77 inches, with a
length of stroke of 3ft. 9in. The boilers have
about 21 square feet of heating surface per nominal
horse-power. The screw is two bladed, with a
diameter of 19 feet, and a set pitch on the trial
of 20 feet, but it :can be varied from 20 feet to
24 feet pitch, being bolted together on Mauds-
lay's principle. The screw's leading, corners are
cut, as is the custom now with all screw blades in use
in her Majesty's navy, on the Admiralty pattern.
The screw is lifting, and is hung in the usual banjo
frame. On weighing her anchor at Spithead for her
trial over the measured mile in Stokes Bay the
Kossova's, draught of water was 23ft. forward and
25ft. aft, the upper edge Of the screw being then
immersed 2ft. 6in., the ship having 425 tons of coals
in her bunkers, and being otherwise in all respects
complete in stores, armament, and crew, and ready
to proceed direct to sea from off the trial ground if
required to do so. The wind was rather fresh from
E.N.E. with a slight swell over the course. Six runs
were first taken with full boiler power. This gave
the ship a mean speed of 12.028 knots, the revolu-
tions of the engines being, maximum, 70 ;
and mean,
69-833. The mean pressure of steam in the cylinders
was 24-041 b., and the vacuum in the condensers for-
ward, 25-sin., and aft 26-sin. The indicated horse-
power was 3,606.63, or considerably upwards of five
times the nominal power of the engines, a propor-
tion greater than has been achieved at any time be-
fore by any screw line-of-battle ship with the same
nominal engine power over the Stokes Bay trial
course. With half her boiler power, which followed
on her full power trials, the ship attained a mean
speed of 10.655 knots, the revolutions of the engines
being, maximum, 60 ; mean, 59-25. The mean pres-
sure of steam in the cylinders was 16-41 b., and the
indicated horse power 2,117-8. In testing the ship in
turning, when she had been taken off the measured
mile on the finish of her full and half-boiler power
runs respectively, she was found to answer her helm
very readily. At full power she made a half-circle to
starboard in 3 min. 40 sec., and she completed the
circle in 7 min. 16 sec. To port she made the half-
circle in 3 min. 15 sec., and completed the circle in
6 min. 35 sec. With half-boiler power, in turning
to port, she made ibii_half -circle in 3 min. 32 sec.,
and completed the circle in 6 min. 57 sec. In turning
to starboard her time was, half-circle, 3 min. 20 sec.;
full circle, 6 min, 35 sec. The last test to which the
ship's machinery was subjected on her trial was the
facility with which she could be managed in obedi-
ence to orders sent below fromthe upper deck bridge,
and the result of this was as follows :—Engines
stopped, 21 sec. ; ditto started ahead, 27 sec. ; do.
astern, 9 sec. The Kossova is an exceedingly hand-
some vessel, as may be imagined when we state that
she was constructed from the lines of the Renown
line-of-battle ship, improved by the introduction
into them of two or three of the best points in the
lines of the Revenge, the present flagship of Rear-
Admiral Hastings R. Yelverton, C.B„ second in
command of the British fleets in the Mediterranean.

The 17-gun sloop Mutine has returned to Wool-
wich, after a trial at the measured mile, and is
ordered to be prepared for immediate commission.
Her destination is stated to be to relieve the Har-
rier on the Australian station. The Mutine has been
repaired in every compartment, and has been fitted
with a topgallant forecastle as a shelter for the crew.
The same principle, it is stated, is intended to be
carried out by Mr. Reed, the Chief Constructor, in
all ships of that class belonging to her Maj esty's navy.
The last piece of the keel belonging to the old 36
gun frigate Dartmouth was yesterday removed from
the building shed in Woolwich dockyard, the demo-
lition of the ship being now complete. The whole
of her timbers will be again available, and are still
in good condition. The Dartmouth was partially
built when the new system of shipbuilding was pro-
posed by Mr. Reed, and the work was discontinued.

A large number of artisans have been placed on
board her Majesty's screw steam corvette Chal-
lenger, 22 guns, 1,462 tons, 400 horse power, now
lying in the large basin at Sheerness, and recently paid
out of commission by Capt. John J. Kennedy, C. 8.,
at Sheerness, who are repairing and refitting the
vessel again as quickly as possible for recommission.
The depot of the 17th Lancers, consisting of Capt.
Gonne, Lieut. Corbett, Cornets Symonds, Carter,
and Bancroft, and about 110 non-commissioned
officers and men, with their families, will arrive at
Colchester on the 28th from 3laidstone to await the
arrival of the head-quarters of the regiment, now
on its way home from India. The regiment will
replace the 16th Lancers, under orders to leave
England for India in June. Staff-Surgeon Hollo-
way, of the 9th Depot Battalion, has been trans-
ferred to the 10th Depot Battalion, at Colchester,
vice Dr. Williams, and consequent upon the reduc-
tion of the 9th Depot Battalion.
An official notification has been received at
Chatham garrison, from the Horse Guards, announc-
ing that 'to afford greater facilities for the comple-
tion of the number of non-commissioned officers
allowed on the permanent staff of the disembodied
militia, the Secretary of State for War, with the
concurrence of the Field-Marshal Commanding-in-
Chief, has approved the transfer to the militia of
soldiers from the regular army after the completion
of 18, instead of 20 years' service, as heretofore.
All men transferred from the Ist Jan., 1865, will be
allowed to

n to on ckonmilitia service as equivalent to
mcompleting the period which will

his transfer to that on which pensions willbe awarded
on the completion of the requisite period of service :
