NAVAL INTELLIGENCE.

PonTamoular, TUESDAY.-The Janus steam-sloop, on the
design of Vice-Admiral the Earl of Dundonald, went out
yesterday morning with her noble designer on board, also
Commander Caffin, of the Scpurge, and Mr. Taplin, machinist
of this dockyard, to make another trial of her engines upon
the rotatory principle. She left the jetty at a quarter before
ten o'clock, and proceeded slowly out of harbour under steam,
but not with her full power on. The Rattler, screw steam-
sloop, Commander Smith, followed soon after, to attend upon
her in case of accident. The Janus was lightened of every-
thing which could safely be dispensed with, consequently
her draught of water was so reduced, that she was enabled
to cut across the Spit bank, which shortened the distance
considerably in making out; -whereas the Rattler, although
going at but little more than half speed, and compelled to
round the anchorage of Spithead, gained so quickly upon the
Janus, that she gave her the go-by at the Lazaretto
off the Motherbank, where :soon after the Janus was com-
pelled to lie to to screw up some of her machinery,
which had become deranged. Both vessels then steamed on
for Southampton, where they moored for a short time, and
then started on their return. The Janus, however, met with
her usual luck, and broke the chain of her starboard wheel
on coming eown the Southampton: Water, which compelled
her to relinquish working the engine on that side the vessel,
and hoist sail to assist her on her way home. She came into
harbour about six o'clock, and the Rattler about half-an-
hour before her. On this trip the greatest speed made by the
anus was 6 and 6 knots. She started with 11i revolutions,
which increased to 16 per minute. Her speed under steam
alone was 6 and 6. The result of the trial has proved that
the Janus cannot be worked upon, the rotatory principle
safely at present, nor long without disarrangement of the
machinery. She is, of course, now hors du combat.

The Retribution steam-frigate, Captain V Lushington, is
being fitted with a connecting-beam to strengthen her paddle-
boxes. She will be ready for sea in a few days. She has 520
tons of coal in her bunkers.

The Alarm, 26, Captain Frankland, arrived at Madeira,
from Spithead, on the 31st of December, en route to join the
squadron under Vice-Admiral Sir F. Austen, Commander •
in-Chief on the West India and North American station. A
private letter, dated " Madeira, Jan. 4," says, "We arrived
here on the 31st of December. We experienced a most
awful gale in the Bay of Biscay, which lasted three days,
which we weathered in most unprecedented style, not strain-
ing a timber, nor carrying away any portion of our gear,
which, considering this is the first trip of our craft, is very
much to the credit of that much maligned officer, the Sur-
veyor of the Navy, on whose design I believe we were
constructed. No casualty of any kind happened, which is
more than astonishing, considering the terrific weather we
encountered. We are very easy in a sea, and in all other
respects a most excellent ship. We sail to-morrow, the sth,
for Bermuda, to relieve, it is said, the Eurydice, 26, Captain
G. Elliot, whose time expired in February. We are all well
on board."

--wri)„,DAy._rne Janus, having adjusted her " wrongs,"
left the harbour tbis morning about nine o'clock to make
another trial, it being asserted, that if she can make 20 revo-
lutions per minute she will succeed. The Rattler again at-
tended her.
