NAVAL INTELLIGENCE.

Rear-Admiral Deans Dqndas, C. 8., M.P., left the
Admiralty yesterday, for Chipping Norton, for a
week or ten days.
Captain Cockburn is waiting at Portsmouth, to
take command of the Rattlesnake surveying-ship, on
her arrival from Sydney.
Dragon, 6, steam-frigate, Captain H. W. Giffard,
left Devonport on Thursday, at noon, fur Lisbon and
the Mediterranean.

Firay, 3, steam-vessel, Commander Seymcur,
completed her defects at Devonport, was paid advance
by the master-attendant (Mr. Henderson), and left for
the coast of Africa on Thursday evening.
Thetis, 38, Captain Kuper, at Devonport, was to
have been put into No. 5 dock. She was painted,
and entered the dock about thirty feet, when it was
seen that the tide ceased to flow, and she was taken
back and moored alongside the jetty to wait till the
morning tide, when it was hoped it would rise suffi-
ciently high.
The Admiralty, at tbeir last visit at Devonport,
inspected a model and witnessed the trial of an inven-
tion of Lieutenant Seccotnbe's (late First Lieutenant
of the Trincomalee), by which the laying out of a
bower anchor, with a chain cable attached, from a
large boat or launch, can be performed with perfect
safety. Hitherto it appears that such operations have
always been attended with considerable risk to lite
and property, from the want of complete command
over the chain in running out over the davit at the
stern of the boat ; but this risk by the above inven-
tion, which is a clutch, clasping the chain, and acted
upon by a lever, will be entirely obviated. In fact,
the chain by this method can be stopped at a moment
when it has acquired the greatest velocity, and of
course can be lowered fast or slow, at pleasure, which
is a great desideratum. The Admiralty were so sa-
tisfied,by its success, that at the trial above alluded to
they paid the inventor a very high compliment, and
requested him to forward the model of it to White-
hall.

PORTSMOUTH, Fain AT.—The Bulldog steam-sloop,

EXPERIMENTS AT CHATHAM.
A number of officers of the Royal Engineers and
officers of Engineers in the East India Company's
service assembled on Thursday afternoon at Bromp-
ton Barracks, and proceeded to a ditch in the Chat-
ham fortifications to witness experiments with six
different kinds of scaling-ladders—the first, the old*
common kind, made of wood ; the second and third
ladders also made of wood, one on • plan by Major-
General Pasley, and the other by Colonel Blanchard.
The fourth, fifth, and sixth ladders are on a new
principle, submitted by Captain Addison, of her
Majesty's line service ; and the sixth was sent to
Chatham from the Royal Arsenal, Woolwich. One
of Captain Addisen's ladders is formed of wrought
iron circular tubes, and the interior filled with wood
two inches in diameter and eight feet long ; the
other is made of wood, with an iron hand along the
outside. The ladder from the Royal Arsenal is made
of wrought iron tube in an oval form, and when
the parts are separated the cross bars or steps, also
made of wrought iron tubes, can be all placed inside
the supports. Captain Addison's tubular ladder has
the cross bars placed outside the tubes, and moving
on pivots, the two supports, adjusted when in use by
two diagonal bars on the other side, can be made, by
loosening the two diagonal bars, to lie close to each
other, and occupy very little room. The ladder is
formed of three pieces, the middle tube being smaller
than the lower, and the upper smaller than the mid-
dle, and are as easily and quickly joined as the lower.
parts of a fishing-rod. The wooden ladders consist
of one of two pieces, one of three pieces, and one of
four piece?, but their steps are axed, and cannot allow
the supports to be placed close to each other as in the
two iron ladders. The experiments commenced
by Sergeant Major Allen selecting six parties
of six men each from the Royal Sappers and
Miners at Brompton Barracks, having each
party as nearly similar in size and strength of the
men as possible, and they proceeded to the ditch.
During several trials the circular tube ladders of
Captainring Addison were put together and let down into
the ditch about 20 feet deep, and the men descended
on itin less time than by the others. The ladders were
also taken down into the bottom of the ditch and raised to
the other side, and the wall scaled several times
with the greatest, activity by the men on all the
ladders, with the exception of the oval tubular ladder,
which, being of equal dimensions throughout its en-
tire length, the six men employed could not raise it
against the wall of the ditch, and it required four men
extra to raise it when it was taken out of the ditch
on the experiments being concluded. The only ob-
jection to Captain Addison's tubular ladder was the
difficulty of drawing it out of the ditch after the
well had been scaled, owing to the projection of
the diagonal bars on the back, but Captain M'Kerlie
suggested the expediency of these bars being made
to move inside, and Mr. Webb, blacksmith, from
Woolwich, who attended on Captain Addison, was
detained at Chatham to have that alteration effected.
