Naval and Military Intelligence.

Yesterday the Duke of Cambridge visited Canter-
bury for the purpose of inspecting the cavalry depot
and the riding establishment stationed at the garri-
son in that city. His royal highness, who was
attended by Lord George Paget, Inspector-Gen. of
Cavalry ; Capt. Fraser, as Aide-de-camp ; Lord
William Paulett, Sir Robert Garrett, Gen. of Divi-
sion ; Col. Cox, Adjt. of Division ; Col. Curzon,
Sir James Yorke Scarlett, and other staff officers,
arrived at the barracks about half-past 9 o'clock, and
proceeded to inspect the married men's quarters. He
then proceeded tcT the drill field, where he was re-
ceived by the troops in complete marching order,
under the command of Col. Custance, C. 8., com-
mandant of the garrison. Having marched past, the
troops performed a variety of manoeuvres and
marched past in parade order, when they received
the commendation of his royal highness for their
steadiness of drill. The hospital was next visited,
and the internal arrangements of that institution
were spoken of in terms of approval. Proceeding
from thence to the riding school the Duke of Cam-
bridge inspected successively the establishment rides,
under Major Blenkhorn, superintendent of the rid-
ing school. The whole of the garrison afterwards
paraded, dismounted, in the Cavalry-square, and,
after undergoing a minute inspection, marched past
in slow and quick time. An officers' ride, which
followed•the foot parade, terminated the inspection,
his royal highness expressing himself to the com-
manding officer as highly gratified with the entire
proceedings. After partaking of luncheon at the
officers' mess, the Duke of Cambridge left the bar-
racks, and afterwards started by train to London.
A model of the sea-going turret-ship, designed
by Mr. Scullard, the Chief Admiralty Draughts-
man at Portsmouth dockyard, to meet the views
of Capt. C. P. Coles in the construction and fitting
of a vessel carrying one turret mounting two 600=
pounders, as a competitive vessel with Mr. Reed's
Pallas, has been completed at Portsmouth yard and
forwarded to the Admiralty. The model has been
greatly admired on account of the beautiful form of
its hull, which gives promise of high speed, with su-
perior seagoing qualities, the clear manner in which
the details of hull, fittings, and rig are shown, and
the very careful workmanship.
The Octavia, 39, screw-frigate, Capt. C. F. Hill-
yar, one of the experimental fuel-saving squadron,
goes out of Portsmouth harbour this morning, pre-
paratory to her trial at the measured mile and cruise
in the Channel.
The wooden screw corvette Pearl, 1,460 tons, 400-
horse power, was yesterday undocked from No. 5
dock in Portsmouth yard, where she has been nearly
rebuilt, and placed in the basin to bring forward for
commission.

The Monarch, sailing liner (old target ship), was
Yesterday morning towed from Portsmouth toWhite's
Medina Dock and Building yards at Cowes to be
broken up.

The formal opening of the North Inlet, or No. 11
dock, of Portsmouth yard will take place this morn-
ing by the admission of the iron frigate Minotaur,
of 6,621 tons and 1,350-horse power. The new dock,
which was designed by Mr. Scamp, Deputy Director
of Engineering Works to the Admiralty, is one of
the best executed works in masonry ever yet con-
strusted in any of the Royal dockyards. When this
morning it has received on its blocks the largest ship
in herMajesty'snavy, there will still be fully Bft. clear
space between the ship's taffrail and the caisson on
the dock's invert, with also an unusually large space
for the workmen under the ship's bottom and bilges
and around her bows and quarters for carrying out
any operations required, even to the extent of re-
building the ship at any future time, should such an
operation ever become necessary. The dock has been
constructed by Messrs. George Smith and Co., of
London, and has been performed with real faithful-
ness of detail. The dimensions of the dock and the
materials, &c., used are as follows :—Length at
floor, 400 ft. ; length at coping, 426 ft. ; width at
invert, 70ft. ; width at coping, 99ft. ; width at
broad altar, 75ft. 9in. ; width at floor, 35ft. The
depth of dock is from coping to floor, 33ft. 10in.,
and from floor to broad altar, 18ft. The depth of
water is in midships, at high-water spring tides,
28ft. 4in. ; on invert, at high-water spring-tides,
27ft.; on invert, at high-water neaps, 23ft. The
materials, &c., used .are :—bricks, 3,750,000 ; con-
crete, 6,5(0 cubic yards ; granite, 135,000 cubic
feet; Portland stone, 26,750 cubic feet; timber,
81,000 cubic feet; and the excavation removed oc-
cupied 57,000
yards. The floor and sides of the
dock as high as the broad altar is built of granite.
From the broad altar upwards are laid, first, three
courses of Portland stone set vertically, succeeded
by four courses of the same kind of stone set back
in the usual manner in steps, the whole capped by
the coping of granite. The introduction of Port-
land stone is to be regretted. The saving in first
cost as compared with granite can be but trifling,
and it will necessarily prove the most expensive
course, when, after the lapse of a few years, repairs
are needed. The dock floor has a fall of nine
inches, with a double water channel to keep it clear
of water.

The following appointments have been made at
the Admiralty :—Commander Thomas S. Gooch to
the Frederick William, for service in the Coast-
guard ; Commander Richard Roach to the Royal
George, for service in the Coastguard ; Comman-
