The time fixed for launching the Plumper was 11.45
A.M., and shortly before that hour the Gallant Admiral,
Sir Charks Ogle, arrived, accompanied by Captain
Milne, one of the Lords of the Admiralty, Mr. Ward,
M.P., Secretary to the Admiralty, th• Commander•in-
Chief of the Garrison, Lord Frederick Fitzclartnce, the
Marquis of Winchester, and several other gentlemen.
Everything being i❑ readiness the word was given, and
Miss Charlotte Prescott Laughton, daughter of the
Admiral Superintendent, having dashed a bottle of
champagne against the vessel's bows, at a few minutes
before twelve the ship glided majestically into her native
element, the bands playing appropriate airs, and the
spectators greeting her descent with loud and prolonged
cheering.
Some little time elapsed before the larger vessel was
got off, but the fineness-•of the day and the interesting
character of the scene effectually dispelled every feeling
of impatience among the crowd. Miss Ward, daughter
of the Secretary to the Admiralty, had the honour of
christening the Arrogant, an operation she performed,
by the way, very cleverly. The " dog-shores" having
at length been knocked away, the noble vessel left the
stocks and entered the water in magnificent style.
Not the slightest accident occurred, and the whole
affair passed off most satisfactorily.
The Arrogant was begu❑ in the month of September,
1845 ; the keel of the Plumper was laid in October last.
The employis in the dockyard had a half-holiday
granted them in celebration of the launch.

The ships will be taken into dock to-day, and cop-
pored, after which they will be jury-rigged, and navi-
gated to the Thames, to be fitted with their engines.
The draught of each vessel, with the bilgeways at-
tached, was as follows :—Arrogant, forwaad, 10 feet 6
inches; aft, 14 feet. Plumper, forward, 7 feet ; aft, 9
feet. Their symmetrical appearance on the water was
the subject of universal remark.
