LATER FROM AMERICA.
Lxvtirroor:, MARCH 19.—8 y the arrival this
morning of the fine steamer America we are put in
possession of the following later news and dates:—
Boston; -March 6; Halifax, March 8 ; Cincinnati,
March 3 ; New Orleans, arch 2 ; New York and
Baltimore, March 5. She brings upwards of 100
passengers, and the usual American mails.
The discussion in the American Senate on the
slavery question had not terminated.
Mr. Calhoun addressed the Senate on the 4th in a
speech proposing the admission of California into the
Union, but admits therein, that if California is }e_.
ceivrd under its present constitution, the Union must
be dissolved.
By advices from California we learn that Sacra-
mento City is inundated. One million of dollars are
lost by the overflow.

Upwards of half a million dollars of specie further
have arrived from the mines.
There is nothing further new from Canada.
COMMERCIAL INTELLIGENCE.

NAVAL INTELLIGENCE.
THE EXPERIMENTAL SQUADRON.
Orr Llsnost. We have been out for the last ten
days trying rates of sailing, principally before the
wind. IVe have had nothing but light breezes, in
which the Leander certainly beats all.
We have had one trial on a wind, but it only lasted
an hour and a half, as it fell a calm.
The other day a towing match took place (Ter.
rible, Encounter, Arrogant, Hogue, &c.) Hogue
broke down at the commencement, but did extremely
well under half speed ; Terrible showed a great ad-
vantage over all the rest by at least doubling her
distance.
OFF GIBRALTAR, MARCH 7.—After receiving letters
off Lisbon, the squadron bore up for this place, and
will sail again to-morrow for a three weeks' cruise,
returning to Lisbon.
The Commodore says, this time he is going to put
the steamers to the test.
One of the officers of the Encounter is under arrest
on a most serious charge, which it is expected will
cause the ship to be sent home and a court-martial' to
be held.
It is expected the engines of the Hogue will soon
require the attention of the " home" department.
The Hogue and Indefatigable have been in eolli.
sion, by which the former lost her quarter-boat, and
had her spanker-boom carried away, and the latter her
spritsail-yard.
We understand the Commodore considerst the trials
off the wind to be conclusive, but those on the wind
are not so satisfactory. On that account some of the
work will have to be gone over again.
Orders have been given to complete water, and take
in four months' previsions of every kind, but this is
impossible. There is no bread in store, and but a
very limited supply of other necessaries. The people
complain sadly of the scarcity of water. The tanks
are very low, and the rock, which at this season is
generally very verdant, has yet a parched up ap-
pearance. Heavy showers, however, have fallen to-
day (Monday, the 4th inst.), which must prove highly
beneficial.
Tuesday—The Terrible has gone to lin -New
Mole, to coal. The Encounter goes to•morrow.—
Timt:_

PORTSMOUTH, MoNDAT.—The Dauntless,24, screw-
frigate, will be undocked on Wednesday, and fitted
fur trial immediately. She appears much improved
by the alteration sternways.
I'M Rolla, 8, Lieutenant Commander Fenwick,
will be docked when the Dauntless makes a vacancy,
to have her bottoms examined, &a. We are requested
to contradict a statement which appeared in a contem-
porary on Saturday, that the Rolla fouled a barque on
Friday, and did her damage. No such casualty has
taken place implicating the Rolla.
Areorsi-rmeriTs.
WooLwrcn, Maecn 18.—Srcond Master A. Stabb
(1847), to the Impregnable, 104, flagship at Devon-
port. Naval Cadet A. G. R. Roe, to the Impregnable
Henry L. Perceval, to the Fisgard, flagship at Wool-
wich.

Commander James A. St. Leger 0848), haying
finished his course of study at the steam factory at
Woolwich Dockyard, was examined by Mr. Trickett,
assistant to the chief engineer, and passed satis-
factorily.

Lieutenant Edward E. Maunsell (1846), having
completed his course of study of steam, was examined
to-day by Mr. Trickett and passed accordingly.
The last large balloon sent up by Mr. Shepherd
from the roof of the Admiralty, and whose course, so
far as known at the time, has been already given,
was ultimately found at Lewes, near Brighton, and
returned to the Admiralty. Mr. Shepherd has made
several balloons for Captain Collinson's expedition,
and they were forwarded on Saturday last to be sent
out with the West India mail, to reach the expedition
at the Sandwich Islands. A quantity of coloured
silks, with the necessary apparatus for printing the
dispatches, was sent at the same time.
PLTMOUTLY, MARCH 16.—Her Majesty's new
frigate Arethusa, 50, Captain Symonds' was on
Thursday towed by the Stromboli and Confiance
steamers from Hamoaaa into the Sound, where she
took her powder on board. The Stromboli went to
her moorings inside the breakwater ; the Confiance
returned up harbour. In the afternoon the Are-
' thusa went outside and made a trial cruise, the re-
sult of which was creditable to her sailing qualities.
Her crew will probably be paid on Tuesday, and
she will sail on Wednesday to join the squadron at
Lisbon.
The Archer steam-vessel was docked and had her
copper examined on Thursday-, and was undocked
yesterday.
Her Majesty's ship Albion, having been rigged for
commission, has been placed at her moorings in Ht..
tnoace ; her lower yards and topmasts are ordered to
be struck.
Her Majesty's ship Howe, 120, is ordered frona.the
Mediterranean to England, to be paid off. She may
be expected the latter end of March.
The Plymouth yacht has been removed from No. 2
dock and taken to the mast-house slip for more exten-
sive repair.
The Superb, 50, is ordered here from Queenstown,
to refit for foreign service.
Wind easterly.
MARCH 17.—A Government transport, from the
eastward, entered the Sound this morning, and an-
chored inside the breakwater.
