AMERICAN NEWS.

LIVERPOOL, SUNDAY MORNING.
The British mail steam-ship Niagara, Captain Stdne,
arrived here this morning at half-past five o'clock,
having left Boston on the 14th and Halifax on the
16th, with the mails and 87 passengers.
The American mail steam-ship Arctic, which left
Liverpool on the 30th ult., reached New York on
the 11th.

The British mail steam-ship Canibria, hence on the
3d inst., arrived out at Halifax on the 13th, landed
her mails and passengers, and left again for Boston.
The United States mail steamer Georgia, Captain
Schenck, sailed for Havaneah and New Orleans.
By this arrilal we have three days' later intelli-
gence than previously received by the Pacific on Tues-
day last.
The projected invasion of Cuba excitement seems
to have greatly subsided.
On Sunday night, the 27th ult., the Welaka left
Savannah with the United States marshal and others
on board for the south. She returned early on
Thursday knorning, bringing the following informa-
tion from the various points at which she stopped
during her trip.
At St. Mary a there were rumours that bodies of
men had passed through the interior, destined south,
and that in the vicinity of Jacksonville, Florida, they
were encamped in considerable force.

At Jacksonville similar rumours of armed men
being encamped at different points on the coast ex-
isted, but from reliable information, obtained from
respectable sources, it was ascertained that at the pre-
sent time there is no organization of men in the im-
mediate neighbourhood, and had not been. At that
place there are but few persons who do not sympa-
thise with and would aid the expedition as far as
possible.
On the arrival of the Welaka at deffersontore it was
ascertained that there were no bodies of men en-
camped, as reported, at Burnet Fort. Some small
parties, it was said, had passed this point, but their
destination was not ascertained, and but little reliance
could be placed on the rumours. A gentleman, on
whose word every reliance could be placed, stated
that the day before be bad passed an abandoned en-
campment some 20 miles above, where a large body of
men had but a short time before been encamped.
At Darien no particular information was obtained.
A body of men connected with the expedition had
come down from the interior and gone south.
From all that was gathered it was not the inten-
tion of the leaders to actually organize the expedition
in the States, but to sail unorganized to some point
beyond the United States, and there make such ar-
rangements as should be deemed expedient.
The South Carolina States Rights Convention ad-
journed on the Bth instant after a session of three
days. On the assembling of the convention a letter
from Langdon Cheves was read, deprecating separate
state action, and recommending forbearance and con-
ciliation. A committee of 21 was appointed to pre-
pare resolutions and an address, which after consider-
able discussion were adopted. Their purport is :
That in the opinion of the convention secession with
or without the co-operation of other states is neces-
sary; that concert of action with other states is
worth many sacrifices, but not that of submission;
that the right of secession is essential to the sove-
reignty of the states ; and lastly, that the meeting
looks to the convention of the people and to the Legis-
lature to exert the sovereign power of the state in
defence of its rights. Mr. Barnwell and two other
members of the committee presented a minority re-
port, referring the whole matter to the action of the
Legislature. Judge Butler, United States senator,
also recommended a postponement of any decisive
step. The original report, however, was adopted, and,
the convention adjourned sine die.
A good deal of excitement was produced in New
York on Saturday, by the announcement that the
United States Government had chartered a steamer
to leave New York with a force of 700 men. It was
not known whether this vessel•was destined to sup-
press rebellion in South Carolina or to prevent the
invasion of Cuba, although rumour spoke confidently
of both purposes. According to the best information
which we have yet obtained, it seems that this vessel
has been chartered at the suggestion of the United
States authorities in New York, to cruise along the
coast between this port and Savannah. One of the
Chagres steamers, the Crescent City, is the vessel
engaged for the service, and she will probably go to
sea without delay.
Colonel Sumner, who is about to take command
of the United States military force in the department
of Santa Fe, will take out with bins several hundred
fresh recruits to fill up the companies now in New
Mexico.

The Exchange at Santa Fe, the finest bar-room in
the country, with all its outhouses, &c., has been
burned to the ground. __ _

A meeting has been held at Yorktown, Va., at
which Daniel Webster was nominated as candidate
for the presidency in 1852. _ _ _

A new and interesting experiment has been tried
with Professor Page's electromagnetic locomotive,
on the railroad between Washington and Bladens-
burg!). The distance was accomplished in 39 mi-
nutes, the greatest speed being 19 miles an hour, and
about 7 more than any previous experiment. Several
difficulties occurred on account of the derangements
of parts of the machinery, but on the whole tile result
of the experiment was considered highly satisfactory.
Jenny Lind reached New York a week ago, after
her triumphant five months' tour in the south and
west.

A New York paper says—
" The President of the United States. with all his Ca-
binet Ministers, except Mr. Corwin, who is unfortunately
detained by ill health, will arrive here to-day, in order
to participate in the celebration which attends the open-
ing of the Erie Railroad. Their visit is induced by the
completion of one of the most important material enter-
prises ever undertaken. To the commercial metropolis,
to the state, to the west, to the whole country, this
event marks an era cf greater and more substantial
prosperity, and it is fitting that it should be welcomed
by public festivities, and that the chief magistrate and
his constitutional advisers should honour it by their pre-
sence."

CENTRAL AMERICA.
Our latest advices from Nicaragua state that the
British naval forces at San Juan had been entirely
withdrawn, and the English were about to abandon
the Mosquito protectorate, and surrender the port of
San Juan, and the whole of the territory claimed as
Mosquito, to the Nicaraguan Government.

LATER FROM BUENOS AYRES, &c.
BOSTON, Max 12.—The ship Dragon, from Buenos
Ayres, March 21, Monte Video, 23d, arrived at this
port this morning. The packet says that at her de-
parture every mark of cordiality and respect was
shown. The drought and locusts have been commit-
ting fell havoc in some parts of the country, destroy-
ing the crop of wheat, which is very defective both in
quantity and quality. The reports remain closed
against foreign grain, but should the threatened
scarcity prove real, no doubt the restrictions will be
removed. Political news is unimportant. The im-
prisonment
of General Riverro, at Rio Janeiro, was
looked upon as a pacific indication, bad not the re-
newed treaty of Brazil with the provincial Govern-
ment of Paraguay come to a neutralization of its
effect. The ulterior movements of the Brazilian
Cabinet are likely to be effected, if not decided, by
the fate of the Le Predour Convention in the French
Assembly.
