UNITED STATES.

As announced in oar yesterday's impremloo, the
Royal Mail Steam-ship America arrived in the
Money about 8 a.m. of this day. She sailed from
Boston on the Ist inst., and from Halifax on the 3rd.
Some apprehensions had bees entertained for the
Cambria, *Mph had not been beard of at New York
when the mail was despatched. As will be seen,
however, by the electric telegraph despatch to Hali-
fax, the news of her arrival bad been received there,
and had caused an advance in the price of cotton.
The political news by the America is of little mo-
ment. The pro-slavery pipers announce that the
cotton manufacture in New England is suffering—
that " three of the Leger* cotton mills at Lowell are
discharging the operatives and intend to stop making
cloth—the Lawrence, the Tremont, and the Suffolk."
The reason assigned for this step is said to be the
high price of the cotton and the low price of
the cloth. And the high price of the cotton is
attributed to—the frost in April, 1839 ; the number of
cotton planters who have transferred their capital and
enterprise to railroad and other speculations; and the
number who have emigrated to California. With
angular inconsistence the sameiournals which parade
these reasons, declare that nothing can save the cotton
planting and cotton manufacture of the United States
but the surcease of the anti-slavery agitation in the
mouth. We suspect that the distress of the Lowell
manufacturers is like the distress of the agricultural
and colonial interests here, a temporary pressure ex-
aggerated in order to create a prejudice against an
intuitable reform. The stoppirg of the mills is used
there to get op a cry against negro emancipation, just
as low prices in oorn are used here as en argument
for re-enacting the corn law.
Mr. Webster visited Boston on the 29th ult., and
experienced a most enthusiastic reception. From the
tenor of a speech which he delivered from his car-
riage we feel disposed to infer that Mr. Webster had
found it expedient, if not necessary, to visit New
England, to endeavour to reconcile his constituents
to the compromise on the slavery question men-
tioned in the settlement of the Californian con-
t roversy.
From Boston we learn that the counsel of Pro-
fessor Webster have taken out • writ of error, upon
the ground that the order of the Municipal Court for
certifying the indictment up to the Supreme Court
was not truly set forth by the clerk of the former
court

THE AMERICAN PRESS ON THE EXHIBITION

The Boston Ail2S. of 29th April, says of the exhibition.—
.. The conditions are worthy of the stately pride of Great
Britain. The Earl of Carlisle, the first speaker at tha meet-
ing referred to, said that Greet Britain invites all the
nations of the earth to the competition ; but, though she
invites them and their representatives to compete, she dots
not ask them to contribute to the preliminaries. The com-
petition is to be international, the preparation en 4 arrange-
meats to be wholly national.' The Earl of Carlisle (who,
as Lord limpet's, visited our country some years ago) took
occasion, at the meeting of Feb. 21, kindly to give us of the
United States especial invitation, and tell hie countrymen,
I own to you that I do not anticipate advantages to
Great Britain from our victories alone, but fromour defeats.'
We hope that the contributors to our Washington, New
York, B,ston, and other fairs, will do their best to favor the
earl, and the workingmen of Great Britain, with that last
I mentioned advantage."
