LA. PLATA.

We have news ei<i New York from Monte Video,
of date 30th of June. There are also files of the
Cuonercio de fa Plato, from which the following are
extracts, us they elucidate the vexed questions of
that part of the world.
The news in question is contained in a long review
by the editor of the Conierciu of the state of affairs in
the South American republics, and is remarkable for
the very different vetsion it gives when compared
with the stories of the Buenos Ayrean papers.
The Cumercio states that by the last packet from
Europe, they had received news of the presentation
to the French Assembly of the treaty negotiated
last year with Roses and Oribo by Admiral Lo
Predour. After detailing some of the history
of the treaty, the Contereio goes on to say that
Franco has treated with Roses as the head of
the Argentine Republic, but in the interim, before
the treaty was ratified, Rosas had sent in his usual
resignation of his dictatorship over the provinces of
the Confederation; and two provinces of the Con-
federation, and the most important—Entre Rios and
Corrientes—had accepted the resignation, and their
governments had taken measures to manage their
own affairs until the general meeting of the Argen-
tine Congress, with the intention of forming a federal
compact. Roses has now no manner of authority,
nor any right to exercise authority, over these pro-
vinces. Consequently tho Le Predour treaty will
not be obligatory in the Argentine Confederation,
although it obtain the ratification of ltosas, if it
is not also accepted and ratified by the govern-
ments of Entre ltios and Corrientes ; and this,
at ys the Contereio, we are quite sure it will not be.
The Cumereio notices as a remarkable coincidence
that, on the first of May, the same day on which M.
Barochc presented to the French Assembly the treaty
concluded with Roses, the Governor of Entre Rios,
acknowledged the voluntary resignation of Governor
Rosas, and thus by this means deprived him of the
power of ratifying his own treaty ; and the day
before, the 30th of April, the Governor of Corrienits
was authorised by the legislature of the Province to
make tho same manifestation. The Comercio then
enumerates the following " successes," which the pro-
vinces have had during the month then closing:
Our government communicated to the Assembly of Nota-
bles the decision of the governor of Entre Rim, accepting '
the resignation of governor Rosas as chief of the Argentine
confederation, and resuming the independent sovereignty
of the province, to Wet with foreign powers until the
meeting of a general congress. The government of Cor-
rientes has transmitted similar despatches, and has taken
the same position, concurring with Entre Rios, to remove
with all the forces in its power these obstacles which mi_ght
impede the success of the new order of things. The
tovernment of Entre Rios has accredited in Monte Video

rorsarged'Affaires, and the first act of this officer has been ,
to offer to the Oriental government a hearty co-operation to
oppose the pretensions of Rosas and Oribe, and establish
firmly and securely the independence of the state, procure
a durable peace in the country, and establish
such an order of things as becomes a civilised and chris-
tian people, seeing that it is impossible to be prosper-
ous and powerful without peace and justice. Our
government has accepted this offer with the cordiality and
interest which this new and powerful alliance deserves, and
reciprocated all the offers which had been made, giving Ge-
neral Urquiza an assurance of a prompt and decided co-

mis-
sion to the government of Entre Rim, and sailed from
this port on the 16th inst. in the steamer Rio Lruguay,
bound to Conception, hs Uruguay, where he arrived on the
18th. On the lath he was received by Governor Unitas,
who came to the pueblo from his head-quarters for the pur-
pose of meeting the clear? trafaires. The Brazilian
squadron also entered the river, and formed a line stretch-
ing from the head of the colony to the mouth of the Gunn,
Admiral Grenfell having proceeded up the river to the port
of Conception in the steamer Recife, These movements
persuade us that the most perfect understanding exists be-
tween the Oriental and the Brazilian authorities and Gen.
Urguiza, and that the day is not distant when they will
make Roses feel the effects of their alliance.
Our letters from Uruguay advise us that the government
had received important advices from Paraguay, with the
President of which Republic we have enjoyed frendly rela-
tions and a good understanding. We are ip,nomnbof the
nature of the dispatches, but circumstances lead us to be-
lieve that the arrangements are entirely completed, fur
' the assistance of this powerful ally of Roses, in the impend-
' ing war.
