MEXICO.

With the republic of Mexico it is our true policy
to cultivate the most friendly relations. Since the
ratification of the treaty of Guadeloupe Hidalgo,
nothing has occurred of a serious character to disturb
them. A faithful observance of the treaty, and a
sincere respect for her rights, cannot fail to secure the
lasting confidence and friendship of that republic.
The Message of my predecessor to the House of
Representatives, of the Bth of February last, commu-
nicating, in compliance with a resolution of that bady,
a copy of a paper called a protocol, signed at Queretaro
on the 30th of May, 1848, by the Commissioners of
the United States and the Minister of Foreign Affairs
of the Mexican Government, having been a subject of
correspondence between the Department of State and
the Envoy Extraordinary and Minister Plenipoten-
tiary of that republic accredited to this Government,
a transcript of that correspondence is herewith sub-
mitted.

The Commissioner on the Flirt of the United States
for marking the boundary between the two republics,
though delayed in reaching San Diego by unforeseen
obstacles, arrived at that place within a short period
after the time required by the treaty, and was there
joined by the Commissioner on the part of Mexico.
They entered upon their duties ; and, at the date of
the latest intelligence from that quarter, some pro-
gress had been made in the survey. The expenses
incident to the organization of the commission, and to
its conveyance to the point where its operations were
to begin, have so much reduced the hind appropriated
by Congress, that a further sum, to cover the charges
which must be incurred during the present fiscal
year, will be necessary. The great length of frontier
along which the boundary extends, the nature of the
adjacent territory, and the difficulty of obtaining sup-
plies, except at or near the extremes of the line,
render it almost indispensable that a liberal provision
should be made to meet the necessary charges during
the fiscal year ending on the 30th of June, 1851. 1
accordingly recommend this subject to:your attention.
In the adjustment of the claims of American citi-
zens on Mexico, provided for by the late treaty, the
employment of counsel, on the part of the Govern-
ment, may become important for the purpose of
assisting the Commissioners in protecting the in-
terests of the United States. I recommend this sub-
ject to the early and favourable consideration of
Congress.

THE ISTHMUS.
Complaints have been made in regard to the ineffi-
ciency of the means provided by the Government of
New Grenada for transporting the United States
mail across the Isthmus of Panama, pursuant to our
postal convention with that Republic, of the 6th of
4d'Affaires at Bogota has

resentations to the
Government of New Grenada as will, it is hoped,
lead to a prompt removal of this cause of complaint.
THE SOUTEI-ABIERICAN STATES.
of Venezuela has for some time past been ravaged
h
Civil War with which the Republic
brought to a close. In its progress, the
riagsTh bhts:en sanguinaryof some of our citizens resident or trading
there had been violated. The restoration of order
will afford the Venezuelan Government an opportunity
to examine and redress these grievances and others of
long standing, which our representatives at Caraccas
have hitherto in effectually urged upon the attention
of that Government.

The extension of the coast of the United States on
the Pacific, and the unexampled rapidity with which
the inhabitants of California, especially, are increas-
ing in numbers, have imparted new consequence to
our relations with the other countries whose
territo-
ries border upon the ocean. It is probable that the R
intercourse between those countries and our posses-
sions in that quarter, particularly with the epublic
of Chili, will become extensive and mutually advan-
tageous in proportion as California and Oregon shall
increase in population and wealth. It is desirable,
therefore, that this Government should do everything
in its power to foster and strengthen its relations
with those states, and that the spirit of amity between
us should be mutual and cordial.
I recommend the observance of the same course
towards all other American States. The United
States stand as the great American Power to which,
as their natural ally and friend, they will always be
disposed, first, to look for mediation and assistance,
in the event of any collision between them and any
European nation. As such,
we may often kindly
mediate in their behalf, without entangling ourselves
in foreign wars or unnecessary controvenies. When-
ever the faith of our treaties with any of them shall
require our interference we must necessarily in-
terpose.
