oextensive with the Empire, fugitives from justice found in any of
these States would be surrendered up on the requisition of our minister
at Frankfort. This would be more convenient and effectual than to
address such separate requisitions to each of the nineteen German States
with which the convention was concluded.

I communicate herewith, for the information of the Senate, copies of a
dispatch from our minister at Berlin and a communication from our consul
at Darmstadt.

WASHINGTON, _July 29, 1848_.

_To the House of Representatives of the United States_:

In answer to the resolution of the House of Representatives of the 17th
instant, requesting the President "to communicate, if not inconsistent
with the public interests, copies of all instructions given to the Hon.
Ambrose H. Sevier and Nathan Clifford, commissioners appointed to
conduct negotiations for the ratification of the treaty lately concluded
between the United States and the Republic of Mexico," I have to state
that in my opinion it would be "inconsistent with the public interests"
to give publicity to these instructions at the present time.

I avail myself of this occasion to observe that, as a general rule
applicable to all our important negotiations with foreign powers, it
could not fail to be prejudicial to the public interest to publish the
instructions to our ministers until some time had elapsed after the
conclusion of such negotiations.

In the present case the object of the mission of our commissioners to
Mexico has been accomplished. The treaty, as amended by the Senate of
the United States, has been ratified. The ratifications have been
exchanged and the treaty has been proclaimed as the supreme law of the
land. No contingency occurred which made it either necessary or proper
for our commissioners to enter upon any negotiations with the Mexican
Government further than to urge upon that Government the ratification of
the treaty in its amended form.

_To the Senate of the United States_:

I communicate herewith a report from the Secretary of State, containing
the information called for by the resolution of the Senate of the 24th
of April, 1848, in relation "to the claim of the owners of the ship
_Miles_, of Warren, in the State of Rhode Island, upon the Government of
Portugal for the payment of a cargo of oil taken by the officers and
applied to the uses of that Go
