of my predecessor to the House of Representatives
of the 8th of February last, communicating, in compliance with a
resolution of that body, 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 plenipotentiary of that
Republic accredited to this Government, a transcript of that
correspondence is herewith submitted.

The commissioner on the part 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 progress
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 fund 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 supplies except at or near
the extremes of the line render it also indispensable that a liberal
provision should be made to meet the necessary charges during the fiscal
year ending on the 30th of June, 1851. I accordingly recommend this
subject to your attention.

In the adjustment of the claims of American citizens on Mexico, provided
for by the late treaty, the employment of counsel on the part of the
Government may become important for the purpose of assisting the
commissioners in protecting the interests of the United States. I
recommend this subject to the early and favorable consideration of
Congress.

Complaints have been made in regard to the inefficiency of the means
provided by the Government of New Granada for transporting the United
States mail across the Isthmus of Panama, pursuant to our postal
convention with that Republic of the 6th of March, 1844. Our charge
d'affaires at Bogota has been directed to make such representations to
the Government of New Granada as will, it is hoped, lea
