WASHINGTON, _February 25, 1851_.
_To the Senate of the United States_:
I transmit to the Senate, for its consideration with a view to
ratification, a convention between the United States and the Mexican
Republic for the protection of a transit way across the Isthmus of
Tehuantepec, signed in the City of Mexico on the 25th ultimo.
Accompanying the treaty is a letter from Mr. P.A. Hargous, the present
proprietor and holder of the privileges granted by Mexico, signifying
his assent to and acceptance of the terms of its provisions. There is
also an abstract of title to him from the original grantee and copies
of the several powers and conveyances by which that title is derived to
him. It may be well that these papers should be returned to be deposited
among the archives of the Department of State.
The additional article of the treaty makes an unnecessary reference to
the eleventh, twelfth, and thirteenth articles of the treaty of the 22d
of June last, because the eleventh, twelfth, and thirteenth articles
of the present treaty contain exactly the same provisions as those
contained in the same articles of that treaty, as will appear from the
copy of the treaty of the 22d of June last, herewith communicated.
