WASHINGTON, _July 20, 1850_.
_To the Senate of the United States_:
I herewith transmit to the Senate, with a view to its ratification, a
convention between the United States and the Mexican Republic for the
extradition of fugitives from justice. This convention was negotiated
under the directions of my predecessor, and was signed this day by
John M. Clayton, Secretary of State, on the part of the United States,
and by Senor Don Luis de la Rosa, envoy extraordinary and minister
plenipotentiary of Mexico, on the part of that Republic. The length of
the boundary line between the two countries, extending, as it does,
from the Pacific to the Gulf, renders such a convention indispensable
to the maintenance of good order and the amicable relations now so
happily subsisting between the sister Republics.
