_To the Senate of the United States_:
I lay before the Senate a letter of the 12th February, 1848, from N.P.
Trist, together with the authenticated map of the United Mexican States
and of the plan of the port of San Diego, referred to in the fifth

between the United States of America and the Mexican Republic," which
treaty was transmitted to the Senate with my message of the 22d ultimo.
