From Mexico

By steamer Massachusetts that arrived at New Orleans the 20th, ultimo, brings the following news Mr. Trist still remains in Mexico; his health has been entirely restored. A mail will run twice a month between mexico and Vera Cruz, leaving Mexico on the first and fifteenth of each month. The Mexican papers comment with great severity on Santa Anna's letter on his military course. The Archbishop of Mexico has written a long protest against the heavy assessments of church property. Generals Worth and Pillow have been restored to their command, the first to his original, the second not known. The Mexican Congress, says the N. American, is nowhere. Sometimes a dozen delegates -- never a quorum. An intelligent gentleman residing at Mexico, gives the probable action of the Mexican Congress on the treaty. He dates March 3, in which he says there are not at this time thirty members of Congress; so you see there is but little prospect of there being a ratification within the term agreed upon in the treaty.
