THE BOUNDARY SURVEY BETWEEN MEXICO AND THE UNITED STATES. – The Department of the Interior is now engaged in dispatching the party to make this survey. It is expected that they will reach Indianola, Texas, about the 15th of October, and leave San Antonio about the first week in November for the Rio Grande, near El Paso. When they arrive at the latter point they will at once begin operations on the 32d parallel. This will allow an earlier start at the work than has heretofore been expected, but in order to facilitate their operations, and save expense, the department has determined to reverse the order of the survey, and commence at the point where it is contemplated by the law (the act of June 8, 1858) that the labors of the expedition shall terminate. – Washington Star.
