US Presidency
1851

It was stated in the last annual report of the Secretary of the Interior that the initial point on the Pacific and the point of junction of the Gila with the Colorado River had been determined and the intervening line, about 150 miles in length, run and marked by temporary monuments. Since that time a monument of marble has been erected at the initial point, and permanent landmarks of iron have been placed at suitable distances along the line. The initial point on the Rio Grande has also been fixed by the commissioners, at latitude 32 degrees 22 ', and at the date of the last communication the survey of the line had been made thence westward about 150 miles to the neighborhood of the copper mines. The commission on our part was at first organized on a scale which experience proved to be unwieldy and attended with unnecessary expense.
