You will present these views to the minister of foreign relations of Mexico, enlarging, if need be, in such terms as will readily occur to you, upon the great mission which it is within the power of the proposed congress to accomplish in the interest of humanity, and upon the firm purpose of the United States to maintain a position of the most absolute and impartial friendship toward all. You will thereupon, in the name of the President of the United States, tender to His Excellency the President of the Mexican Republic a formal invitation to send two commissioners to the congress, provided with such powers and instructions on behalf of their Government as will enable them to consider the questions brought before that body within the limit of submission contemplated by this invitation.
The United States as well as the other powers will in like manner be represented by two commissioners, so that equality and impartiality will be amply secured in the proceedings of the congress.
In delivering this invitation through the minister of foreign affairs you will read this dispatch to him and leave with him a copy, intimating that an answer is desired by this Government as promptly as the just consideration of so important a proposition will permit.
I am, sir, your obedient servant,
JAMES G. BLAINE.
EXECUTIVE MANSION, April 18, 1882.
To the Senate and House of Representatives:
I transmit herewith, for the consideration of Congress, a note addressed by the minister plenipotentiary of Mexico to the Secretary of State, proposing the conclusion of a convention between the two countries for defining the boundary between the United States and Mexico from the Rio Grande westward to the Pacific Ocean by the erection of durable monuments. I also lay before Congress a letter on the same subject, with its accompaniment, from the Secretary of War, to whom the proposition was referred by the Secretary of State for the expression of his views thereon.
I deem it important that the boundary line between the two countries, as defined by existing treaties and already once surveyed, should be run anew and defined by suitable permanent monuments. By so doing uncertainty will be prevented as to jurisdiction in criminal and municipal affairs, and questions be averted which may at any time in the near future arise with the growth of population on the border.
Moreover, I conceive that the willing and speedy assent of the Government of the United States to the proposal thus to determine the existing stipulated boundary with permanence and precision will be in some sense an assurance to Mexico that the unauthorized suspicion which of late years seems to have gained some credence in that Republic that the United States covets and seeks to annex neighboring territory is without foundation. That which the United States seeks, and which the definite settlement of the boundary in the proposed manner will promote, is a confiding and friendly feeling between the two nations, leading to advantageous commerce and closer commercial relations.
