Mr. Calvo to Mr. Olney.

Sir: In a communication dated May 11 of the past year, 1896, I had the honor to inform your excellency of there having been signed on March 27 of that year, at the capital of Salvador, with the honorable and fraternal mediation of His Excellency the President of that State, a convention for the survey and marking of the divisional line between Costa Rica and Nicaragua, pursuant to the provisions of the boundary treaty of April 15, 1858, and the arbitral award made on March 22, 1888, by His Excellency Grover Cleveland, President of the United States of America, and to bring to the high knowledge of your excellency that, pursuant to one of the stipulations of that convention, the two contracting Governments would proceed, jointly, in due time to request His Excellency the President of the United States of America to consent to name an engineer who, completing the respective commissions of the two countries, and with ample authority conferred upon him by the convention, shall decide any kind of difficulties that may arise in the operation mentioned of establishing the divisional line in accordance with the said treaty and award.

I now have the honor to communicate to your excellency that the convention of Salvador has been ratified by both parties and that the ratifications were duly exchanged in San José de Costa Rica on the 17th of December last, as is evidenced by the certified copy and translation of the said document hereto annexed.

Your excellency was pleased, in a note dated May 5 last, addressed to this legation, to express the favorable disposition of His Excellency the President of the Republic, to the effect that he would grant the request mentioned.

In this understanding, complying with the stipulations of the convention to which I have referred, in the name of the Government of the Republic of Costa Rica, on its part, and through the honorable medium of your excellency, I now formally request His Excellency the President of the United States of America to be pleased to accede to the wishes of the two Governments, as they have been solemnly expressed in the said convention, thus again meriting their gratitude.

With assurances, etc.,

J. B. Calvo.
