Mr. Hall to Mr. Bayard.

No. 699.]

Sir: With my dispatch No. 696, of the 11th instant, I had the honor to transmit an abstract of the last boundary treaty between Nicaragua and Costa Rica, signed at this place on the 26th ultimo. I now inclose a translation of the treaty itself.

The Congress of Costa Rica is now in session, and will no doubt ratify the treaty. An extra session of the Nicaraguan Congress has been called for the same object, to meet on the 1st proximo. I understand that the treaty meets with opposition, but the general belief is that it will be ratified.

I have, etc.,

Henry C. Hall.
[Inclosure.]

Convention of the 26th July, 1887, between Nicaragua and Costa Rica.

The Presidents of Nicaragua and Costa Rica, desiring to terminate all questions pending between the two Republics, after having conferred together in presence of their respective ministers for foreign affairs, have agreed to the following articles:

Article 1.

The Government of Nicaragua withdraws its objections touching the validity of the boundary treaty with Costa Rica of the 15th April, 1858, and on its part will obtain a second ratification thereof from the Nicaraguan Congress, which it maintains is indispensable.

Article 2.

With the object of making the river San Juan navigable at all seasons, the Government of Costa Rica consents to the diversion of the waters of the Colorado into the San Juan as far as may be necessary, and to the construction of the works required to effect such diversion.

Article 3.

The Government of Costa Rica will contribute one-fourth part of the cost of the improvement of the San Juan River between the Colorado and the Bay of San Juan del Norte. When the works shall commence the contracting Governments shall appoint a professional commission to determine what may be essential and to make an estimate of the cost. When the amount estimated shall have been ascertained the contracting Governments shall agree as to the appropriation of the funds and the disbursements thereof.

Article 4.

Nicaragua concedes to Costa Rica in perpetuity for commercial purposes the right of free navigation in Lake Nicaragua and in that part of the San Juan River from which she is now excluded. Notwithstanding, the special privilege granted to F. A. Pellas on the 16th March, 1877, for navigating those waters by steamers, shall be respected.

Article 5.

Costa Rica has the right to participate in the profits of the interoceanic canal that may be constructed on the line of the San Juan River, but, in regard to the share of such profits which Costa Rica shall receive, the contracting Governments shall submit the matter to the decision of an arbitrator, who shall decide in view of the route definitely adopted, and taking into consideration, on the one hand, the lands and wafers which Costa Rica gives to the enterprise, and, on the other hand, the lands, waters, and rights which Nicaragua contributes.

When the route of the canal shall have been definitely adopted the two Governments, at the instance of either, shall come to an agreement for the appointment of an arbitrator, and the conditions and proceedings to be observed during the arbitration.

Costa Rica accepts, on her part and in all that relates to her rights, the concession made by Nicaragua to the “Nicaragua Canal Company,” by contract of the 23d of March, 1887.

Article 6.

The points of doubtful interpretation in the treaty of 1858 thus far presented are decided as follows:

(1)
The “Punta de Castilla” shall at present be taken to be the extremity of the right bank of the mouth of the San Juan River nearest to the port of San Juan del Norte. When the improvement referred to in Article 2 shall have been carried out “Punta de Castilla” shall be understood to be the extremity of the right bank of the San Juan River as the improvement leaves it.
(2)
The central point of the bay of Salinas shall be fixed by the intersection of its two axes, major arid minor.
(3.)
The right conceded to Costa Rica to navigate the San Juan River from its mouth to 3 miles below Castillo Viejo, for commercial purposes, does not include the right of navigation by vessels of war and revenue exercising jurisdiction.

Article 7.

Nicaragua may freely grant concessions for a canal or transit route when such concessions do not prejudice the rights of Costa Rica, without awaiting the consultative vote referred to in Article 8 of the treaty of 1858, which consultative vote Costa Rica hereby renounces.

Article 8.

The revenue vessels of Costa Rica conveying customs guards to any point of the right bank of the San Juan River within Costa Rican territory, or to Rio Frio, or conveying supplies to the customs guards there established, may pass through Nicaraguan waters as long as they do not exercise therein any act of jurisdiction.

Article 9.

In order to make the necessary measurements to fix the boundary line and to establish appropriate landmarks, the two Governments shall, within six months from the exchange of the ratifications of this treaty, appoint their respective commissions in such form as they shall agree upon. The measurements and the landmarks shall be concluded within ten years, counting from the appointment of the commission.

Article 10.

This treaty shall be submitted to the approbation of the Congresses of both Republics, and the ratifications thereof exchanged in San José, Costa Rica, or in Managua, within one hundred and twenty days from the date hereof, or earlier if possible.

Until this treaty shall have been so ratified the arbitration convention between the two Republics, signed at Guatemala the 24th December, 1886, shall remain in force and vigor.
