The Costa Rican Government lately framed an engagement with Colombia for settling by arbitration the boundary question between those countries, providing that the post of arbitrator should be offered successively to the King of the Belgians, the King of Spain, and the President of the Argentine Confederation.  The King of the Belgians has declined to act, but I am not as yet advised of the action of the King of Spain.  As we have certain interests in the disputed territory which are protected by our treaty engagements with one of the parties, it is important that the arbitration should not without our consent affect our rights, and this Government has accordingly thought proper to make its views known to the parties to the agreement, as well as to intimate them to the Belgian and Spanish Governments.

The questions growing out of the proposed interoceanic waterway across the Isthmus of Panama are of grave national importance.  This Government has not been unmindful of the solemn obligations imposed upon it by its compact of 1846 with Colombia, as the independent and sovereign mistress of the territory crossed by the canal, and has sought to render them effective by fresh engagements with the Colombian Republic looking to their practical execution.  The negotiations to this end, after they had reached what appeared to be a mutually satisfactory solution here, were met in Colombia by a disavowal of the powers which its envoy had assumed and by a proposal for renewed negotiation on a modified basis.

Meanwhile this Government learned that Colombia had proposed to the European powers to join in a guaranty of the neutrality of the proposed Panama canal—­a guaranty which would be in direct contravention of our obligation as the sole guarantor of the integrity of Colombian territory and of the neutrality of the canal itself.  My lamented predecessor felt it his duty to place before the European powers the reasons which make the prior guaranty of the United States indispensable, and for which the interjection of any foreign guaranty might be regarded as a superfluous and unfriendly act.

Foreseeing the probable reliance of the British Government on the provisions of the Clayton-Bulwer treaty of 1850 as affording room for a share in the guaranties which the United States covenanted with Colombia four years before, I have not hesitated to supplement the action of my predecessor by proposing to Her Majesty’s Government the modification of that instrument and the abrogation of such clauses thereof as do not comport with the obligations of the United States toward Colombia or with the vital needs of the two friendly parties to the compact.

This Government sees with great concern the continuance of the hostile relations between Chile, Bolivia, and Peru.  An early peace between these Republics is much to be desired, not only that they may themselves be spared further misery and bloodshed, but because their continued antagonism threatens consequences which are, in my judgment, dangerous to the interests of republican government on this continent and calculated to destroy the best elements of our free and peaceful civilization.
