Emergencies growing out of civil war in the United States of Colombia demanded of the Government at the beginning of this Administration the employment of armed forces to fulfill its guaranties under the thirty-fifth article of the treaty of 1846, in order to keep the transit open across the Isthmus of Panama. Desirous of exercising only the powers expressly reserved to us by the treaty, and mindful of the rights of Colombia, the forces sent to the Isthmus were instructed to confine their action to "positively and efficaciously" preventing the transit and its accessories from being "interrupted or embarrassed." The execution of this delicate and responsible task necessarily involved police control where the local authority was temporarily powerless, but always in aid of the sovereignty of Colombia. The prompt and successful fulfillment of its duty by this Government was highly appreciated by the Government of Colombia, and has been followed by expressions of its satisfaction. High praise is due to the officers and men engaged in this service. The restoration of peace on the Isthmus by the reestablishment of the constituted Government there being thus accomplished, the forces of the United States were withdrawn. Pending these occurrences a question of much importance was presented by decrees of the Colombian Government proclaiming the closure of certain ports then in the hands of insurgents and declaring vessels held by the revolutionists to be piratical and liable to capture by any power. To neither of these propositions could the United States assent. An effective closure of ports not in the possession of the Government, but held by hostile partisans, could not be recognized; neither could the vessels of insurgents against the legitimate sovereignty be deemed hostes humani generis within the precepts of international law, whatever might be the definition and penalty of their acts under the municipal law of the State against whose authority they were in revolt. The denial by this Government of the Colombian propositions did not, however, imply the admission of a belligerent status on the part of the insurgents. The Colombian Government has expressed its willingness to negotiate conventions for the adjustment by arbitration of claims by foreign citizens arising out of the destruction of the city of Aspinwall by the insurrectionary forces. The interest of the United States in a practicable transit for ships across the strip of land separating the Atlantic from the Pacific has been repeatedly manifested during the last half century. My immediate predecessor caused to be negotiated with Nicaragua a treaty for the construction, by and at the sole cost of the United States, of a canal through Nicaraguan territory, and laid it before the Senate. Pending the action of that body thereon, I withdrew the treaty for reexamination. Attentive consideration of its provisions leads me to withhold it from resubmission to the Senate.
