inestimable privilege. The true interpretation of the obligations upon which the United States entered in this treaty of 1846 has been given repeatedly in the utterances of Presidents and Secretaries of State. Secretary Cuss in 1858 officially stated the position of this Government as follows: "The progress of events has rendered the interoceanic route across the narrow portion of Central America vastly important to the commercial world, and especially to the United States, whose possessions extend along the Atlantic and Pacific coasts, and demand the speediest and easiest modes of communication. While the rights of sovereignty of the states occupying this region should always be respected, we shall expect that these rights be exercised in a spirit befitting the occasion and the wants and circumstances that have arisen. Sovereignty has its duties as well as its rights, and none of these local governments, even if administered with more regard to the just demands of other nations than they have been, would be permitted, in a spirit of Eastern isolation, to close the gates of intercourse on the great highways of the world, and justify the act by the pretension that these avenues of trade and travel belong to them and that they choose to shut them, or, what is almost equivalent, to encumber them with such unjust relations as would prevent their general use." Seven years later, in 1865, Mr. Seward in different communications took the following position: "The United States have taken and will take no interest in any question of internal revolution in the State of Panama, or any State of the United States of Colombia, but will maintain a perfect neutrality in connection with such domestic altercations. The United States will, nevertheless, hold themselves ready to protect the transit trade across the Isthmus against invasion of either domestic or foreign disturbers of the peace of the State of Panama. Neither the text nor the spirit of the stipulation in that article by which the United States engages to preserve the neutrality of the Isthmus of Panama, imposes an obligation on this Government to comply with the requisition of the President of the United States of Colombia for a force to protect the Isthmus of Panama from a body of insurgents of that country. The purpose of the stipulation was to guarantee the Isthmus against seizure or invasion by a foreign power only." Attorney-General Speed, under date of November 7, 1865, advised Secretary Seward as follows: "From this treaty it can not be supposed that New Granada invited the United States to become a party to the intestine troubles of that Government, nor did the United States become bound to take sides in the domestic broils of New Granada. The United States did guarantee New Granada in the sovereignty and property over the territory. This was as against other and foreign governments."
