I regret exceedingly that occasion exists to invite your attention to a subject of still graver import in our relations with the Republic of New Granada.  On the 15th day of April last a riotous assemblage of the inhabitants of Panama committed a violent and outrageous attack on the premises of the railroad company and the passengers and other persons in or near the same, involving the death of several citizens of the United States, the pillage of many others, and the destruction of a large amount of property belonging to the railroad company.  I caused full investigation of that event to be made, and the result shows satisfactorily that complete responsibility for what occurred attaches to the Government of New Granada.  I have therefore demanded of that Government that the perpetrators of the wrongs in question should be punished; that provision should be made for the families of citizens of the United States who were killed, with full indemnity for the property pillaged or destroyed.

The present condition of the Isthmus of Panama, in so far as regards the security of persons and property passing over it, requires serious consideration.  Recent incidents tend to show that the local authorities can not be relied on to maintain the public peace of Panama, and there is just ground for apprehension that a portion of the inhabitants are meditating further outrages, without adequate measures for the security and protection of persons or property having been taken, either by the State of Panama or by the General Government of New Granada.

Under the guaranties of treaty, citizens of the United States have, by the outlay of several million dollars, constructed a railroad across the Isthmus, and it has become the main route between our Atlantic and Pacific possessions, over which multitudes of our citizens and a vast amount of property are constantly passing; to the security and protection of all which and the continuance of the public advantages involved it is impossible for the Government of the United States to be indifferent.

I have deemed the danger of the recurrence of scenes of lawless violence in this quarter so imminent as to make it my duty to station a part of our naval force in the harbors of Panama and Aspinwall, in order to protect the persons and property of the citizens of the United States in those ports and to insure to them safe passage across the Isthmus.  And it would, in my judgment, be unwise to withdraw the naval force now in those ports until, by the spontaneous action of the Republic of New Granada or otherwise, some adequate arrangement shall have been made for the protection and security of a line of interoceanic communication, so important at this time not to the United States only, but to all other maritime states, both of Europe and America.

Meanwhile negotiations have been instituted, by means of a special commission, to obtain from New Granada full indemnity for injuries sustained by our citizens on the Isthmus and satisfactory security for the general interests of the United States.
