Several of the governments regarding with favor the proposition of the United States have delayed definitive action upon it only for the purpose of consulting with others, parties to the conference of Paris. I have the satisfaction of stating, however, that the Emperor of Russia has entirely and explicitly approved of that modification and will cooperate in endeavoring to obtain the assent of other powers, and that assurances of a similar purport have been received in relation to the disposition of the Emperor of the French. The present aspect of this important subject allows us to cherish the hope that a principle so humane in its character, so just and equal in its operation, so essential to the prosperity of commercial nations, and so consonant to the sentiments of this enlightened period of the world will command the approbation of all maritime powers, and thus be incorporated into the code of international law.

My views on the subject are more fully set forth in the reply of the Secretary of State, a copy of which is herewith transmitted, to the communications on the subject made to this Government, especially to the communication of France.

The Government of the United States has at all times regarded with friendly interest the other States of America, formerly, like this country, European colonies, and now independent members of the great family of nations. But the unsettled condition of some of them, distracted by frequent revolutions, and thus incapable of regular and firm internal administration, has tended to embarrass occasionally our public intercourse by reason of wrongs which our citizens suffer at their hands, and which they are slow to redress.

Unfortunately, it is against the Republic of Mexico, with which it is our special desire to maintain a good understanding, that such complaints are most numerous; and although earnestly urged upon its attention, they have not as yet received the consideration which this Government had a right to expect. While reparation for past injuries has been withheld, others have been added. The political condition of that country, however, has been such as to demand forbearance on the part of the United States. I shall continue my efforts to procure for the wrongs of our citizens that redress which is indispensable to the continued friendly association of the two Republics.

The peculiar condition of affairs in Nicaragua in the early part of the present year rendered it important that this Government should have diplomatic relations with that State. Through its territory had been opened one of the principal thoroughfares across the isthmus connecting North and South America, on which a vast amount of property was transported and to which our citizens resorted in great numbers in passing between the Atlantic and Pacific coasts of the United States. The protection of both required that the existing power in that State should be regarded as a responsible Government, and its minister was accordingly received. But he remained here only a short time. Soon thereafter the political affairs of Nicaragua underwent unfavorable change and became involved in much uncertainty and confusion. Diplomatic representatives from two contending parties have been recently sent to this Government, but with the imperfect information possessed it was not possible to decide which was the Government de facto, and, awaiting further developments, I have refused to receive either.

Questions of the most serious nature are pending between the United States and the Republic of New Granada. The Government of that Republic undertook a year since to impose tonnage duties on foreign vessels in her ports, but the purpose was resisted by this Government as being contrary to existing treaty stipulations with the United States and to rights conferred by charter upon the Panama Railroad Company, and was accordingly refurbished at that time, it being admitted that our vessels were entitled to be exempt from tonnage duty in the free ports of Panama and Aspinwall. But the purpose has been recently revived on the part of New Granada by the enactment of a law to subject vessels visiting her ports to the tonnage duty of 40 cents per ton, and although the law has not been put in force, yet the right to enforce it is still asserted and may at any time be acted on by the Government of that Republic.

The Congress of New Granada has also enacted a law during the last year which levies a tax of more than $3 on every pound of mail matter transported across the Isthmus. The sum thus required to be paid on the mails of the United States would be nearly $2,000,000 annually in addition to the large sum payable by contract to the Panama Railroad Company. If the only objection to this exaction were the exorbitancy of its amount, it could not be submitted to by the United States.

The imposition of it, however, would obviously contravene our treaty with New Granada and infringe the contract of that Republic with the Panama Railroad Company. The law providing for this tax was by its terms to take effect on the 1st of September last, but the local authorities on the Isthmus have been induced to suspend its execution and to await further instructions on the subject from the Government of the Republic. I am not yet advised of the determination of that Government. If a measure so extraordinary in its character and so clearly contrary to treaty stipulations and the contract rights of the Panama Railroad Company, composed mostly of American citizens, should be persisted in, it will be the duty of the United States to resist its execution.

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.
