Mr. Dayton to Mr. Seward.

No. 185.]

Sir: I have to-day called the attention of Mr. Thouvenel to your despatch No. 180, in reference to the application of New Granada for assistance in the preservation of the neutrality of the Isthmus and the sovereignty of that country. Somewhat to my surprise, I found that your despatch had not been submitted by the minister ad interim to Mr. Thouvenel on his return, and that, in point of fact, he had not yet seen it. He informed me, however, that the same question, substantially, had been presented to him through Mr. Mercier, and that a written reply had been forwarded, some days since, which doubtless has been, or will be, promptly communicated to you. Mr. Thouvenel, however, seemed to think your communication was rather in the nature of a conference as to what you should, under the circumstances, do, than as indicating any fixed determination to act in the premises. He says that, in the view he took, he did not see that it was necessary that you should, under the treaty, do anything at all. That the neutrality of the Isthmus was not question and the railroad had not been disturbed. He said that whether one party or the other had control of the government of New Granada did not affect the question; that France had not recognized Mosquera or his government, because there was an opposition in arms against him; or, in other words, there was a civil war between opposing parties; that, if the railroad were about to be interrupted or destroyed, he would not think it improper for the United States to interfere; but if matters remained now as they were a month since, when his advices were received, he thought it uncalled for at this time by any treaty stipulation. He referred, too, to the somewhat anomalous position of Mr. Herran, who made the call for interference, and who, he seemed to think, did not represent the government actually in power. He further said that, a few days since, the British ambassador had applied to them to know what view the French government took of this matter, and he had sent him, by way of reply, a copy of his late note to Mr. Mercier; that they had not, as yet, heard what action the British government had taken upon the question.

The above is the substance of our conversation. I should have asked from Mr. Thouvenel (as I had from Mr. Rouher) a written reply, but for the fact stated, that he had already written to Mr. Mercier. If you have occasion to communicate to the government of New Granada the view [Page 381] taken by France, a copy of this note, if asked for, will doubtless be supplied by Mr. Mercier.

I am, sir, your obedient servant,

WILLIAM L. DAYTON.

His Excellency Wm. H. Seward, Secretary of State, &c., &c., &c.
