Mr. Seward to Mr. Dayton.

No. 149.]

Sir: As you will be more particularly informed by papers sent herewith, New Orleans is opened to the mails. A collector has also proceeded there to take measures for opening that port. Other ports will be opened also. The Treasury, War, and Navy Departments are completing the details of preparation. The fall of New Orleans, Fort Macon, and Yorktown in rapid succession have produced a general expectation of peace. No one on either side of the contest dreams of peace otherwise than with the complete restoration of the Union. Indeed, the whole country feels that this consummation has actually begun. How strangely in contrast with this conviction are the coldness and indifference manifested by maritime powers, and the crowding of our coasts with contraband European vessels freighted with arms and munitions of war vainly consigned to the insurgents! France, Belgium, and Great Britain, while suffering the sorest privations, are, nevertheless, constantly sending hither on desperate ventures the means to protract the calamitous war they deprecate. We shall have peace and Union in a very few months, let France and Great Britain do as they may. We should have them in one month if either the Emperor or the Queen should speak the word and say, If the life of this unnatural insurrection hangs on an expectation of our favor, let it die. To bring the Emperor to this conviction is your present urgent duty. If successful in performing it, you will render a benefit to France worth more than any conquest, while you will direct a stream of healing oil upon the wounds of our own afflicted land. The President prays and trusts that you may succeed.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

William L. Dayton, Esq., &c., &c., &c.
