Memorandum.

DEPARTMENT OF STATE, WASHINGTON, March 15, 1861.

Mr. John Forsyth, of the State of Alabama, and Mr. Martin J.Crawford, of the State of Georgia, on the 11th inst., through the kind offices of a distinguished Senator, submitted to the Secretary of State their desire for an unofficial interview. This request was, on the 12th inst., upon exclusively public considerations, respectfully declined.

On the 13th inst., while the Secretary was preoccupied, Mr. A. D. Banks, of Virginia, called at this Department, and was received by the Assistant Secretary, to whom he delivered a sealed communication, which he had been charged by Messrs. Forsyth and Crawford to present to the Secretary in person.

In that communication Messrs. Forsyth and Crawford inform the secretary of State that they have been duly accredited by the Government of the Confederate States of America as commissioners to the Government of the United States, and they set forth the objects of their attendance at Washington. They observe that seven States of the American Union, in the exercise of a right inherent in every free people, have withdrawn, through conventions of their people, from the United States, reassumed the attributes of sovereign power, and formed a government of their own, and that those Confederate States now constitute an independent nation, de facto and de jure and possess a government perfect in all its parts, and fully endowed with all the means of self-support.

Messrs. Forsyth and Crawford, in their aforesaid communication, thereupon proceeded to inform the Secretary that, with a view to a speedy adjustment of all questions growing out of the political separation thus assumed, upon such terms of amity and good will as the respective interests, geographical contiguity, and the future welfare of the supposed two nations might render necessary, they are instructed to make to the Government of the United States overtures for the opening of negotiations, assuring this Government that the President, Congress, and the people of the Confederate States earnestly desire a peaceful solution of these great questions, and that it is neither their interest nor their wish to make any demand which is not founded in the strictest justice, nor do any act to injure their late confederates.

After making these statements, Messrs. Forsyth and Crawford close their communication, as they say, in obedience to the instructions of their Government, by requesting the Secretary of State to appoint as early a day as possible, in order that they may present to the President of the United States the credentials which they bear and the objects of the mission with which they are charged.

The Secretary of State frankly confesses that he understands the events which have recently occurred, and the condition of political affairs which actually exists in the part of the Union to which his attention has thus been directed, very differently from the aspect in which they are presented by Messrs Forsyth and crawford. He sees in them, not a rightful and accomplished revolution and an independent nation, with an established government, but rather a perversion of a temporary and partisan excitement to the inconsiderate purposes of an unjustifiable and unconstitutional aggression upon the rights and the authority vested in the Federal Government, and hitherto benignly exercised, as from their very nature they always must so be exercised, for the maintenance of the Union, the preservation of liberty, and the security, peace, welfare, happiness, and aggrandizement of the American people. The Secretary of State, therefore, avows to Messrs. Forsyth and Crawford that he looks patiently, but confidently, for the cure of evils which have resulted from proceedings so unnecessary, so unwise, so unusual, and so unnatural, not to irregular negotiations, having in view new and untried relations with agencies unknown to and acting in derogation of the Constitution and laws, but to regular and considerate action of the people of those States, in cooperation with their brethren in the other States, through the Congress of the United States, and such extraordinary conventions, if there shall be need thereof, as the Federal Constitution contemplates and authorizes to be assembled.

It is, however, the purpose of the Secretary of State, on this occasion, not to invite or engage in any discussion of these subjects, but simply to set forth his reasons for declining to comply with the request of Messrs. Forsyth and Crawford.

On the 4th of March instant, the then newly elected President of the United States, in view of all the facts bearing on the present question, assumed the Executive Administration of the Government, first delivering, in accordance with an early, honored custom, an inaugural address to the people of the United States. The Secretary of state respectfully submits a copy of this address to Messrs. Forsyth and Crawford.

A simple reference to it will be sufficient to satisfy these gentlemen that the Secretary of State, guided by the principles therein announced, is prevented altogether from admitting or assuming that the States referred to by them have, in law or in fact, withdrawn from the Federal Union, or that they could do so in the manner described by Messrs.Forsyth and Crawford, or in any other manner than with the consent and concert of the people of the United States, to be given through a National Convention, to be assembled in conformity with the provisions of the Constitution of the United States. Of course, the Secretary of State cannot act upon the assumption, or in any way admit that the so-called Confederate States constitute a foreign power, with whom diplomatic relations ought to be established.

Under these circumstances, the Secretary of State, whose official duties are confined, subject to the direction of the President, to the conducting of the foreign relations of the country, and do not at all embrace domestic questions, or questions arising between the several States and the Federal Government, is unable to comply with the request of Messrs. Forsyth and Crawford, to appoint a day on which they may present the evidences of their authority and the objects of their visit to the President of the United States. On the contrary, he is obliged to state to Messrs. Forsyth and Crawford that he has no authority, nor is he at liberty, to recognize them as diplomatic agents, or hold correspondence or other communication with them.

Finally, the Secretary of State would observe that, although he has supposed that he might safely and with propriety have adopted these conclusions, without making any reference of the subject to the Executive, yet, so strong has been his desire to practice entire directness, and to act in a spirit of perfect respect and candor toward Messrs. Forsyth and Crawford, and that portion of the people of the Union in whose name they present themselves before him, that he has cheerfully submitted this paper to the President, who coincides generally in the views it expresses, and sanctions the Secretary's decision declining official intercourse with Messrs. Forsyth and Crawford.

April 8, 1861.

The foregoing memorandum was filed in this Department on the 15th of March last. A delivery of the same to Messrs. Forsyth and Crawford was delayed, as was understood, with their consent. They have now, through their secretary, communicated their desire for a definite disposition of the subject. The Secretary of State therefore directs that adult verified copy of the paper be now delivered.
