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is prevented altogether from admitting or assuming that the States referred to by them have, in law or in fact, withdrawn from the Federal Union, or that they could do so in the manner described by Messrs.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 can not 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 a duly verified copy of the paper be now delivered.

The Commissioners in reply to Mr. Seward.
