The Secretary of State, to whom was referred the resolution of the Senate of the 10th instant, has the honor to report: That this department is not in possession of any names of persons in the United States who have, in any way or manner whatever, entered into, or countenanced the project or the views for the execution or attainment of which John Henry was, in the year 1809, employed by Sir James Craig; the said John Henry having named no person or persons as being concerned in the said project or views referred to in the documents laid before Congress on the 9th instant. Which is respectfully submitted,

JAMES MONROE.

The Message and documents having been read, Mr. Rhea made a motion to print them.

Mr. Pitkin said that he had no objection to the papers being printed, but that he rose to protest against the sentiments attributed in these papers to the Federal party, being considered as those of the citizens of the State which he had the honor to represent. He trusted it would not be believed that they had any knowledge of any mission of this kind from Canada, or from any other quarter.

It was the first time that he had heard that the opposition to the embargo in the States of Vermont or Massachusetts had any connection with the British Government, or with any project of a separation of the Union in any manner, much less under the agency of a British spy. So far as he could understand the papers from the first reading, Mr. P. said they did not intimate that any disclosure had been made to any individual of the United States by Mr. Henry of the object of his mission, or that his scheme had been advocated or supported by any one. And I trust no gentleman will take the character of the parties in any section of this country, from a man who it seems has proved a traitor to his own Government. So far as the statements made in these papers may be considered as involving the party in concert with the Federal party, in any scheme of co-operation with the British Government in dividing the Union, it is one of the grossest libels that ever was uttered. Nor do I feel willing to take the character of the people of this country from the mouth of this man. He does not stop at debasing the character of the people of this country, but he utters a libel against all parties and against the Government itself. He states that in the extra session of Congress in May, 1809, there were sixty-one votes against Mr. Madison, in consequence of his arrangement with Mr. Erskine; when we all know that the vote on the resolution approving of the President's conduct in that affair was no criterion by which to judge. While, therefore, gentlemen will not, as I presume they will not, place any confidence in the statements made by this man against themselves, and against those whom he styles Democrats, I trust they will be equally incredulous as to any statements he has made against those he has called Federalists, with respect to their co-operation with the British Government in dividing the Union. More especially as they come from one who, disappointed at not receiving the promised reward from his Government, has turned traitor to his employers.

Mr. Bibb said he agreed with the gentleman who just sat down on one point, that a full investigation ought to be had. It was due to the Congress, to our connections with Great Britain, that an inquiry should be made into the transaction now exposed to view; and, in addition to the motion for printing, he should move a reference of the Message to the Committee of Foreign Relations.

Mr. Gholson said it was a source of gratification to him, that, so far as the papers communicated by the President could be considered evidence at all, they were certainly highly honorable testimony in favor of the Eastern section of the Union. An emissary of great talents had been employed by the British in a nefarious scheme to dismember the United States, and to engender treason in the very bosom of our country: and yet, Mr. G. said, it does not seem that this spy has been able to connect with himself any citizen of the United States. If he had held correspondence with any persons of distinction, the presumption is their names would have been disclosed in the papers that have been read. Mr. G. was happy in cherishing the belief that the liberties of this country would always find a sufficient guarantee against machinations of this sort, in the patriotism of every portion of the Union. This communication, for which the House was indebted to the President, was highly interesting and important in one point of view. It demonstrated, as matter of fact, what had heretofore remained only speculation and conjecture, that the British Government has long meditated the separation of these States; and what is more, that they have actually attempted the execution of this wicked design, and have endeavored to convert our own citizens into traitors! He would say no more.

Mr. Quincy said he was much obliged to the gentleman last up for the view which he had taken of the subject. It had struck him previously with much force, and he meant to have taken the floor to have expressed it. If ever there had existed in the British Government, or any other Government, an idea that there was a party in this country who would associate with it to dissolve this Union, he thanked God that the project was exposed. If it was true, as these papers stated, that this man had been so employed, he thanked God that the mission had been detected. The Administration, in bringing the subject before the House, had done worthily, and the subject ought to be inquired into. What is the fact, admitting all that this person has said to be true? Why, that an agent from the British Government, under circumstances peculiarly auspicious and suitable to his purpose, goes to the spot which he represents as the hot-bed of opposition, to stir up disunion, and his papers do not contain an intimation that he dared to mention such an idea as that of a dissolution of the Union to any individual. No, sir; and I dare to say that he never did mention such a thing to any distinguished individual. As far as I know the sentiments of gentlemen in that quarter, they hold this Union dear, and look upon such a connection as is supposed in these papers with as much abhorrence as any man, however attached he may be to the administration of the Government. Whenever a dismemberment of the Union has been talked of, it has been with awe, and with a fear that the present course of public measures would lead to such an event, and not with a view to bring it about. Sir, I know that other ideas have been spread over the country for the purpose of serving party views. But here, in this temple of our liberties, let us reason with one another according to the evidence before us. I rejoice that the subject has been brought forward, and that an agent so peculiarly adapted to the business in which he was employed has not. been able to furnish any evidence of even the connivance of any individual at his mission.

Mr. Wright said that such an extraordinary communication as that just received from the President, reflecting so much on various sections and parties of the Union, required serious consideration before they consented to publish such gross abuse of every portion of our people. Gentlemen should reflect that this very disclosure might be one of the means used by this miscreant to divide this country. If he wished to promote division, how could he better attain his object than by denouncing the people of a particular section? Who is this man, and where is he? is an inquiry that ought to be made. I am not one of those who would, without inquiry, take the words of a spy, traitor, and villain, as truth. It might be well to print a sufficient number for the House, but no more until they knew more about it. However gentlemen in the Eastern States might have been dissatisfied at particular measures, the embargo law for instance, their opposition to them had arisen from their operation on their particular interests, and not that they had any disposition to sever themselves from the Union. This business had been very correctly communicated by the Executive to Congress; but they ought to act on it with temper, prudence, and coolness. Mr. W. protested against considering any such disposition as it attributed to a certain party to exist, particularly in the spot which has been frequently and emphatically styled the cradle of the Revolution. He could not feel the same disposition which some appeared to do, to give consequence to this affair.

Mr. Troup did not consider these papers as involving the character of any portion of our people. They appeared to him to be calculated merely to put the people on their guard against foreign emissaries or agents employed for the purpose of effecting a dismemberment of this Union. As to the opinions this person expresses of parties, &c., they are merely the individual speculations of this man, and cannot have much weight. But the documents have a most important bearing. They establish the fact that a foreign Government, on the eve of hostility with us, has for some time past employed an agent to foment divisions among us; and another fact, which, considered in connection with other circumstances, is of great importance. They show the deep-rooted hostility of this foreign power to our Republican Government and liberties—a hostility which could stop at nothing short of a dismemberment of the country. After the affair of the Wabash, when it was said that the Indians had been instigated by the same enemy to hostilities against us, the British Minister's choler rose; he denied the whole. He avails himself of suggestions in public prints to deny their statements; to state that so far from a disposition to stir up the Indians against us, the contrary was the fact; that, indeed, Sir James Craig has been intent on diverting Indian hostilities. Sir, may we not reasonably believe him to have fomented Indian hostilities in one part of the country, while in another he was promoting disunion in the body of the people? These, sir, are the only facts disclosed of importance; the only facts which would justify the publication of more than the ordinary number of copies.
