To the House of Representatives of the United States:
In compliance with a resolution of the House of Representatives of the 20th instant, I now transmit a copy of the message of President Jefferson to both Houses of Congress on the 18th of January, 1803, recommending an exploring expedition across this continent.* It will be perceived on the perusal of this message that it was confidential, for which reason the copy of it is now communicated in the same manner, leaving to the judgment of the House to determine whether any adequate reason yet remains for withholding it from publication. I possess no other document or information in relation to the same subject which I consider as coming within the scope of the resolution of the House.
JOHN QUINCY ADAMS.
