SPECIAL MESSAGE.—January 28, 1807.

To the Senate and House of Representatives of the United States:—

By the letters of Captain Bissel, who commands at Fort Massac, and of Mr. Murrell, to General Jackson, of Tennessee, copies of which are now communicated to Congress, it will be seen that Aaron Burr passed Fort Massac on the 31st December, with about ten boats, navigated by about six hands each, without any military appearance, and that three boats with ammunition were said to have been arrested by the militia at Louisville.

As the guards of militia posted on various points on the Ohio will be able to prevent any further aids passing through that channel, should any be attempted, we may now estimate, with tolerable certainty, the means derived from the Ohio and its waters, toward the accomplishment of the purposes of Mr. Burr.
