By the letters of Capt Bissel who commands at Fort Massac, and of mr Murrell, to General Jackson of Tennissee, copies of which are now communicated to Congress, it will be seen that Aaron Burr past Fort Massac on the 31st. of 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 of 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 it’s waters towards the accomplishment of the purposes of mr Burr.
