Inclosed is an extract of a letter which I received by the last southern mail to this place, from Major James Seagrove.

The letter was Written on a supposition that Congress would be immediately called, and that I should have it in my power personally to convey to you its contents. It appears at present that Congress will not be in Session for some time, deeming the information which the letter gives of moment, as it Regards a very exposed point of our Nation. I have not delayed to make you acquainted with it—it seems to me that a few Artillery men with two gun boats is the least which that place ought to have. The gun boats need not have their full Complement of men, an Officer to command and enough to work her is all that would be wanted, for our Citizens when necessity should Require, would give every aid, and assistance in their power.

I have the honor to be, very Respectfully Your Mo. Ob. Sert.
