WASHINGTON, NOV. 27.

The following extract of a letter, is from a gentleman of the first respectability at Washington, Mississippi Territory, to his friend in this city, bearing date October 30, 1810.

"The situation of Florida most certainly claims the earliest possible attention of our government, for, unless they are adopted into our family of governments, there is much room to fear that one of the great belligerents of Europe will attempt to lay violent hands upon the provinces, to the incalculable injury of the U. States. Indeed I verily believe there is a strong party in that country in favour of its pupilage to a measure which could not be effected without a trouble and manly struggle by every real American within the province, aided by hundreds from without.

"It would be in vain for our government to forbid the interference of its citizens; their interests and their feelings are too strongly enlisted to be kept quiet spectators of such a struggle! During the late troubled state in that quarter, numbers of territorians were daily crossing and recrossing the line in anxious expectation of some military employment! The Conventionalists will again meet in Convention, in a few days, at Baton Rouge, and I think one of their first measures will be to adopt a constitution, bottomed upon their declaration, of independence; and in all probability they will set on foot an expedition against the Spanish garrisons on Mobile and Pensacola.

Notwithstanding these overt acts of self-government, I am well convinced that the Conventionalists would promptly and joyfully acquiesce in any claim of dominancy which the United States would set up.

"But upon this subject you will probably be much better informed, in a short time, by a messenger who will be sent by the Convention to our government."
