Information has been received thro’ a channel justly claiming attention, that the people of West Florida meditate an effort to liberate themselves from the Spanish Government; and that with this view it is intended in case the pulse of this Government does not promise a taking them by the hand, to address themselves to the British Government. No doubt is entertained of the ease with which the Spanish Garrisons can be overpowered. All the external aid desired, relates solely to a subsequent support against the force which may be employed by Spain to regain possession.
