MOBILE, a river of the United States of North America, in the state of Alabama, is formed by the united streams of Tombigby and Alabama rivers. The extreme north-west sources of Tombigbee are in the state of Mis sissippi, near the south line of Tennessee, from whence the different branches flow south-east into Alabama, where, uniting, they form the Tombigbee, which flows nearly due south to its junction with the Alabama, at N. Lat. 05'. The Tombigbee tectives, besides many lesser confluents, the Tuscaloosa, or Black Warrior, a large stream from the north-east. The entire length of the Tombigbee is about 300 miles, by comparative course.
The Alabama is formed by the united streams of the Coosa and Tallapoosa, which both rise in Georgia, and flowing to the south west, unite at N. Lat. 32° 23', and from thence to the junction with Tombigbee assumes the name of Alabama. The entire length of the Ala bama, from the sources of the Coosa to the head of Mo bile river, is, by comparative course, about four hundred miles. A considerable branch from the north, called the
Cahaba, enters the Alabama about one hundred miles, by the windings of the stream, below the junction of the Coosa and Tallapoosa. Cahaba, the seat of government for the state of Alabama, is situated at the mouth of the Cahaba river.
The river Mobile is about forty miles in length, from the head of Mobile bay to the junction of the Tombigbee and Alabama rivers. Within a very short distance of its head, the Mobile divides into two branches, that of Mobile proper to the west, and Tensaw to the cast. These never again reunite, but flow separately into Mo bile bay, with several inlets from one to the other. The islands enclosed between the main branches and the inlets are, in general, liable to inundation.
The Mobile river admits vessels of twelve feet draught in all its length ; the Tombigbee, those of five feet to Fort Stoddart ; and Mobile, those of about six feet to Fort Claiborne.
