The boundaries of this state are established and declared to be as follows: Beginning at the point where the thirty-first degree of north latitude crosses the Perdido River; thence east to the western boundary line of the State of Georgia; thence along said line, to the southern boundary line of the State of Tennessee; thence west along the southern boundary line of the State of Tennessee, crossing the Tennessee River, and on to the second intersection of said river by said line; thence up said river to the mouth of Big Bear Creek; thence by a direct line to the northwest corner of Washington county, in this state, as originally formed; thence southerly along the line of the State of Mississippi to the Gulf of Mexico; thence eastwardly, including all islands within six leagues of the shore, to the Perdido River; and thence up the said river to the beginning.

The boundary line between Alabama and Georgia commences on the west side of the Chattahoochee River, at the point where it enters the State of Florida; from thence up the river, along the western bank thereof, to the point on Miller's Bend, next above the place where the Uchee creek empties into such river; thence in a direct line to the Nickajack.

The boundary line between Alabama and Florida is the line commonly known as the 'mound line,' or 'Ellicott's Line,' as distinguished from a blazed line known as the 'upper' or 'Coffee Line,' commencing at a point on the Chattahoochee River, near a place known as 'Irwin's Mills'; and from thence to the Perdido River, marked the whole distance by blazes on the trees and by mounds of earth, at distances of about one mile.

(a) The State of Alabama hereby ratifies, confirms and adopts the recommendations of the joint committee heretofore appointed by the Governor of Florida and the Governor of Alabama to locate and mark the boundary line between the said states at the mouth of the Perdido River and adjacent thereto. Said committee consists of Honorable Richard W. Ervin, Honorable Richard H. Simpson, Honorable Philip D. Beall and Honorable F. C. Elliot, all on the part of the State of Florida, and Honorable Earl M. McGowin, Honorable W. C. Pruett and Honorable William N. McQueen, all on the part of the State of Alabama.

(1) The middle of the Perdido River at its mouth, as defined by the constitutions of the States of Alabama and Florida, is at latitude 30 deg 16' 53' north and longitude 87 deg 31' 06' west as the control point;

(2) That the boundary line at the mouth of Perdido River is fixed, as nearly as may be, in the axis of the mouth of said river, passing through the control point and running north and south and having as its northern terminus a point of latitude 30 deg 17' 02' north and longitude 87 deg 31' 06' west, and as its southern terminus a point 1,000 feet due south of the control point;

(3) That from the northern terminus of the boundary line at the mouth of the river, the boundary up the lower portion of said river be a straight line to a point at latitude 30 deg 18' 00' north, longitude 87 deg 27' 08' west, thence by a straight line to a point in the center line of the Intracoastal Canal at longitude 87 deg 27' 00' west;

(4) That the seaward boundary between Florida and Alabama extends from the south end of the boundary line at the mouth of Perdido River, thence south 0 deg 01' 00' west to the seaward limit of each respective state;

(5) And shall be deemed, taken and declared, and is hereby deemed, taken and declared, to be the boundary line between the states of Florida and Alabama, at the mouth of the Perdido River and adjacent thereto, and shall be deemed and taken as such by the authorities and people of this state.
