It is hereby ordained and
declared that the state of Wisconsin doth consent and accept of
the boundaries prescribed in the act of congress entitled “An act
to enable the people of Wisconsin territory to form a constitution
and state government, and for the admission of such state into
the Union,” approved August sixth, one thousand eight hundred
and forty−six, to wit: Beginning at the northeast corner of the
state of Illinois—that is to say, at a point in the center of Lake
Michigan where the line of forty−two degrees and thirty minutes
of north latitude crosses the same; thence running with the
boundary line of the state of Michigan, through Lake Michigan,
Green Bay, to the mouth of the Menominee river; thence up the
channel of the said river to the Brule river; thence up said last−
mentioned river to Lake Brule; thence along the southern shore
of Lake Brule in a direct line to the center of the channel between
Middle and South Islands, in the Lake of the Desert; thence in
a direct line to the head waters of the Montreal river, as marked
upon the survey made by Captain Cramm; thence down the main
channel of the Montreal river to the middle of Lake Superior;
thence through the center of Lake Superior to the mouth of the
St. Louis river; thence up the main channel of said river to the
first rapids in the same, above the Indian village, according to
Nicollet’s map; thence due south to the main branch of the river
St. Croix; thence down the main channel of said river to the Mississippi;
thence down the center of the main channel of that river
to the northwest corner of the state of Illinois; thence due east
with the northern boundary of the state of Illinois to the place of
beginning, as established by “An act to enable the people of the
Illinois territory to form a constitution and state government, and
for the admission of such state into the Union on an equal footing
with the original states,” approved April 18th, 1818.
