Article 14. - Boundaries.
Section 1. In order that the boundaries of the State may be known and
established, it is hereby ordained and declared, that the State of Indiana
is bounded, on the East, by the meridian line, which forms the western
boundary of the State of Ohio; on the South, by the Ohio river, from the
mouth of the Great Miami river to the mouth of the Wabash river; on the
West, by a line drawn along the middle of the Wabash river, from its
mouth to a point where a due north line, drawn from the town of
Vincennes, would last touch the north-western shore of said Wabash
river; and, thence, by a due north line, until the same shall intersect an
east and west line, drawn through a point ten miles north of the southern
extreme of Lake Michigan; on the North, by said east and west line, until
the same shall intersect the first mentioned meridian line, which forms the
western boundary of the State of Ohio.
Section 2. The State of Indiana shall possess jurisdiction and
sovereignty co-extensive with the boundaries declared in the preceding
section; and shall have concurrent jurisdiction, in civil and criminal cases,
with the State of Kentucky on the Ohio river, and with the State of Illinois
on the Wabash river, so far as said rivers form the common boundary
between this State and said States respectively.
