The margins, stated honestly

The plot's working

Three limbs are comfortable; the west limb is half a mile, and its settler is named. The town point's margins inside the 1828 tract: NORTH, 5.57 miles south of the 1817 line as the Royce mapping draws it at this longitude (6.04 miles south of the county framework's rounded 41.616° N); the true Indiana–Michigan line stands about 15.9 miles north of the town, and the 1817 line is not the state line — the distinction the county's framework work settled and this plot depends on. SOUTH, 3.77 miles north of the mapped boundary, or 4.42 miles on the strict call of ten miles exactly: the mapped line runs about 0.65 miles north of the call at this longitude, a Royce placement variance printed here so no later worker mistakes the map for the instrument; it does not touch the verdict. EAST, not a live limb — the tract runs from the town's longitude east across the whole north of Indiana, more than 55 miles. WEST is the thinnest margin of the plot, and it is a derived line, not a surveyed one: the meridian due south from the head of the most easterly branch of the Kankakee. Three placements stand in the record. The digitized Royce polygon's edge at the town's latitude, bisected, flips from the 1832 cession to the 1828 between 86.28502° W and 86.28496° W — the town 0.50 miles east of the line. The North Liberty pass's mapped bisection put the line at about 86.29° W — the town 0.76 miles east. Its treaty-worker's call-by-call plot put the meridian at 86.305° W — the town 1.53 miles east. Every placement leaves the town inside the 1828 cession, and every placement is west of the town; a placement east of the town's own longitude is the only evidence that could disturb the taking, and nothing reached supports one. The evidence that would fix the true meridian is the same settler the sister build named: the General Land Office field notes and original survey record for the Kankakee headwaters. No candidate boundary falls between any two published town points — the whole spread of printed positions sits inside the same box.
