Summary

Joseph McKenna North Carolina v. Tennessee — Opinion of the Court

Imagination is not proof, and, we repeat, whatever might be said of any particular piece of evidence standing by itself, their union and concurrence amount to demonstration. And, we repeat, it must have been supposed by the states when they constituted the commission that judgment would have to be exercised, and, when exercised, should be binding. The contention of North Carolina is therefore sustained by the proof as to Slick Rock basin.

Joseph McKenna North Carolina v. Tennessee — Opinion of the Court

But the fact cannot be conceded. The cession act is very general and necessarily demanded definition to satisfy the requirements of a boundary line,-a line not only necessary to mark private property, but political jurisdiction. This was realized and commissioners were appointed to run and settle the line exactly. Their work as executed was confirmed by the states.
The considerations which determine decision upon the contentions of the states as to the Slick Rock basin apply to the Tellico territory. Indeed, they make more strongly against the Tennessee contention.

Joseph McKenna North Carolina v. Tennessee — Opinion of the Court

In pursuance of the authority the commissioners appointed by the states settled the line from the east to a point on the Great Iron or Smoky mountain west of the Pigeon river, marked by a stone set up on the north side of the Cataloochee Turnpike road, about due north from the present town of Waynesville, in Heywood county, North Carolina, and about 6 miles east of the point where the Tennessee river passes through the mountain range, leaving the line to the southern boundary of the states unmarked.
