A low, square, plainly-hewn stone, set near the summit of the eastern approach to the formidable natural fortress of Cumberland Gap, indicates the boundaries of-the three great States of Virginia, Kentucky and Tennessee. It is such a place as, remembering the old Greek and Roman myths and superstitions, one would recognize as fitting to mark the confines of the territories of great masses of strong, aggressive, and frequently conflicting peoples. There the god Terminus should have had one of his chief temples, where his shrine would be shadowed by barriers rising above the clouds, and his sacred solitude guarded from the rude invasion of armed hosts by range on range of battlemented rocks, crowning almost inaccessible mountains, interposed across every approach from the usual haunts of men.
