For the rest, the works of the Mound Builders, except such as were too large to be destroyed by the farmer, have disappeared almost as wholly as the Mound Builders themselves. Their mole-like race threw up their ridges and banks and larger and lesser heaps, and then ceased from the face of the earth, as utterly as if they had burrowed into its heart. They may have fled before the ancestors of the savages whom our ancestors found here; they may have passed down peacefully into Mexico and built the cities which the Spaniards destroyed there. Or, they may have come up out of Mexico, and lost the higher arts of their civilization in our northern woods, warring with the wild tribes who were here before them. In either case, it is imaginable that the Mound Builders were of the same race as the ancient Mexicans and Peruvians, and it is probable that they were akin to the Zufiis of our own day. The snake dances of the Zufiis are a relic of the old serpent worship; and the fear and hate which the Zufiis bear the red savages of the plains may be another heritage from the kindred race which once peopled our Ohio valleys. II. OHIO AS A PART OF FRANCE. If the people of Ohio were Eskimos in the ages before history began, and then thousands of years after, but still thousands of years ago were Aztecs, there is no doubt that when history first knew of them they were Frenchmen. The whole Great West, in fact, was once as much a province of France as Canada; for the dominions of Louis XV. were supposed to stretch from Quebec to New Orleans, and from the Alleghanies to the Mississippi. The land was really held by savages who had never heard of this king; but that was all the same to the French. They had discovered the Great Lakes, they had discovered the Mississippi, they had discovered the Ohio; and they built forts at Detroit, at Kaskaskia, and at Pittsburg, as well as at Niagara; they planted a colony at the mouth of our mightiest river, and opened a highway to France through the Gulf of Mexico, as well as through the Gulf of St. Lawrence; and they proclaimed their king sovereign over all.
