After they discovered the mines and began to work them, their progress could not have been rapid. As their open trenches and pits could be worked only in the summers, and by methods that made their operations much slower than those of modern miners, no great advance of their work was possible during the working time of each season; and yet remains of their mining works have been discovered wherever mines have been opened in our day; and, as previously stated, they are known to exist in heavy forests, where the modern mining works have not yet been established. There is nothing to indicate that they had settlements any where in the mining region. Colonel Whittlesey, and others whose study of the subject gives their opinion much weight, believe the Mound-Builders went up from the settlements farther south in the summers, remained in the copper region through the season, and worked the mines in organized companies until the advance of winter terminated their operations.

Colonel Whittlesey says: "As yet, no remains of cities, graves, domiciles, or highways have been found in the copper region;" and adds, " as the race appears to have been farther advanced in civilization than their successors, whom we call aborigines, they probably had better means of transportation than bark canoes." It may be said, also, that the accumulations called wealth were necessary to make this regular and systematic mining possible. Without these they could not have provided the supplies of every kind required to sustain organized companies of miners through a single season. A great many

summers must have passed away before such companies of miners, with all needed tools and supplies, could have made their works so extensive by means of such methods as they were able to use.

They probably occupied the country on the Gulf and Lower Mississippi much longer than any other portion of the great valley. Their oldest and latest abandoned settlements appear to have been in this region, where, we may reasonably suppose, they continued to dwell long after they were driven from the Ohio Valley and other places at the north.

The Natchez Indians found settled on the Lower Mississippi may have been a degenerate remnant of the Mound-Builders. They differed in language, customs, and condition from all other Indians in the country; and their own traditions connected them with Mexico. Like the Mexicans, they had temples or sacred buildings in which the "perpetual fire" was maintained. Each of their villages was furnished with a sacred building of this kind. They had also peculiarities of social and political organization different from those of other tribes. They were sun-worshipers, and claimed that their chief derived his descent from the sun. The Natchez were more settled and civilized than the other Indians, and, in most respects, seemed like another race. One learned investigator classes them with the Nahuatl or Toltec race, thinks they came from Mexico, and finds that, like the ancient people of Panuco and Colhuacan, they had the phallic ceremonies among their religious observances. Their history can not be given, and there is little or

nothing but conjecture to connect them with the MoundBuilders. The Natchez were exterminated in 1730 by the French, whom they had treated with great kindness. Of the few who escaped death, some were received among the Chickasaws and Muskogees, but more were sent to Santo Domingo and sold as slaves.

No view that can be taken of the relics left by the Mound-Builders will permit us to believe their stay in the country was short. Any hypothesis based on the shortest possible estimate of the time must count the years by centuries.

III.

WHO WERE THE MOUND-BUILDERS?

THIS ancient people, whose remains indicate unity and civilization, must have been organized as a nation, with a central administration which all recognized. They must have had a national name, but nobody can tell certainly what it was. No record or tradition has preserved it, unless discovery of it can be made in a national designation found, without clear explanation, in the old books and traditions of Central America, and applied to some country situated at a distance from that part of the continent in the northeast. These old books and traditions mention "Huehue-Tlapalan" as a distant northeastern country, from which the Nahuas or Toltecs came to Mexico; and Brasseur de Bourbourg, who has translated one of the old books and given much attention to others, supposes the Toltecs and the Mound-Builders to be the same people, or did suppose this previous to the appearance of his "Atlantic theory." But this point will be more fully considered when we come to the Central American antiquities.

Some antiquaries suggest that the Mound-Builders were the people called "Allighewi" in old traditions of the Iroquois, but we have nothing to make this very probable. The Iroquois were somewhat superior to the

other great family of barbarous Indians in organization for the business of fighting. There are some reasons for believing they came to the lake regions and the Ohio Valley much earlier than the Algonquin branch of the wild Indian race. It is permissible, at least, to conjecture, if one feels inclined to do so, that it was the Iroquois migration from the northwest, or that of the great family to which the Iroquois family belonged, which expelled the Mound-Builders from their border settlements, cut them off from the copper mines, and finally pushed them down the Mississippi; but nothing more than conjecture is possible in this case, and the supposition gives the Iroquois migration a greater antiquity than may be allowable. Moreover, the traditionary lore of the wild Indians had nothing to say of the Mound-Builders, who appear to have been as unknown and mysterious to these Indians as they are to us.

NOT ANCESTORS OF THE WILD INDIANS.

Some inquirers, not always without hesitation, suggest that the Indians inhabiting the United States two hundred years ago were degenerate descendants of the Mound-Builders. The history of the world shows that civilized communities may lose their enlightenment, and sink to a condition of barbarism; but the degraded descendants of a civilized people usually retain traditional recollections of their ancestors, or some traces of the lost civilization, perceptible in their customs and their legendary lore. The barbarism of the wild Indians of North America had nothing of this kind. It was orig
