If we examine the various groups scattered throughout the State, this belief is strengthened. It is found, for instance, in nearly every group, that some one effigy is the principal one, and is placed in a commanding position, about which the other forms are arranged. It is also thought that the same effigy is the principal or ruling effigy over a wide district. In illustration of this, it can be stated that in the south-eastern part of the State the turtle is always the ruling effigy. In any group of effigies it is the principal one. It seems to watch over and protect the others. In subordination to it are such forms as the lizard, hawk, and pigeon. Passing to the North, the turtle is no longer the important figure. It is replaced by the wolf, or wild-cat. This is now the principal form, and if the turtle is sometimes present, it is of less importance.
So marked is the fact we have just stated that Mr. Peet says, “that sometimes this division assumes almost the character of a river system, and thus we might trace what seems to be the beginning in this country of that which prevailed on classic soil and in Oriental regions—namely, river gods and tutelar divinities of certain regions, each tribal divinity having its own province, over which it ruled and on which it left its own form or figure as the seal of its power and the emblem of its worship.”50
Looking for some explanation of this, we may find a key in the known customs of various Indian tribes, and the lower races of men. It is known that a tribe of Indians is divided into smaller bands, which are called gens or clans. A gens may consist of several hundred persons, but it is the unit of organization. It takes the place of a family among civilized people. These various bands are generally named after some animal. In the beginning these names may have been of no special significance, but in course of time each band would come to regard themselves as descendants of the animal whose name they bore. Hence the animal itself would be considered sacred in their eyes, and its life would seldom be taken by members of that gens.
The animal thus honored by the gens was, in the Indian dialect, the totem of the clan. This organization and custom we find running all through the Indian tribes. In many tribes the Indians were wont to carve a figure of their totem on a piece of slate, or even to carve a stone in the shape of the totem, which carved or sculptured stone they wore as an ornament, or carried as a charm to ward off evil and bring them good luck.51 We need only suppose that this system was very fully developed among the Mound Builders of Wisconsin, to see what important bearing it has on these effigy mounds.
A tribe located on one of the fertile river valleys of Wisconsin was composed of various gens or clans. On some common point in proximity to their villages, or some spot which commanded a wide view of the surrounding country, each gens would rear an effigy of its totem, the animal sacred to them. In every tribe some gens would be the most powerful, or for some cause the most respected, and its totem would be given in the largest effigy, and would be placed in the most commanding position. In a different locality some other tribe would be located, and some other totem would be regarded as of the most importance.
In this light effigy-mounds are not mere representatives of animal forms. They are picture-writings on a gigantic scale, and are the source of much true history. They tell us of different tribes, the clans which composed them, the religious beliefs, and the ruling gens of the tribe. Contemplating them, we seem to live again in the far-off past. The white man disappears; waving forests claim their ancient domain, and the rivers, with a more powerful current, roll in their olden channels. The animals whose forms are imaged here, go trooping through the forest or over the fertile bottom lands. The busy scenes of civilization give place to the placid quiet of primeval times, and we seem to see peaceful tribes of Mound Builders paying a rude veneration to their effigy-gods, where now are churches of a more soul-satisfying religion.
But there is still another point to be learned from an examination of these ancient mounds. Not only are they totems of the tribes, but they were looked on in some sense as being guardian divinities, with power to protect the homes of the tribe. This is learned by studying the location in which they are placed. They occupy all points of observation. In other parts of the Mound Builders’ country, wherever we find signal-mounds we find corresponding positions in Wisconsin occupied by groups of effigy-mounds, or if one only is present, it is always the one which, from the considerations we have stated, was regarded as the ruling effigy of that section. It is as if their builders placed them as sentinels to guard the approaches to their homes, to give warning of the arrival of hostile bands. This is further borne out by finding that mounds placed in such positions frequently show evidence of the action of intense fire, and so we conclude they were used as signal stations also. So we need not doubt but that the region thus watched over by these effigy-mounds, group answering to group along the river banks, or in the valleys below, was at times lit up by the signal fires at night; or the warning column of smoke by day betokening the presence of dancer.52
