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.
