Before leaving the subject of effigy-mounds, we must refer to some instances of their presence in other localities. This cut is an eagle effigy discovered in Georgia. Only one other instance, also occurring in Georgia, is known of effigy-mounds in the South. Measured from tip to tip of the wings, the bird, in this case, is one hundred and thirty-two feet. This structure is composed of stones, and a singular feature is the surrounding circle of stone.53

Several examples of effigy-mounds are found in Ohio. The most notable one is that known as the Great Serpent Mound, in Adanis County. We give an illustration of it. The entire surrounding country is hilly. The effigy itself is situated on a tongue of land formed by the junction of a ravine with the main branch of Brush Creek, and rising to a height of about one hundred feet above the creek. Its form is irregular on its surface, being crescent-shaped, with the point resting to the north-west. We give in a note some of the dimensions. The figure we give of this important effigy is different from any heretofore presented. We are indebted for the plan from which the drawing was made to Rev. J. P. MacLean, of Hamilton, Ohio. Mr. MacLean is a well-known writer on these topics. During the Summer of 1884, while in the employ of the Bureau of Ethnology, he visited the place, taking with him a thoroughly competent surveyor, and made a very careful plan of the work for the Bureau. All the other figures published represent the oval as the end of the works. Prof. Putnam, who visited the locality in 1883, noticed, between the oval figure and the edge of the ledge, a slightly raised, circular ridge of earth, from either side of which a curved ridge extended towards the sides of the oval figure. Mr. MacLean’s researches and measurements have shown that the ridges last spoken of are but part of what is either a distinct figure or a very important portion of the original figure. As figured, it certainly bears a very close resemblance to a frog, and such Mr. MacLean concludes it to be.

There is both a similarity and a difference between this work and those of Wisconsin. The fact that it occurs isolated, the other effigies in Ohio being many miles away, shows that some special purpose must have been subserved by it. There the great numbers gave us a hint as to their purpose. In this case, however, nearly all observers conclude that it was a religious work. Mr. MacLean, after describing these three figures, propounds this query: “Does the frog represent the creative, the egg the passive, and the serpent the destructive power of nature?” Not a few writers, though not acquainted with the presence of the frog-shaped figure, have been struck with the combination of the egg and the serpent, that plays such an important part in the mythology of the Old World. We are told that the serpent, separate or in combination with the circle, egg, or globe, has been a predominant symbol among many primitive nations. “It prevailed in Egypt, Greece, and Assyria, and entered widely into the superstitions of the Celts, the Hindoos, and the Chinese.” “Wherever native religions have had their scope, this symbol is sure to appear.”54

Even the Indians have made use of this symbol. On Big Medicine Butte, in Dakota Territory, near Pierre, is a train of stones arranged in the form of a serpent, which is probably the work of the Sioux Indians. Around about on the hill is the burying-ground of their chiefs. This was to them sacred ground, and no whites were allowed near. The stones are about the size of a man’s head, and are laid in two rows, from one to six feet apart. The length in all is three hundred and fifty feet, and at the tail, stones, to represent rattles, are rudely carved. The eyes are formed by two big red bowlders. No grass was allowed to grow between the two rows of stone.55

It seems reasonable to suppose that the few isolated effigy mounds we have outside of Wisconsin were built to subserve a different purpose than those in that State. Mr. Peet has made some remarks on their probable use that seem to us to cover the ground, and to do away with any necessity of supposing on the part of its builders an acquaintance with Old World mythologies. Nature worship is one of the earliest forms of worship. The prominent features of a landscape would be regarded as objects of worship. Thus, for example, the island of Mackinac resembles in its outline the shape of a turtle; so the island was regarded as sacred to the turtle, and offerings were made to it. A bluff on the same island at a distance resembles a rabbit; accordingly, it was called by that name, and offerings were made to it. It is quite natural that the effigy-mound builders should seek to perpetuate by effigy some of these early traditions.

In the case of the Big Serpent mound this point is worth considering. The ridge on which it stands is not only in the midst of a wild, rough region, but is so situated that it commands a wide extent of country. In shape this tongue of land is also peculiar. It is a narrow, projecting headland, and would easily suggest the idea of a serpent or a lizard. “This, with the inaccessibility of the spot, would produce a peculiar feeling of awe, as if it were a great Manitou which resided there; and so a sentiment of wonder and worship would gather around the locality. This would naturally give rise to a tradition, or would lead the people to revive some familiar tradition and localize it.”56 The final step would be to make an effigy.

It seems to us very hazardous to draw any conclusions as to the religious beliefs of the Mound Builders from this effigy, or combinations of effigies. It also seems to us reasonable to suppose that but one figure was intended to be represented. A very slight prolongation of the serpent’s jaws and the limbs of the frog would connect them, in which case we would have some amphibious creature with an unduly extended tail, or perhaps a lizard. We must remember that the whole figure has been plowed over once or twice, so that we are not sure of the original outlines. We can not tell why they should represent a portion of the body as hollow, but neither can we tell why the head of the supposed serpent should be represented as hollow. We do not find any important earth-works near here. The hill on which it is placed commands a very extensive view of the surrounding country. Within the oval a pile of stones showed evidence of a long-continued fire, which would indicate that this was also a signal-mound. Prof. Putnam thinks it probable that there was a burial place between it and the large conical mound not far away.57

In the vicinity of Newark, Ohio, are two examples of effigy mounds. This cut represents what is called the alligator mound, but it is probably the effigy of a lizard. The position which this mound occupies is significant. It is on the very brow of a hill about two hundred feet high, which projects out into a beautiful valley. The valley is not very wide. Directly across was a fortified camp, in the valley below it was a circular work, and a short distance below on another projecting headland was a strongly fortified hill. The great works at Newark were six miles down the valley, but were probably in plain view. That it was perhaps a signal station, is shown by the presence of traces of fire.
