Although both the mound and pipes have been referred in turn to the peccary, the tapir, and the armadillo, it is safe to exclude these animals from consideration. It is indeed perhaps more likely that the ancient inhabitants of the Upper Mississippi Valley were autoptically acquainted with the mastodon than with either of the above-named animals, owing to their southern habitat.
Referring to the possibility that the mastodon was known to the Mound-Builders, it is impossible to fix with any degree of precision the time of its disappearance from among living animals. Mastodon bones have been exhumed from peat beds in this country at a depth which, so far as is proved by the rate of deposition, implies that the animal may have been alive within five hundred years. The extinction of the mastodon, geologically speaking, was certainly a very recent event, and, as an antiquity of upwards of a thousand or more years has been assigned to some of the mounds, it is entirely within the possibilities that this animal was living at the time these were thrown up, granting even that the time of their erection has been overestimated. It must be admitted, therefore, that there are no inherent absurdities in the belief that the Mound-Builders were acquainted with the mastodon. Granting that they may have been acquainted with the animal, the question arises, what proof is there that they actually were? The answer to this question made by certain archæologists is—the Elephant Mound, of Wisconsin.

Recalling the fact that among the animal mounds many nondescript shapes occur which cannot be identified at all, and as many others which have been called after the animals they appear to most nearly resemble, carry out their peculiarities only in the most vague and general way, it is a little difficult to understand the confidence with which this effigy has been asserted to represent the mastodon; for the mound (a copy of which as figured in the Smithsonian Annual Report for 1872 is here given) can by no means be said to closely represent the shape, proportions, and peculiarities of the animal whose name it bears. In fact, it is true of this, as of so many other of the effigies, the identity of which must be guessed, that the resemblance is of the most vague and general kind, the figure simulating the elephant no more closely than any one of a score or more mounds in Wisconsin, except in one important particular, viz, the head has a prolongation or snout-like appendage, which is its chief, in fact its only real, elephantine character. If this appendage is too long for the snout of any other known animal, it is certainly too short for the trunk of a mastodon. Still, so far as this one character goes, it is doubtless true that it is more suggestive of the mastodon than of any other animal. No hint is afforded of tusks, ears, or tail, and were it not for the snout the animal effigy might readily be called a bear, it nearly resembling in its general make-up many of the so-called bear mounds figured by Squier and Davis from this same county in Wisconsin. The latter, too, are of the same gigantic size and proportions.
If it can safely be assumed that an animal effigy without tusks, without ears, and without a tail was really intended to represent a mastodon, it would be stretching imagination but a step farther to call all the large-bodied, heavy-limbed animal effigies hitherto named bears, mastodons, attributing the lack of trunks, as well as ears, tusks, and tails, to inattention to slight details on the part of the mound artist.
It is true that one bit of good, positive proof is worth many of a negative character. But here the one positive resemblance, the trunk of the supposed elephant, falls far short of an exact imitation, and, as the other features necessary to a good likeness of a mastodon are wholly wanting, is not this an instance where the negative proof should be held sufficient to largely outweigh the positive?
In connection with this question the fact should not be overlooked that, among the great number of animal effigies in Wisconsin and elsewhere, this is the only one which even thus remotely suggests the mastodon. As the Mound Builders were in the habit of repeating the same animal form again and again, not only in the same but in widely distant localities, why, if this was really intended for a mastodon, are there no others like it? It cannot be doubted that the size and extraordinary features of this monster among mammals would have prevented it being overlooked by the Mound-Builders when so many animals of inferior interest engaged their attention. The fact that the mound is a nondescript, with no others resembling it, certainly lessens the probability that it was an intentional representation of the mastodon, and increases the likelihood that its slight resemblance was accidental; a slide of earth from the head, for instance, might readily be interpreted by the modern artist as a trunk, and thus the head be made to assume a shape in his sketch not intended by the original maker. As is well known, no task is more difficult for the artist than to transfer to paper an exact copy of such a subject. Especially hard is it for the artist to avoid unconsciously magnifying or toning down peculiarities according to his own conceptions of what was originally intended, when, as is often the case, time and the elements have combined to render shape and outlines obscure. Archæologic treatises are full of warning lessons of this kind, and the interpretations given to ancient works of art by the erring pencil of the modern artist are responsible for many an ingenious theory which the original would never have suggested. It may well be that future investigations will show that the one peculiarity which distinguishes the so-called Elephant Mound from its fellows is really susceptible of a much more commonplace explanation than has hitherto been given it.
