In case the authenticity of these relics be questioned, the facts in regard to them, so far as known, are here presented for reference. As to the two specimens from Sevierville, Tenn. (Plates LXXI and LXXII), the shadow of a doubt cannot be attached to them. Were there no record whatever of the time or place of discovery, the evidence upon the faces of the relics themselves would show satisfactorily that they are genuine. They were taken from the great mound, which I have called the McMahan Mound, at Sevierville, Tenn. This mound was opened in 1881 by one of our most experienced collectors, Dr. E. Palmer. The specimens when found were in a very advanced stage of decay, pitted, discolored, and crumbling, and had to be handled with the utmost care to prevent total disintegration. They were dried by the collector, immersed in a weak solution of glue, and forwarded immediately to the National Museum at Washington. In this mound a multitude of relics were found, a large number being of shell, many of which are figured and described in this paper. These two gorgets, as well as many others of more ordinary types were found on or near the breasts of skeletons, and it is highly probable that they were suspended about the necks of the dead just as they had been worn by the living. By accurately ascertaining the authenticity of one of these specimens we establish, so far as need be, the genuineness of all of the same class. If one is genuine that is sufficient; the others may or may not be so, without seriously effecting the questions at issue, yet the occurrence of duplicate or closely related specimens in widely separated localities furnishes confirmatory evidence of no little importance. I do not wish to be understood as casting a doubt upon any of the four specimens described, as I am thoroughly convinced that there is no cause for suspicion. The Missouri gorget, which has already been described and figured, was obtained by unknown persons in Southeastern Missouri. Several years back it came into the hands of Colonel Whitley, and from him it was obtained by its present owner, Professor Potter, of Saint Louis. There has never been a question as to its genuineness, and according to Professor Hilder, who saw it shortly after its discovery, the appearance and condition of the specimen were such that it could not have been of fraudulent manufacture. It was chalky and crumbling from decay, the lines of the design bearing equal evidence with the general surface of the shell of great age. Beside this, even if it were possible to produce such a condition in a recently carved shell, there existed no motive for such an attempt. Nothing was to be made by it; no benefit could accrue to the perpetrator to reward him for his pains, and, further, there was no precedent, there was extant nothing that could serve as a model for such a work.
