Mr. Charles C. Jones notes a discovery of a more suggestive character, due also to the search for gold. In the state of Georgia the river Chattahoochee flows through an auriferous region of the Nacoochee valley. From time to time the gold-diggers have made extensive cuttings through the soil and underlying drift-gravel, down to the slate-rock upon which it rests. During one of these excavations, at a depth of some nine feet, intermingled with the gravel and boulders of the drift, three large flint implements were found, measuring between three and four inches in length, and “in material, manner of construction, and appearance so nearly resembling some of the rough so-called flint hatchets belonging to the drift-type that they might very readily be mistaken the one for the others.”[27] With those may not unfitly be classed a large implement of hornstone, now in the collection of the Scottish Antiquaries, obtained by me from a dealer in Indian curiosities at Lewiston in the State of New York, where it was said to have been found at a great depth when sinking a well. Its form, though common enough among the implements of the American Mound-Builders, rarely, if ever, occurs on so large a scale in Europe, except among palæolithic remains. Ovoid discs of the same class attracted the attention of the Rev. J. MacEnery in his early explorations of Kent’s Cavern, and have anew been brought to light in the recent systematic researches there. Mr. Evans figures one found there in 1866 (Fig. 3), somewhat smaller, and more ovoid in outline, but of the same type. The Lewiston implement is shown in Fig. 2. It has been reduced to the present shape by comparatively few strokes; and on the reverse side it appears as if broken off by a final ill-directed blow. One edge is worn and fractured as if by frequent use. Unfortunately more minute information of the locality and the circumstances attendant on its discovery could not be obtained. But even if it be regarded as only a stray relic of the same class as those hereafter described among the ancient mound deposits of Wisconsin and Ohio, it possesses a novel interest from its discovery near the banks of the Niagara River, where no traces of the Mound-Builders or their arts occur. Mr. Evans permits me to introduce here the analogous example from Kent’s Cavern. It is of grey cherty flint, and chipped on both faces with more than wonted care. Though smaller than the Lewiston implement, the difference is only about half an inch; the larger of the two being a little over five inches long. I have purposely engraved the Lewiston disc on a large scale, in order to suggest more clearly the proportions of this class of implements; and to show the close analogy traceable between those of the American continent, and the European disclosures of the river and cave drift.
