FIG. 333. (S. 1–4.) Northern Illinois and northern Indiana types, from W. A. Holmes’s collection, Chicago. The winged type and also several that defy classification are present; notably, those on the upper row, the heart-shaped objects at either end, and the central unknown form with three perforations. The heart-form is occasionally found in the United States, but is rare. Just what significance it carries, I am unable to state. ] [Illustration: FIG. 334. (S. about 1–3.) A group of problematical forms, from the collection of Leslie W. Hills, Fort Wayne, Indiana. Most of these are in banded slate, although two are in granite. They will fall under three or four subdivisions of the classification. ] [Illustration: FIG. 335. (S. 1–1.) Problematical forms found in Cumberland County, New Jersey. The smaller one appears to be finished and is highly polished. The larger one is unfinished. The hole is drilled about halfway through, leaving a projection which indicates that the boring was done with a hollow instrument, probably a reed. These specimens are in the collection of George Hampton, Bridgeton, New Jersey. ] [Illustration: FIG. 336. (S. 1–1.) Side view of the large form in Fig. 352. George Hampton’s collection. ] [Illustration: FIG. 337. (S. 2–3.) These are reproduced from plates illustrating Dr. Wm. M. Beauchamp’s “Polished Stone Articles used by the New York Aborigines,” New York State Museum _Bulletin_, vol. 4, no. 18. They have been drawn, which shows the bands in the stone better than do half-tones. These types are found in New York State and Canada, Ohio, and Indiana. As one passes into Michigan or south of Kentucky, the forms and materials change. Attention is called to the central object, perforated on either side. This was originally a winged object, but becoming broken was perforated after the manner of a tablet and used in a way different from that the original form would indicate. It must be observed, in studying these problematical forms, that the perforations or drilling are even in all winged types and the large objects, but in the flat tablets the holes were rimmed out, and are wide on the face, and small on the reverse side. ] “Next from the right is a beautiful article and comes from Fabius or Pompey, much resembling one in the State Museum from that vicinity. It is made of a beautiful olive-green striped slate, and in form is like a slender pickaxe, having a central ridge along both sides, from end to end. Each end has a slight projection. In the centre, on one side, is a partially effaced ornament. It is seven inches wide by one and one fourth deep, and the orifice is nine sixteenths of an inch in diameter. No finer example of this form is on record.
