5. Compact blackstone, Livingston County. 6. Steatite, Madison County. 7. Greenstone, Franklin County. 8. Hard red material, Livingston County. 9. Blooded quartz, Hancock County. 10. Slate, black, Trigg County. 11. Blooded quartz, Oldham County. 12. Green banded slate, Madison County. 13. Quartz, Trigg County. These specimens, found in Kentucky, are beautiful, highly finished, and represent the acme of stone-age art in the problematical class. The double-winged crescents at the top on either side are to be noted. Also the fine crescent, no. 5. No. 9, of blooded quartz, is a type somewhat common in the South, but very seldom found in the Ohio Valley and never in the East, or west of a line drawn between Omaha, Nebraska, and Dallas, Texas. No. 13 is of that same beautiful blooded quartz, which material was selected by the natives because of its fine texture and brilliant colors. This plate emphasizes that while winged objects, as a general proposition, may be somewhat alike, yet in the detailed form and material they are different, and those of one section can be distinguished from those of another.

Found at Thornhill Lake, Volusia County, Florida. From “Certain Sand Mounds, St. Johns River, pt. II.” This is one of the angular Southern forms, with expanded wings. It is not of the butterfly type. It reminds one very strongly of a Wisconsin-Michigan form which is typified in Fig. 343. There are few of the winged stones found in Georgia, Florida, or Alabama. ] Figs. 343, 349, 357 illustrate the Wisconsin types. Other specimens from Ohio, Indiana, etc., illustrate the more widespread Wisconsin types. It often happens that a later tribe makes use of an object of ancient form and special purpose, for some service totally foreign to the mind of the original owner.
