Fig. 149. (S. 1–1.) This is from Wisconsin. Such specimens are beautiful examples of high art in chipping. G. L. Collie’s collection, Beloit, Wisconsin. A similar specimen to Fig. 149 is in the collection of Mr. L. Simonton of Warren County, Ohio.
Fig. 150. (S. 1–1.) Black, opaque obsidian with double serration; notched for handle. Very delicate workmanship. Found by James A. Barr at the Stockton Channel mound.
Fig. 152. (S. 1–1.) Unknown form of chipped object. E. E. Baird collection, Poplar Bluff, Missouri.
Fig. 151. (S. 1–3.) “Stockton Curves.” Black obsidian, fine workmanship. James A. Barr’s collection.
Fig. 153. (S. 1–1.) To the right a scraper or knife of finely grained chocolate quartzite. At the left, the upper specimen is a knife of white chalcedony; the lower specimen, gray jasper, assuredly a handled knife, with tang so small that it must have been used on something easy to cut. Possibly a knife for opening fish, as it was found where trout are plentiful. Point broken, cutting edge unusually sharp. Collection of Luther A. Norland, La Jara, Colorado.
