FIG. 146. (S. 1–1.) Peculiar object from F. Delaney’s collection. Fig. 140 and also Fig. 146 are similar specimens, one from W. P. Agee’s collection, Arkansas, and the other from the cabinet of F. Delaney, Rhode Island. In both these the barbs are purposely exaggerated and made the predominant feature of the specimen. It is easy to theorize that these were worked over from broken forms, which may or may not be the case. Fig. 140, Mr. Agee’s collection, has unusual, long, rounded shoulders, the edges beveled, and the angles are very marked. Both these specimens are interesting; similar ones are not frequently found. The above specimen is of mottled flint and was found in Pulaski County, Kentucky. ] [Illustration: FIG. 147. (S. 1–1.) An object (knife) with sloping shoulder, well-defined blade, or cutting edge. Collection of Langdon Gibson, Schenectady, New York. ] [Illustration: FIG. 148. (S. 1–2.) The curved knife shown above is from one of the altars of the Hopewell group, and is shown half-size. A number of these barbed knives, made of obsidian, were taken from the Hopewell effigy mound. The material is from Yellowstone Park, and must have been brought over twenty-five hundred miles (by canoe). ] [Illustration: 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. ] [Illustration: 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. ] [Illustration: FIG. 152. (S. 1–1.) Unknown form of chipped object. E. E. Baird collection, Poplar Bluff, Missouri. ] [Illustration: FIG. 151. (S. 1–3.) “Stockton Curves.” Black obsidian, fine workmanship. James A. Barr’s collection. ] [Illustration: 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. ]
