Fig. 144. (S. 1–2.) Unusual forms from Pennsylvania. H. K. Deisher’s collection, Kutztown, Pennsylvania.

Fig. 145. (S. 1–2.) Very rare form of chipped implement from California. H. K. Deisher’s collection, Kutztown, Pennsylvania.

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.

Fig. 147. (S. 1–1.) An object (knife) with sloping shoulder, well-defined blade, or cutting edge. Collection of Langdon Gibson, Schenectady, New York.

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).
