Figs. 110 to 134 show groups from various localities in the United States including specimens under various classifications previously described. Attention is called to the central specimen in the upper row of Fig. 110. It is a long, thin, leaf-like blade, slightly notched at one end. Fig. 95 presents several serrated Oregon points; and Fig. 138 shows nine objects from the Mandan village-sites, North Dakota. The Mandan points are nearly all triangular in form with square bases. That is, before being notched or barbed they were stemmed square, or at one end angular, and seldom with convex sides. Then the notches were cut, giving the appearance of a war-point with notches. A few Mandan objects have concave bases, prominent shoulders, or barbs, but the most of them were of the form shown in the lower specimen in Fig. 138. CHAPTER VIII UNUSUAL FORMS IN CHIPPED OBJECTS We have presented illustrations and brief descriptions of all forms classified by the Nomenclature Committee. There remain numbers of forms which do not fit in any of the divisions. Fig. 140 shows a long, pointed object, half-size. There are two distinct projections at the top; the base is concave. Such an implement would be classed as stemmed or not stemmed according to one’s point of view. But the exaggerated shoulders are the essential features, not the stem. [Illustration: FIG. 140. (S. 1–2.) Material: dark blue flint. W. P. Agee’s collection. Found near Hope, Arkansas. ] [Illustration: FIG. 141. (S. 1–1.) Drill-like object. There are really four barbs, or shoulders. Collection of E. E. Baird, Poplar Bluff, Missouri. ] [Illustration: FIG. 142. (S. 1–1.) Collection of Mr. Kendall. This is of expanding stemmed type, yet there is observed on the right side a projection intentionally made. A few such objects have been found, and their purpose must remain problematical. ] [Illustration: FIG. 143. (S. 1–1.) This figure is probably a knife. It was found by Mr. J. R. Smith in Rhode Island. It has a notch in the top, a large one in the side, and the cutting edge is beveled, or rather made sharply convex. Mr. Smith sent the specimen for examination. It shows evidence of considerable use. Such an object defies classification. ] [Illustration: FIG. 144. (S. 1–2.) Unusual forms from Pennsylvania. H. K. Deisher’s collection, Kutztown, Pennsylvania. ] [Illustration: FIG. 145. (S. 1–2.)
