An additional example is given in Fig. 23. The shaft is cylindrical and terminates in a conical point at one end and in a very narrow, abrupt, cutting edge at the other. The whole surface is polished. The material is the same dark tufa. The class of objects illustrated in this and the two preceding cuts comprises but a small percentage of the chisel-like implements. _Spearheads (?)._--Another class of objects made of the same fine grained, slaty looking tufa is illustrated in Fig. 24. They resemble spearpoints, yet may have been devoted to a wholly different use. They are long, leaf-like flakes, triangular in section, slightly worked down by flaking, sharpened by grinding at the point, and slightly notched at the top, perhaps for hafting. _Arrowpoints._--The unique character of the arrowpoints of Chiriqui is already known to archæologists. The most striking feature is the triangular section presented in nearly all cases and shown in the figures (Fig. 25). The workmanship is extremely rude. The material is generally a flinty jasper of reddish and yellowish hues. The number found is comparatively small. The specimens given are of average size. [Illustration: Fig. 25. Arrowpoints of jasper--1/1.] _Ornaments._--It would seem from a study of our collections that ornaments of stone were seldom used by the inhabitants of Chiriqui. There are a few medium sized beads of agate and one pendant of dark greenish stone rudely shaped to resemble a human head. Ornaments of gold and copper were evidently much preferred. [Footnote 8: I am indebted to Mr. J. S. Diller, of the United States Geological Survey, for the determination of the species of stone in this series of objects.] [Footnote 9: Seemann: Voy.
