FIG. 120. (S. 1–2.) Typical Oregon projectile points. H. P. Hamilton’s collection, Two Rivers, Wisconsin. ] In order to place the evidence I have collected along these lines before readers, I would cite the finding of twenty-two axes in one room of a ruined pueblo, five miles south of Phoenix, Arizona, in 1897. These are of the variety of stone and the same workmanship. Six particular disc-pipes were found in graves at the mouth of the Wabash by Clifford Anderson, in 1898, when exploring for the founder of the Archæology Department of Phillips Academy. I would mention the effigy pipes found by Squier and Davis at Mound City, a cache of forty leaf-shaped implements, slightly different from the ordinary leaf-shaped knife of similar material and the same workmanship, found in 1896 in a mound near Coshocton, Ohio, the Hopewell discs, and the Hopewell sheet copper. [Illustration: FIG. 121. (S. 1–3.) White flint knives and arrow-heads. These are from Michigan-Wisconsin sites and illustrate the peculiar forms obtained there. The types are long and slender or short and broad and are easily recognized. H. P. Hamilton’s collection, Two Rivers, Wisconsin. ] [Illustration: FIG. 122. (S. 1–2.) These are the finest points in the Ozark region, where most of the types are crude. Materials: chert and quartz. At the bottom in the centre are shown three points almost Oregon-like in character. Attention is called to the serrated point in the middle row. Dr. W. C. Barnard’s collection, Seneca, Missouri. ] [Illustration: FIG. 123. (S. 1–1.) These points are different from Oregon points so frequently shown. Materials: opalescent and white chalcedony and mauve quartzite. These are Eastern types, but are made of Western material. Luther A. Norland’s collection, La Jara, Colorado. ] [Illustration: FIG. 124. (S. 1–2.) Common New Jersey forms. Stephen Van Rensselaer’s collection, Newark, New Jersey. ] [Illustration: FIG. 125. (S. 2–3.)
