2 b. Beveled points. Of these only a small number of examples have been recovered. They are distinguished from the most frequent flat, stemmed form by a distinct bevel of generally uniform width which extends along the edges on both faces of the blade. Sometimes this bevel is nearly one half inch in breadth. The shape of the blade varies considerably. The known specimens range from two and a half to five inches in size. Examples are to be seen in the Field Museum, H. P. Hamilton, and other collections.
2 c. Eyed points. The base of the stem in this rare form is provided with an eye, opening outward and probably intended for the reception of a rivet. Otherwise these points do not differ from the flat, stemmed types. Only a very small number of specimens have been found.
2 d. Notched points. These bear a close resemblance to a numerous class of flint arrow- and spear-points, after which they are probably patterned. No two of them are exactly alike. They differ from each other in the shape of the blade and shape and position of the notch. A few are traversed by a median ridge. Some have indented bases. They vary in size from less than two and up to six inches in length. Such points are of infrequent occurrence. Specimens are in existence in the Milwaukee Public Museum, Field Museum, Logan Museum, and other collections.
2 e. Toothed points. These are rather remarkable and interesting implements, and are distinguished from all others by the peculiar angular toothing or serration of the edges of the stem, the purpose of which is evidently to facilitate the fastening of the point to the wooden shaft or handle, into which it was inserted, by means of sinews or strips of hide. A greater solidity of attachment was thus secured. The number of opposite notches on the stem varies in different examples, from two to as many as six or seven. The usual number appears to be two or three. Most examples of this type are long and narrow. A few, however, are short and broad, and elliptical in outline. The largest known example of this form is about nine and a half inches and the smallest about two inches in length. The average size appears to be about three and a half inches. In many specimens a central ridge or elevation extends along either side from extremity to extremity, or only from the base of the stem to the point of the blade. (Fig. 599.)
