The complete classification of chipped implements was presented on pages 23 to 30 of this work. It is now my purpose to describe and illustrate each form or type mentioned in the classification. Therefore, we begin with types without stem, which are considered to be knives and projectile points. I have referred to figures, in the following table, in order that readers may have no difficulty in distinguishing one type from another. A. Without secondary chipping (knife flakes). (See Figs. 26 and 35.) B. With secondary chipping (rougher knives). (See Figs. 44 and 46.) 1. Pointed at one end, base straight. (See Figs. 47, 50, and 58.) 2. Pointed at one end, base convex. (See Figs. 54 and 69.) 3. Pointed at one end, base concave. (See Figs. 50 and 56.) 4. Pointed at one end, sides convex. (See Figs. 55 and 74.) 5. Pointed at one end, one side convex, one side straight. (See Figs. 52 and 53.) 6. Pointed at both ends. (See Figs. 67 and 131.) 7. Decreasing diameter towards end, ends convex. (See Figs. 61 and 72.) 8. More or less oval, or circular. (See Figs. 72 and 75.) Before I take up the large class cited above, I wish to state that in a classification of flint implements much depends upon one’s point of view. Some observers may classify according to whether the stem contracts or expands. Others might adopt yet another form of classification. There are some specimens that on classification because of variation in the stem might be included along with more simple forms, yet there are not a few which the Indian apparently specialized, which he purposely made different from the others. These doubtless represent individual fancy and should not be entered as types. Many specimens not included by the committee in its classification seem to me to be types, and I have therefore added such in subdivisions. These, I am firmly convinced, are as representative type specimens as are the others that have been entered. Along with these, illustrations of certain beautiful flint implements are submitted herewith. [Illustration: FIG. 63. (S. 1–4.) Knives of various forms and material, from Maine sites.
