The next two specimens (figs. KJO, 101), wliile liaving stems sluuil- 

 deied and not barbed, belong to ( 'lass I>, but represent a marked ditler- 

 ence froai the former specimens. Wiiile the edges of 

 the stem are straight and i»arallel. the base is convex. 

 No reason has ever been given for this peculiarity, but 

 it is a noticeable one and involves 

 another even less explainable. Why 

 the stem of an arr<)wi)oint intemled 

 Ibr insertion in a shaft should be 

 made convex instea<l of straight or 

 concave, is a matter ofbut slight im 

 ])ortan<'e and need in itself excite no 

 cnriosity; bnt all bases of stems 

 which are convex have been worn or 

 rubbed, or in some way made smooth. 

 They have not been polished or ground 

 upon the sides, but liave been o[)er 

 aled in a reverse manner against the 

 edge of the base, and have made it 

 blunt and smooth and not sharp. It would be beyond 

 the author's ])rovince to say that this is universal, for 

 no man could have had suth(ientexi)eiience to justify such astatement, 

 but in the l'. S. National JMuseum thousands of such arrowpoinls have 

 been tested and 90 per cent or more of them have been 

 found to be in this condition. IS"© 

 explanation has ever been given, nor 

 has any been suggested. It is more 

 marked in the cases of leaf-shaped 

 ill l»lements which liave been trans- 

 formed into stemmed arrowi)oints, 

 leaving the convexity of the base un- 

 changed. The points and edges seem 

 to have had no share in the operation 

 and they continue rough and sharp. 

 Fig. !()(► is of yellowish jasper, comes 

 from Lincoln County, INIississippi, and 

 is doubtless from the same jasper 

 (piarry which furnished the great 

 nnmber of jas])er beads found there 

 in a workshoj) by Mr. Keenan and de- 

 Fig. 1(>1 is the same form as the pre- 

 ceding. It is of white flint from Illinois, and is much 

 finer and more delicate than the jasper one, but it has 

 the convex base, the smoothed condition of wliich is (piite perceptible. 

 The next three figures (1G2-1G4) represent another form of base. The
