Its length is 17^ inches, width 2i, and its thickness f inch. It main- 

 tains the same high standard of flint chipping as shown in most of the 

 other specimens. Its art work is well shown in the figure. 



Fig. 8!) represents an obsidian blade of large size, whicli, for want of 

 a better name, has been called a sword. Its length is 15 inches, width 

 2|, and thickness f inch, and is from a mound in 

 Oregon. It is an example of fine and delicate 

 chipping, which does credit to its maker as an 

 artist of the first-class. 



Fig. 00 is a beautiful specimen of rose quartzite. 

 Its fine grain alone rendered its manufacture pos- 

 sible. Quartzite is a refractory material, and it 

 would'have been a testimonial to the ability of the 

 artist had he made an implement, without re- 

 gard to its elegance or symmetry. However, he 

 has succeeded admirably in these points, for the 

 implement is nearly perfect in both regards. The 

 flakes by which it was reduced were extremely 

 :i I small, and the work proceeded little by little. 

 ^ I Tlie artist must have used the greatest care. No 

 I --■ owner of this beautiful specimen would risk a 

 ^ § ^ single blow upon it such as must have been 

 J I y, given a hundred or more times in the course of 

 < ^ i its manufacture. 



I s Figs. 91 and 92 are other specimens of flint 



^ ^ chipping, maintaining the standard for excel- 



" lence in this art. The former is from Groveport, 



Ohio, and was collected by Mr. W. E. Limpert. 



The latter is also from Ohio, collected by Prof. 



W. K. Moorehead. 



Curious forms. — Fig. 93, a, i, c, r?, represent four 

 arrowheads, introduced because of peculiarities 

 in the fineness of their flint chipping. Fig. 93« is 

 one of gray lustrous flint, approaching chalced- 

 ony. It belongs to Division IV, Peculiar forms, 

 Class H, Asymmetric. This specimen, as is the 

 next, is extremely thin, neither of them being much 

 more than one-eighth of an inch in thickness. It 

 comes from Santa Barbara, California, and is one 

 of four collected by Prof. David S. Jordan. Fig. 93&, also from Cali- 

 fornia, is of rock crystal and is the thinnest specimen of its kind in 

 the Museum. The chips or flakes broken from these two specimens 

 have been extremely fine and thin, leaving the edges and points smooth 

 and even, while keen and sharp. Fig. 93c, also asymmetric, is of gray 

 flint, and from Chicago. Its finder was Mr. Carl Dilg, and he has 

 pamed this specimen the "Eiverside arrow." Fi^. 93<? is presented
