plement consists of two parts — a large block of stone with a concave 

 surface, upon which the maize is placed, and a carefully-dressed but 

 coarse-grained slab of stone for grinding. This slab is generally from 

 8 to 12 inches long by 3 to 6 wide, and from 1 to 2 inches thick. The 

 specimen illustrated is made of black cellular basalt, and was found 

 ■with many others at the ruined pueblo near Ojo Galiente, N. Mex. 

 (Plate X). 



Figure 5 is a very much worn specimen of stone axe, which was found 

 at an ancient ruin near Abiquiu, IST. Mex. It is made of light-colored 

 chloritic schist, and measures 2 inches in width by 3 in length. 



Figures 6 and Qa are specimens of ear-ornaments, such as are found in 

 connection with very many of theruihs of Southern Colorado. These are 

 made of fine-grained gray slate, only moderately well polished, and 

 measure an inch and a quarter in length. 



Figure 7 represents a marine shell of the genus Olivella, obtained prob- 

 ably from the Pacific coast. Large numbers of this and allied sheila 

 are found about these ruins. They are generally pierced, and were 

 doubtless used as beads. 



Figure 8 represents a small carved figure found on the Eio Mancos. It 

 is made of hard gray slate. Its use or meaning cannot be determined. 

 'm Figure 9 represents a stone ring f of an inch in diameter, and probably 

 intended for the finger. It is made of hard gray slate ; is shaped like 

 the usual plain gold ring, and is quite symmetrical. 



Figure 10. Arrow-heads were found associated with nearly every ruin 

 examined. They present a great variety of forms ; some of the more 

 striking of these are given in the figure. The materials used in their 

 manufacture are principally the more beautiful varieties of obsidian,, 

 asper, and agate.
