COLUMBIAN HISTORICAL EXPOSITION AT MADRID. 



obsidian and jasper, in the Terry collection of the New York Museum 

 of Natural History, are fully equal to them, as are also the two knives 

 of hornestone resembling form ft, fig. 20, found by W. K. Moorehead in 

 Ohio mounds, (see Primitive Man in Ohio). 



It is interesting to see one of these knives (resembling at one end 

 20, perhaps,) brandished in the hand of a priest in the Codex 



Fig. 21. 



TRACINGS FROM ORIGINAL DRAWINGS MADE BY THE ANCIENT INHABITANTS OF YUCATAN AND TENNESSEE, 

 SHOWING HOW LARGE ECCENTRIC FORMS OF CHIPPED STONE WERE USED. 



(a and 6) Codex Troano ( Yu 



i) ; (c) engraved shell gorget, MacMahon Mound, Tennessee 



Troano (fig. 21 a), another similarly grasped (fig. 21 6), and to compare 

 them with the knife resembling figure 20 a in the hand of one of the 

 figures upon the famous carved shell gorget from the Macmahon 

 Mound, Tennessee (see fig. 21 c, Thruston, p. 338). 



CHIPPED GROOVED AXES AND IRREGULAR FORMS. 



We find in the Hemenway collection a mounted chipped ax (fig. 23) 

 from the Moqui Indians of Arizona, and another in the Nordenskjold 

 expedition collection (Swedish exhibit) from the Zuiiis. The National 

 Museum exhibits a series from several sites in the United States, of 

 various materials, and the University of Pennsylvania two from the 

 Delaware Valley 5 and it may not be going too far to connect these 

 forms with some of the rudely chipped slate specimens (fig. 22, a and &) 

 from Costa Eica and other localities. 



CHIPPED CELTS, ADZES, AND SCRAPERS. 



Some of these (see fig. 24 ), often doubtless only blocked out forms 

 to be afterwards polished into shape are exhibited in the cases of Costa 

 Eica, United States, and Nicaragua (Peru, Cuba, Guatemala, Ecuador, 

 Mexico, British Columbia, and Alaska, exhibit only the polished pat 

 tern), and are not to be distinguished in form from the specimens from 

 England, France, Italy, Spain, and the Lake Dwellings, where they are 

 often found socketed in deer-horn handles (fig. 24 (c) ).
