20 PROCEEDINGS OF THE NATIONAL MUSEUM vol.73 



The lack of chipped obsidian blades and knives has been mentioned. 

 There were no horse trappings, such as braided ropes of horsehair, 

 nor do any rock sculptures of the figure of the horse appear anywhere 

 except at Rock Island among the petroglyphs pecked into the crudely 

 columnar basaltic cliffs of the Columbia River north of Wahluke, 

 either at Vantage Ferry, Sentinel Bluffs, or Beverly. No objects 

 made from horn of the bison were exhumed, nor were there any other 

 indications of the use of buffalo products. There were no hafted and 

 grooved axes; neither was there any indication in the burials that 

 the Plains type of costume was used. Petroglyphs of the human 

 figure on the west escarpment of the Columbia at Vantage Ferry, 

 also at Beverly and at Sentinel Bluffs, appear to indicate, on the con- 

 trary, the use of some sort of a feathered headdress. That the prac- 

 tice of wearing feathered headdresses was an early one is further 

 strengthened by the etching of a costumed human figure on a wooden 

 comb which was exhumed at Vantage Ferry, and by a carving on 

 wood of a fully costumed human figurine showing use of a feather 

 headdress, exhumed at Tampico.
