 Technique : Use chipping only. 



Depth : 0.5-1.0 feet ; 1.5-2.0 feet below surface datum, squares CI and Dl, 

 respectively. 



V. Hammerstones. 



A. Irregular stones with one or more pounded or pecked edges (sam- 



ple: 9). Plates 25, d; 26, b. 



Range of length : 68.0-117.0 mm. ; mean, 86.4 mm. 

 Range of width : 48.5-88.5 mm. ; mean, 73.0 mm.
