FIG. 9. PLAIN FLAKES. 



\ Full Size. 



County Antrim has yielded a large number of simple flakes, 

 perfect and uniform in shape and character, although struck off 

 by a single blow. Such flakes generally assume the typical form 

 described in the text, and illustrated by Fig. 9. The skilled 

 worker formed a central ridge by striking off a flake from each 

 side, and then by a dexterous blow behind the ridge, the flake 

 is struck off, well shaped, sharp, and clean on the edges. 



FIG. IO. — FLAKES WITH SECONDARY CHIPPING. 



\ Full Size. 



The great bulk of the flakes are more or less chipped into 

 form by a process of secondary chipping, whic h is used to enable 

 the fabricator to adapt the flake to its intended purpose. 

 Obviously the badly-formed flake required the most chipping, but 

 many of the otherwise well -formed flakes require to be mounted 

 for use, and the preparation for this required a tang or handle 

 to be formed at the thick end, next the bulb of percussion. 

 This tang is common among the chipped flakes, and is formed 

 by chipping away a portion of the blade at each side, as shown 

 by the illustration.
