heads, from a broken one of which it is supposed they have been made,

PERFORATORS. 



They may have served to drill the harder substances, but also softer 

 materials, as wood, hides, bone, etc. But slight traces of usage are

 certain, and they may have had another origin or purpose. Old Indians 

 have declared them to have been charms or fetiches.
