In many sites the various types found are so distinctive that

 the Iroquois have occupied the site where the specimens were found. 

 Fragments of decorated pottery would of course be strengthening 

 evidence. 



The numerous forms in which arrowheads were made make anv 

 attempt to describe all varieties a lengthy and difficult task. Not only
