This quarry was the largest in that portion of the United States. 

 The investigations show it to have been used during the later prehis- 

 toric ages and that it was the center of an extensive commerce. The 

 peculiar appearance, variegated color, brilliancy, etc., of its products 

 enabled their nngration or commerce in prehistoric times to be traced 

 and the objects to be recognized whenever found. 



There were many mines and quarries in the territory now the United 

 States which furnished material for aboriginal stone implements. 

 Some of them may have continued to be used by the savages in more 

 modern times, but most of them are entirely prehistoric. It is needless 

 to describe them, but the reports of their discoveries have been col- 

 lected and are published for the convenience of students. They form 

 part of Appendix A (p. 961). 



CACHES. 



The only method possible for the savage to preserve property left 

 behind him on his departure was to secrete it, and this was usually 

 accomplished by burying it. This custom prevailed among the pre- 

 historic peoples of Europe as well as of America. By what name the 

 savage called this deposit is not known, or if known is not used. In 

 English it has been called deposit, hoard, etc., but the most popular 

 word is the French one of cache. It signities concealment or hiding, 

 and was first employed in America by the early French Canadians, the 

 coureurs du bois, being applied to a concealed or deposited hoard or 

 supply, usually of provisions, in which sense it is used in many of the 

 early histories and travels in Canada and the lake regions. 



In forming a cache or hoard of implements, no general or uniform 

 method was followed, but they have been so deposited as to show 

 intentional placement. Usually they are in a circle, and may be laid 

 fiat or on edge, sometimes on end. 



Keports of caches have been made by their discoverers, and for the 

 convenience of the student these have been collected and are published 

 in Api)endix B (p 97U). 



Implements of the leaf-shaped class have been found en cache, or
