 uses, brought from the villa};:es and utilized in the ([uarries. A major- 

 ity arc of tlie first of these classes. They arc, as a rule, ([uitc rude, 

 and were derived from <|uartz veins and bowlder beds in the vicinity 

 of the quarry. Specimens collected apj)roach as nearly a i)aleolithic 

 type as any tools found in the Potomac region. Nothing more prinu- 

 tive is ])ossible. The hills and slo[)es in the vicinity abound iu out- 

 croi)s of veiii quartz, which breaks up into angular fragments. These 

 are now so plentiful on the neighboring lields as to burden agriculture. 

 Such angular fragments were gathered for use in the quarries. Some 

 were already well adapted to use, while others wei-e slightly trimmed, 

 to give them better points and edges. Illustrations of these tools 

 appear in figures lii and I'd.

A number of angular masses of quartz were discovered that were 

 not apparently adapted to any use and that showed no signs of having 

 been used. They may be fragments of larger masses broken iu use. 

 A few bruised cobbles were found that must have been utilized in some 

 way in the quarry work. 



It is not considered necessary to take further notice of sjiecimens 

 showing no decided evidence of design or use, or that do not by their 

 natural conformation show especial adaptation to use. The objects of 

 quartz that show evidence of shaping by i)ercussion are all of one 

 type. They are thick, angular masses, weighing a pound or more; one 

 end is brought to a short, sharp point, and the other is somewhat 

 rounded, as if to be held iu the hand or bands for striking. Of the
