Annual report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution . SPECIALIZED QUARTZITE BLADES, PROBABLY IN THE MAIN PROJECTILE lACTUAL SIZEI FROM POTOMAC VILLAGE- Bureau of ethnolog FIFTEENTH ANNUAL REPORT PL. XXXVII. SPECIALIZED QUARTZITE BLADES, PROBABLY IN THE MAIN ARROWPOINTS, FROM POTOMAC VILLAGE-SITES (ACTUAL SIZE) HOLMEsl PROCESSES OF FLAKING 61 into implements may have beeu selected for trausportatioii, but noevidence of this is procurable. The course of procedure just described I have investigated in themost careful manner, and by experiment have followed every step ofthe i)rocess, and have achieved almost every result. I have found thatin reaching one final form I have left many failures by the way, andthat these failures duplicate, and in proper pioportions, all the formsfound on the quarry sites. I was unfortunately prevented from carry-ing out these experiments as fully as desirable by j)ermanently disablingray left arm in attempting to Hake a bowlder of very large size. I further find by these experiments—and the conclusion is a mostimportant one—that every implement resembling the final form heredescribed, and every blade-shaped projectile point made from a bowlderor similar bit
