HOLMES] DISTRIBUTION OF IMPLEMENTS 143 



1. Ou a site of (luarrylng and manufacture wbere dwelling was 

 inconvenient, as ou the bluffs of Rock creek, the work was confined 

 mainly to roughiugout leaf-shape blades, and the series of art forms 

 comprises a liuuted range, including turtlebacks and other kinds of 

 rejects, with refuse and implements of manufacture. On the quarry- 

 shop sites of Rock creek nothing exotic, nothing finished, nothing that 

 might not readily be classed as paleolithic, if shape alone were consid- 

 ered, was found in three months' work. 



2. On a site of quarrying and manufacture where dwelling was prac- 

 ticable, and where lodges were actually pitched to a limited extent, we 

 find intermingled with the rude forms some specialized implements and 

 a few tools of exotic origin, such as projectile points of rhyolite, with 

 axes and celts, as at Riggs mill, S miles northeast of Washington. 



3. On a site of manufacture and at the same time of extensive dwell- 

 ing, as at Anacostia, in the District of Columbia, where much raw 

 material was at hand, all varieties of refuse and of rude forms are 

 found; likewise well-shaiied and wholly finished specimens of fiaked 

 tools of local origin prevail. There are also all the cut, pecked, and 

 ]>olished tools, and the ceremonial stones and ornameuts common to 

 village-sites. Besides these many exotic materials in varied forms are 

 found. 



4. Ou a village-site where no raw material save small quartz pebbles 

 is found there will be a full lange of small quartz rejects and of small 

 quartz implements, with a liberal supply of finished imijlements of 

 exotic materials, averaging small. 



5. On a site remote from all sources of raw material, as on the east- 

 ern shore, the objects average small and are much varied in material 

 and style, having come far, through numerous peoples, and from many 

 sources. 



Typical illustrations of the two last-mentioned varieties of sites are 

 ditticult to find, for the reason that in all sections, even far out toward 

 the present ocean beach, there are occasional ice-borne bowlders and 

 fragments of considerable size, and these were collected by the natives 

 and used for mortars and mullers and for various flaked and battered 

 implements; and such objects destroy the entire simplicity of condi- 

 tions conceived for the sites described. 



IJISTRIRUTION BY GENESIS AND FUNCTION 



A synoptical statement is made in the accompanying i)late (Ci), 

 which exhibits many of the most striking features of the tlaked-stone 

 archeology of this province, and indicates clearly the points most 

 recjuiring attention in other regions. The stories of the origin and 

 form of the material, of manufacture, rejection, elaboration, transpor- 

 tation, storage, specialization, and use are all expressed or suggested. 

 Four materials are represented — two native and in the form of bowl- 

 ders, and two exclusively exotic and derived from mass deposits. Each 

 series indicates the course of development through which most of the
