3lWal is located on a small hill adjacent to Dix Creek, a tributary 

 of Nutbrush Creek, and covers an area about 40 feet square. Over 

 this area numerous stone chips are scattered. A careful search of the 

 area failed to produce even a single artifact. 



The two sites in Vance County had all the earmarks of recognizable 

 workshops, since chippage practically covered the surface of the 

 sites and large chunks of broken stones lay about the area. Here, 

 again, we failed to recover a single artifact. 



SUMMAKY OF POTTERY TYPES 



A summation of the pottery types from the various sites within 

 the basin is presented in tabular and graphic forms, tables 18 through 

 21. Forty-one thousand eight hundred and forty-four sherds consti- 

 tute the study series. Of this number 11,969 have been assigned to 

 the Hyco Series and the remainder to the Clarksville Series. 



By glancing over the tables one will see that there is greater elabora- 

 tion of exterior surface treatments in the Clarksville Series, a trait 

 which is to be expected since it has a greater time-space relationship. 



The basic difference between the two series lies in the fineness of 

 the particles and the amount of sand added to the clay to form the 

 paste, as well as in the methods of firing the vessels. In the Hyco 

 Series the sand particles are much finer and the amount used consti- 

 tutes less than 45 percent of the total contents; while in the Clarks- 

 ville Series the particles are much larger and the amount ranges 

 around 55 percent, or greater. All Hyco vessels were fired under an 

 oxidizing atmosphere which is not only more penetrating but to a 

 certain extent is controllable, bringing about more uniform color 

 standard with fewer incidents of fire clouds. In the Clarksville Series 

 an oxido-reducing atmospheric condition was utilized which is not 

 only less penetrating but does not produce uniform results in the 

 color range, hence the mottled color effect ranging from a buff-brown, 

 a dark gray, or a black in wall coloration and with a darkened core. 

 Fire clouds are nearly always present and the hardness of the ware is 

 much lower than that found in the Hyco Series. 



Using textile-impressed as a controllable standard in the pottery- 

 bearing sites and graphing the other w^ares, each in its relative position 

 according to its percentage range, a standard chart of pottery trends 

 over the existing occupational span of the reservoir area is then estab- 

 lished (fig. 65). Textile impressed had a steady growth from the 

 beginning to the end, while fabric-marked was at its height at the 

 beginning of pottery making and hastily decreased only to have a 

 slight renaissance which gradually died away near the end of the 

 occupation of the reservoir basin. The heavier fluctuations in the 

 fabric-marked graph were repeated on a smaller scale and over a 

 longer range.
