nearly gone, but potsherds, flint chips and flint implements are 

 picked up within its area; the pottery paste is of river mud 

 mixed with pounded fresh-water shells (Shaw '57). Probably the 

 following description by Stevenson "38 refers to this same locality. 

 He describes it as in the vicinity of Toolesboro : 



"A raised circular earthwork; it resembles a horseshoe. The 

 open part abuts upon the edge of the bluff among a group of 

 mounds. The surface and soil are covered or supplied with an 

 immense quantity of broken pottery and flint chips and imjjle- 

 ments. These last are nearly all small, uniform in shape and 

 size; they are like a half-cone in form and are \% inches long, 

 ^-inch wide at broadest part, ^-inch thick at thickest " Ap- 

 parently "the circular enclosure of lo acres" mentioned by 

 Alexander. ^ 



This work is also described by Toole '79 and by the Davenport 

 party. The latter give considerable detail, thus : One-fourth 

 mile north-west of these mounds was an earthwork enclosing some 

 15 or 2o acres: octagonal in form, the sides are curved and the 

 inner edge is circular; the embankment, once about 2 feet high, 

 is now nearly obliterated ; the area is strewn with flint chips and 

 potsherds; in a few hours fifty or more flint implements were 

 found, among them a few arrow-heads ; most, however, were well 

 worked, plano-convex objects, from i to 2 inches long, about half 

 as wide and ^-inch thick, rounded at each end but with one 

 more tapering than the other, even bluntly pointed at times; (the 

 form is somewhat like a flat-iron without a handle). The pottery 

 from this site is unlike that from the mounds; it is grayer, and 

 composed of mixed earth and .shell; broken handles are common. 



Remains somewhat like stone walls also occur. '38 



Three miles south of Toolesboro, near Iowa River, are outlines of 

 three ancient structures in which stones were used. The material 

 was granite bowlders from the river below. There were five or 

 six such structures in a line, nearly parallel to the river bank, 

 about twenty feet from it, about 6 feet square and some 20 feet 

 apart. Few stones are left ; the best preserved showed evidences 

 of fire upon being opened; the bottom was rather dark and 

 burned almost to brick for 2 inches in depth ; a double row of 

 slight depressions, less than two feet deep, alternate with these
