ridge north. Group 8 comprises twelve mounds on the crest of 

 a divide passing around the head of a ravine ; the Hne follows 

 the curve of the divide. 



Louisa County. 



Gass ^3 states that groups of mounds are thickly scattered 

 along the bluffs overlooking the Mississippi Bottom for many 

 miles. Quite extensive investigations have been carried on in 

 Grandview Township by Gass and Blumer. ^3 The descriptions 

 lack definiteness ; a carefully made map of the district is desirable. 



Sec. II (Wagner Farm). Gass 7^ locates here a group of thirty- 

 six mounds ; the largest are 6 feet high. Many had been pre- 

 viously opened with no results ; he opened seven. 



{a). At 6 feet down an ash-bed was found, with fragments of 

 pottery and two implements of igneous rock. 



{J)). The largest of the group; at 6 feet down, on the east 

 side, was a large piece of limestone with a few pieces of pottery 

 upon it, with an arrow-head, and a clay figure of a human head 

 an inch in diameter and showing action of fire ; on the west side 

 was a piece of limestone with a small stone axe and a discoidal 

 stone near it. In the other five nothing was found. 



Sec. I J. Gass 71 explored two mounds in this section; they 

 were about 4 feet in height. 



(a). Bed of ashes containing bits of potteryand flints was found. 



{b). Yielded potsherds. 



A group of ten or more mounds occurs in the north-east cor- 

 ner of the north-west quarter of the section, on Viblen's Farm. 

 Gass ^3 explored four of these with some result : 



{a). Thirty feet in diameter; 3 feet high. At 3 feet down 

 some bones were found. 



(^b). Fifteen feet distant from {a); 30 feet in diameter; 2j4, 

 feet high. At 2^ feet down were one arm-bone and one leg- 

 bone. 



(c). Oval; 15 feet by 30 feet. At 3 feet down were two 

 skeletons in clay. 



(d^. Twenty-five feet in diameter; 2)^ feet high. A few 

 decayed bones were found. 



Kallenberger had opened six others of the group without find- 

 ing anything of interest.
