Ringgold County. 



Jordan, ^° in an unsatisfactory article, reports a copper cup 

 found in 1S72 by Warner Ruby at Plum Creek, in Knowlton 

 Township; the specimen is now lost. A number of mounds are 



reported in the neighborhood. "Knowlton Mound" is 



described as 500 feet long, 130 feet wide, and 15 feet high; it is 

 said to be serpentine on one side; near the centre black loam 

 nearly 6 feet deep is underlaid by a coarse yellow sand. A skel- 

 eton was removed from here some years ago. The question of 



the entirely artificial character of this mound is raised. A 



stone dam, the stones being regularly laid, causing a "ripple," is 

 mentioned; it might well be natural (?). 



Sac County. 



Negus '°+ mentions elliptical and circular mounds which yielded 

 no returns to the investigator near Sac City. White "93 examined 

 mounds on the "second bottom" well above the reach of river 

 floods. Eight mounds with no regular arrangement extend north- 

 east and south-west; two of them are oval and six are circular; 

 they vary from 50 feet to 96 feet in diameter, and from 2^^ to 

 3 feet high. No relics were found. 



Scott County. 



Pleasanf Valley. — Ahrman 37 described a curious relic found 

 by him in digging a post-hole on an old village site, of material 

 resembling yellow clay, but hard as stone. Very smoothly carved 

 though rude and incomplete human form; 6 inches long; face 

 distinctly carved, forehead flat, hands resting on chest, lower 



limbs not carved out. Near the mouth of Duck Creek was 



a mound with about fifteen interments. Tiffany '"^ found two 

 lower jaws and the molar tooth of a bison. 



The same explorer opened two mounds at Gilbert; one yielded 

 an arrow-head, the other an arrow-head and flint chips. "^s 



East Davenport. — Churchill 31 reports a group of three mounds 

 on the edge of the bluff overlooking Camp McClellan; three 

 hundred yards from the southern line and thirty yards west of 

 the eastern boundary of the Russell estate in Davenport Town- 

 ship. The mounds are in a north-east and south-west line; they 

 are from thirteen to eighteen yards apart. The eastern one is 

 15 yards in diameter and 3 feet high; the central and western
