Johnson County — Continued. 



Near the mill one-half mile north of Iowa City are two series 

 of lines of circular mounds upon the top of a high, narrow ridge; 

 the mounds are 20 to 21 feet in diameter and 30 feet apart; in 

 their arrangement they follow the form of the ridge. ^^9 



One-half to three-fourths of a mile north-west of the mill 

 there are from fourteen to sixteen long and circular mounds; 

 many have been plowed away. ^^9 



White '93 mentions mounds along the bluffs of the Iowa River 

 between Iowa City and Columbus Junction (Louisa County) ; he 

 particularly mentions a numerous group just below the mouth of 

 the English River; these may be in Washington County — not 

 in Johnson. 



Keokuk County. 



Bassett ^^~ describes stone and copper implements from Keo- 

 kuk County. Morgan '^i- ^lo reports the finding of pottery 



at a depth of 20 inches in a mound near Richland; the mound 

 was 250 feet in base circumference and 2 feet high; some of the 

 vessels were very large and shaped like "a common dinner-pot;" 

 around the rim was, frequently, a narrow band divided into tri- 

 angular spaces filled with parallel lines running vertically and 

 horizontally in alternate triangles. These largest vessels are said 

 to have been 9 feet in circumference, and to have contained 

 human bones. 



Lee County. 



Myers 9^ reports mounds near Wevcr and Jollyville ; one near 

 the latter place is on the property of John Junge; one in Lay- 

 ton's meadow had a diameter of 32 feet, a length of 50 feet, 



and a height of 7 to 9 feet. The same author reports on 



the Myers Farm, Green Bay Township, some fifteen or twenty 

 mounds; there are others on adjoining farms. All are oval, 12 

 to 30 feet in diameter, and 2 to 7 feet high ; some yielded flint, 

 pottery, and human or animal bones; some of the human bones 

 were charred or burned. In one mound thirty-two skele- 

 tons were found, sitting, in limestone vaults made by setting slabs 

 on edge and covering them over with other slabs ; some of these 

 slabs weigh 250 to 275 pounds; no limestone beds are nearer 

 than one and one-half miles.
