on the ridge separating the Mississippi and Turkey Rivers. The 

 ridge is never more than a mile in width and is usually narrow ; 

 it rises two hundred to three hundred feet above the river level. 

 Mounds, extending in a line toward the north-west for about six 

 miles, occur upon it ; they number more than forty, and comprise 

 simple conical mounds, embankments, and efifigies. This group 

 was the one upon which McGee made his special metrological study. 

 Hermann 2" reports a fine double-grooved stone axe, 10 or 12 

 inches long, from a mound near Catfish Creek, and a nearly 

 transparent quartz spear-head 7 to 8 inches long. 



Emmett County. 



Aldrich ' mentions a line of thirteen large mounds, extending 

 north and south, upon a high river terrace ; they are from i)4 to 

 6 feet in height; no exact location is assigned. 



Floyd County. 



Webster has pursued studies here with much care, and reports 

 the results in several important papers. 



Near Charles City '^7 is a large and very interesting group of 



thirty-one mounds. They lie, 

 with one exception, near the 

 centre of Sec. 26, Twp. 96, R. 

 16 W., about two miles north- 

 west of Charles City (the one 

 exception is near the centre of 

 p3 S.-W. r^ Sec. 23). Twenty- 

 eight of them are in a nearly 

 straight line running 20° W. of 

 N., on the summit of a low, 

 broad ridge. The topography is 

 shown by the diagram. (Fig. 8.)
