outlines similar to a turtle back. As a whole they resemble very closely 

 the designs on pottery, particularly those reported from the Cahokia 

 group of mounds in Illinois, across the Mississippi river from St. Louis. 

 There may have been a relationship between these people who lived in 

 the same river valley and made use of similar designs. The emblems 

 on the pottery are understood to have had a mythical meaning", and 

 these ridges are apparently of a ceremonial nature. 



Referring again to the earth embankments in Indiana which form 

 a part of the chain of earthworks stretching along the south side of 

 the great lakes, the group at Anderson was described in the Geological 

 report of Indiana for the year of 1878; and again in 1892 by F. A. 

 Walker of Anderson, who read a paper at the annual meeting of the 

 Indiana Academy of Science of that year, which was published in the 

 Academy Proceedings, but without a copy of the photographs which

had been made. He had a survey made and described the group as con- 

 sisting of seven structures of circular and oblong outline, the largest 

 one being 360 feet in diameter, 1,131 feet in circumference, covering 

 two and one-third acres. The maximum height of embankment is 

 given as over 9 feet and accompanied by an interior ditch of about 

 12 feet maximum depth, and having an opening or gateway of 30 feet 

 between ends of embankment. Mr. Walker took great pains to secure 

 photographs of this embankment (fig. 5), and we take pleasure, after 

 a thirty years interval, of seeing them again presented. 



Another embankment, second in importance in Indiana, is at Straw- 

 town in Hamilton county, northeast of Noblesville. We say second in 

 importance, for while it is a single embankment instead of one of a 

 group, yet at the same time is one of the noted exceptions in the way 

 of construction, being one of the few having the ditch outside of the
