second line farther back. Thus from a purely chronological stand- 

 point the group may be subdivided into these two sections. 



In relation to the topography of the site itself the group may be 

 divided into four smaller units, as follows : 



1. The main sub-group is located east of the mouth of Kratz 

 creek, between it and a small ravine about twelve hundred feet 

 distant. It is the largest section and consists of thirty-six mounds 

 of various forms. At some distance from this sub-group is the de- 

 tached conical No. 20. 



2. The second sub-group lies east of the ravine and consists of 

 five effigy mounds. 



3. The third sub-group is immediately west of the creek and 

 consists of four mounds. 



4. The fourth sub-group, consisting of six conical mounds, is 

 situated a considerable distance to the west of the creek and imme- 

 diately along the bluff at the lake shore. 



In each of these sub-groups the mounds appear to be arranged 

 in a definite interrelation. As above mentioned, those of the main 

 sub-group are disposed in straight lines, each line bearing almost 

 directly on the large conical mound, which occupies the dominating 

 position on Kratz Point itself. 



The conical mounds in sub-group No. 1 are distributed chiefly in 

 lines of three, each set being relatively close together 7 . From con- 

 ditions observed in other groups as well as in this one it appears 

 that these may be but outlines of unfinished linear or effigy mounds, 

 which would have been completed by filling in the spaces between 

 them. 



FORMS OF MOUNDS 



In the Kratz Creek group, there are, as has already been men- 

 tioned, mounds of three general forms : conical, linear, and effigy. 

 The conical mounds vary according to construction and use, rather 

 than in form. 



The linear mounds are relatively few and unimportant, but we 

 may recognize the simple linear and the conical-ended linear types. 

 The latter is probably, as above suggested, a composite mound, 

 produced by filling in the space between two or more conicals 

 placed in a line. 



7 Dr. Cyrus Thomas, says: "the custom of placing the small tumuli in lines connected 

 and disconnected to form the long wall-like mounds seems to have been peculiar to the 

 builders of the effigies." — Mound Explorations, Ann. Rept., Bur. Amer. Ethn. XII, p. 709.
