in an occupation area. The single included flake (see below) re- 

 inforces this possibility. It further seems probable, since no old soil 

 surface is present, that an area, at least coextensive with the current 

 superstructure, was stripped of sod prior to mound construction. 

 The superstructural stratum B, since it is not sharply demarcated 

 from A, was probably formed at the same time. It is of a homo- 

 geneous matrix containing no occupation debris. 



ARTIFACTS 



A single flake (13JH4-1), evidencing no purposeful retouching, 

 is the sole artifact. 



Depth: 2.4 feet in square 2 (stratum A). 



ANALYSIS 



Mound No. 4 can be summarized as follows : 



Conical form 



Probable removal of turf prior to construction 



Body of mound formed in an abbreviated laminar fashion 



Structural materials may derive, in part, from an occupation area 



Possible limestone inclusions 



No burial is present 



The structure of mound No. 4 differs from that of 13JII3 only in 

 that it was formed in two units. The presence of conical mounds of 

 a primary-secondary or laminated structure has been noted in Jo 

 Daviess Co., 111. (Bennett, 1945, table 2, p. 97). It is not a frequent 

 feature in that area, and the pattern of construction is markedly 

 more complex than in the current example. Mounds are also largely 

 unstratified in the Effigy Mound Culture of Wisconsin (Eowe, 1956, 

 p. 72). 



Removal of topsoil or turf prior to mound construction is a widely 

 distributed trait in northwestern Illinois (Bennett, 1945, table 1, 

 p. 96; table 2, p. 98), and is not infrequent in Wisconsin (Rowe, 

 1956). In total, however, the traits present in mound No. 4 are non- 

 distinctive in terms of the more complex patterns present to the 

 northeast. 



MOUND NO. 6 



The diameter of mound No. 6 is 25 feet and the height is 2.5 feet 

 (fig. 14). Excavation procedure was basically similar to that em- 

 ployed in the testing of mound No. 4 (above). The initial excava- 

 tion, however, was much expanded in order to sample a more ex- 

 tensive portion of the structure (pi. 19, a) .
