In No. 13 our excavation went down to a depth of 9.24 feet be- 

 low the top of the mound or to a point 14.65 feet above mean lake 

 level. In No. 14 the excavation extended to the same gray clay 

 stratum, at 14.79 feet above mean lake level or 9.1 feet below the 

 surface of this mound. A red sandy clay layer appeared to mark the 

 bottom of both these mounds. In No. 13 this was located at 17.09 feet 

 above mean lake level or 6.7 feet below the surface of the mound 

 and 2.86 feet below the surface of the surrounding land. In No. 

 14 this bottom was at an elevation only 0.1 of a foot higher than in 

 No. 13, or 17.19 feet. This gives practically the same depth of ar- 

 tificial strata.
