moraine, is the region about the Menominee river in the 

 northeast portion of the state. At the time that paper was 

 written the Kohlsville stone had not been given an exam- 

 ination, but the writer has since had an opportunity to 

 examine it and has found it to very closely resemble the 

 other large diamonds found at Eagle and Oregon, so that 

 the theory that the diamonds found in the kettle moraine 

 have a common source, is thereby supported.

It seems at first a little surprising that the Eagle and 

 Kohlsville diamonds should not have been earlier identified, 

 but it must be borne in mind that simple as is the 

 determination of this gem, it is rare to find anyone not a 

 professional mineralogist who would think to apply the
