At the last meeting of the Philadelphia
Academy Of Sciences, Mr. John Ford described group
a. eight burial mounds opened by him near Coups Creek.
Jiacoupin County, III. Each Of the graves was lined
with stone slabs and after the bodies were placed Do
lositou Within earth had been packed around them so
rs to the inclOsure. All the skeletons found IN these
graves faced the east In OF the graves four sRce
tons were found seated two pairs the knees Of one
rair pressing against the backs Of the other The arms
were crossed In the right hand of each Individual thus
inferred a large marine shell (Bucc,aiaa PcrrerS'D1,
Inn) had been placed that the small end of the shell
rested in the hand and the large end in the hollow above
the left hip. Within each shell what appeared TO be the
bones OF a child found, whose skull had ocCh
crushed before burial the skull prorudinc beyond the
aperture the shell IL is thought that these infants
