98 CERTAIN SAND MOUNDS OF 



Interments did not continue throughout the mound, the sides of which had 

 been extended and raised to protect the burials from the river at high water. 



With a female skeleton, somewhat over 4 feet from the surface was a number of 

 fragments of human bones charred and calcined, including portions of the upper 

 maxillary, of the femur, a metacarpal bone, one of the phalanges and other frag- 

 ments unidentified. As cremation previous to interment was not practised in the 

 case of any burials met with in the mound, this case can hardly be considered as be- 

 longing to that form. The skeleton in immediate association was unaffected by fire. 



To illustrate one of various forms of flexion we quote from our field notes : 

 " Skeleton C. lay 4 feet from the surface in a dorsal position with head turned to 

 one side, arms parallel with body, forearms flexed upward with bones parallel with 

 humeri, thighs flexed over abdomen, legs flexed on thighs, making tibiae parallel 

 with femurs ; vertebrae and ribs beneath with pelvis in proper position. To a casual 

 observer this skeleton would have seemed to be a bunched burial as the bones of 

 the extremities la}' side by side." 



Tibice [first visit) . — During our first visit 66 tibia 1 gave an average lateral in- 

 dex of 60-2. 



Humeri [first visit) — Seventy-six humeri from all parts of the mound showed 

 40 perforations, a percentage of 52 - 6. Of these 23, coming from a depth of 2 - 5 

 feet from the surface or less, showed 13 perforations, or 56.5 per cent. 



Fifty-three humeri, believed to be undoubtedly original burials, contained 27 

 perforations, a percentage of 50'9. 



Crania. — During our second investigation two calvarias were saved, one super- 

 ficially and one of especial interest being from the very base of the mound. As 

 previously stated, all crania will be described by Dr. Harrison Allen in Part II of 

 this report. 



Humeri [second visit). — Upon our second visit (February, 1893), if possible 

 more care was taken than before in respect to determination of the olecranon per- 

 foration. Fossa? were cleared by the aid of water. A magnifying glass was called 

 into requisition, and three perforations of doubtful origin were discarded from the 

 list. All perforated humeri may be seen at the Museum of the Academy. 



Of 41 humeri possibly intrusive 1 20 were perforated, giving a percentage of 

 48-8. The perforations were distributed as to sex as follows : Male, 6 ; female, 6 ; 

 uncertain, 8. 



Of 23 humeri from original burials, 11 showed perforation, a percentage of 

 47-8 ; the perforated humeri being male, 7 ; female. 3; uncertain. 1. 



1 Among these humeri are included many doubtless from original burials, since, as we shall see, no 

 certainly intrusive interment was found at a depth greater than 18 inches, while all bones within 2-5 feet 

 from the surface are classed as possibly intrusive.
