THE ST. JOHN'S RIVER, FLORIDA. 



97 



Three feet three inches— Brown sand with a certain intermingling of shell 

 containing skeletons. 



One foot — Layer, black in color, river mud and sand intermingled, with vir- 

 tually no shell. The river mud was not a deposit, being above high water mark 

 and was evidently brought to start the burial mound, probably from the strip of 

 black loam connecting the two mounds. On the upper surface of this layer were a 

 certain number of burials, or rather bodies placed upon it had sunk in. There 

 were no bones in the lower portion of the layer. 



Two feet — Shell, crushed and whole, with a certain percentage of sandy loam, 

 the regular debris of the shell-heap. No human remains. 



Two feet — Shell, crushed and whole, same as layer above in composition, but 

 percolation of water had rendered the mass almost a solid conglomerate. In this 

 layer were found four or five human bones. 



Two feet — Under water ; crushed shell and sand)- loam ; plain potter}-. 



HUMAN' REMAINS. 



Beneath a summit plateau 35. feet in diameter were the greater number of skele- 

 tons, all in anatomical order though in various forms of flexion. Beginning at 6 

 inches from the surface, skeletons lay in a matted mass intertwisted above and below 

 each other until at places it was impossible to distinguish bones belonging to one 

 skeleton from those surrounding it (Fig. 111).
