CERTAIN RIVER MOUNDS OF DUVAL COUNTY, FLORIDA. 469 



pint capacity, is of fairly good material carefully smoothed. Its height is 3.6 

 inches; its maximum diameter, 3.9 inches, while the aperture, from which the rim 

 turns out slightly, has a diameter of 2.9 inches. There are two perforations for 

 suspension. 



The smaller vessel, with a height of 3.3 inches, a maximum diameter of 3.3 

 inches, and a diameter at opening of 2.6 inches, has a perforation at either side for 

 suspension. The rim is slightly scalloped and to a small extent everted. The 

 body of the bowl is decorated as shown in Plate LXXI, Fig. 3. The material is of 

 good quality. 



In the southern margin of the mound, three feet below the surface, considerably 



below the level of the surrounding territory, near 

 human remains, was a vessel of about one pint capa- 

 city, from which portions of the rim, old breaks, were 

 missing. Height, 3.9 inches ; maximum diameter, 4.4 

 inches. The base is imperforate. Its incised decora- 

 tion lacks uniformity. The most interesting portion 

 is shown in Plate LXXII, Fig. 1. 



In caved sand was a to}^ vessel about two inches in 

 height with imperforate base and flaring rim which was 

 unfortunately damaged by contact with a spade. 



A number of additional vessels of ordinary type 

 and size, without decoration, were recovered during the 

 investigation. Some were intact, while others had been 

 intentionally mutilated as to the base. 



Loose in the sand, near the base, was a mass of 

 cherty material about 5 inches by 3.5 inches by 2.75 

 inches. Its shape was ovoid. It was doubtless fash- 

 ioned to do duty as a hammer. A somewhat smaller 

 mass of coralline limestone, not so regularly shaped, 

 lay unassociated, about 3 feet from the surface. 



Sheets of mica, of somewhat irregular shape, some 



so large as 7 inches square, came from various depths. 



Some had perforations for suspension or for fastening to 



garments. These sheets of mica, as a rule, were associated with pebble hammers, 



chips of chert, bits of shell and of sandstone. 



Tavo and one-half feet from the surface, probably on the base, as the mound 

 sloped considerably at that point, with part of the shaft of one human long bone, 

 were one rounded piece of sandstone, one bit of chert, two pebbles, one small frag- 

 ment of earthenware, and many marine mussel shells {Modiola plicatula). These 

 shells lay in bunches, one within the other, showing them to have been inhumed 

 without the animal, and therefore not as food. About 18 inches below this curious 

 medley was an undecorated bowl, imperforate as to base, of about one quart capacity.
