ON THE FRESH-WATER SHELL-HEAPS OF THE ST. 
: JOHNS RIVER, EAST FLORIDA.. 
BY JEFFRIES WYMAN, M. D. 

Tue St. Johns River, on the banks of which are to be 
seen the mounds described in the following pages, has, in 
several respects, a peculiar interest. It rises near the mid- 
dle of the eastern half of the peninsula of Florida, in two 
series of lakes and swamps of great extent, one of which 
finds its outlet through the upper portion of the main stream, 
and the other through the Oklawaha, the largest of its tribu- 
ties. These waters are separated by land scarcely rising 
above their level, from another chain of lakes and swamps 
Which have an outlet southwards through the Kissimmee, 
and thence into the great lake of Okee-Chobee, which has an 
‘tea of about eight hundred square miles. Other waters, 
Starting from the same region as the preceding, but separated 
om them by a low range of sand-hills, are discharged west- 
wards into the Gulf of Mexico, chiefly through the Withlo- 
“Ootchee. Though extremely crooked, the general course 
of the St. Johns is somewhat to the west of north, and in its 
Various windings is supposed to traverse a distance of three 
dred miles. Its frequent enlargements, as at Lake Har- 
a Ney, Lake Monroe, Lake George, and its great breadth
