14 HARPER: EXPLORATIONS IN THE COASTAL PLAIN 
visited in the eighteenth century by Bartram and Michaux, but 
seem to have been untouched in the nineteenth by all botanists 
except Dr. Baldwin, who visited Cumberland occasionally during 
the few years of his residence at St. Mary’s, on the adjacent main- 
land. Some portions of Cumberland island rise about 50 feet above 
sea-level, which is higher than most, if not all, of the other islands 
along the Georgia coast, and probably as high as any part of the 
mainland of Camden County. The floras of the two islands are 
remarkably different, considering their proximity to each other 
and to the mainland. 
On September 4 I visited two interesting bodies of water in 
the southern part of Lowndes County, near Lake Park. Ocean 
Fic. 3. Ocean Pond, Lowndes County. September 4. 
Pond, the larger of the two, is said to be about two miles in di- 
ameter, and is probably the largest pond inthe state. But, strange 
to say, for over fifty years it has been represented seven or eight 
miles from its true position on all maps of the state which show 
it at all. Its water is quite clear and the shore mostly sandy, like 
that of Open Pond in Decatur County, * which I visited the sum- 
mer before. Among other interesting plants seen in Ocean Pond © 
and along its shores were Sagittaria isoetiformis, Hydrochloa fim: 
tans, Ertocaulon septaigulare (no, 1608), Lachnocaulon Beyricht- 
anum (no. 1607), Polygonum hirsutum (uo. 1609), and Nymphaea 
orbiculata (no. 1610).
