ALTAMAHA GRIT REGION OF GEORGIA 113 



peculiarity which would account for it. The places are neither 

 on hilltops or steep slopes nor in deep valleys, but their proximity 

 to each other is doubtless significant. 



In various other parts of the region are small areas of wet woods 

 having a flora somewhat intermediate between the above and 

 that of the common branch-swamps, but these are not yet very 

 well understood. 



On a hillside sloping toward the swamp of the Ocmulgee River 

 in the northeastern corner of Coffee County opposite Lumber 

 City, and about a mile from the river, is a peculiar moist belt 

 extending horizontally along the hillside for some distance, 

 marked by a dense growth of shrubs, chiefly Alnus rugosa. 

 Following this same belt to a railroad cut near by, it was found 

 to be connected with a stratum of Altamaha Grit there exposed. 

 There may be other similar places in the region, but I have not 

 yet come across them. 



The Big Pond in Appling County (mentioned in a previous 

 paper 1 ) is another interesting feature, probably unique for the 

 Altamaha Grit region. What little I could see of the vegetation 

 around its edges resembles that of sand-hill bogs and non-alluvial 

 swamps. What may grow in the pond itself is entirely unknown. 



The occurrence of a few "bottomless" ponds, usually called 

 lime-sinks by the natives, in the Altamaha Grit region has been 

 mentioned above. The only example of this that I have seen 

 (one in Coffee County) contained no floating plants, and the vege- 

 tation around its edges (trees, shrubs, and herbs), resembled that 

 of a branch-swamp more than that of any other kind of pond. 

 It was surrounded at least in part by moist pine-barrens. 

 Further study of these places is needed. 



The sandy west bank of the Ohoopee River near the center of 

 Tattnall County, opposite the sand-hills and near some of the 

 rock outcrops already mentioned, has a flora resembling in part 

 that of sand-hills, hammocks, and rock outcrops, but with few if 

 any species peculiar to it. Somewhat similar conditions are met 

 with along the Ocmulgee River opposite Lumber City. 



This about completes the classification according to habitat of
