ALTAMAHA GRIT REGION OF GEORGIA 



69 



Euphorbiaceae, and Leguminosae are not represented at all. 

 As in the preceding list, most of the species are confined to the 

 coastal plain. 



7. Rivers and Creeks of the Second Class. 



In the classification of streams on a preceding page those which 

 rise in the upper third of the coastal plain are mentioned. To 

 this class belong the Ohoopee (see Plate VIII, Fig. 2, and IX, 

 Fig. 1 ) and Little Ohoopee rivers, which rise in Washington 

 County, join with each other in Emanuel, and discharge into the 

 Altamaha in Tattnall, also Gum Swamp Creek, which rises in 

 Twiggs County, and unites with Alligator Creek to form the little 

 Ocmulgee River just before it discharges into the Ocmulgee near 

 Lumber City. These doubtless carry more calcium carbonate in 

 solution than those previously mentioned, because they originate 

 in more calcareous regions, and this is probably the principal 

 reason for the difference in the flora of their swamps.
