284 Harper: BoranicAL EXPLORATIONS IN GEORGIA 
On the 22d I was back in Effingham County, and in the after- 
noon walked from Guyton to Springfield, the county seat, about 
six miles back from the railroad (nos. 934-938). The pine-bar- 
rens around Guyton differ from those farther inland in being more 
level and full of shrubs, mostly //ex glabra, with some Xolisma 
ferruginea and two or three small species of Quercus. In the

and probably some distance beyond. Springfield is on the divide

about seventy-five feet above sea-level. 
On June 24 I returned to Bulloch County, by way of Dover, 
Statesboro and Pulaski, collecting a few plants (nos. 939-943) at 
the latter place before starting across the country to my destina- 
tion. For the next ten days I continued my studies of the flora of
