ARTESIAN WELLS ON THE ATLANTIC COAST. 
[BULL. 138. 
but it is not known that they are reached by other wells to the south 
and east. 
There appears to be a wide area for several miles about Charleston in 
which waters are found in wells averaging about 400 feet deep, in cal- 
careous beds at the base of the Eocene, possibly, the eastward repre- 
sentative of the buhrstone horizon, but nothing is known of the extent 
of this water beyond this group of wells. The failure of the Conway 
and Georgetown wells was probably due to insufficient depth. 
EASTERN GEORGIA. 
This region was not so thoroughly canvassed for well data as the 
States to the north, and I can now present little more than a list of 
some of the wells. The location of wells is shown on PI. XVII. 
The geology of eastern Georgia is very similar to that of the adjoin- 
ing portion of South Carolina, with a succession of widely extended 
east-sloping sheets of clays, sands, and marls, which thicken gradually 
to the eastward. The region has not been studied with sufficient care 
by any geologist to afford data for even a general outline of the strati- 
graphic succession, so that any attempt at present to discuss the 
geologic horizons of the waters or to prognosticate on a geologic basis 
is out of the question. 
The success of most of the wells, especially those along the coast, 
gives great encouragement that the water-bearing beds underlie a wide 
area of the Coastal Plain region of the State at moderate depths. 
The large supply of water from the twelve wells at Savannah, and the 
height to which the waters rise in the flowing wells along the coast 
from St. Catherine Island to Fernandina, Fla., are features which give 
great prominence to the underground water resources of eastern 
Georgia.
