Conway, Horry County. — Several attempts were made to obtain water 
at Conway and elsewhere in Horry County, but without success, as the 
borings were not deep enough. The depth attained at Conway was 
only 160 feet. 
Allien. — The Aiken well has a depth of 558 feet and furnishes an 
abundant supply of excellent water. Water was also found at 543 
feet, and the "chalk" formation under Aiken yields water in fair sup- 
ply at a depth of about 100 feet. A partial record of the Aiken well is 
as follows : 
Feet. 
0-45 red clay. Lafayette formation. 
45-100 sand. \ 
100-130 "chalk" or "kaolin." [ Potomac formation. 
130-465 sand. ) 
465-558 granite. 
A well on a high hill in Hammond Township, 1 Aiken County, found 
a large supply of water at a depth of 120 feet. It passes through sand. 
The well presents the curious phenomenon of a current of air which in 
stormy or threatening weather issues from the orifice with considerable 
force. 
Orangeburg. — There are four wells in this place which yield a satis- 
factory supply of excellent water. The deepest borings were to a depth 
of 1,160 feet, but no greater pressure of water was found there than at 
250 feet. The water rises to within 48 feet of the surface, but pumps 
down to 54 or 56 feet. The following record was furnished through the 
kindness of Mr. George H. Cornelson, of Orangeburg: 
Feet. 
0-42 red clay. 
42-62 water-bearing sand. 
62-122 clay. 
122-132 sand with some water. 
132-232 marls of different colors. 
232-252 sand with fair supply of water. 
252-962 fine sand with shells, sharks' teeth, bones, etc. 
962 6-inch layer of wood. 
962-1,160 fine sand with water.
