Grahamville, Beaufort County. — The wells are on the plantation of 
J. S. Claghorn, 3 miles from the village. Their depth is 164 feet, and it 
is stated that clays, marls, and shells, with some rock strata, were pene- 
trated to a calcareous conglomerate, with minute shells and sharks 
teeth, which is the water-bearing bed. The water flows and furnishes 
about 200,000 gallons a day, but the amount is decreasing. It is soft 
and sulphurous. 
Mays River. — There are a number of wells on Mays Eiver Neck which 
yield water supplies, some of which are very pure, while others are too 
sulphurous to be palatable. 
At Snyder & Nuttle's sawmill a well 106 feet deep furnishes a con- 
tinuous overflow of pure water, the flow of which is affected somewhat 
by the tides. 
Four wells on the rice plantation of Col. J. H. Estill, on South Mays 
Eiver Neck, furnish a large overflow of pure water from an average 
depth of 360 feet. The well at the residence of Col. J. H. Estill, on 
Mays River, has a depth of 190 feet, but the water is highly sulphu- 
rous. Capt. T. R. Hey ward's well, on Mays River, has a depth of about 
800 feet, and the water rises to within a foot of the surface, but is too 
highly sulphurous for use. 
There are wells in Bluffton which average 165 feet in depth and have 
an overflow to about 13 feet above tide level. It has been found in this 
district that the exclusive use of artesian waters moderates, if it does 
not entirely overcome, the baneful effects of the malaria which is so 
prevalent there. 
Port Royal. — At the United States naval station a 6-inch boring 
was made to a depth of 255 feet, but the water found is too impure for 
domestic use and is very small in amount. Three wells, having a depth 
of 60 feet, now afford an abundant supply, but the water is hard and
