ARTESIAN WELLS ON THE ATLANTIC COAST. 
[bull ins 
The iron works at Beaufort obtain water from a depth of G3 feet in 
large amount and excellent quality, suitable for all uses. 
Florence. — Several wells have been bored at Florence, one of wiiich 
reached a depth of 1,335 feet. They are successful, but the waters 
have not been fully utilized as yet. For the deep well, Capt. E. W. 
Lloyd has given me data, and Dr. McCorkle kindly permitted me to 
examine some of the borings. The borings were as follows: 
Feet. 
10 reddish buff clay. 
20 light huff loam.' 
30 gray sandy clay. 
40 gray sandy clay (more sandy). 
501 
\ gray sandy clay (less sandy). 
60J 
60-100 gray sandy clay (varying amount of sands). 
105 gray sandy clay with lignite. 
1 10 coarse gray sand. 
120 moderately coarse gray sand with lignite and iron sulphate. 
150 moderately coarse gray sand ; micaceous. 
210 Aery line gray sands. 
220 coarse gray sands. 
350 coarse gray sands ; reddish tinge ; few quartzite pebbles. 
700 coarse gray sand from sandstone. 
From 400 feet to 008 feet, clays of white, red, and brown colors are 
reported. The brown and gray sandstones began at 608 feet and were 
bored through to 1,335 feet, where a hard black rock stopped further 
progress. This sandstone is of the Newark formation, and the black 
rock was no doubt a sheet of trap, such as frequently occurs in that 
formation. The lowest water was at 1,215 to 1,220 feet. It rose to 
within 18 to 20 feet of the surface and was pumped 100 gallons a minute 
when tested. An analysis made by M. B. Hardin, of Olemson Agri- 
cultural College, at Fort Hill, is as follows:
