Rig used, standard. Diameter of well, 10 inches from top to bottom. Well was drilled 
for oil and shows were reported at several depths. A strong sulphur water was struck at 
1,386-1,400 feet, but no salt water was found. Fresh water was struck from 18 feet down- 
ward at many horizons and gave much trouble in drilling. Water stands 2 feet below 
surface 
351. Well at Deland, Volusia County. 
[Begun June 17, 1905; completed August 8, 1905. Authority, H. E. Smith, driller. Samples preserved.]

limy beds that are in part at least of Pliocene age.
