Similar, the Nummulites large, white except for rust spots 
and nearly whole. Certainly from near the top of the well. 
Similar to preceding. 
Fragments of Nummulites, Lepidocyclina, Operculina with 
occasional conical Orbitolina. A mixture from higher levels. 
Similar, mostly Nummulites and Orbitolina. 
Similar but fragments of Operculina and Lepidocyclina in 
addition. 
Similar to preceding. 
Few foraminifera, not distinctive. Cristellaria added. 
Similar but with fragments from higher levels. 
A few fragmentary poorly preserved forms. 
Light colored chalky material, occasional foraminifera, 
Cristellaria, etc., Orbitolina from above. 
Similar but with flinty chips at 1600 feet with large rusty iron 
flakes as though casing has been put down at this point or 
new drilling started. 
Light colored crystalline limestone with a few casts of 
foraminifera. 
Similar material with bluish fragments similar to some seen 
at 1450 feet, probably from above. 
Similar. 
Mostly rusted iron flakes from casing. 
Similar to 1900 feet. 
Hard compact crystalline limestone. No foraminifera. 
No indentifiable foraminifera. 
Peculiar fibrous oily material with light colored material from 
above. 
PROBABLE STRATIGRAPHY. 
The intervals between the samples is rather wide, and conse¬ 
quently detailed information is impossible. 
The material at 50 feet suggests that the Chattahoochee has 
already been wholly penetrated and the Ocala reached. At 150 
feet fragments of Nummulites appear and whole specimens at 
various depths below showing that the Eocene Nummulitic hori¬ 
zons appear somewhere below the Ocala, probably somewhere be¬ 
tween the 150 and 50-foot levels. 
At 180 feet the peculiar foraminifera are unfortunately crys¬ 
tallized with a loss of structure so the. age cannot be determined. 
They indicate shallow water as they are clearly worn and rounded 
by water action.
