Florida geological survey—14TH annual report 
Bruce, were begun as tests for oil in this county. No set of the cuttings 
from either of these wells were procured and operations were suspended 
during the spring of 1921. From a log of the Bruce well it is seen that 
it attained a depth of at least 770 feet. The well drilled west of De- 
Funiak Springs, near Rat Head, is reported to be over 1,888 feet deep. 
Following is the log of a well drilled as test for oil near Rat Head, Walton
