E. E. ROSATRE AND O. C. LESTER, JR. 
at the time of this detail, made a depth calculation of 800 feet to cap 
or salt, at the intersection of the profiles. The agreement with the 
the recording points pass well beyond the salt flank. The junior writer, 
results of the well later drilled at this point was very satisfactory.

line. The only other check of this outline was made on the northeast
