DETAII/ED RECORDS. 
The detailed reports which follow were selected because they give 
definite stratigraphic information or information of importance in 
drilling adjoining- wells. While only such records Avere chosen as 
appeared to have been kept with care, the Survey does not guarantee 
their accuracy. Descriptions are given substantially as presented in 
the original records, although the compiler has taken the liberty toj 
make some changes in nomenclature, such as substituting shale for 
"soapstone," and to make other modifications in favor of uniformity] 
and conciseness. When the samples suggest an interpretation radi- 
cally different from the one in the driller's log, both are given, with! 
the former in parentheses. Other interpolations made on the authority! j 
of the compiler are also bracketed.
