The figures in the first column of the above log represent the dis¬ 
tances for which each individual stratum was encountered. As the 
dip of the beds is between 65° and 80°, these amounts are far in excess 
of the actual thickness of the respective beds. 
From the log of well No. 18 it seems probable that the thickness of 
the productive sands at the several horizons is slight.
