The total thickness of either Section may be estimated roughly at 

 500 feet. 



From the general aspect of the various beds, I suppose them to 

 belong to the lowest part of the gypsum-series, probably the very 

 lowest in this locality. 



In one respect the Kirrind Sections are much more interesting than 



> thin beds.
