The Geuda Salt Measures of Cragin are correlated with 
the Marion of Prosser. Professor Prosser objected to the ten 
divisions of the Cimarron Series as made by Cragin, on the 
ground that the differences between the numerous formations 
were largely local, and could not be recognized over any con- 
siderable extent of territory.^ He regarded the two divistofis of 
Cragin as formations, and assumed the Cave Creek Gypsum as 
the dividing line between the two. The Big Basin Sandstone, 
the uppermost formation of Cragin’s Permian, is correlated by 
Prosser with the Comanche.^ He follows Cragin in referring 
all the Red Beds to the Permiarr. 
The Cretaceous and Tertiary in Kansas are unconformable 
on the Red Beds, while in some places the whole Cimarron
