United States. 
In the United States the Permian apparently occupies a 
place in the geological chronology not represented by any strata 
in Europe. Hence all attempts to correlate the Permian of this 
country with that of Europe have proven futile.^ Permian was 
first reported from this country by Jules Marcou in 1853, west 
of Zuni in Arizona, and in Indian Territory. 
In West Virginia and Pennsylvania over 1000 feet of the 
Upper Barren Measures (1044 feet in Monongalia county. West 
'Virginia) have been referred to the Permian upon evidence of 
the flora. The beds are there known as the Dunkard Creek 
Series, and are conformable with the lower series.^ The Wasatch 
Section, Utah, constructed by the Geological Survey of the 40th 
Parallel, shows 30,000 feet of conformable strata of which the 
upper 650 feet, characterized by clays, marls and limstones, 
have been referred to the Permian.^ The Kanab Section, Ari- 
zona, constructed by Walcott, shows 710 feet of Upper Per- 
mian characterized by gypsiferous and sandy shales and marls, 
with impure shaley limstone at the base. Also 145 feet of 
Lower Permian, characterized by more massive limestones.^ 
Permian has also been studied in Illinois, Indiana, Nebraska, 
Missouri and Indian Territory. Also in Nova Scotia, New 
Brunswick and Prince Edward’s Island. But in Kansas and 
Texas the work done in the Permian is so extensive and impor- 
tant as to deserve a more detailed account.
