This table does not include the Lower Cretaceous, of which 

 the Comanche series 5 is now recognized ; but, as it is the pur- 

 pose of this paper to deal only with the Upper Cretaceous, the 

 section of Meek and Hayden is wholly adequate, since the de- 

 velopment of our knowledge of it in Kansas is largely the result 

 of attempts to identify the members of the Missouri river sec- 

 tion in the territory along the Smoky Hill river. The following 

 sketch gives in chronological order abstracts of the more impor- 

 tant papers : 6 



1855 — Doctor Schiel's Report. The series of limestones from 

 Westport, Mo., to the Little Arkansas he considered to belong 

 to the same formation. There he found "a white, fine- 

 grained, non-fossiliferous limestone, and a red, ferruginous 

 sandstone, out of which Pawnee Rock is formed. The latter 

 was also found on Coon creek, and, from specimens brought by 

 Captain Gunnison, he concludes that it extends up the Repub- 

 lican fork of the Kansas river. It supports a loose conglomer- 

 ate of quartzose rock, which is seen to extend some thirty 

 miles along the Arkansas west of Fort Atkinson. It is prob- 

 able that these strata belong to the chalk formation, which, 

 going westward, we find distinctly represented. About thirty 

 miles further west we meet with another limestone of the Cre- 

 taceous period." 



1856 — Engleman's Report. 7 This gives a general description 

 to Fort Riley. He describes a sandstone along the Republican 

 from above Fort Riley for forty-eight miles, that is, to eighty 

 miles from the fort. He is inclined to think that it cannot 

 exceed 200 or 300 feet in thickness. From Professor Hall's
