Rogers'. 2d. The strong and uniform dip of all the rocks to 

 the west. This dip will average perhaps ten to fifteen feet per 

 mile. 3d. The entire series is fossiliferous. This is the best 

 fossil field in the territory that has come to my knowledge, and 

 should be thoroughly studied. The ledges numbered 6, 7 and 8 

 particularly will reward investigation. All of these ledges 

 are well exposed on the bluff back of Ben. Avant's farm, 

 thirty-five miles southeast of Pawhuska. 



From near Pawhuska to Winfield, Kansas, our route lay 

 across the Flint hills. Massive ledges of limestone with flinty 

 concretions, alternating with beds of calcareous shale, composed 

 practically all the rock seen. The only sandstone noticed was 

 on Beaver creek and near Maple City, spoken of above. The 

 Flint hills have been too often described to require more than 

 a passing mention in this place. 



The results of this trip may be summarized as follows : 



1. The Flint hills do not extend as far south as the Seminole 

 country. 



2. The sandstone, which is well developed in the eastern 

 part of Chautauqua County, Kansas, continues uninterruptedly 

 southward east of the Flint hills, beyond the North Canadian 

 river. 



3. The eastern limit of the Red-beds in southern Oklahoma 

 is not far from the western part of the Seminole country. 



4. A line of coal beds extends north and south near Bartles- 

 ville, Skiatook, Dawson, Tulsa, Okmulgee and Henryville. 

 These beds vary much in thickness. 



5. There is no reason to doubt that gas and oil will even- 

 tually be found near these coal beds.
