At Oketo, Kan., two miles south of the state line, there are 

 large quarries worked in the bands above the cherty limestone. 

 The exposures along the bluffs at Oketo were the same as seen at 

 the state line, except there were a few new bands above the oolitic 

 limestone. The cherty limestone band that has been traced from 

 Blue Springs to the state line and on to Oketo is, beyond ques- 

 tion, the same band that outcrops to the north of Marysville, 

 Kan., and that it is the Florence 1 flint of Prosser's Chase forma- 

 tion. If this correlation is correct, the cherty limestone that is 

 only partly exposed at Holmesville will equal the Strong flint of 

 Prosser's Kansas section, in which case the Chase formation 

 would extend as far north as Beatrice, and the Neosho from 

 Beatrice to Roca. There are some stratigraphical differences 

 noted while comparing the formations of the two states, but this 

 will undoubtedly disappear with more detailed study. ■ The 

 most marked is the occurrence of oolites in Nebraska that have 

 not been reported from Kansas. Prosser calls the variegated 

 band underlying the Florence flint a shale, while the same band 

 in Nebraska is an indurated marl. At all exposures attempts 

 were made to take the dip, but as a rule the readings were any- 

 thing but satisfactory. At Hojmesville and Blue Springs there 

 were places, which appeared to be caused by warping, where
