tThe several beds of the above section are described mainly from exposures near 
the following localities: Marion concretionary limestone and flint near Marion and 
Burns; shales of No. 17, east of Cedar Creek near Wonsevu, Chase county; Florence 
limestones and flint near Florence and Ft. Riley; shales of No. 10, on Middle Creek 
above Elk, Chase county; Lamellibranch limestone, No. 9, near Four Mile and Six 
Mile Creeks in the southern part of Morris county; shales and shaly buff limestones 
of Nos. 6-8 near Cedar Point, Cottonwood Falls and Matfield Green; and the com- 
plete series of the Strong flint two miles northeast of Council Grove.
