times passing into a sandstone ; for example, on Fall river below 

 Charleston. 



On Fancy creek we find no other limestone above that last 

 named for nearly 200 feet above, when we find an ash-blue lime- 

 stone about 2 feet thick, containing Protozoa; this is again cap- 

 ped by 36 feet of sandstone, above which lie 35 feet of shales, 

 with beds of limestone still above ; and 100 feet still higher on 

 the hilltop, at an elevation of 1,235 ^^^^1 another limestone bed 

 appears. Near Twin Falls, also 7 miles east of Howard and 5 

 miles southwest of Charleston, we find limestone beds from near 

 1 165 to 1200 feet above the sea abounding in Chastetes and occa- 

 sionally in Syringapora mtiltattenuata. Most of these limestones 

 also seem to abound in Fusulina cylindrica. 



West of Fall river, at 1081 feet elevation, a limestone occurs 

 abounding in the above named Protozoa^ also a Nautilus and 

 Syringapora multattenuata ; at 1081 bituminous shales are seen. 



On Indian creek. Elk county, at 1050 feet elevation, numerous 

 well preserved fossils were obtained from a limestone, and include 

 fine specimens of J^a//«a subguadrata showmg interior of valve, 



also Nuculana bellistriata^ Edmundia , Schizodus Wheel- 



eri^ Aviculopecten occidentalism and Myalina perattemiata — 

 all well recognized upper coal measure fossils. On hills 4 miles 

 north and 2 miles south, and at an elevation of 1130 to 1150 feet 

 above the the sea, we find the limestones named above as abound- 

 ing in Chastetes, and separated from the Indian-creek fossil bed 

 by sandstones. 



We now come to speak of the "Permian" or limestones of the 

 '' Flint Hills," reaching, in Elk, Greenwood and eastern half of 

 Butler and Cowley counties, from 1 185 to 1700 feet above the sea, 

 or including about 500 feet thickness. 



The following section was observed west of Greenfield (town 

 has since been removed and name changed to Grenola), num- 

 bering from hilltop : 



Sec. A — I. 1.34 feet, including beds of impure drab limestone, shaly and 

 crumbling, with occasional shale beds, with red shales 

 30 feet from bottom. 

 2. 5 feet of bluish-drab or drab limestone containing many good 

 characteristic fossils, including Eiimicrotis kawni. My- 

 alina perattenuata, Aviculopecten occidentalism etc. 

 [This bed is persistent wherever its associated strata are 

 found.]
