BROADHEAD CARBONIF. ROCKS OF EASTERN KANSAS. 489 



Uta^ Eumicrotis hawni^ Aviculopinna americana, Macrodon 



, Nautilus occidentalism Orthoceras . 



A more recent examination shows the following in cut of St. 

 Louis and St. Francisco road west of Beaumont, on a high ridge : 



1. 4 feet gravel bed. 



2. 4 '* shales. 



3. 4 ♦' buff limestone, abounding in Myalina perattenuata, M. kansas- 



ensis. Aviculopecten occidental^- Monotis and Athyris Plen- 

 rophorus abounds in a lower stratum. 



From the lower and more crystalline beds near base of the Per- 

 mian I obtained on Spring creek, Greenwood county, fine speci- 

 mens of Allorlstna granosus^ A, subcuneata^ Pinna per acuta., 

 Productus semlretlculatus^ Nautilus capax, and Fusullna 

 cvllndrlca. These above named are the principal fossils ob- 

 served and are typical of the Kansas Permian, but most of them 

 I have also obtained from known upper coal measure rocks of 

 Missouri. 



The highest coal of the series was observed in Greenwood 

 county, where Wolf branch runs into Spring ereek. Its position 

 is probably about the base of the Permian or top of the true 

 upper coal measures. Its associated rocks are as follows : 



1. 2 feet grayish-brown limestone. 



2. I " shelly bluish-gray limestone. 



3. il " blue clay shales. 



4. 3 inches shaly coal. 



5. 2\ " soft coal, poor quality. 



6. 2>T, feet of blue clay shales. 



About the year 1S67 the magnesian limestones of Kansas began 

 ta attract attention. The first was exported from Junction City, 

 was cut into shape by means of a common saw and shipped to 

 Kansas City and other places. It proved too weak, and other 

 quarries were sought. From Maryville, Kansas, it was brought 

 to St. Joseph, Mo., in large quantities, and used in the bridge 

 piers at that place. Some of this was too soft, but the general 

 character of the Maryville rock is good. At present there are 

 numerous quarries in the valley of the Cottonwood from Cot- 

 tonwood Falls to Florence, and rock of an excellent quality is 

 exported. 



Good quarries could be opened nearly everywhere in the "Flint 

 Hills," and the hillsides west of Greenfield are everywhere strewn
