HAWORTH: the coal fields of KANSAS. 305 



Above the Osage City horizon no coal in paying quantity has been 

 found in the Coal Measure area of the state. 



RESUME OF STRATIGRAPHY. 



We have now mentioned all the coal producing horizons in the Coal 

 Measures of the state, which may be summarized as follows: — 



COAL BEARING HORIZONS OF KANSAS. 



1. Cherokee Shales: — Located at base of Coal Measures, 450 feet 



thick. 

 Coals: — Columbus coal; Weir City-Pittsburg, lower and upper; 

 strip pit coal in northern part of Cherokee county; vari- 

 ous coals around Oswego; Leavenworth coal. 



2. Pleasanton Shales: — Located above Pawnee limestone and below 



the Erie, or Triple limestone, 235 feet thick, with base 

 550 feet above base of Coal Measures. 

 Coals: — Pleasanton; Boicourt; La Cygne; and Mound City 

 coals. 



3. Thayer Shales: — Located between the lola and Erie limestones, 



from 100 to 250 feet thick, with base about 1000 feet 

 above base of Coal Measures. 

 Coals: — Thayer coal; Brooks coal; Neodesha coal; and Inde- 

 pendence coal. 



4. Lawrence Shales: — Located between the Garnett and Oread lime- 



stones, from 200 to 300 feet thick, with base about 1400 

 feet above base of Coal Measures. 

 Coals: — Franklin county coal, and Douglas county coal. 



5. Topeka Coals:— Isolated, 2075 feet above base of Coal Measures. 



6. Osage City Shales: — Over 100 feet thick, located above Topeka 



coals, and about 2100 feet above base of Coal Measures. 

 Coals: — Chautauqua and Elk county coal; Coffey and Lyon 

 county coal; Osage City coal; Scranton coal; Burlingame 

 coal; Carbondale coal; Dover and Silver Lake coal; and 

 Jefferson county coal. 



PHYSICAL AND CHEMICAL PROPERTIES OF KANSAS COALS. 



But little work has been done upon the Kansas coals in the way of 

 exact physical tests and chemical examinations. Prof. Blake, of the 

 department of physics in the University, years ago made a few tests 

 of a number of varieties to determine their steam producing prop- 

 erties. The results were published in the Transactions of the Kansas 

 Academy of Science, volume 11, page 46, 1888, the summary of 

 which is here reproduced in full:
