raphy of the Kansas Coal Measures," 6 ITaworth describes them 

 as follows: "Above them (Topeka limestones) lies another 

 shale bed fifty feet thick, at the top of which lies the Topeka 

 coal, a seam about eleven inches thick, which has been mined 

 in different places. The coal is immediately overlaid by two 

 thin limestone beds, separated by less than three feet of shales. 

 Above the limestone is the Osage City shale, more than 100 

 feet thick, at the top of which is the Osage coal, averaging 

 eighteen or twenty inches thick. . . . Above the Osage 

 coal is a thin limestone system [formation] , superseded in turn 

 by the Burlingame shales, a body about 150 feet thick in the 

 vicinity of Burlingame, and possibly more in places. Both the 

 Burlingame and Osage City shales extend for long distances to 

 the southwest and northeast, and are important landmarks in 

 stratigraphy." Bennett 6 describes the succession at Topeka 

 correctly, but supposes the coal above the Topeka coal corre- 

 sponds to the Osage horizon, instead of to the one already indi- 

 cated in this paper as its equivalent. 



Haworth's statement in Vol. I, p. 162, of the Kansas Survey, 

 is practically a repetition of the one just quoted, but he corrects 

 the correlation of the coals in a foot-note at the bottom of page 

 161. In volume III of the same reports (p. 94) he uses the 

 term "Osage shales" for all the shales between the Topeka 

 limestone and the Barclay limestone. The section is correctly 

 given by Hall in his " Section from Boicourt to Alma," 7 though 

 it is not clear just what is meant by his "Osage City Shales, 

 Coal, and Limestone." 



From the foregoing, it will be seen that the terms "Osage 

 City" and "Burlingame," when strictly applied, are proposed 

 for one and the same set of rocks, namely, those above the 

 Osage-Topeka coal, w 7 hile the shales below the coal and above 

 the Hartford limestone are not designated at all. Later, in 

 Vol. Ill of the University Survey (p. 66), in quoting Doctor 

 Adams's notes, Professor Haworth gives the following : " Sever;/ 

 Shales. — 'Above the Elk Falls limestone is a bed of shales aver- 

 aging fifty to seventy-five feet in thickness, which, with the pro- 

 tected limestones above, forms a light escarpment that may be
