feet capping the bluff just above the quarry in the lola limestone. 

 Farther up the river it increases to a thicknes of 15 or 20 feet, but is 

 nowhere a heavy limestone system. It is abundantly exposed at the 

 little railroad station, Carlyle, five miles north of lola, and will there- 

 fore be called the Carlyle limestone. From here it extends southwest, 

 is well represented along the Neosho river at Neosho Falls, and passes 

 beyond to the southwest. It remain visible for about four miles up the 

 river from this place where it disappears beneath the water in the river. 



Above the Carlyle limestone there is a heavy bed of shale and 

 sandstone reaching nearly 150 feet in thickness. It is abundantly 

 exposed around Le Roy, and may be called the Le Roy Shales. In 

 some places sandstone is very abundant. South of Moody station a 

 hill over a hundred feet high is nearly all sandstone, and in other 

 places it is equally abundant. This is undoubtedly the same system 

 of shales lying between the Carlyle and Garnett limestones farther 

 east in the vicinity of Colony. 



Above the Le Roy shales a system of limestone sets in, which is 

 first seen along the river on the high hill-tops about ^w^ miles above 

 Neosho Falls. It consists of two strata separated by 8 or 10 feet 

 of shale. The rocks are hard and compact, and would make durable 

 building stone. In the vicinity of Burlington a number of quarries 

 have been opened, some of which have produced a large amount of 

 building stone. The strata disappear beneath the surface a short 

 distance above Burlington. 



These strata correspond in every respect with the two limestone 

 strata lying at Welda and continuing tt) Ottawa, as is shown by the 

 section from Cherryvale to Lawrence, published in this issue of the 

 QuARTKRi.v. There is little room for doubt that the two are identi- 

 cal. Grouping the two strata into one system, it may be called tem- 

 porarily the Burlington limestone, or the Garnett limestone, leaving 

 the ultimate choice of a name to some future time. 



Above the Burlington limestone there is from 75 to 100 feet of a 

 shale formation which is very sandy in places, protlucing an impure 

 sandstone. It extends for miles above Burlington, producing the 

 wide bottom lands in that vicinity. Above this shale there is a thin 

 limestone system, not over six feet vertically, which is seen on the 

 hill-tops south of Burlington. It is visible along the railroad all the 

 way from Burlington to above Strawn, and may be called the Strawn 

 limestone. 



Overlying the Strawn liiiics.u>iic i> a system of black shales 60 or 80 

 feet thick, which contains much less sandstone than the shale bed last 

 described. A section of it may be seen just south of the railroad 

 bridge above the station.
