the Cottonwood river to Peabody, making an aggregate distance of 

 230 miles. He also made important observations on the deep borings 

 at different points which he passed, as well as other matters of surface 

 geology. 



The Verdigris river affords another good opportunity for studying 



the stratigraphy of this part of the state. It is not so long as the 



Neosho, but like the latter passes from the younger to the older 



rocks. Its general direction is almost parallel with the Neosho, from 



which it is distant from thirty to forty-five miles. Mr. Piatt was 



entrusted with the task of making a section up this stream, which he 



did in a very satisfactory manner from the state line to Madison, a 



distance of ninety-three miles. Later he did considerable in the way 



of correlating the limestone systems of the two rivers, and in tracing 



the southeastern limits of two of the principal limestone formations. 



He also made observations on such deep wells as lie within his field. 



In order to fully determine the stratigraphy of the eastern half of 



the state many sections must be run in different directions, and the 



oftener such sections intersect, the greater the possibility of checking, 



and thus rendering the work more accurate. With this in view the 



writer made a section from a few miles below Cherryvale along the 



Atchison, Topeka & Santa Fe railroad to Lawrence, and from Ottawa 



to Holiday, a total distance of 168 miles. This section crosses the 



Neosho river section at a sharp angle, at lola, so that a portion of 



the two are very simdar. 



Mr. McClung devoted the greater portion of his time to a study of 

 the coal district in Cherokee and Crawford counties. He also, with 

 the assistance of Mr. Kirk, ran two sections across the coal fields 

 from southeast to northwest, aggregating about seventy-five miles. 

 He made a provisional map of the coal mining district, locating the 

 various shafts and stripping-pits. The subject is such an important 

 one, however, that it is thought best not to publish the results untd 

 further work can be done. 



During our first summer's work, therefore, nearly 600 miles of 

 sections were made and much other work accomplished. This report 

 should be looked upon as preliminary, and it is offered subject to 

 correction, although in the main it is believed to be substantially 



correct. 



The general plan of work adopted for the coming summers includes- 

 the making of additional sections along the Osage, Poitawatomie, 

 Kansas, and other rivers, with sufficient cross sections to furnish all 

 the checks iiecessary. It also includes the gathering of fossils, and 

 of ectmomic products, in order that we may ultimately have a 

 complete survey of this part of the state.
