Nineteenth annual Meeting. 51 



Woodson county, in a paper entitled "The Igneous Rocks of Kansas,"' and con- 

 tributed papers on "Fossil Wood" and "The Dacotah Formation." Professors Pat- 

 rick, Kedzie, Failyer, Bailey, and Willard, have given analyses of minerals and 

 mineral waters. In 1883 the Academy contributed to the expenses of an exploration 

 in the Northwest by Mr. Hay, the results of which were published in the Transac- 

 tions, under the title of "A Preliminary Report on the Geology of Norton County." 

 In this report the tertiary deposits of the region examined were recognized as be- 

 longing to two epochs — the pliocene and miocene — separated by a period of ero- 

 sion, the lower one being also shown to rest on eroded surfaces of the underlying 

 cretaceous deposits. Papers read at the last meeting (November, 1885) of the 

 Academy, (of which the Transactions are not yet published.) give discoveries south 

 of the Arkansas, showing large development of Jura-triassic strata in Harper, King- 

 man, Barber, Comanche, and Clark counties, and traces of former extension of ter- 

 tiary strata as far east as Wichita, and great extension of quaternary formations. 



Paleontology has been advanced considerably by the collections of Kansas geol- 

 ogists. Prof. Mudge's name has been attached by eastern authorities, such as Meek 

 and Lesquereux,.to new species both faunal aiad floral. Prof. Mudge also discovered 

 the tracks on the Osage flagstones; and he records in his report as State Geologist, 

 tracks on the sandstones of central Kansas. Frank H. Snow, Professor of Natural 

 History at the State University, and a valued helper of the Academy, has contributed 

 among other papers "Notes," accompanied by a lithograph, on the "Dermal Cover- 

 ing of a Mosasaur," which is in the collection of the University. Professor Patrick 

 reported on the protozoans contained in Kansas chalk. W. Wheeler has given notes 

 on a fossil tusk. Mr. Silas Mason supplied a list of fossils found in Riley county 

 (Permo-Carboniferous). Kansas Cretaceous and Tertiary fossils have by their num- 

 ber and importance served to bring those formations into notice, and eminent east- 

 ern paleontologists have not only examined Kansas fossils but employed collectors 

 for long periods to obtain them. Prof. Mudge, Dr. S. W. Williston, and Mr. Charles 

 Sternberg have sent many Mezozoic and Cenozoic fossils to Yale College and else- 

 where. Mr. Silas Mason has sent the Philadelphia Academy of Science large quan- 

 tities of fine specimens of the Dacotah and Carboniferous floras. Professors Meek, 

 Cope, Marsh and Lesquereux have been here and personally examined the horizons 

 which have yielded such abundant illustration of the ancient life. Dr. Hayden has 

 also contributed to the definition of Kansas formations. The State reports of Illinois 

 have been used by Professor St. John as media for describing Kansas paleontologi- 

 cal phenomena. 



The Kansas City Review has been used as a favorite medium for conveying scien- 

 tific information by scientists of Missouri and Kansas. Professor Broadhead, of 

 the Geological Survey of Missouri, has in its pages several times contributed infor- 

 mation about Kansas geology. In one article he narrates an exploration in southern 

 Kansas, in which he defines the western boundary of the coal measures in that region. 

 It is remarkable that his line between the coal measures and the permian is a con- 

 tinuation of the line in northern Kansas given in Long's map, before referred to. 



Reports and papers now awaiting publication will alter somewhat the geological 

 map of the southwest of the State, and sections will indicate that there is now recog- 

 nized an easterly dip in the west part of the State, which is not what was generally 

 thought a few years ago. The following may be taken as the now known order of 

 Kansas strata: 



Lower Carboniferous, ( Keokuk Limestone.) southeast corner of the State. 



Coal measures. 



Permo-carboniferous, across the State.
