sas, excepting in his paleontological investigations of material

Meek, Hawn and Swallow in early publications, particularly in 
connection with discussions of the Permian in the Great West. 
Prof. J. S. Newberry, like Shumard, did little, if any, work 
in Kansas, but his name is intimately connected with discus- 
sions on Permian geology in those early days. Professor New- 
berry was one of the best and greatest workers America ever 
produced. In addition to his duties as professor of geology 
in Columbia University he found time to traverse almost the 
entire continent and to write reports aggregating thousands 
of pages. His closest relation to Kansas was in connection 
with his explorations in New Mexico and the Southwest. 
_ During the second division of time, as outlined early in these 
pages, no very extensive or continuous work was done in the 
entire state; but nevertheless in the aggregate a great deal 
of valuable knowledge was gained. Prof. B. F. Mudge, while 
located at the State Agricultural College, at Manhattan, and 
afterwards while making collections for eastern institutions, 
published a number of papers devoted to different phases of 
Kansas geology, some of which were particularly valuable. 
He published principally in the biennial reports of the secre- 
tary of the State Board of Agriculture, but also we find papers 
by him in the reports of Dr. F. V. Hayden for 1876 and 1877, 
in different volumes of the Kansas Academy of Science, and 
in McFarland’s American Geological Railroad Guide for 1879. 
One of his most noted reports is on the lead- and zinc-mines 
of Galena and vicinity. He also made geological sections 
across the entire state and published a preliminary geological 
map. 
Mr. O. St. John, formerly connected with the Iowa State 
Geological Survey and Doctor Hayden’s Geological and Geo- 
graphical Survey of the Territories, published a paper of a 
general nature on “‘Kansas Geology” in the Fifth Annual Re- 
port of the secretary of the State Board of Agriculture in 
1887. Soon afterwards he became engaged in private geo- 
logical work, whereupon his publications ceased, much to the 
regret of all geologists acquainted with him. 
Prof. Robert Hay was a veteran Kansas geologist. He he- 
gan publishing papers on Kansas geology in the Transactions 
of the Kansas Academy of Science as early as 1882 and con- 
tinued without interruption until the time of his death. He
