HAWORTH AND BENNETT.| History of Field Work. 55 
from which place he went to the Agricultural College of Mis- 
sissippi and became state geologist. 
Prof. E. B. Knerr, of Midland College, Atchison, worked 
with the University Geological Survey during the summer of 
1895. He made a geological section from Atchison west en- 
tirely across the Coal Measures and the Permian, and pub- 
lished the same in volume I, University Geological Survey re- 
ports. 
Prof. E. H. S. Bailey, head professor of chemistry in the 
University of Kansas, for a number of years has made a spe- 
cialty of mineral waters in Kansas and elsewhere. He pub- 
lished volume VII of the University Geological Survey reports, 
which is devoted entirely to the mineral waters of the state. 
Dr. BE. C. Case, of Ann Arbor, Mich., for a number of years 
was a student at the University of Kansas in both the under- 
graduate and graduate departments. In this connection he 
made a number of investigations, particularly in western 
Kansas. In volume IV of the University Geological Survey 
reports he published a paper on one of the divisions of fossil 
turtles. 
Dr. C. KE. McClung, now of the zodlogical department of the 
University of Kansas, also published a paper in volume IV 
on Kansas chalk, dealing principally with the micropaleon- 
tology of the same. 
Dr. G. P. Grimsley for a number of years was connected 
with the University Geological Survey, making a special study 
of gypsum and its products. He prepared the greater portion 
of volume V of the Survey reports, which is devoted entirely 
to gypsum and the various gypsum industries. 
Professor Erasmus Haworth began the work of the Univer- 
sity Geological Survey of Kansas during the summer of 1893 
and has worked at it continuously from that time to the pres- 
ent. In his capacity as state geologist he has had general over- 
sight of all the work done by the Survey excepting that done 
by Professors Williston and Bailey and their assistants. 
In addition to the above workers a large number of advanced 
and graduate students have devoted from one to two summers 
to work on the Geological Survey, some of whom have been 
joint authors in various papers and reports, but a number of 
whom have not yet reached such a prominence. Some of them 
have grown into geologists of note; a few of them have taken 
up other lines of work and become widely-known authorities,
