5A University Geological Survey of Kansas. 
for the State Survey, has made a complete faunal section from 
the base of the Coal Measures to the Permian, and has pub- 
lished the results in a series of articles in the University 
Science Bulletin, an outline of which is included in this vol- 
ume. Also, he has rendered valuable assistance in the prepara- 
tion of geological maps of the state, published for the first 
time with this report. 
Dr. A. F. Rogers began his work in Kansas geology in con- 
nection with the investigations of lead and zinc ores and is the 
author of part III, volume VIII, Special Report on Lead and 
Zinc, just issued from the press. This paper is devoted en- 
tirely to the mineralogy of the region. Subsequently he as- 
sisted Dr. J. W. Beede in field and laboratory work in pre- 
paring their paper on the faunal section of the Coal Measures 
of Kansas mentioned above. 
Rev. John Bennett first began working for the University 
Geological Survey in the summer of 1894. Previous to this 
time, while residing at Fort Scott, Kansas City, Savannah, 
and Cameron, Mo., he had become intimately acquainted with 
the invertebrate paleontology of the Coal Measures within the 
environs of his different places of residence. He has been 
connected with the Kansas Survey intermittently from 1894 
to the present time, and has done more field-work in tracing 
out the individual horizons than any other one person. His 
first publications on Kansas geology consist of four papers in 
volume I of the University Geological Survey reports. Since 
that time he has been identified practically with every piece 
of work done by the University Geological Survey of Kansas 
which has a bearing in-any way on the stratigraphy of the 
Coal Measures. At irregular intervals during the last few 
years he has been employed by the United States Geological 
Survey to assist in certain stratigraphic investigations made 
by Doctor Adams, which work took him partly into the Coal 
Measures of Kansas and partly into the areas covered by the 
same formations in Oklahoma. 
Prof. W. N. Logan worked with the University Geological 
Survey of Kansas during the summer of 1896 and prepared 
a report covering the results of his field-work which was pub- 
lished in volume II of University Geological Survey reports. 
Later, he spent a few weeks in assisting in the stratigraphic 
work in the Coal Measures. Later he held the position of 
professor of geology in St. Lawrence University, New York,
