PREFACE. 
Volume II of the University Geological Survey follows close 
upon the appearance of volume I. Those unacquainted with 
the work already done may wonder how such can be possible 
when so small an amount of funds has been used by the Survey. 
It may be stated, therefore, that material for this volume has 
been accumulating for years, so that it by no means represents 
the work of the past year only. 
In the preparation of volume IJ the writer has been assisted 
by the following workers, each of whom volunteered his serv- 
ices, and consequently cost the state nothing but his actual 
expenses: Prof. C. S. Prosser, of Union College, Schenectady, 
N. Y., with his two assistants, Mr. Je We Beedes ol mMlopelkcar, 
and Mr. C. N. Gould, of Winfield; Mr. W. N. Logan, a grad- 
uate of the University, and now principal of public schools, 
Pleasanton; and Prof. S. W. Williston, professor of palaeon- 
tology in the University, and regularly a member of the Survey 
staff. The state has consequently been greatly benefited by 
their gratuitous contributions of service. 
The drawings for the five etchings forming the figures in the 
text, and all the plates excepting the half-tone reproduction of 
photographs, were made, excepting figures 12 and 13, by Miss 
Harriet M. Huntsman, of Lawrence, the same artist who con- 
tributed so largely to volume I. Her work needs no comment. 
The engraving was all done by Blomgren Bros. & Co., of Chi- 
cago, whose work likewise speaks for itself. lois Jel,
