cipally by the department of physical geology, although the de- 
partment of paleontology has added a brief description of the 
paleontology of the Cretaceous and later formations of the state. 
It is a companion to Volume I and covers the western part of the 
state similarly to the way Volume I covered the east. It deals 
principally with the stratigraphic properties of the Cretaceous and 
younger formations, paying but little attention to the economic 
phases of the state. 
A report is now in preparation by this department to the state 
board of irrigation on work done for them during the past two 
summers. <A plan of cooperation was effected by means of which 
the department of physical geology of the University combined 
with the State Board of Irrigation in making investigations in the 
western part of the state. A large proportion of the data presented 
in this volume was gathered in that way. This portion of the re- 
port of the State Board of Irrigation is practically a report of the 
University. 
Other volumes are in preparation. This department has two 
volumes more than half completed devoted entirely to economic 
subjects, which will cover the topics of lead and zine ores, the mining 
and metallurgy of the same; coal; oil and gas; salt; and gypsum. 
The report on these subjects will constitute Volumes III and IV. 
The department of paleontology likewise is preparing a monograph 
on the vertebrate paleontology of the state which it is hoped will 
be published during the next two years. Likewise the department 
of chemistry is preparing a report on the mineral waters of the 
state which may be expected within a year or two. 
For the present at least the octavo volume will be the style of 
publication adopted. Bulletins, the recent form of overflow pub- 
lications so generally adopted in America, are unnecessary, because 
our University Quarterly, a regular publication, meets such require- 
ments. 
It should be remembered by the scientific reader that these re- 
ports are intended primarily for the masses of the citizens ‘of 
Ikansas, and that therefore an elementary character must be pre- 
served, not however, it is hoped, at the expense of*scientific accuracy. 
Divers elementary explanations must be given, and rudimentary
