AUTHOR S PREFACE. XIX 



work by Field Assistants R. M. Gawthrop and D. D. Teets, Jr., 

 who made the maps and prepared a large part of the tabulated 

 matter. 



Part IV, treating of the Paleontology, is the exclusive work 

 of Dr, W. Armstrong Price, Paleontologist, who made the neces- 

 sary collections in the field, and described the fossil forms. 



The chemical analyses and calorific tests, except a few taken 

 from previous Reports of the Survey, were made by J. Berghius 

 Krak, Assistant Chemist, working under the direction and with 

 the assistance of B. H. Kite, Chief Chemist. In addition to the 

 analyses published in the text, nineteen other samples of coal, 

 limestone and clays were collected in the field and would have 

 appeared in print had not the reduced appropriation of the last 

 State Legislature caused retrenchment in all the activities of the 

 Survey, making it impossible to complete these analyses, as well 

 as eliminating many valuable well records that might have been 

 published. 



Special acknowledgment is here made of the hearty manner 

 in which many oil and gas companies, and independent operators, 

 cooperated in furnishing valuable well records, secured at pri- 

 vate expense, without the inclusion of which this volume would 

 be incomplete. Credit for all such material furnished is given 

 in the text. 



Finally, the author expresses his obligation to JJr. I. C 

 White, State Geologist, without whose careful supervision and 

 valuable suggestions this Report would lack much of whatever 

 merit it may have.
