4: GEOLOGICAL SURVEY OF WISCONSIN. 



results of the survey, a just and generous public will award a due 

 measure of honor to the hand that organized and gave it direction at 

 its inception. 



The like comity in relation to the revision of the report of 1875, 

 extended to Dr. Wight, \vas declined, except the privilege of reading 

 the proofs, but he has been kind enough to assure me that nothing has 

 been omitted from his report that it is desirable to retain. 



The revision of all these reports has been closely confined to the 

 elimination of administrative and duplicate portions, and everything 

 of a geological nature has been retained, even though it were only 

 provisional in character, and this has been done to the exclusion of 

 portions of my own and of my associates' manuscript. While pub- 

 lishing thus fully and scrupulously the reports of my predecessors, it 

 is but just to myself to disclaim any responsibility for the views pre- 

 sented. 



Since these reports, besides being themselves the earlier annals of 

 the survey, contain historical sketches, they are grouped together to 

 form the opening historical section of the volume. 



The annual report for 1876, submitted by the writer, was promptly 

 published, and hence no part of it will find a place in this volume. 



The annual reports of the assistant geologists, being their own in- 

 dependent productions, were placed in their hands, and will be found 

 incorporated in their reports upon the districts assigned them.
