PUBLICATIONS 



OF THE 



Wisconsin Geological and Natural pistory Survey. 



1. BULLETINS. 



The publications of the Survey are issued as bulletins, which are num- 

 bered consecutively. Each bulletin is independently paged and indexed, 

 no attempt being made to group them in volumes. The bulletins are 

 issued in three series, 



A. Scientific Series. The bulletins so designated consist of original 

 contributions to the geology and natural history of the state, which are of 

 scientific interest rather than of economic importance. 



B. Economic Series. This series includes those bulletins whose in- 

 terest is chiefly practical and economic. 



C. Educational Series. The bulletins of this series are primarily 

 designed for use by teachers and in the schools.
