PUBLICATIONS 



OF THE 



Wisconsin Geological and Natural pstory 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.
