Introductions^ and Acknowledgments 



The material of this paper was prepared with two objects in view : first, 

 to describe and interpret some of the sections exposed in the vicinity of 

 Waterville, and thus add to the small amount of detailed literature exist- 

 ing on the Pleistocene of Maine ; second, to add to the list of Pleistocene 

 fossils of Maine, as published by various workers and tabulated by Clapp,^ 

 a few forms collected here during the past five years. The facts pre- 

 sented were collected in connection with work with my classes at Colby 

 College, supplemented by some work during the summer. The identifi- 

 cations have been made through the kindness of Prof. E. W. Berry, of 

 Johns Hopkins, to whose encouragement, indeed, is due the preparation 

 of this paper.^
