this important and interesting field. During the past year Mr David 

 White, paleobotanist of the United States Geological Survey has 

 given our collections careful examination and has expressed his con- 

 viction of their great importance and completeness. It is proposed 

 with the aid of Mr White to elaborate the more interesting part 

 of these plant remains, and he has in accordance with this plan begun 

 preparing an introductory member of a series of papers relating to 

 this subject. 



Investigations at Rondout. Some months of the year were re-
