INTRODUCTION. 
The investigation upon which this paper is based was made dur- 
ing the summer of 1906. The work was done as J. D. Whitney 
Scholar for 1906, under the direction of Professor Woodworth, to 
whom I am indebted for many suggestions, especially as to field 
methods and interpretations. The field expenses were paid by 
Harvard University from the Josiah Dwight Whitney fund for geo- 
logical field study. Mr. Harold C. Durrell of Cambridge, Mass., 
accompanied me at his own expense during most of the summer, 
very graciously assisting me in many ways. 
The district studied includes e hiefly that portion of Vermont which 
lies north of the middle of the state, and west of the divide between 
Lake Champlain and the Connecticut River. The work was extended 
to Shefford Mountain and Brome Mountain in southern Quebec.
