PREFACE. 



When I first undertook to make Geological 

 Sections, Maps, &c, it was for my own study and 

 amusement, and I had no thought of publishing my 

 productions ; but as I found most of the elemen- 

 tary works on the subject, to be mere collections 

 of hard names and foreign references, and conse- 

 quently not likely to be looked on by the Ameri- 

 can student, but as a task, I thought I could show 

 something more agreeable nearer home, and by 

 adding historical facts, anecdotes and reminiscen- 

 ces of the city, I might induce some to read and 

 become interested, in the greatest of all sciences ; 

 I therefore enlarged my work, and now, by the 

 advice of my friends, I lay it before the public, 

 hoping, it may at least serve as a stepping stone to 

 the young Geologist.
