The Chair, in introducing the exercises, made some state- 

 ments explanatory of the principles, objects and history of 

 the Institute, and of the purposes and method of these 

 "Field Meetings." We had pursued this system of gather- 

 ings for several years, and thus far, with signal advantage 

 and enjoyment to all who participated. At these meetings 

 we bring together those who feel an interest in the works of 

 Nature and who make them their especial study ; and we 

 place them face to face with the various phenomena of crea- 

 tion, as they are exhibited in our fields, our hills, and our 

 forests. By these excursions, we are relieved from the ne- 

 cessity of studying these things in the dry, dead cabinets of 

 home ; and the student who walks witli us has a view of 

 them as Nature has herself arranged them, drawing his 

 conclusions from facts undisguised by the interference of 

 man, and free from that partial and imperfect character 

 which will ever be detected, even in the best ordered and 

 fullest collection. Such students of nature are with us to- 

 day ; may we hear from them how they have fared in these 

 respects during the day's rambles.
