1897] Field Excursion to Chelsea. 127 



district, there were noted and obtained by the members of the 

 Geological Section, several interesting rocks of Archaean age. 



Principal Pollock, of Aylmer, an ardent student of geology, 

 is. about to devote much of his time to the study of petro- 

 graphical questions in this district, and we hope to have con- 

 tributions from his pen in the Ottawa Naturalist. 



Dr. Fletcher was then called upon and spoke at length on 

 the plants and insects of interest which were collected, observed 

 or captured during the day. He also spoke on the birds which 

 were seen. An interesting addition to our local flora was made 

 in Deschampsia flexuosa — a species new to the Flora Ottawaensis. 

 In his usual happy, entertaining and practical style. Dr. Fletcher 

 interested the large assemblage present, so also did Mr. Andrew 

 Halkett, who spoke on general zoological topics, and Mr. A. E- 

 Atwood, on " Astronomy." The excursion was pronounced by 

 all who were present as an eminently successful and enjoyable 

 one.— H.M.A.
