Mr. Whiteaves, of our Club, gave a graphic description of the 

 geological structure of Lachute and its vicinity, vvhilst the writer was 

 called upon to read the results of the competition in geology. 



Casselman. — -On the 21st of June over 100 members and friends 

 of the Club visited Casselman, a favourite locality for all branches of 

 our Club's work, along the line of the Canada Atlantic Railway, and a 

 considerable amount of work w is done in the Tre?ifon and Quarternary 

 deposits there exhibited. Quite a list of Trenton fossils was obtained 

 and specimens of pottery and an arrow-head together with bones of the 

 beaver and other creatures were found close to where on previous occa- 

 sions numerous collections of Indian relics had been made. The old 

 aboriginal fire-place, in which debris of pottery, bones, charcoal, and 

 Indian remains were found, had been washed away by the high water 

 and spring floods. This locality is a most interesting one, and careful 

 research may reveal unexpected treasures in Ethnological studies. 



Hog's Back, Rockliffe, c^r.— The Chazy terrane which offers such 

 an interesting field for research about Ot awa, was visited, at Hog's 

 Back, in Nepean, and at Rocklifife, below Governor-General's Bay. 

 Interesting rocks and trails of marine animals, some of which are 

 perfectly new to science, and others resemble the Protichnites of Sir 

 Richard Owen described in the Quarterly Journal of the Geological 

 Society, London, from the Potsdam of Canada, were obtained and pre- 

 liminary studies of them have been made. 



The Trenton rocks ot Governor General's Bay, Moose Creek, 

 and the Beaver Meadow were also visited at sub-excursions and notes 

 taken at each of these localities as to the character of the rocks, dip of 

 the strata and fossil remains contained therein. 



Gloucester. — -The Utica terrane in the vicinity of the Rideau River 

 rapids opposite the Rifle Range in Gloucester was again visited. I 

 was fortunate enough in finding two more examples of the Turrilepas 

 Canade7isis, recently described by Dr. Woodward in the Geological 

 Magazine, and it is expected that these additional representatives of 

 that antique style of barnacle will through some light on the type speci- 

 men found at the same locality in 1888.

 excavations on Albert street in 1888 and in rocks of the same horizon
