ence of a fault in that locality, but in the trench cut along- Somer- 

 set street east between Chapel street and Goulborne avenue the 

 dislocation was clearly visible. Mineralization along- the line of 

 fault, as is customarily the case, had taken^place resulting in 

 the segreg-ation of a considerable quantity of calcite associated 

 with iron pyrites. 



This fault was seen to trend in an almost due east and west 

 direction heading for the western end of Sparks's rapids on the 

 Rideau river. On each side of the fault and in the neighbourhood 

 of the same the strata were strikingly dissimilar ; on the east side 

 thin bedded limestones with interstratified black bituminous shales 

 were exposed, whilst an almost compact and homogeneous mass 

 of fissile and black bituminous shales holding but few fossils, com- 

 pared with the lower beds of the series occurred on the east side 

 of the fault. 



Lists of the fossils noted during these sub-excursions were 

 prepared .and will accompany this report. They will serve to 

 emphasize the facts already noted of the existence at that point of 

 an upper and a lower outcrop of the beds of the Utica formation. 



New Edinburgh, — At the C. P. R. crossing along the DufTerin 

 road in New Edinburgh, the main drain excavations revealed fine 

 sections in the Utica formation also. On the occasion of the first 

 excursion of the Club to Beechwood (see p. 94 of the Trans, of 

 the O. F. N. C.) the geological section examined the exposures 

 as well as the dumps, and a large quantity of fossils were ob- 

 tained. Your leaders were kept busy identifying and determining 

 specimens from the time the excursionists reached the spot until 

 time was called to meet at the rendezvous near the Cemetery 

 gate, where the addresses were given on the finds of the day. 

 Seventeen species of fossils typical of the Utica were listed on that 

 occasion from specimens obtained by one or other of the following 

 persons present for whom they were named. Leaders : Dr. R. 

 Bell, Mr. W. J. Wilson, Dr. H. M. Ami; Members, &c.: Mr. 

 Clark, Mr. Kendall, Miss McQuestion, Miss Ross, Mr. Baldwin, 

 besides the following younger but enthusiastic collectors : Alex- 

 ander Anderson, Herbert Maingy, Lloyd Blackadar, Otis Whelen 

 and Gordon GuUock.
