'Concession 3, Rideau Front of Gloucester; Lot N, Concesi-ion A, Nepean ; at the 

 summit of the Chazy outcrop already referred to south-east of Green's Creek, 

 and at the quarries near Hog's Back, on the Gloucester side of the Kideau River. 



The formation next in order is the Trenton, and as most of the limestone in 

 the immediate vicinity of the City belongs to it there are many fossiliferous 

 localities that would repay careful attention, but only a fnw of the richest known 

 are mentioned. That at Barrack Hill, described in the Geology of Canada, 1863, 

 as most productive of new species, and from which was obtained the greater part 

 of the crinoids and cystids described in Decades 3 and 4, does not seem to be 

 accessible now, having probably been covered by debris from the excavations 

 for the Lover's Walk. 



Good fossiliferous localities, and ea«y of access, occur east of the steamboat 

 "landing on Sussex Street ; at McKay's Bay ; the quarry at Brigham's Lake, Hull 

 .(Crinoids) ; "Wright's quarry, Hull ; at the railway cutting immediately west of 

 the crossing of the Aylmer road (Monticuliporc'c) ; at the old lime kilns, Mount 

 Sherwood ; and above the Chaudiere Falls on the Hull side of the river, at low 

 water. 



Beds of the Utica formation, constituting the base of the Hudson River 

 group, and immediately overlying the Trenton, occur on the banks ot the Rideau 

 at the rifle range, at Cummings' Bridge, at a small creek between Cummiugs' and 

 Hurdman's Bridges, and in the brook above Billings' Bridge. Mr. Ami is 

 preparing for the Club a paper upon the fossils found by him in these beds. 



No formations more recent are known to exist near Ottawa until the post- 

 tertiary clays are reached, of which there are good fossiliferous localities below 

 Rockhffe on the south bank of the Ottawa, when the water is low ; at the mouth 

 of Green's Creek, and in the gravel beds at Gloucester station on the St. Lawrence 

 and Ottawa Railway. 



In conclusion it is hoped that a large number of members of the Club may 

 be induced to pursue this most attractive branch ot field work during the coming 

 season, particularly now that the headquarters of the Geological survey have 

 been brought to Ottawa, that the magnificent collection in its museum will 

 shortly be open for study and comparison, and that some of the officers of the 

 survey who are members of the Club may be induced to lead this branch with 

 the success that their high scientific attainments would ensure.

REPORT OF THE BOTANICAL BRANCH 



For the Season of i88i. 



To the Council of the Ottawa Field-Naturalists' Club: 



In making a report ot the work done in the Botanical Section during the 

 past year, your committee must first congratulate the Club on the progress made 

 in this branch and on the success that has attended the system inaugurated this 

 season. "VVe also take this opportunity to thank the members for their evident 

 ■desire to render our duties easy, and for the interest they have shown in the 

 work of the new system. 



Owing to the spring circular having been issued after the botanical season 

 had opened ; some who would have liked to commence work with the Club, for
