■changes of the Southern portion of the Ontario Shore near 

 Winona, where the Lake is rapidly encroaching on the land. 

 As far as I know, no Field Geologist has noted the sub-aerial 

 changes taking place in the Niagara Escarpment here, and its 

 recession at several points, despite the protection afforded by 

 the vegetation, grasses, etc. when the rocks were laid bare and 

 exposed as the glacier retreated. This must have been a pow- 

 erful agent in land, and rock degradation, and its agency was 

 probably sufficient to remove the entire face of the Escarp- 

 ment. For even since the small reservoir was excavated, 

 almost annually, tons of material which fall from the Clinton 

 Series above it are removed by the city. I regret Dr. Pettit, 

 of Grimsby, was laid up by illness last summer and unable to 

 point out the place in the ravine where he had noticed "Gla- 

 cial Scratches," etc., on the face of the clififs corresponding to 

 its axis. 



ORGANIC REMAINS. 



The Barton Niagaras during the past collecting season 

 afforded no new species, but some fine slabs were obtained 

 from "The Waterlime Beds" above "The Albion Mills," con- 

 taining apparently Plant Remains, alluded to in our local cata- 

 logue, "Niagara Fossils." Specimens were forwarded "The 

 Redpath Museum, Montreal," and furnished to Dr. Ami, 

 F.G.S., Canadian Geological Survey, Assist. Palaeontologist, on 

 his recent visit to Hamilton. The base of the Barton Shale, 

 near the City Drain, resting on the chert, afforded me a fine 

 Brachiopod Rhynchonella Tennesseensis Roemer. Dr. Hall 

 found one and gave it the same name, which slightly differs, a 

 variety perhaps. He renames it "Uncenulas Stricklandi." It 

 may be. It would be necessary to obtain both originals for 

 comparison to be certain as to which it belongs. 



The Niagara Chert, as usual, displayed some "New Grap- 

 tolites," and the Glaciated Flint Flakes (Chert) in the field, 

 close to "^the Corporation Drain," presented a few "Bryo- 

 zoons," "Fenestelledge," and "Cladoporse." A small parcel of 

 the latter was given to Prof. Ami, who remarked, on one of
