784. Channel opened by Erian drainage while the ice-sheet occupied the Ontario 



basin, between Syracuse and Jauiesville, New York. The channel is 

 traversed by the Delaware, Lackawanna and Western railroad; looking 

 west (No. 601). 



785. Channel opened by Erian drainage while the ice-sheet occupied the Ontario 



basin. Two miles southwest of Jamesville, New York (No. 604). 



786. Channel opened by Erian drainage while the ice-sheet occupied the Ontario 



basin. Three miles east of Marcellus village, New York ; looking east. 

 The upland through which the channel was eroded forms the skyline at 

 the right (No. 630). 



787. The Gulf. A channel opened by Erian drainage while the ice- sheet occu- 



pied the Ontario basin. Four miles west of Marcellus village; looking 

 east (No. 646). 



788. Channel opened by Erian drainage while the ice-sheet occupied the Ontario 



basin ; three miles west of Palmyra, New York ; looking west. The north 

 wall, composed of drift, forms the skyline at the right. Boulders washed

797. Section of anticlinal ridge in railway cut one mile east of Dunkirk, New 



York. The rock is a black shale of Devonian age. The anticlinal structure 

 was imposed after the retreat of the Pleistocene ice-sheet (No. 912). 



798. Shore of Lake Ontario, at Pillar point, New York. Removal of glacial de- 



posits by the waves has exposed a typical glaciated surface traversed by 

 a few scratches ascribed to the grounding of icebergs. Published by T. C. 

 Chamberlin, Seventh Annual Report U. S. Geol. Survey, page 166 (No. 915). 



799. Shore of lake Ontario at Pillar point, New York. The aberrant scratches
