Three miles from Rome the channel blends into the broad, 

 smooth plain which forms here the divide between Hudson and 

 St Lawrence waters. The banks which constitute the south wall 

 curve around the high ground 2 miles south of Rome and end 

 at Stanwix village. These banks were cut by river flow preced- 

 ing the inception of Lake Iroquois, at a time when the ice sheet 

 still occupied the divide. A strong and conspicuous bluff behind 

 the village, with altitude by the map contours of about 460 feet, 

 tells the fact of the early drainage. 



The interval between Rome and Stanwix, about 2 miles, 

 has been swept and leveled by river action. The line of water 

 parting has about the course of the canal and the New York, 

 Ontario and Western Railroad, with altitude of 430 feet. For 

 ages here was the outlet of the great Lake Iroquois and the head 

 of the great river which was predecessor to the St Lawrence. 



Relation of these low channels to the high channels 



To appreciate the supposed relationship between the channels 

 described in this paper and the channels on the higher ground, 

 the reader should have in hand, for comparison with the maps 

 (pi. 7-10) accompanying this paper, plates 15 and 16 in the former 

 report. 



The study of the relation between the high and low channels, 

 in both location and altitude, leads to the following tentative 

 conclusions. (1) The waters which cut the high channels across 

 the points of Eaton, West Stockbridge, Oranson and Eagle hills 1 

 found eastward escape by several channels higher than the 

 Verona-Greenway channels, and lying on the ground west and 

 north west of Clinton. At that time the lower ground of the 

 Verona-Greenway channels was yet buried under the ice 

 sheet. (2) The Round Lake and Mycenae channels, northeast 

 of Fayetteville 2 probably correlate with the channels described 

 in this paper as lying between Chittenango and Canastota. 

 This series should also include the channels south of Fayette- 

 ville and west of Manlius, and probably the earlier cutting of
