Introduction. 



It is designed in this paper to describe the character and distribution 

 of those deposits in the Chenango valley which ow r e vheir form and struc- 

 ture, wholly or in part, to the waters of the melting glacier. Theoretic 

 considerations will have but a limited place, and especially must any 

 adequate reading of the glacial history of the region await the detailed 

 stud}^ of parallel areas on the east and west. The upper course of Oris- 

 kany creek on the north is included in the study, the common valley of 

 the divide near Bouckville being as spacious as farther down on either 

 stream. The position of the water-parting is determined within certain 

 limits by the disposition of the glacial flood materials. The neighbor- 

 ing cols at Pratts, Waterville, and Cassville are of a similar nature. 

 Thence the north-flowing streams pass, by short, sharp descent, to the
