Introduction. 



The study of the hicustrine history of tlie Genesee valley was under- 

 taken in continuation of the work upon the glacial lakes in western New 

 York* and with no expectation of making it the subject of a separate 

 paper. The history is found, however, to be of remarkable and romantic 

 character. The glacial waters alternately flowed to the gulf of Mexico 

 and to the Atlantic ocean direct. Five great river S3\stems received the 

 overflow at diff'erent periods, namely, Ohio-^Iississii)pi, Susquehanna, 

 Illinois-Mississippi, Hudson, and Saint Lawrence.
