apology is the statement that much greater opporttmity for study 

 of the region has given superior advantage. The greater part of 

 the field work was done before Leverett's descriptions and maps 

 appeared, but these have been suggestive and helpful and have 

 caused reexamination of some districts. In the belt of stream chan- 

 nels and lake beaches nearly every highway has been traveled, many 

 in both directions, and many features have been examined from 

 different viewpoints. Some districts have been visited several 

 times, yet there is a mass of interesting detail almost untouched, 

 which possibly has entailed some minor errors in fact or interpreta- 

 tion in the paper. A resident in almost any portion of the area 

 can find, after training his eye and mind to see and understand 

 them, many other interesting features resulting from the work of 

 the glacier or the glacial waters. The writer has satisfaction in the 

 thought that many people living in the area described will find a new 

 source of pleasure in having their attention directed to these ro- 

 mantic geologic phenomena. 



LITERATURE 



Very little systematic work on the phenomena of glacial waters in 

 the New York portion of Lake Erie basin has been done except by 

 Mr Frank Leverett, although the beaches have long been recog- 

 nized. In Leverett's Monograph XLI he gives on pages 28-49 a 

 full list of works which contain any reference to the glacial geology 

 of the region. It is not desirable to repeat that list here, but a few 

 writings which have more immediate reference to the New York 

 area are noted below.
