To Dr. Frank Leverett and to the NLemory of 

 Mr. Frank B. Taylor: 



Through nearly half a century Dr. Leverett and Mr. Taylor 

 explored and deciphered the records made by the continental 

 glaciers during the Ice Age. Front their studies was revealed 

 the fascinating history of the Great Lakes. They travelled, 

 mainly on foot, thousands of miles along the glacial moraines 

 and over the beaches, shores and beds of the ancient lakes, 

 measuring, recording and mapping as they went. They em- 

 bodied their observations and conclusions in many scientific 

 publications. Their ivork and their lives have been an inspira- 

 tion to other geologists who have folloived their footsteps and 

 to many students ivho absorbed, in their lecture halls, the 

 interesting story of glaciation. Much of this tale — NE-SAW- 

 JE-WON, of ^^the waters that run down from Lake Superior 

 to the sea'' — is draivn from their classic volume, ''The 

 Pleistocene of Michigan and Indiana and the History of the 

 Great Lakes'' and from Dr. Leverett' s ''Moraines and Shore 

 Lines of the Lake Superior Region" — publications of the 

 United States Geological Survey.
