The growing interest in the evolution of the Continent now calls for more accurate information than formerly regarding the changes of level of land and sea in recent geological times. The amount of these oscillations was one of the most important factors in the investigation of the “Building of the Great Lakes.” Hence the study of the history of the lakes has contributed to our knowledge of the changing relations of the continent and the sea.
