These reports describe the glacial deposits, 'lake beaches, soils, and ]jre-Pleistocene geology, and give consid- 

 erable attention to drumlins, which are said to have been chiefly formed by the sculpturing of a drift sheet that 

 was overridden by the ice. Illustrated by several good photographs.

Reviews explorations by Marquette, Joliet, La Salle, Hennepin, La Hontan, Charlevoix, Alexander Henry, 

 Carver, Hearne, and McKenzie in the Great Lakes region and the country to the .north. Describes with much 

 accuracy the shore features of Lake St. Clair, St. Clair River, west side of Lake Huron, both sides of Lake Michi- 

 gan, and part of the south shore of Lake Superior, calling attention to the small extent of the rock outcrops and 

 the universal presence of granitic and hornblendic rocks even on high points like Mackinac Island. Notes buried 

 timber between sand deposits and blue clay near the head of St. Clair River, and remarks that the drift deposits 

 or alluvium may be composed of several distinct formations.
