34 PLEISTOCENE OF INDIANA AND MICHIGAN. 



Bell, Robert. On glacial phenomena in Canada: Bull. Geol. Soc. America, vol. 1, 1890, pp. 287-310. 

 Summarizes results down to 1890 and touches on history of Great Lakes. 



Postglacial outlet of the Great Lakes through Lake Nipissing and the Mattawa River: Bull. Geol. Soc. America, 



vol. 4, 1893, pp. 425-427. 

 Doubts if the Mattawa Valley is capacious enough to have served as such an outlet. 



Proofs of the rising of the land around Hudson Bay: Am. Jour. Sci., 4th ser., vol. 1, 1896, pp. 219-228. Also 



in Ann. Rept. Smithsonian Inst, for 1897, pp. 359-367. 



Cites evidences in support of view that a rise of 7 to 10 feet per century is in progress. See Tyrrell, J. B., for 

 opposing evidence. 



Evidence of northeasterly differential rising of the land along Bell River (Canada): Bull. Geol. Soc. America, 



vol. 8, 1897, pp. 241-250. 

 Character of drainage is thought to indicate that an earth movement is in progress. 



The geological history of Lake Superior: Trans. Canadian Inst., vol. 6, 1899, pp. 45-60. 



Thinks from the occurrence of Cretaceous rocks to the west that the Lake Superior basin may not have had 

 vigorous excavation until the Tertiary period. Inclines to view that ice greatly accentuated stream erosion and 

 that warping is likely to have aided in producing the basin of Lake Superior. Thinks preglacial outlet of Lake 

 Ontario was through the Mohawk; that of the Erie and Huron westward from Lake Erie into the Mississippi; that 

 of Lake Michigan southward; and that of Lake Superior perhaps via Lake Nipigon northeastward, perhaps through 

 a river across site of Hudson Bay. Refers to Au Train outlet southward as possible. Reviews the literature to 

 some extent.

 Bennett, L. F., Headwaters of Salt Creek in Porter County, Ind.: Proc. Indiana Acad. Sci. for 1899, pp. 164-166. 



Describes knolls and marshy tracts in a moraine at the head of the creek. 

 Bigsby, J. J., Geological and mineralogical investigations in the northwest portion of Lake Huron: Am. Jour. Sci., 

 vol. 3, 1821, pp. 254-272. 



Mentions ancient beaches about Lake Huron and refers their formation to ocean water. Mentions marine fishes 

 in the waters of the Laurentian lakes above Niagara. , 



Notes on the geography and geology of Lake Huron: Trans. Geol. Soc. London, 2d ser., vol. 1, 1824, pp. 175-210. 



Discusses the transportation of the primitive rocks southward into areas of secondary rocks by the violent action 

 of floating substances rushing from the north. Recognizes the abraded surface of the primitive rocks. Briefly 

 discusses the effect of ice in transporting stones along the rivers and the effect of wind in heaping up the waters of 

 the lake on the leeward coast. 



On the erratics of Canada: Quart. Jour. Geol. Soc. London, vol. 7, 1851, pp. 215-238. 



Describes loose detritus and ancient beaches on the north shore of Lake Superior and about the lower Lauren- 

 tian lakes, giving altitudes of some of the beaches. Notes that both marine and fresh-water fossils occur near 

 together in deposits on the border of the St. Lawrence Valley. Gives diagrams of levels of fresh-water and 

 marine deposits and suggests origin of the raised beaches.

Discusses Pleistocene geology, including beaches of Lake Chicago. 

 — Geologic distribution of road materials of Indiana: Thirtieth Ann. Rept. Dept. Geology and Nat. Res. Indiana, 

 1905, pp. 120-132. 



Discusses the distribution of glacial deposits, stream deposits of all classes, and rock formations, and gives special 

 attention to the distribution of gravel and bowlders.

Indiana, 1905, pp. 878-880, 889-890, 896-S98, 934-936. 



Finds only a small area of glacial material in the counties discussed; treats this and the stream deposits and 

 also conglomerates of preglacial age.
