INTKODUCTION. 3 



York, extending tilong the eastern sliore of Green Bay, and tlience, in the same 

 general direction, through Brown, Calumet, Fond-du-Lac, and the eastern part of 

 Dodge counties. It constitutes the clifls along the east side of Lake Winnebago ; 

 and interrupts the flow of the rivers west of it in their course towards Lake Michigan, 

 turning them northward into Green Bay. Fi'om its crest another system of rivers 

 originates, which, running in the same general direction, flow into Lake Michigan. 

 Immediately west of this bold escarpment commences a remarkable series of ridges, 

 probably caused by "drift" agencies (whatever they may have been), and of which 

 some notice will be found in the following pages.^ 



The moderate elevations, and the gentle declivities of the several valleys, cause 

 the waters to flow in slow and uniform currents, and to assume, in very numerous 

 instances, the form of lakes of greater or less extent. It is precisely such localities 

 that afford the greatest facilities for Indian population. During the hunting sea-' 

 son, the wild man roams over the vast forests and prairies; but his village is 

 always established near some lake or gently flowing river, abounding in fish and 

 wild rice, and affording him a subsistence, either directly or indirectly, by enticing 

 within his reach innumerable animals that seek their food at the same place.
