ANCIENT WORKS AT LAKE SUPERIOR.

O. Vand3kc. Arrow-points were attaclied in the same way (see Fig. 34), as shown 

 by one found at Menasha, on Lake Winnebago, and received from Mr. Curtis Eeed. 



Copper Kuife from Lake Superior. (One half natural size.) 



In the immediate valley of the Mississippi the animal forms do not appear to be 

 as numerous as on the Wisconsin and in some other localities. So far as I can learn, 

 they extend down only as far as Apple river, in Illinois, a few miles south of the 

 State line of Wisconsin.

There are occasional localities south of the Wisconsin river, where traces of 

 ancient works can be seen ; but the immediate bank of the Mississippi is so broken 

 that it could not be explored without much labor and difficulty. 



The works at Prairie du Chien, heretofore described (page 66), are the most 

 extensive of any on the river; but these are too much injured to exhibit with dis- 

 tinctness their original forms. 



Along the great dividing ridge between the Mississippi and the Kickapoo rivers, 

 there are mounds in great numbers. Their general character is the same as that of 

 those near the residence of Mr. Miller (Plate LI), and they may, without much effort 

 of imagination, be classed among the birds and buffaloes, accompanied by oblong 

 and circular mounds. This ridge may be aptly compared to the back-bone of some 

 gigantic animal, the numerous lateral spurs, extending towards the Mississippi or 

 the Kickapoo, representing the ribs. 



The animal effigies along the ridge are usually headed towards the south or 

 southeast. The elevation is from four hundred to seven hundred feet above the 

 adjoining rivers. The arrangement of the strata of rock (as exhibited in the section, 

 Plate LI) is such as to cause numerous springs to gush out on either side, not far 

 below the summit ; and that circumstance may have led to the occupancy of the 

 ridge by so large a population, as is indicated by their works still remaining. It is 

 now inducing settlements in the same locality by a different race of men ; the prime 

 necessities of man being alike under all circumstances.
