Indian Mounds and Earthworks. 93 
front of this bluff, and enclosing the mound or efligy, is a long 
earthwork in an exact straight line, about two hundred yards in 
length, having an opening in the centre opposite to the animal. 
The position of this earthwork indicates its having been designed 
for the purposes of defence or fortification against an enemy ; 
perhaps as an outwork to the strong hold in the rear, formed by 
the bluff itself. The great Indian road to which we have already 
referred, skirts along the outer or southern side of this embank- 
ment. 
Fig. 4, Pl. nm. This sketch is drawn from the admeasurement 
of acouple of animal-shaped mounds, between which passes the 
same Indian path, at the distance of six miles west of the Four 
Lakes. These figures are selected to shew that one, if not both 
of them, represented a different species of animal to those we 
have traced in the preceding outlines. In one instance only they 
were depicted with the appendage of a tail; the others were tail- 
less ; and whether in the present case this deviation from the 
usual configuration resulted from the caprice of the Indian artists, 
or really depictured some beast more favored by nature than his 
contemporaries, it is not easy at this period to decide. ‘They are 
respectively one hundred and twenty and one hundred and two 
feet long, and perhaps may have been intended to.represent foxes.

of the ~ of that name, in the region still held by the Winne- 
innumerable: mounds, both of the circular and most 
of the ae forms we have figured. At one position, however, 
near the river, and not far from English prairie, a group of six 
of these appear to represent birds, probably the eagle, or perhaps 
the crane, which was the ancient badge of the chiefs of a branch 
of the once powerful tribe of Chippewas.* This sketch was 
icated to the writer by the person who took the original 
admeasurements The scale of these is about the same as the
