92 Indian Mounds and Earthworks. 
There is nothing remarkable about the oblong mounds. The 
circular tumulus in the centre is the highest, and overlooks the 
whole group. Whether all or any.of these earthworks contain 
bones, we had no opportunity of determining. ‘They probably 
all do. 
The site of this interesting series is an ‘elevated open prairie, 
on the dividing ridge between the waters of the Wisconsin and 
Rock rivers. "These monuments are covered with the same green 
carpet of prairie grass, intermixed with bright and brilliant flow- 
ers, as the prairie itself. There is an intervening space near the 
centre of the group, now overgrown with bushes, which probably 
conceal some unnoticed mounds. The figures marked on these 
and the other animal outlines in our drawings, indicate their di- 
mensions in feet. 
We twice visited these singular specimens of Indian antiquity, 
and consequently can speak with greater confidence as to the gen- 
eral accuracy of the sketch accompanying this article. 
Half a mile westward of this remarkable group, and on the 
same elevated prairie, occurs a solitary mound, about ninety feet 
in length, representing an animal in all respects like those we 
have described, but lying with the head ee the southwest.

Along the space of twenty miles from this position, extending 
to the Four Lakes eastward, similar monuments, intermixed with 
plain tumuli, are seen at almost every mile, in the lowest situa- 
tions as well as crowning the highest swells of the prairies; and 
they are still more numerous all around those beautiful but almost 
unknown lakes. It would be a ceaseless repetition of similar 
forms were we to figure many of these, but the outlines of a few 
of the most characteristic are introduced in the plate. Had time 
and circumstances permitted a more leisurely investigation and 
survey of some of the groups of this region, there is little doubt 
but many drawings of a highly interesting character could have 
been constructed in addition to those which illustrate this com- 
munication. 
_ Fig. 3, Pl... An effigy ninety feet long, in form resembling 
animal outlines previously described, is placed nearly at the 
foot and at the point of a remarkable, picturesque, perpendicular 
bluff, of coarse, friable sandstone, fronting a rich meadow, the 
favorite resort, no doubt, of numerous buffalos in olden times. In
