CHAPTER V. MONUMENTS OF THE NORTH-WEST.

It has already been observed that the ancient monuments of the Southern United States, although partaking of the general character of those of the central region, are nevertheless in many respects peculiar. While enclosures are comparatively few, mounds are abundant and of great size and symmetry, and possess a regularity of arrangement which we look for in vain among the corresponding structures of a higher latitude. Proceeding to the North and North-west, we find the earthworks assuming a new form and character, in many respects so unlike those both of the central and southern divisions of the country, that we are almost induced to assign them a different origin. As at the South, there are few enclosures or works of defence; but, instead of regular pyramidal structures, the mounds generally assume the shape of animals, presenting a thousand singular forms and combinations. These effigies are situated upon the undulating prairies and level plains, and are accompanied by conical mounds and occasional lines of embankment; but the latter, except in a very few instances, have no obvious design, and enter into none of the combinations which we notice in the works of the Ohio valley. The interesting field occupied by these remains has not fallen within the range of the investigations of the authors, who are therefore unable to present much that is new respecting them; still, it will be necessary to embody the facts thus far disclosed in a general manner, in order to an adequate comprehension of the scope and character of our antiquities. And here, at the outset, we have again to regret the small amount of information respecting these works in possession of the public, as well as its unsatisfactory nature, resulting from the necessarily limited and disconnected observations of those who have paid any attention to the subject. These observations have been made by men of inquiring minds, in the scanty intervals of professional business, and are consequently too detached to justify or sustain any general conclusions. They have served rather to excite than to gratify curiosity, and in this way they may have the good effect of leading to a full and careful survey of the entire field.

The first public notice of the existence of these singular relics at the North-west, was made by RICHARD C. TAYLOR, Esq., in the “American Journal of Science and Art,” for the month of April, 1838. His paper, which was accompanied by several illustrations, attracted considerable attention, and was followed, in the same Journal for 1843, by a more extended account, very well illustrated, from the hand of S. TAYLOR, Esq. A later notice by Prof. JOHN LOCKE constituted a short chapter in the “Report on the Mineral Lands of the United p125 States,” presented to Congress in 1840 and published in 1844. These, with a few unsatisfactory notices in the public prints, comprise the only sources of information which we possess; and from them the following facts are mainly derived.

The field in which these remains occur, so far as observed by the above authorities, is embraced within the lower counties of Wisconsin, and extends from Prairie du Chien on the Mississippi, by the way of the Wisconsin and Rock rivers, eastward towards Fond du Lac on Lake Winnebago, and Milwaukie on Lake Michigan. The country thus indicated is about one hundred and fifty miles in length by fifty in width. The great Indian trail or “war path,” from Lake Michigan near Milwaukie to the Mississippi above Prairie du Chien, which has for the most part been adopted as the route of the United States military road, passes through this chain of earthworks. They are found in abundance by the sides of this great natural pathway, which has been for ages and must for ever remain the route of communication between the Great Lakes and the Great River. They occur principally in the vicinity of the large water-courses, observing in this respect a marked conformity with the remains of other sections, and are invariably placed above the influence of freshets or inundations. Like those of the Ohio valley, they are seldom found upon hilly or sterile lands, but mainly upon the rich undulating plains, or on the levels corresponding to the alluvions of the Ohio.

They consist of elevations of earth, of diversified outline and various size, for the most part constituting effigies of beasts, birds, reptiles, and of the human form; but often circular, quadrangular, and of oblong shape. The circular or conical tumuli differ from those scattered over the whole country in no outward respect, excepting that they are much smaller in their average dimensions; the largest seldom exceeding fifteen feet in height. Those in the form of parallelograms are sometimes upwards of five hundred feet in length, seldom less than one hundred; but in height they bear no proportion to their otherwise great dimensions, and may probably be better designated as walls, embankments, or terraces, than mounds. These works are seldom isolated, but generally occur in groups or ranges, sometimes, though not always, placed with apparent design in respect to each other. In these groups may be observed every variety of form,—the circular, quadrangular, and animal-shaped structures occurring in such connection with each other as to fully justify the belief that they are of contemporaneous origin. At first glance, these remains are said to resemble the sites or ground-plans and foundation-lines of buildings; and it is not until their entire outline is taken into view, that the impression of an effigy becomes decided. This is not surprising, in view of the fact that they are usually of inconsiderable height, varying from one to four feet; in a few cases, however, rising as high as six feet. Their outlines are, nevertheless, represented to be distinctly defined in all cases where they occupy favorable positions. Their small altitude should cause no doubt of the fidelity of the representations which have been made of these figures; since a regular elevation of six inches can be readily traced upon the level prairies and “bottom-lands” of the West, especially when it is covered with turf. The following illustrations, selected from those presented by the authorities above mentioned, will serve to explain the character of p126 these remains. It is to be regretted that explanatory sections do not accompany the plans, so as to exhibit, at one view, the altitude as well as general outlines and dimensions of the figures.
