ANCIENT MOUNDS.

The valley of the Mississippi and the valleys of its tributary streams abound with mounds of various sizes and fashions, circular, oval or oblong, serpentine and sometimes irregular in outline, and all works of intelligence and design, wrought by some ancient people for purposes now not fully known. It is probable, however, that some were used as places of defense, others were built for sacrificial or religious purposes, others for sepulture, and others still may be the remains of dwellings. Most of them contain relics, coins or implements made of shells, of flints and in some instances of baked earthenware, and lastly human remains. These relics are not necessarily of cotemporaneous date, and many of them are comparatively modern. Such mounds were used for burial places long after their original builders had passed away.

That they are very ancient is unquestionable. They outdate the traditions of the Indians who inhabited this country at the date of its discovery, while the most ancient remains taken from them indicate as their builders a people widely different from the present aborigines, and possessed of arts unknown to them. Conjecture points to a race from the South, probably the Aztecs, as the mound builders. This race was exterminated in some way, or driven away by some stronger tribes, who may in turn have given place to our present race of Indians. A full description of these ancient works would require volumes; we can therefore allude only to a few that may be considered typical specimens of their class.

At Prairie Village, now Waukesha, Wisconsin, in 1836, the writer saw a mound six feet high, representing a tortoise, the head, feet and tail being still distinctly traceable. Many mounds exist at Prairie du Chien, some quite large, and of varying shape, some representing inclosures or fortifications, with gateways or openings. These are located on the high bluffs east of the Prairie. Many of these, very distinct in the early days, are now almost obliterated by the plowshare of the farmer and the spade of the relic hunter.

The builders of the ancient mounds certainly exercised great taste in their location, as they are generally found in pleasant localities, on grassy plateaus or elevated lands, and by the shores of lakes and streams. Some, originally built on plains, have since been overgrown with trees. In some cases trees of immense size have been found growing even on the summit of the mounds. The most notable mounds of the St. Croix valley are at Vasa village, in Marine township, Washington county, Minnesota, and in the neighborhood of Osceola Mills, Polk county, Wisconsin. We append notes of a survey of the latter, made in 1870. They are sixteen in number and we mention only the most remarkable.

No. 1 is of circular form, 20 feet in height and 60 in diameter. Trees 2 feet in diameter are found on this mound. Mound No. 2 has a diameter of 90 feet, and was originally 30 feet high; at present but 20. This mound is also of circular formation. Mound No. 3 is circular in form, 36 feet in diameter and 2 feet high. Mound No. 4 is circular, 40 feet in diameter and 5 feet high. Mound No. 5 is oblong and 40×60 feet in dimensions, and 4 feet high. The largest and finest of these mounds have been nearly destroyed by the encroachments of the road makers. These mounds are located two miles north of Osceola, on Close creek. Alanson Thompson made a homestead of the land on which they are situated, and built his home immediately in the rear of the two larger mounds. His garden included many of the mounds.

Mr. T. H. Lewis, of St. Paul, made a later survey of these ancient mounds. In the group north of the creek and near the school house, which he classifies as the upper group, he finds ninety-six well developed mounds, and some of them of peculiar shape and great interest. In the group south of the creek, which he calls the lower group, he finds forty-nine mounds, a total of one hundred and forty-five in the two groups; at least five times as many as has been supposed to be there.

But one of the mounds is an effigy mound, and this is not clearly defined, plowing in the field having disturbed the outline of the effigy. The most of them contain bones, as has long been known, and Mr. Lewis finds in them shell relics, which are rarely found in any mounds; also pottery, and beads made from shells.

Another peculiar mound not included in this description may be found on the bluff overlooking the St. Croix, not far from the Close creek series of mounds. It is over one hundred feet in length and serpentine in form, one end being enlarged to represent the head. There are also fine specimens of ancient mounds on Chisago lake, near Centre City and Chisago City.

The subject is a fascinating one to the archaeologist, but it behooves him to make haste with his investigations, as these marvelous works are rapidly disappearing, being dug over by the irresponsible and unscientific relic hunter, or worn down by the plow, or carted away for loose earth to mend a roadway or fill a sinkhole.
