Part 3

No. 3, though the largest of the group, was apparently unstratified, the original burial consisting of the bones of two adults and one infant, at the original surface of the ground, under a thin layer of ashes, and surrounded by a single circle of small red stones. With these were found copper axes, copper beads, two carved stone pipes (one in the form of a ground-hog), animal teeth, etc. Near the surface of the mound were two well-preserved skeletons, with evidences of an "oakwood" covering over them and accompanied by glass beads, a fire steel, clay pipe, and silver ear-ring--evidently an intrusive burial.

No. 4 was found similar in construction and in all other respects to No. 3, except that at the feet of the skeletons was a round heap of stones, 3 feet high, neatly laid up, and that in the earth where the skeletons lay could be distinctly seen traces of cloth or some woven material, in which they had probably been enveloped.

No. 5 was similar to No. 2, except in the following respects: The skeletons (probably two) were in a confused heap at the bottom under a 6-inch layer of hard clay (probably similar to what Colonel Norris calls "mortar"). Near these, but outside of the clay layer, was a stone heap similar to that in No. 4. "On this lay two very strong thigh bones and three ribs placed diagonally across each other. There were also a few bones leaning against the heap at one side. The stones were partly burned to lime, and all of them showed more or less marks of fire, while the bones in the mound showed not the slightest trace of it."

Four or five feet south of the stone heap was a large quantity of human bones in complete confusion. The relics were broken pots, arrow-heads, a stone pipe, etc.

Nos. 7, 8, and 9 were similar to No. 1, varying only in minor details.[14]

My object in noticing the construction of so many mounds in a single group and the modes of burial in them, is to call attention to the differences in detail where there can be no doubt that they were built by one tribe and probably by one clan, as the size of the group indicates a comparatively limited population. In these nine mounds we notice the following differences: some are stratified, others not; in some the skeletons are placed horizontally on the ground, in others they are in a sitting posture, while in others they are dismembered and in confused heaps; in some there are altar-like[15] structures of stone which are wanting in others; in some the skeletons are covered with a hard clay or mortar coating which is wanting in most of them, and lastly, we see in one or two, evidences of the use of fire in the burial ceremonies, though not found in the others.

In some respects these mounds remind us of some of the stratified tumuli of Wisconsin, especially those opened by Colonel Norris in Sheboygan County, to which they bear a strong resemblance.

In the latter part of 1882 Colonel Norris examined a group of works in Allamakee County, Iowa, which presents some peculiarities worthy of notice in this connection.

This group, which is represented in Plate I, consisting of enclosures, lines of small mounds, and excavations, is situated on the farm of Mr. H. P. Lane, about 7 miles above New Albin. It is on a bluff in one of the numerous bends of the Little Iowa River, the character of the locality indicating that it was selected as one easily defended. I shall at present only notice those particulars which seem to have some bearing on the character of the burial mounds and mode of interment.

Although there are no effigy mounds in the group, the relative positions and forms of the tumuli, as shown in the figure, and other particulars to be noticed, leave no doubt in my mind that the works, in part, are to be attributed to the people who built the figure mounds of Wisconsin. But, as will be seen from the particulars mentioned, there is conclusive evidence that the locality has been occupied at different times by at least two distinct tribes or peoples, differing widely in habits and customs.

The largest work is an enclosure marked _A_ in Plate I, and shown on an enlarged scale in Plate II. It is situated on the margin of a bluff overlooking the Little Iowa and an intervening bog-bayou, probably the former channel of the river. It is almost exactly circular, the curve being broken on the east side, where it touches the brink of the bluff, being here made to conform to the line of the latter, though probably never thrown up to the same height as the other portion. The ends at the southeast overlap each other for a short distance, leaving at this point an entrance way, the only one to the enclosure. A ditch runs round on the inside from the entrance on the south to where the wall strikes the bluff on the north, but is wanting along the bluff and overlapping portion. The north and south diameter, measuring from outside to outside, is 277 feet; from east to west, 235 feet; the entire outer circumference is 807 feet, the length of the portion along the bluff 100 feet, and of the overlapping portion at the entrance 45 feet. The wall is quite uniform in size, about 4 feet high and from 25 to 27 in width, except along the bluff, where it is scarcely apparent; the entrance is 16 feet wide, and the ditch 5 to 6 feet wide and 3 feet deep. On the north, adjoining the wall on the outside and extending along it for about 100 feet, is an excavation (_c_, Plate II) 35 feet wide at the widest point and 3 feet deep.

As this ground, including the circle, has been under cultivation for fifteen years, it would be supposed the height of the wall is considerably less than it originally was, but this is probably a mistake. On the contrary, it was originally probably but 20 feet wide and not more than 3 feet high, composed mainly of yellowish brown clay obtained, in part at least, from the ditch, but during occupancy the accumulation of countless bones of animals used as food, stone chips, river shells, broken pottery, and dirt, and, since abandonment, the accumulation of sand drifted by the winds from the crumbling sandstone butte (_C_, Plate I) overlooking it, have not only filled the ditch but elevated the wall and whole interior area 2 feet or more. This accumulation of sand is so great and so uniform over the plateau that fifteen years of cultivation have not sufficed to reach the clay of the original surface nor to unearth or even penetrate to the bones, pottery fragments, and other refuse matter covering the original surface in the circle.

Trenches cut across the wall at various points indicate, first, a layer of sand about 1 foot thick; immediately below this an accumulation of refuse matter forming a layer from 1 to 2 feet thick; under which was the original clay embankment 2 feet thick, resting on the natural surface of the ground. A section of the ditch, embankment, and excavation is shown in Plate II. The dotted line _a b_ indicates the natural surface; No. 1 the original clay layer of the wall; No. 2 the layer of earth and refuse material with which the ditch is filled; and No. 3 the top layer of sand.

In No. 2 were found charcoal, ashes, fragments of pottery, fractured bones, etc.

A broad belt of the inner area on the east side was explored, and the same conditions were found to exist here as were revealed by the trenches across the wall and ditch, except that here the shells were more abundant in layer No. 2, and there were many burnt stones.

On the southeastern portion of the plateau (_B_, Plate I) are six nearly parallel lines of mounds running northeast and southwest, mostly circular in form, varying from 15 to 40 feet in diameter, and from 2 to 6 feet in height; a few, as indicated in the figure, are oblong, varying in length from 50 to 100 feet. The number in the group exceeds one hundred.

While engaged in excavating these mounds Colonel Norris observed a number of patches of the level area quite destitute of vegetation. The owner of the land, who was present, could give no explanation of this phenomenon, simply remarking that they had always been so, never having produced a good crop of anything, although there was no apparent difference between the soil of these spots and the surface around them. As some of these extended across the area occupied by the mound group, he concluded to explore them, and was surprised to find them to be burying places, and scattered here and there among the graves, if such they could be called, were stone chips, shells, charcoal, and ashes. He was surprised at this, as he supposed the mounds alone were used as depositories of the dead, and was at first disposed to attribute these burials to a people who had occupied the ground long subsequent to the authors of the works. Possibly this may be the correct solution, but if so, they were certainly the same as those who buried in the mounds of this group, as no difference in the contents and internal arrangement could be observed. In both cases there was a compact layer of hard, light-colored earth, having the appearance of lime-mortar, possibly clay and ashes mixed together, which had been subject to the action of fire. As the burials in these sterile spots were seldom more than 18 inches deep, the only layer above them consisted of sand from the butte, while the mounds were uniformly covered with a layer of richer soil, although below this and covering the skeletons was a layer of hard, light-colored earth. Skeletons and bones were found in great abundance in the mounds and under the surface of the plateau, though none were discovered in the circle or nearer than 200 yards of it. They were sometimes mingled promiscuously with charcoal and ashes, but were usually in whole skeletons lying horizontally, though some were in a sitting posture; they were within from 1 to 3 feet of the surface, without any apparent system, except that they were always covered with a layer of hard earth.

A trench cut through the long mound of this group, No. 1, revealed near the center an oblong pile of sandstones, beneath which was found a rude stone coffin, formed by first placing flat sandstone slabs on the natural surface of the ground, then other slabs at the sides and ends, and a covering of similar stones, thus forming a cist or coffin about 6 feet long and 18 inches wide. Within this, extended at full length, with the head west, was the skeleton of an adult, but too much decayed for preservation. With it were some stone chips, rude stone scrapers, a _Unio_ shell, and some fragments of pottery similar to those dug up in the circular enclosure.

The mounds on the sand butte marked _C_, Plate I, which is something over 100 feet high, were opened and found to be in every respect similar to those already mentioned, showing them to be the work of the same people who built the others.

The three mounds in the square enclosures marked _D_, (Plate I), were also opened, with the following results: The largest, oval in form, 30 feet long, about 20 feet broad and 4 feet high, was found to consist of a top layer of loose sand 1 foot thick, the remainder of hard yellowish clay. In the latter were found several flat sandstone fragments, and beneath them, on the original surface of the ground, a much decayed skeleton, with which were a few stone chips, _Unio_ shells, and fragments of pottery.

The second in size, 18 feet in diameter and 3 feet high, although covered with a layer of sand, was mainly a loose cairn of sandstones, covering traces of human bones, charcoal, and ashes. The third was found to be similar to the second, but in this case the pile of stones was heaped over a mass of charred human bones, mingled with which were charcoal, ashes, and fragments of pottery.

Fragments of pottery were found in abundance in the circle, in the mounds, in the washouts, and in fact at almost every point in the area covered by the group. Judging by the fragments, for not a single entire vessel was obtained, the prevailing forms were the ordinary earthen pot with ears, and a flask or gourd-shaped vase with a rather broad and short neck, often furnished with a lid. The paste with which this pottery was made had evidently been mixed with pounded shells. The only ornamentation observed consisted in the varied forms given the handles or ears and indentations and scratched lines.

Nearly all the implements found were of stone, exceedingly rude, being little else than stone flakes with one sharp edge; many of them having been resharpened and used as knives, scrapers, and skinners. Some had been worked into moderately fair perforators or drills for making holes in horn, bone, and shell--specimens of all these, with such holes, having been found here.

The immense quantity of charred and fractured bones, not only of fish, birds, and the smaller quadrupeds, such as the rabbit and the fox, but also of the bear, wolf, elk, deer, and buffalo, shows that the occupants of this place lived chiefly by the chase, and hence must have used the bow and arrow and spear; yet, strange to say, although careful search was made for them, less than a dozen arrow and spear heads were found, and these so rude as scarcely to deserve the name. A single true chipped celt, three sandstones with mortar-shaped cavities, and a few mullers or stones used for grinding were obtained; also, some fragments of deer-horn, evidently cut round by some rude implement and then broken off, and several horn and bone punches and awls, one barbed and another with a hole through the larger end.

The object in view in presenting these details is to give the reader an opportunity of judging for himself in reference to some inferences drawn from them.

The form of the circular enclosure reminds us at the first glance of the palisade enclosures figured by De Bry,[16] which, according to Lafitau,[17] was the form usually adopted by the Indian tribes who were accustomed to erect such structures. We have here the almost exact circle, save where interrupted by the margin of the bluff, the overlapping of the ends, and the narrow entrance-way. We have here also the clay with which it was the custom, at least in the southern section, to plaster the palisades or which was cast against their bases as a means of supporting or bracing them at the bottom, a custom not entirely unknown among the northern tribes in former times.

The indications are therefore very strong that this enclosing wall was originally a palisade which had been in part plastered with clay, or against which clay had been heaped to assist in rendering it firm and secure, and, if so, then it is probable it was built by Indians.

Be this supposition right or wrong the evidence is conclusive that the area on which this group is situated has been the abode of at least two tribes or peoples: first, it was occupied by the authors of the enclosures, whose stay was probably not very protracted, and after they had abandoned the locality or been driven from it by a second tribe, evidently comparatively numerous, that made it for a long time a dwelling place; a tribe differing in customs from its predecessor, and one that did not rely upon enclosures for protection. By no other supposition can we account for the fact that the refuse layer which covers the interior of the circle also spreads in equal depth over the ditch and clay remains of the enclosing wall, as those who left this refuse layer could have made no possible use of the wall as a defensive work, for which the position chosen and other particulars show it was designed.

The form of this enclosure, as we have before intimated, seems to connect it with some one of the Indian tribes; its age is uncertain but the accumulation of refuse matter and sand since the abandonment by the first occupants indicates considerable antiquity.

Although we cannot say positively that the second occupants were the builders of the mounds, as the investigation was not as thorough as it should have been, still I think we may assume, with almost absolute certainty, that such was the fact. The mounds in the square work marked D, in Plate I, present considerable differences from those in the group, and are probably the work of those who built the enclosures.

The stone grave in the oblong mound indicates the presence of individuals of a more southern tribe[18] at this place, during its second occupancy. The position of the cist in the mound would seem to forbid the idea of an intrusive burial, otherwise I should certainly suppose such to be the fact. I cannot, in the present paper, enter into a discussion of the question "to what tribe or people are the box-form stone graves to be attributed," but will state my conviction to be, after a somewhat careful study of the question, that they are to be ascribed to the Shawnees, Delawares, and Kickapoos.

Without further discussion of this group, which, as before intimated, presents, so far as the mounds are concerned, some features which appear to ally the latter to one class of burial mounds found in Wisconsin, we will now refer to some other works of this district explored by the Bureau assistants.

On the land owned by Mr. Fish, in Iowa, near the Mississippi River, a short distance below where the Little Iowa joins it, is a group of mounds placed on the crest of a ridge running parallel with the former stream about one-fourth of a mile therefrom. There are in all about thirty of these mounds, circular in form, and varying from 20 to 40 feet in diameter. These are all burial mounds, but one singular feature observed is that those on the higher sandy ground, although about the same size and having cores of clay similar to those on the firm clay portion of the ridge, have a layer of sand, some two feet or more added to them, yet when opened the contents and mode of construction of the two classes were found to be the same, to wit, a layer of hard clay covering decaying human bones, fragments of pottery, and rude stone implements. There were generally two or more skeletons in a mound, which were placed horizontally side by side on the natural surface of the ground.

Upon the terrace below the group were found the remnants of a row of comparatively large burial mounds. A railroad line having been carried along here, the larger portion of these works were destroyed; still, enough remained to show that the height varied from 6 to 15 feet, that they were composed chiefly of sandy loam similar to that around them, and that each had a hard central core of clay mixed with ashes, usually covering but a single skeleton. The relics found in them when opened consisted chiefly of stone axes, arrow and spear heads, and a few copper celts. In one, which was 32 feet in diameter and 8 feet high and less injured than the others, was a circular vault, walled as represented in Fig. 8. This was built of flat, unworked stones, laid up without mortar, gradually lessening as it ascended, and covered at the top by a single flat stone. In it was a single skeleton in a squatting posture, with which was a small earthen vase of globular form.

A singular fact was observed in a group near the town of Peru, Dubuque County. This group is situated on a dry, sandy bench or terrace some 20 feet or more above a bayou which, makes out from the Mississippi. It consists chiefly of small circular tumuli, but at the north end are four oblong mounds varying in length from 40 to 110 feet and in height from 1-1/2 to 4 feet; there is also an excavation about 30 feet in diameter and 6 feet deep, and scattered throughout the group are a number of circular earthen rings varying in diameter from 12 to 30 feet and from 1 to 2 feet in height.

Quite a number of the circular mounds were opened, but only detached portions of a skeleton were found in any one, as a skull in one, and a leg, arm, or other part in another, four or five adjacent ones apparently together containing the equivalents of an entire skeleton. Some of these bones were charred, and all were much decayed, indicating by their appearance great age. The inner portion of the mounds consisted of hard, compact earth, chiefly clay, resembling in this respect most of the burial mounds of this region.

Unfortunately the examination of this group was too partial and too hastily made to enable us to form any theory as to the meaning of this singular mode of burial, or even to be satisfied that the idea of our assistant in this regard is correct.

As possibly having some bearing upon the question, the following facts relating to another similar group at Eagle Point, three miles above Dubuque, are given.

This group, which is situated on a bluff about 50 feet above high-water mark, consists of about seventy mounds, all of which, except two oblong ones, are small and conical in form. Eleven of these circular tumuli were thoroughly explored, but nothing was found in them except some charcoal, stone chips, and fragments of pottery. But in an excavation made in the center of a long mound just west of the group were found two decayed skeletons. Near the breast of one of them were a blue stone gorget and five rude stone scrapers; with the other, thirty-one fresh-water pearls, perforated and used as beads. Excavations were made in an oblong and circular mound near the extreme point of the bluffs. Each was found to have a central core of very hard clay mixed with ashes, so hard in fact that it could only be broken up with the pick, when it crumbled like dry lime mortar, and was found to be traversed throughout with flattened horizontal cavities. These cavities were lined with a peculiar felt-like substance, which Colonel Norris, who opened the mounds, was satisfied from all the indications pertained to bodies which had been buried here, but from lapse of time had entirely crumbled to earth save these little fragments. We are therefore perhaps justified in concluding that a more thorough and careful examination of the mounds of the other group would have shown that the skeletons had so far decayed as to leave but a small part in a mound. Nevertheless it is proper to state that Colonel Norris does not coincide with this conclusion, but thinks that the dismembered skeletons were buried as found. Possibly he is correct.

In this connection, and before referring to the mounds of this district on the Illinois side of the Mississippi, I desire to call attention to some modern Indian burials in this region. As the statements here made are from one claiming to be an eye-witness, I give them as related to the Bureau assistant.

The locality is a level plat in a bend of the Des Moines River between Eldon and Iowaville, Wapello County. The plat of this area and the sites of the burial places, as shown in Fig. 9, are based upon the statements of Mr. J. H. Jordan (the person referred to), who has resided here since the close of the Black Hawk war, and was the agent of the Sacs and Foxes from their removal hither after the war until Black Hawk's death, September 15, 1838.[19]

The extreme width of the area represented is about 2 miles. Close to the point of the bend formerly stood the agency building, near which is the present residence of Mr. Jordan. The triangle marks the position of Black Hawk's grave; the parallel lines, the race-tracks; the rings in the upper corner, the mounds of the Iowas; those in the lower corner, near Iowaville, the mounds of the Pottawattamies; and the open dots, near the same point, the place where the scaffolds for their dead stood.

Mr. Jordan says:
