The small, low, flattened mounds of the lower Mississippi Valley are a

problem to archeologists. They have been studied principally near the

Mississippi River, in Arkansas and Missouri, and for many years it was

thought that in the latter State they are confined entirely to the

southeastern portion. Recently they have been found much farther to

the north and the west than they were supposed to exist.

A group, rather limited as to number and to the area covered, is at

the head of a narrow valley trending northward from Granite Mountain

in Iron County.

"Near Iron Mountain, in St. François County, more than 500 of these

small mounds, arranged in parallel rows following the direction of the

watercourses, were counted within a radius of 3 miles."[1]

The next group known north of this is on the right bank of Plattin

Creek in Jefferson County, about 12 miles from the Mississippi.

"A group of some 50 similar mounds is situated on the right bank of

the Meramec, about 6 miles above its mouth, in Jefferson County."[2]

The most northern group so far observed is near Ferguson in St. Louis

County, Missouri, where 46 are located on a narrow ridge which has the

same general elevation as the table-land. The ridge extends around the

head of a ravine, and the mounds are placed along its crest or on the

gentle slopes near the top. There are 10 or 12 at the southern edge of

Ferguson, on an overflow bottom bordering a small creek.

Toward the west from the swamp region a small group is in a broad

valley near Alton in Oregon County, which borders on Arkansas. They

are scattered along a gentle slope which has a little stream at the

foot.

In Dent County four groups are known. One is on the infirmary farm

south of the town of Salem. Most of these are but slightly changed

from their natural condition. Another group is 6 miles east of Salem.

These also are largely intact. A third is on the road from Salem to

Short Bend. The fourth is at the edge of Salem, on the Rolla road.

"On the high plateau of Dallas County, north of the Niangua ... within

an area smaller than 10 square miles, 860 were counted."[3]

Three groups are well marked in Phelps County. A mile east of Rolla

they begin at the line of the Frisco Railway and extend southward in a

shallow valley or "draw." Some are on the overflow flat bordering the

little stream, but most of them are on the slopes to either side.

South of Dillon they extend for a mile in a slight depression.

Beginning at the Soldier's Home in St. James, the largest number yet

found out of the swamp region lie for 2½ miles on both sides of a

small creek running eastward north of the Frisco Railway. These reach

from low land subject to overflow to an elevation of fully 50 feet up

the hillsides.

Several groups occur in Pulaski County. Four miles southwest of Big

Piney post office, near the site of what is known as "The Ranch

House," is a little wet-weather stream along both banks of which are

probably a hundred of these structures. Farther up this stream are two

other groups, the three including a distance of about 4 miles in

length between their outer limits. West of these and south of

Bloodland is a fourth group belonging with these.

In the level bottom between Big Piney River and the branch flowing

from the Miller Spring 2 miles from Big Piney post office a number of

these mounds formerly existed; and on the opposite side of the Big

Piney, in an extensive bottom, were many of them. All these have now

disappeared under cultivation.

On the outer bend of the Devil's Elbow, on Big Piney 3 miles above its

mouth, some of these mounds stood. They are described as being from 2

to 3 feet high; the number was not stated, but there is not room for

many in the narrow strip where they were located.

In the extreme western part of Morgan County, at Stover, is a group

scattered over an area at least half a mile across in any direction.

The distance between the mounds varies from 25 to 150 feet. They are

mostly on gentle slopes, though some are on the crest of the ridges.

Many of these are well preserved, some of them having never been under

cultivation.

In Osage County there are more than a hundred at the eastern edge of

Rich Fountain. They are in low flat ground which is muddy or even

boggy in wet weather.

It will be noticed that all those from Alton westward and

north-westward are in line with the route from southeastern Missouri

to the plains of Kansas and Nebraska.

Practically, however, the northern limit of this type, in great

numbers, is in St. François County, near Farmington. From here they

extend almost continuously into Louisiana and Texas.

In nearly every part of southern Missouri east of the Iron Mountain

Railway they occur in closely connected groups, reaching sometimes for

miles except where the continuity is broken by a slough or other

unfavorable condition. They are found everywhere--on high,

well-drained levels; on sloping ground, sometimes so steep that it may

well be called a hillside; in low "crawfish land"; in swamps where, in

the driest weather, even after a prolonged drought, they can be

reached only by wading through water or muck. The last, however, may

have been more easily accessible when built, their present condition

being due to the general subsidence of this region during the

earthquake period of 1811. The existing sloughs and sluggish bayous

are the widenings and extensions of streams which at the time these

mounds were constructed were no doubt bordered by banks above ordinary

overflow and readily reached by canoes. Manifestly the country was

well populated, and therefore presumably practically timberless;

consequently the flood water would rapidly pass away and the streams

not be choked by drift and other débris as is the case at present.

Various theories, most of them advanced by persons who are but

slightly, if at all, familiar with the country, have been propounded

to account for mounds of this character. Their vast number has led

some writers to believe that they can not be artificial but must be

due to natural phenomena; as, for instance, that these, as indeed all

mounds, were piled up by floods, Noachic, glacial, or local; or that

they result from the industry and energy of burrowing animals, such as

foxes, badgers, ground hogs, rabbits, prairie dogs, gophers,

chipmunks, or even ants; the character of the assumed flood or the

species of the supposed burrower depending to some extent upon

locality, but principally upon the theorizer's insufficient knowledge

of animal industry or of the action of torrential waters. Others are

convinced they are formed by the piling up of earth around a bush,

clump of grass, stone, or other object acting as a nucleus about which

wind-borne material may accumulate--overlooking the fact that clay,

gravel, or gumbo soil can not be carried by wind, and that lighter

soil or sand will form elongated instead of circular masses. Another

supposition is that they are due to stream erosion; flood waters

washing away the soil between them and thus leaving the earth

composing the mound in its original position. The same objection

applies to this as to the wind-blown theory, namely, that we can not

imagine water acting with such mathematical regularity and intelligent

discrimination, especially upon slopes which lie at all sorts of

angles with the trend of the current.

Persons who recognize their human origin have suggested that they were

erected as stands for hunters, from which they could detect game at a

greater distance, or could take better aim as the animal passed; or

perhaps as camping places while waiting; but in many places more than

half the area of the ground over several acres is occupied by such

piles of earth, promiscuously distributed. This implies more hunters

than animals.

For a long time it was supposed that they were burial mounds, like so

many such structures found over the country; but this idea has been

dispelled by the failure to discover in them any evidences of such

purpose; no human bones nor any of the artificial objects commonly

placed with the dead have ever been found in them unless under such

conditions as to show their presence was accidental.

Two very plausible theories have found general acceptance: That they

were the sites of dwellings, placed on them to be out of the mud in

wet weather; and that they were in the nature of garden beds, thus

elevated for growing any food products which needed a comparatively

dry soil, or might be injured by temporary accumulation of water from

excessive rainfall.

But they were not "residence mounds" or "house sites" in the sense

that they furnished a base or foundation for structures which were

used as dwellings; for there has never been found on their surface or

in the earth immediately around them any of the débris invariably

accompanying Indian huts or houses, such as fireplaces, ash beds,

burned rocks, broken implements, or fragments of bones and pottery.

These considerations also interfere with a full acceptance of the

hypothesis that they are remains of houses built of wood and covered

with earth. It is true that such evidence is very frequently found in

other localities; but to establish the fact that they were residence

sites, refuse of this kind should be found wherever the mounds occur.

J.B. Thoburn arrived at this conclusion from the resemblance of some

of them in their outlines to the grass-covered houses of the Pawnees;

and it is believed that this tribe in its migration from the south

followed approximately the route along which these small elevations

are found. When the Pawnees--assuming they were the builders--passed

on westward they could not procure timbers of sufficient strength to

hold up the earth, so they used light frames and covered them with

grass.

Bushnell arrived earlier at the same conclusion. He says, concerning a

few mounds of this character in Forest Park, St. Louis: "In the case

of the seven mounds on the elevated grounds, the finding of potsherds,

pieces of chipped chert, and the indication of fire, all on what

appeared to have been the original surface, would point strongly to

their having been the remains or ruins of earth-covered lodges." He

gives citations from early explorers in support of this theory, and

adds, "But in other mounds these indications did not occur."[4]

Such an explanation finds support in the vast number of these

structures. In building, the aborigines naturally chose the sort of

timber which was soft and light, consequently easy to cut and to

handle, such as willow or cottonwood. This soon decays. But no matter

what variety of wood was utilized, not many years would be required,

under the conditions supposed, to weaken its fiber until it could no

longer uphold the weight of earth on the roof, and a new house must be

erected. Several such renewals would be needed in the course of a

century; so that the ruins of an ordinary village might create the

impression that a large settlement had existed on its site.

The explanation of "agricultural use" is probably correct in some

instances, for frequently the mounds are made of earth gathered up

around their base, and so not only would be of value in a wet season,

but would afford a much greater depth of fertile soil for sustenance

of plants. In some localities modern farmers find that on such mounds

crops are much better than on the low spaces between them. On the

other hand, a majority of the small mounds in the lower counties of

southeastern Missouri are composed either of the hard, reddish, sandy

clay which forms the subsoil of the land above overflow; or of the

tough, waxy, black "gumbo" of the swampy or flat lowlands. In either

case they are almost invariably sterile, so that in a cultivated field

the position of a mound is easily determined even from a considerable

distance by the feebler growth on its surface. Moreover, in many

places, hundreds of them occurring within an area of a few square

miles are built on clay lowlands where crawfish abound, within a few

rods of sandy, well-drained ridges whose soil is never muddy more than

a few hours after the hardest rain, and produces as fine corn and

wheat as can be raised in any part of the State.

In short, no matter what suggestion has been offered as to their

purpose or uses, objections to it can be brought and sustained. It is

not improbable that, in the end, it will be found the difficulty lies

in trying to place in a hard and fast category a variety of structures

which are similar in appearance but which were intended for various

uses. With more comprehensive study, it may be that a classification

is possible which will interpret what is now obscure. Instead of

uniformity, there was probably great diversity of motives, ideas, and

beliefs which led to the building of these as well as of other mounds;

and when the key is once obtained the explanation which will account

for one may be very different from that which as clearly accounts for

another.

A few of these mounds have been explored by the writer, but no

discoveries were made upon which can be based a definite statement as

to their probable purpose.

NEW MADRID COUNTY

On the farm of A.B. Hunter, 7 miles north of New Madrid, more than 60

of these mounds, irregularly placed, extend for half a mile along the

west bank of St. John's Bayou, the extreme width of the group being

about 200 yards. The largest mound, standing on the edge of the

terrace, was 6 feet high and 75 feet across. On the original surface,

over a small area at the central part, were decayed fragments of human

bones; so this was probably erected as a tumulus. The others were much

smaller; from a foot to 3 feet high, and 30 to 50 feet in diameter.

Six of these, varying in size from the largest to the smallest, were

thoroughly excavated within the original margin and down to the

undisturbed earth beneath them. No artificial object was found in any

of them except here and there a fragment of pottery or a small amount

of ashes or a piece of charcoal, not intentionally deposited but

gathered up and carried in with the earth in the course of

construction. There were no distinct fire-beds or ash piles at the

bottom, or in any part of the mound; nor were there any holes in which

posts may have stood.

* * *

ST. FRANÇOIS COUNTY

Nearly 2 miles south of Farmington, on Quesnel's land, are about 30

very small, low mounds, none more than 18 inches high or 25 feet

across. They are on the general level, some of them on a gentle slope,

of the first upland above the St. François River and a mile from that

stream at its nearest point.

Half a mile to the south of these is a group of similar mounds on the

farm of Isaac Hopkins, on a gently sloping hillside, and from 30 to 40

feet above the level of the overflow bottom land. One of these has

been gradually worn away by the encroachment of a gully until more

than half of it has disappeared. While the curvature of its surface is

very apparent, and the remnant of its margin sufficiently distinct to

show its regularity of outline, careful inspection of the face formed

by the erosion fails to reveal any trace of stratification, or line of

demarcation between the bottom of the mound and the original surface.

There is precisely the same uniformity of change from the grass roots

to the underlying gravelly soil that exists in the exposed bank at any

point to either side of the mound. Mr. Hopkins, desirous of knowing

what might be in the mound, or why it was built, has noted the

appearance of the earth from the time the gully reached its margin. At

no time has its appearance differed in the least from what it presents

now.

On the river bottom portion of Mr. Hopkins's farm, and on the

adjoining Goings and Townshend farms to the southward, are many mounds

lying along both sides of the Belmont division of the Iron Mountain

Railway. Fully 100 were observed within a distance of a mile; and they

are said to continue both up and down the river. They are all above

flood stage, except in time of extreme high water. They range from a

foot to 3 feet high, and from 20 to 40 feet across; but some of them

have been lowered and broadened by cultivation. They are of the same

earth as the ground around them. Mr. Hopkins says crops are much

better on the mounds than on the area between them. This is no doubt

due to the greater amount of productive soil in the one case, and to

the excess of moisture in the other; the railway embankment impeding

drainage in the lower part. Oak trees 4 feet in diameter grew on the

mounds before they were cleared off.

Two of these mounds were completely removed, down into the subsoil.

The first was 18 inches high and 35 by 40 feet across; the variation

in breadth resulting from continual cultivation in one direction. It

contained nothing whatever of artificial character, not even a scrap

of pottery. There were no post holes, no indications of a fire bed, no

trace of a distinction between the mound and the soil below it. In

fact, except for the greater thickness of the superficial dark earth

there was no difference between the appearance of the face of the

excavation and that of a hole dug at random in the field.

The second mound was somewhat larger than the first, being 2 feet high

and 40 feet across, and at a little higher level toward the edge of

the field. It was the largest which could be excavated of this group.

As in the first mound opened, there was no worked object, if a small

flint flake be excepted; no ashes; no fire bed; no trace of

demarcation between the mound and the original surface of the ground,

though in each mound the excavation over the entire area was carried

down into the gravelly, hard-packed subsoil. Its artificial origin is

clearly proven, however, by four holes dug into the earth beneath it

before its construction. Nine feet a little north of the center, which

was assumed to be the highest point of the mound, was a hole (A) 12 by

14 inches and 14 inches deep, with a flat bottom, the sides as regular

as could be expected in hard soil dug out in primitive manner. Nine

feet west of the center was a hole (B) a foot across, 10 inches deep,

with a solid though somewhat irregular bottom. Near the center was a

conical hole (C) a foot deep and the same across the top. Four feet

from it, west of north, was another (D) of about the same size and

shape. The measures given are of course only approximate, as the sides

of all the holes were somewhat uneven, but they are practically

correct. The depth was measured from the top of the gravelly subsoil.

Fourteen feet east of south from the center was an irregular hole (E)

about 2 feet deep to the bottom of the loose dirt in it. This had not

been dug, but was due to the decay of a tree which grew here before

the mound was made. At the top of the dirt filling this hole was a

piece of decayed bark, apparently oak, which had grown in the air; and

farther down fragments of root bark. Eight feet east of the center was

a hole (F), similar to the last, 10 inches deep and averaging 2 feet

across. This, also, resulted from the decay of a stump.

A plan of the holes is given in figure 37. The dotted lines are merely

to show direction and distance.

[Illustration: FIG. 37.--Plan of House Mound in St. François

County, Mo.]

This mound offers confirmation of the belief that such structures, or

some of them at least, mark the sites of dwellings. With the two

trees, E and F, the posts, A and B, would form the corners of an

irregular quadrangle; the two posts, C and D, would support the inner

ends of roof timbers. While no trace of posts or roof timbers

remained, it is difficult to imagine for what other purpose these

holes would be dug; and in this heavy, wet earth all traces of wood

must in time disappear. Conversely, the total absence of a fireplace,

potsherds or other remains, and of any sign of a floor, would serve to

dispel the assumption that this spot was ever inhabited even for a

short time. The evidence is as strong one way as it is the other.

In short, the limited observations above recorded leave the question

of origin and purpose just where it was.

* * * * *

Some years ago one of the mounds at Ferguson, St. Louis County, was

opened. No remains of any sort were discovered, according to the

report of the excavators; but on the original surface, at the center

of the mound, was a fire bed in and about which were ashes, charcoal,

and fragments of rude pottery.

No excavations have ever been made in the mounds near Granite

Mountain; but a tortuous little stream has undercut several of them,

thus making vertical sections as in the case of the mound at Hunter's,

near Farmington. In some mounds only a small portion near the margin

has been removed; in others the erosion has progressed to such an

extent that observations were possible at varying distances, to and

beyond the center. In every instance a monotonous uniformity of

appearance prevails from the top of the mound into the underlying

gravel. At no level is there a sign of a floor, fire bed, or other

evidence of human work; and no difference can be detected between the

earth upon which the mound rests and that on either side. Yet the

mounds are indubitably artificial.

Exactly the same remarks apply to several mounds on the County Farm,

near Salem. A little creek and a drainage ditch have cut away varying

portions of them, and they merge insensibly into the soil and gravel

on either side.

* * * * *

In further support of the theory that these mounds are the remains of

earth-covered houses, a few extracts relating to the area under

discussion will be given from Dr. Cyrus Thomas in the Twelfth Annual

Report of the Bureau of Ethnology:

Near "Beckwith's Fort," in Mississippi County, Missouri, are (p.

189)--

Low, flattish, circular mounds * * * [which] appear to belong to

two classes, those used for dwelling sites and those used for

burial purposes, the former being the higher and the color of the

surface layer darker than that of the other class. This darker

color of the surface layer is probably due to the fact that

immediately below it are found fire-beds with burnt earth,

charcoal, ashes, and the bones of animals, (mostly split). There

are seldom any human skeletons or entire vessels of pottery in

the mounds of this class though the earth is filled with

fragments of broken vessels.

In describing mound excavations in Crittenden County, Arkansas, the

explorer states (p. 227):

As an almost universal rule, after removing a foot or two of top

soil, a layer of burnt clay in a broken or fragmentary condition

would be found, sometimes with impressions of grass or twigs,

which easily crumbled but was often hard and stamped apparently

with an implement made of split reeds of comparatively large

size. This layer was in places a foot thick and frequently burned

to a brick red or even to clinkers.

Below this, at a depth of 3 to 5 feet from the surface, were more

or less ashes, and often 6 inches of charred grass, immediately

covering skeletons. The latter were found lying in all

directions, some with the face up, others with it down, and

others on the side. With these were vessels of clay, in some

cases one, sometimes more.

The positions of the skeletons in this mound would indicate that while

the inmates of the house were asleep the roof fell and killed them. It

was customary among some southern Indians to bury the dead under the

floors of the houses; but the text clearly shows that these skeletons

were lying on the floor. It would be supposed from most reports, not

only in the volume quoted, but from various other sources as well,

that only the walls of these houses were plastered with mud, the roof

being of thatch alone. It seems to be overlooked that the tops of the

houses would have even more need of such protection than the sides.

The marks indicating that the clay was "stamped apparently with an

implement made of split reeds" are only the impressions of the reeds

or saplings by which the clay was supported; the "brick like" or

"clinker like" condition of the clay being due, of course, to the

destruction of the house by fire.

Adair, in his History of the Southern Indians, says they daub their

houses with tough mortar mixed with dry grass; that they build winter

or hot houses after the manner of Dutch ovens, covered with clay.

Again:

They are lathed with cane and plastered with mud from bottom to

top, within and without, with a good covering of straw.

This seems to mean that the entire building was plastered with mud,

and then covered with grass to shed the rainfall.
