PLATE XXVIII. PORTSMOUTH WORKS—GROUP C.

This group is on the Kentucky shore, and principally occupies the third terrace, or high level at the base of the hills bordering the valley. The ground is here considerably broken. The northern portion of the work is somewhat lower than the remainder, and a small brook cuts through the outer wall on the south. This work is in many respects novel, and for this reason, as well as from the connection in which it is found, is entitled to an attention not otherwise merited; for no person looking merely for what is striking from position, or imposing from magnitude, would be apt to pay it a second visit. It consists of four concentric circles, placed at irregular intervals in respect to each other, and cut at right angles by four broad avenues, which conform in bearing very nearly to the cardinal points. A large mound is placed in the centre; it is truncated and terraced, and has a graded way leading to its summit. A reference to the plan and sections will exhibit in one view the dimensions and general aspect of the work, obviating the necessity of a detailed description.

The mound in the centre, at first glance, would be taken for a natural elevation; and it is possible that it is a detached spur of a hill, modified and perhaps enlarged by art. A hillock in such a position is, however, a circumstance of very rare occurrence. From the level summit of this mound, a complete view of every part of the surrounding work is commanded. Were it not for the obstructing forests, it is believed the eye might obtain, from this position, a view of the river and intermediate plain, as also of the works beyond, and several miles distant. On the supposition that this work was in some way connected with the religious rites and ceremonies of the builders, this mound must have afforded a most conspicuous place for their observance and celebration. And it is easy, while standing on its p082 summit, to people it with the strange priesthood of ancient superstition, and fill its avenues and line its walls with the thronging devotees of a mysterious worship. Whatever may have been the divinity of their belief, order, symmetry, and design were among his attributes; if, as appears most likely, the works that most strongly exhibit these features were dedicated to religious purposes, and were symbolical in their design.

About one mile to the west of this work are a number of mounds, some of considerable size, and also a small circular work, D, of exquisite symmetry and proportion. It consists of an embankment of earth five feet high by thirty feet base, with an interior ditch twenty-five feet across by six feet deep, enclosing an area ninety feet in diameter, in the centre of which rises a mound eight feet high by forty feet base. A narrow gateway through the parapet, and a causeway over the ditch, lead to the enclosed mound.

The above view, taken on the spot, will illustrate the appearance of this class of works. Nothing can exceed their regularity and beauty, when clothed with turf or covered with forest trees.

PLATE XXIX. No. 1. ANCIENT WORKS, MONTGOMERY COUNTY, OHIO.[62]

These works are situated on the east bank of the Great Miami river, six miles below Dayton, Montgomery county, Ohio. They are built upon the second bottom or terrace, which is here nearly a mile broad, and elevated about twenty feet above the river. The plan of the group coincides very nearly with that of some of the p083 more regular works of the Scioto valley. (See Plates [XX] and [XXI].) It seems never to have been completed; at any rate, the various parts were never connected. A portion of the great circle A has been washed away by the river, which here encroaches upon the second terrace. The diameter of this circle is one hundred feet greater than that of the corresponding large circle of the Scioto works; and the same proportionate increase in size is to be observed in the square and lower circle. The embankments are now between five and six feet high, and have a base fifty feet wide. They are composed of a tough, yellow clay, which is found to be superimposed on the loam of the original level. It must have been brought from a distance, as there are no excavations perceptible in the vicinity. The embankments, as in the case of several other works which have been noticed, appear to have been some time or other subjected to the action of fire. They are unaccompanied by a ditch.

[♠]

The Miami canal extends through these works, and the little town of Alexandersville is laid out over a portion of the smaller circle. The clay composing the embankments is now much used in the manufacture of bricks, and but a little time will elapse before the work will be entirely obliterated.

We can only regard this structure as kindred in its purposes to those above alluded to in the Scioto valley, and associate it with the superstitions of the builders. It tends to confirm the impression produced by the other works, that some significance attaches to the combination of the two circles and the square.

PLATE XXIX. No. 2. ANCIENT WORKS, SCIOTO COUNTY, OHIO.[63]

This singular work is situated five miles north of Portsmouth, Scioto county, Ohio, on the west bank of the Scioto river. It is not a true ellipse, but approaches very near it. Its longest axis is four hundred and eighty feet, its conjugate diameter four hundred and seven feet. It is built upon a high and beautiful level, elevated some sixty or seventy feet above the Scioto river, which flows about half a mile to the eastward. The embankment is unaccompanied by a ditch, and is about three feet in height, by thirty feet base. It has, as shown in the plan, a single gateway, ninety feet wide, opening to the south-east, which is covered by a long exterior mound, of about the same height with the embankment of the enclosure.

Within this enclosure is a large irregular mound, which, from its resemblance to the animal-shaped mounds of Wisconsin, of which notice will be taken in p084 another place, constitutes by far the most interesting feature of the work. It is of the form and relative size indicated in the plan, and is composed of loose broken sandstone and earth, based upon dislocated and broken sand-rock. It is from one to eight feet high, being lowest at the eastern end or head, and at the projecting points. It is probably of the same design with those of Wisconsin, already alluded to, which occur in great numbers and in long and apparently dependent ranges. None of those, however, so far as known, are found enclosed after the manner of the one here presented. (See “Remains of the North-West.”) No explanation of the probable design of this work will be attempted here: it is impossible, however, to disconnect it from the superstitions of the ancient people. An interesting fact is communicated by F. Cleveland, Esq., of Portsmouth, who assisted Mr. Whittlesey in making the survey of this work, and who was engineer on the Ohio canal when it was in progress; viz. that the workmen engaged in excavating found large quantities of mica, in sheets, in the immediate vicinity of this enclosure. This mineral is found in great abundance in the mounds, and in the neighborhood of these ancient works.

PLATE XXIX. No. 3. ANCIENT WORKS, FRANKLIN COUNTY, OHIO.[64]

This work occurs on the banks of Olentangy creek, a tributary of the Scioto river, about one mile west of the town of Worthington, Franklin county, Ohio. The plateau upon the edge of which it is situated is elevated about fifty feet above the bottoms of the Olentangy, and consists of a clayey soil resting on the black shale formation of Ohio. The work is rectangular in form; its sides correspond very nearly with the cardinal points, (varying but five degrees,) and measure six hundred and thirty, and five hundred and fifty feet respectively. The walls are unaccompanied by a ditch, and are very slight, though distinctly traceable. In the line of the southern wall is a large truncated mound, C, twenty feet in height, and measuring one hundred and ninety-two feet in diameter at the base, and seventy-six feet in diameter at the summit. It is covered with large trees. The wall that leads from this mound to the left, is placed a little further outwards than that leading to the right. The mound D, in the centre of the enclosure, is small and low. Near the south-western corner of the work is a small circle, with an interior ditch and single entrance; it is one hundred and twenty feet in diameter. Some distance to the north-west of the enclosure, and on the opposite side of a deep ravine, is another small circle, one hundred and forty feet in diameter, with three entrances. p085

PLATE XXX. No. 1.[65]

This work is situated four miles south-west of the town of Hamilton, Butler county, Ohio, on S. 10, T. 1, R. 2, between the Great and Little Miami rivers. It is indicated by the letter C, in the Map of a section of the Miami valley (Plate [III], No. 2).

The ground upon which this unique work is built is the level bottom of the Miami river, at a distance from any high lands. The principal or square portion of the work is constructed of an embankment of earth, about four feet high by fifty feet base, unaccompanied by a ditch. The walls of the circular or irregular portion of the work, towards Pleasant run, are considerably heavier, and have an interior ditch. The work is not an exact square, nor are its gateways disposed with the usual degree of regularity. The walls, at the western angle, terminate in a large oblong mound, and a small mound occupies the centre of one of the attached circular works.

At a short distance from the enclosure, towards the south, are two large mounds, placed one hundred and thirty-five feet apart. They are each about two hundred and fifty feet in circumference, and fifteen feet in perpendicular height, and are in part composed of large stones. These mounds, as also the larger portion of the enclosure, are situated in timbered land, the forests presenting the usual primitive aspect. The trees growing upon the walls are of the largest size, and are surrounded by the fallen and decayed trunks of their predecessors. From this work to the Miami river, the distance is now about half a mile; the intervening bottom is low and of comparatively recent formation. It is probable that the river once washed the work, at the point now bounded by Pleasant run.

For reasons which it is here unnecessary to recapitulate, this work is deemed of religious origin.

PLATE XXX. No. 2.[66]

This work is indicated by the letter F, in the map of a section of the Miami valley, and is situated on the right bank of the Miami river, seven miles below the town of Hamilton, Butler county, Ohio, on S. 27 and 34, T. 3, R. 2, E. M.

Little can be said respecting it, except that it is a circle of considerable size, p086 bounded by an embankment, at present about two feet high, composed of earth taken up evenly from the surface, or brought from a distance. It has an entrance to the left, two hundred and seventy-five feet wide; the embankment upon either hand terminating in a small mound, between four and five feet high. The area of the enclosure is level, and covered with forest: the trees are, however, small, owing probably to the nature of the soil, which is thin and gravelly. The plain is here fifty feet above the adjacent bottoms.

About a mile north-east of this work, on the opposite bank of Indian creek, are three large mounds, on a line with each other. On the lower bottom or terrace, opposite to each mound, is a corresponding hole or excavation, from which the earth composing them was doubtless obtained.
