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.
PLATE XXX. No. 3. ANCIENT WORK NEAR BOURNEVILLE, ROSS COUNTY, OHIO.
The small work here figured is one of the most beautiful in the State of Ohio. It is situated upon the highest terrace, directly facing, and about one mile distant from, the great stone hill-work of the Paint creek valley (Plate [IV]). It consists of a wall of earth, eight or ten feet in height, with a broad and shallow exterior ditch. In figure it is elliptical, with a transverse diameter of seven hundred and fifty, and a conjugate diameter of six hundred and seventy-five feet. It has a gateway one hundred and twenty feet wide, leading into it from the south-west. It opens upon a small spur of the terrace, which has been artificially rounded and graded, so as to make a regular and easy descent to the lower level. Upon either side of this grade, the banks of the terrace are steep and irregular. A very copious spring of water starts from the bank near the wall, a little to the right of the entrance. A small circle and a couple of mounds are situated on the next lower terrace, at the points indicated in the plan.
This work is admirably preserved, and is remarkable as being the only circular work at present known, which has its ditch exterior to the walls. The proprietor esteems the soil much richer within the enclosure, than upon the adjacent plain. We are unprepared to ascribe any other than a religious origin to this structure. p087
