The second cut shows a group of sacred enclosures at Hopeton, Ohio, located on the third terrace. The walls of the rectangle are of a clayey loam, fifty feet thick and twelve feet high, without a ditch. The summit is wide enough for a wagon road. The walls of the circle are somewhat lower and composed of clay differing in color from that found in the vicinity. The two smaller circles have interior ditches. The cut gives a view of the same works as they appear from the east. The parallel embankments in the south are one hundred and fifty feet apart and extend half a mile to the bank of an old river bed. Two hundred paces north of the large circle, and not shown in the cuts, is another circle two hundred and fifty feet in diameter.
Cedar Bank Enclosures.
The enclosure shown in the next cut is that at Cedar Bank, near Chillicothe, Ohio, and seems to partake somewhat of the nature of a fortification. The west side is naturally protected by the river bank, and the other sides are enclosed by a wall and ditch, each forty feet wide and five to six feet high or deep. The bed of a small stream forms a natural ditch for one half of the eastern side. Within the enclosure in a line with the entrances is a raised platform four feet high, measuring one hundred and fifty by two hundred and fifty feet, with graded ways thirty feet wide, leading to the summit. The parallels outside the enclosure are three or four feet high. The earth-work in Randolph County, Indiana, is sufficiently explained by the cut. This work, like the preceding, would seem to have been constructed partially with a view to defence. The work shown in the next cut is part of a group in Pike County, Ohio. The circle is three hundred feet in diameter.
