It is scarcely necessary to describe the works further, except to state that three lines of parallel embankments lead away from the octagon. Those extending south have been traced for upwards of two miles, and are gradually lost in the plain. It was the opinion of Mr. Atwater, one of the earliest investigators, that these lines connected with other works thirty miles away, in the vicinity of Lancaster.68 Small circles are numerous in connection with these works. It has been suggested by several that they mark the sites of circular dwellings. The larger ones, indicated by the letter “G,” are more pretentious. They have the ditch and embankment, which we have already described. Many interesting coincidents in dimensions will be perceived between portions of this work and those described in the Scioto valley.69 Although we have devoted considerable space to this branch of the Mound Builders’ work, we must still find space to describe the works at Marietta, which possessed some singular features. This cut gives us a correct plan of the works as they were when in 1788 the first settlers arrived at the mouth of the Muskingum to lay out their town. The growth of the beautiful town of Marietta has completely destroyed these works, except the elevated squares, A and B, the large mound and inclosing circle at X, with a portion of the adjoining embankments, and a small fragment of the parallel walls forming what has been called the “Graded Way.” The elevated squares are the finest examples of “temple” mounds remaining in the Ohio Valley. The circle and ditch with the conical mound inclosed is also a fine example of that class of works. From the summit of the mound an extensive view is to be had both up and down the Ohio.
