In Dane county there is a remarkable group, consisting of six quadrupeds, six parallelograms, one circular tumulus, one human figure, and a small circle. The quadrupeds are from one hundred to one hundred and twenty feet long, and the figure of the man measured one hundred and twenty-five feet in length and nearly one hundred and forty feet from the end of one arm to the other. Near the village of Pewaukee, when first discovered there were two lizards and seven tortoises. One of the latter measured four hundred and seventy feet. In Adams county, Ohio, is the figure of a vast serpent; its head occupies the summit of a hill and in its distended jaws is a part of an oval-shaped mass of earth one hundred and sixty feet long, eighty wide, and four feet high. The body of the serpent extends round the hill for about eight hundred feet, forming graceful coils and undulations. Near Granville, Licking county, Ohio, on the summit of a hill two hundred feet high, is the representation of an alligator. Its extreme length is two hundred and fifty feet, average height four feet; the head, shoulders, and rump are elevated in parts to a height of six feet; the paws are forty feet long, the ends being broader than the links, as if the spread of the toes were originally indicated. Upon the inner side of the effigy is a raised space covered with stones which have been exposed to the action of fire; and from this leading to the top is a graded way ten feet in breadth. On examination it was discovered that the outline of the figure was composed of stones of considerable size, upon which the superstructure had been modelled in fine clay.
