Mr. P. W. Norris, of the Bureau of Ethnology, found numerous caves on the banks of the Mississippi river, in northeastern Iowa, 4 miles south of New Albion, containing incised petroglyphs. Fifteen miles south of this locality paintings occur on the cliffs. He also discovered painted characters upon the cliffs on the Mississippi river, 19 miles below New Albion. KANSAS. Mr. Edward Miller reports in Proceedings of the American Philosophical Society, vol. X, 1869, p. 383, the discovery of a petroglyph near the line of the Union Pacific railroad, 15 miles southeast of Fort Harker, formerly known as Fort Ellsworth, Kansas. The petroglyph is upon a formation belonging to No. 1, Lower Cretaceous group, according to the classification of Meek and Hayden. The parts of the two plates VII and VIII of the work cited, which bear the inscriptions, are now presented as Fig. 44, being from two views of the same rock.

Middleton, formerly of the Bureau of Ethnology, in a letter dated August 14, 1886, reports that at a point in Union county, Kentucky, nearly opposite Shawneetown, Illinois, petroglyphs are found, and from the description given by him they appear to resemble those in Jackson county, Illinois, mentioned above. Mr. W. E. Barton, of Wellington, Ohio, in a communication dated October 4, 1890, writes as follows: At Clover Bottom, Kentucky, on a spur of the Big Hill, in Jackson county, about 13 miles from Berea, is a large rock which old settlers say was covered with soil and vegetation within their memory. Upon it are representations of human tracks, with what appear to be those of a bear, a horse, and a dog. These are all in the same direction, as though a man leading a horse, followed the dog upon the bear’s track. Crossing these is a series of tracks of another and larger sort which I can not attempt to identify. The stone is a sandstone in the subcarboniferous. As I remember, the strata are nearly horizontal, but erosion has made the surface a slope of about 20°. The tracks ascending the slope cross the strata. I have not seen them for some years. The crossing of the strata shows that the tracks are the work of human hands, if indeed it were not preposterous to think of anything else in rocks of that period. Still the tracks are so well made that one is tempted to ask if they can be real. They alternate right and left, though the erosion and travel have worn out some of the left tracks. A wagon road passes over the rock and was the cause of the present exposure of the stone. It can be readily found a fourth of a mile or less from the Pine Grove schoolhouse. MAINE. A number of inscribed rocks have been found in Maine and information of others has been obtained. The most interesting of them and the largest group series yet discovered in New England is shown in Pl. XII.
