Mr. J. Sutton Wall, of Monongahela city, describes in correspondence a rock bearing pictographs opposite the town of Millsboro, in Fayette county, Pennsylvania. This rock is about 390 feet above the level of the Monongahela river, and belongs to the Waynesburg stratum of sandstone. It is detached and rests somewhat below its true horizon. It is about 6 feet in thickness, and has vertical sides; only two figures are carved on the sides, the principal inscriptions being on the top, and all are now considerably worn. Mr. Wall mentions the outlines of animals and some other figures formed by grooves or channels cut from an inch to a mere trace in depth. No indications of tool marks were discovered. The footprints are carved depressions. The character marked z, near the lower left-hand corner, is a circular cavity 7 inches deep. A copy of the inscription made in 1882 by Mr. Wall and Mr. William Arison is reproduced as Fig. 75.

Again the resemblance between these drawings, those on Dighton rock, and some of those in Ohio, introduced above, is to be noted, and the fact that all these localities are within the area formerly occupied by tribes of the Algonquian stock.
Mr. Wall also contributes a group of glyphs on what is known as the “Geneva Picture rock,” in the Monongahela valley, near Geneva. These are footprints and other characters similar to those from Hamilton farm, West Virginia, which are shown in Fig. 1088.
Mr. L. W. Brown, of Redstone, Fayette county, Pennsylvania, mentions a rock near Layton, in that county, which measures about 15 by 25 feet in area, upon the surface of which occur a number of petroglyphs consisting of the human figure, animals, and footprints, some of which are difficult to trace. From a rough sketch reproduced as Fig. 76, made by Mr. Brown, these appear to be Algonquian in type.

Mr. Brown also submitted for examination two pieces of chocolate-colored, smooth, fine grained slate, of hard texture, bearing upon the several sides outlines of incised figures. The specimens were found in Indian graves in Fayette county, Pennsylvania. The outline of the incisions, although they are not strictly petroglyphs, are reproduced in Figs. 77 and 78.
