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. [Illustration: FIG. 76.--Petroglyphs near Layton, Pennsylvania.] 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. [Illustration: FIG. 77.--Glyphs in Fayette county, Pennsylvania.] The designs are made in delicate lines, as if scratched with a sharply pointed piece of quartz, or possibly metal. The character _d_ on Fig. 78 is the representation of a fish, which has been accentuated by additional cutting since found. The characters resemble the Algonquian type, many of them being frequently found among those tribes living along the Great Lakes.

(_c_), is the following account: _Portsmouth rocks._--The rocks, for there are several of them, are situated on the western side of the island of Rhode Island, in the town of Portsmouth, on the shore, about 7 miles from Newport, taking the western road, and 4 miles from Bristol ferry. * * * They are partially, if not entirely, covered by water at high tide; and such was the state of the tide and the lateness of the hour when the location was ascertained, that I was unable to make a thorough examination of them. I saw sufficient, however, to satisfy me that they were formerly well covered with characters, although a large portion of them have become obliterated by the action of air and moisture, and probably still more by the attrition of masses of stone against them in violent storms and gales, and by the ruthless ravages of that most destructive power of all, the hand of man.
