The ancient inscription on a bowlder of greenstone rock lying in the margin of the Assonet, or Taunton River, in the area of ancient Vinland, was noticed by the New England colonists so early as 1680, when Dr. Danforth made a drawing of it. This outline, together with several subsequent copies of it, at different eras, reaching to 1830, all differing considerably in their details, but preserving a certain general resemblance, is presented in the Antiquatés Americanes [_sic_] (Tab. XI, XII) and referred to the same era of Scandinavian discovery. The imperfections of the drawings (including that executed under the auspices of the Rhode Island Historical Society, in 1830, Tab. XII) and the recognition of some characters bearing more or less resemblance to antique Roman letters and figures, may be considered to have misled Mr. Magnusen in his interpretation of it. From whatever cause, nothing could, it would seem, have been wider from the purport and true interpretation of it. It is of purely Indian origin, and is executed in the peculiar symbolic character of the Kekeewin. ROCK CARVINGS IN PENNSYLVANIA. Many of the rocks along the river courses in Northern and Western Pennsylvania bear traces of carvings, though, on account of the character of the geological formations, some of these records are almost, if not entirely, obliterated. Mr. P. W. Shafer published in a historical map of Pennsylvania, in 1875, several groups of pictographs. (They had before appeared in a rude and crowded form in the Transactions of the Anthropological Institute of New York, N. Y., 1871-’72, p. 66, Figs. 25, 26, where the localities are mentioned as “Big” and “Little” Indian Rocks, respectively.) One of these is situated on the Susquehanna River, below the dam at Safe Harbor, and clearly shows its Algonkin origin. The characters are nearly all either animals or various forms of the human body. Birds, bird-tracks, and serpents also occur. A part of this pictograph is presented below, Figure 149, page 226. On the same chart a group of pictures is also given, copied from the originals on the Allegheny River, in Venango County, 5 miles south of Franklin. There are but six characters furnished in this instance, three of which are variations of the human form, while the others are undetermined.
