Sheafer furnishes in his Historical Map of Pennsylvania, Philadelphia, 1875, a sketch of a pictograph on the Susquehanna River, Pennsylvania, below the dam at Safe Harbor, part of which is reproduced in Figure 149. This appears to be purely Algonkian, and has more resemblance to Ojibwa characters than any other petroglyph yet noted from the Eastern United States. [Illustration: FIG. 149.--Algonkian petroglyph.

Jones, United States Army, in 1873, and published in his report on Northwestern Wyoming, including the Yellowstone National Park, Washington, 1875, p. 267, _et seq._, Fig. 50, reproduced in this paper by Figure 150, in which the greater number of the characters are shown about one-fifth of their size.
