Mr. G. K. Gilbert, of the U. S. Geological Survey, has furnished a small collection of drawings of Shoshonean petroglyphs from Oneida, Idaho, shown in Fig. 39. Some of them appear to be totemic characters, and possibly were made to record the names of visitors to the locality. [Illustration: FIG. 39.--Petroglyphs in Idaho (Shoshonean).] Mr. Willard D. Johnson, of the U. S. Geological Survey, reports pictographic remains observed by him near Oneida, Idaho, in 1879. The figures represent human beings and were on a rock of basalt. A copy of another petroglyph found in Idaho appears in Fig. 1092, infra. ILLINOIS. Petroglyphs are reported by Mr. John Criley as occurring near Ava, Jackson county, Illinois. The outlines of the characters observed by him were drawn from memory and submitted to Mr. Charles S. Mason, of Toledo, Ohio, through whom they were furnished to the Bureau of Ethnology. Little reliance can be placed upon the accuracy of such drawing, but from the general appearance of the sketches the originals of which they are copies were probably made by one of the middle Algonquian tribes of Indians. The “Piasa” rock, as it is generally designated, was referred to by the missionary explorer Marquette in 1675. Its situation was immediately above the city of Alton, Illinois. Marquette’s remarks are translated by Dr. Francis Parkman (_a_) as follows: On the flat face of a high rock were painted, in red, black, and green, a pair of monsters, each “as large as a calf, with horns like a deer, red eyes, a beard like a tiger, and a frightful expression of countenance. The face is something like that of a man, the body covered with scales; and the tail so long that it passes entirely round the body, over the head, and between the legs, ending like that of a fish.” Another version, by Davidson and Struvé (_a_), of the discovery of the petroglyph is as follows: Again they (Joliet and Marquette) were floating on the broad bosom of the unknown stream. Passing the mouth of the Illinois, they soon fell into the shadow of a tall promontory, and with great astonishment beheld the representation of two monsters painted on its lofty limestone front. According to Marquette, each of these frightful figures had the face of a man, the horns of a deer, the beard of a tiger, and the tail of a fish so long that it passed around the body, over the head, and between the legs. It was an object of Indian worship and greatly impressed the mind of the pious missionary with the necessity of substituting for this monstrous idolatry the worship of the true God. A footnote connected with the foregoing quotation gives the following description of the same rock:
