A number at Reveillé, in the same county, are also marked. On the road to Tybo every large rock is marked, one of the figures being a semicircle with a short vertical spoke within the curve. At Reno a heavy black rock a couple of feet across is beautifully engraved to represent a bull’s eye of 4 rings, an arrow with a very large feather, and one which may mean a man. In a steep canyon 15 miles northeast of Reno, in Spanish Spring mountains, several cliffs are well marked, and an exposed ledge, where the Carson river has cut off the point of a hill below Big Bend, is covered with rings and snakes by the hundred. Several triangles, a well-formed square and compass, a woman with outstretched arms holding an olive branch, etc., are there. Humboldt county has its share, the best being on a bluff below the old Sheba mine. Ten miles south of Pioche are about 50 figures cut into the rock, many of them designed to represent mountain sheep. Eighty miles farther south, near Kane’s Spring, the most numerous and perfect specimens of this prehistoric art are found. Men on horseback engaged in the pursuit of animals are among the most numerous, best preserved, and carefully executed. The region I have gone over is of immense size, and must impress everyone with the importance of a set of symbols which extends in broken lines from Arizona far into Oregon. Fig. 55 exhibits engravings at Reveillé, Nevada. Great numbers of incised characters of various kinds are also reported from the walls of rocks flanking Walker river, near Walker lake, Nevada. Waving lines, rings, and what appear to be vegetable forms are of frequent occurrence. The human form and footprints are also depicted. [Illustration: FIG. 55.--Petroglyphs at Reveillé, Nevada.] Fig. 56 is a copy of a drawing made by Lieut. A. G. Tassin, Twelfth U. S. Infantry, in 1877, of an ancient rock-carving at the base and in the recesses of Dead mountain and the abode of dead bad Indians according to the Mohave mythology. This drawing and its description is from a manuscript report on the Mohave Indians, in the library of the Bureau of Ethnology, prepared by Lieut. Tassin. [Illustration: FIG. 56.--Petroglyphs at Dead mountain, Nevada.] He explains some of the characters as follows: (_a_) Evidently the two different species of mesquite bean. (_b_) Would seem to refer to the bite of the cidatus, and to the use of a certain herb for its cure. (_c_) Presumably the olla or water cooler of the Mohaves. The whole of this series of petroglyphs is regarded as being Shinumo or Moki. They show a general resemblance to drawings in Arizona, known to have been made by the Moki Indians. The locality is within the territory of the Shoshonean linguistic division, and the drawings are in all probability the work of one or more of the numerous tribes comprised within that division.
