I am informed by the same gentleman who saw these petroglyphs in 1857 that there were at one time many more some 3 or 4 miles from this place, near Homer, Nebraska, in the vicinity of a large spring, but he also said that as it is a favorite picnic ground for the country people the carvings are probably destroyed. I presume others may be found in these bluffs. I surmise that the almost cave-like nature of the place where the carvings I have above attempted to describe are situated rendered it a favorite camping ground and resting place; and also that the ravines above mentioned made easy trails from the Missouri bottom up to the higher grounds farther from the river, because it obviated the ascent of the very steep bluffs. The Winnebago Indian reservation is a few miles south of this locality, but they were placed here by the Government as late as from 1860 to 1865. Previous to that time I think this ground was occupied by the Omahas. I have been unable to gain any information as to the Indians who carved these figures or as to their meaning. [Illustration: BUREAU OF ETHNOLOGY TENTH ANNUAL REPORT PL. XIII PETROGLYPHS IN NEBRASKA.] The most instructive of the petroglyphs, copies of which are kindly furnished by Mr. Quick, is presented as Pl. XIII, and selected sketches from that and the other petroglyphs copied are shown as Figs. 52 and 53. [Illustration: FIG. 52.--Characters from Nebraska petroglyphs.] Frank La Flèche, of the Bureau of Indian Affairs, in February, 1886, communicated the following: Ingna^nχe gikáχa-ina is the Omaha name of a rock ledge on the banks of the Missouri river, near the Santee agency, Nebraska. This ledge contains pictographs of men who passed to the happy hunting grounds, of life size, the sandstone being so soft that the engravings would be made with a piece of wood. They are represented with the special cause (arrow, gun, etc.), which sped them to hades. The souls themselves are said to make these pictographs before repairing “to the spirits.” [Illustration: FIG. 53.--Characters from Nebraska petroglyphs.] Rev. J. Owen Dorsey, of the Bureau of Ethnology, says that the probable rendering of the term when corrected is, “Spirit(s) they-made-themselves the (place where).” NEVADA. Petroglyphs have been found by members of the U. S. Geological Survey at the lower extremity of Pyramid lake, Nevada, though no accurate reproductions are available. These characters are mentioned as incised upon the surface of basalt rocks. Petroglyphs also occur in considerable numbers on the western slope of Lone Butte, in the Carson desert. All of these appear to have been produced on the faces of bowlders and rocks by pecking and scratching with some hard mineral material like quartz.
