[Illustration: FIG. 83.--Petroglyphs on Colorado river, Utah.] The characters in Fig. 84 from rocks near the preceding group are painted red, with the imprint of a hand (on the larger figure) in white. [Illustration: FIG. 84.--Petroglyphs on Colorado river, Utah.] The petroglyphs reproduced in Fig. 85 are copied from the vertical walls near the two groups immediately before mentioned. [Illustration: FIG. 85.--Petroglyphs on Colorado river, Utah.] The characters presented in Fig. 86 are copied from a vertical surface 10 by 16 feet in area and halfway up the ascent to the geodetic point west of “Windsor castle,” Pipe Spring. The human forms are similar in general design to the greater number of such representations made by the Shinumo Indians. [Illustration: FIG. 86.--Petroglyphs at Pipe Spring, Utah.] The human forms represented in Fig. 87 are from the vicinity of Colorado river, 5 miles below the mouth of the Dirty Devil river. Mr. Dellenbaugh notes that the darkest portions of the figures indicate a chiseled surface. [Illustration: FIG. 87.--Petroglyphs on Colorado river, Utah.] Fig. 88 represents a number of petroglyphs obtained at the same locality as the one last mentioned. The greater number of the characters appear to represent snakes. [Illustration: FIG. 88.--Petroglyphs on Colorado river, Utah.] Fig. 89 shows characters from the Shinumo canyon, which, according to the draftsman’s general notes, are painted. [Illustration: FIG. 89.--Petroglyphs in Shinumo canyon, Utah.] VIRGINIA. In 1886 Dr. Hoffman visited a local field 9 miles southwest of Tazewell, Tazewell county, Virginia, which can be designated as follows: The range of hills bounding the western side of the valley presents at various points low cliffs and exposures of Silurian sandstone. About 4 miles below the village, known as Knob post-office, there is a narrow ravine leading up toward a depression in the range, forming a pass to the valley beyond, near the summit of which is a large irregular exposure of rock facing west-southwest, upon the eastern extremity of which are a number of pictographs, many of which are still in good preservation. Fig. 90 is a representation. The westernmost object, i. e., the one on the extreme left, appears to be a circle about 16 inches in diameter, from the outer side of which are short radiating lines giving the whole the appearance of a sun. Beneath and to the right of this is the outline of an animal resembling a doe. [Illustration: FIG. 90.--Petroglyphs in Tazewell county, Virginia.] Other figures, chiefly human, follow in close succession to the eastern edge of the vertical face of the rock, nearly all of which present the arms in various attitudes, i. e., extended or raised as in extreme surprise or adoration. Concentric rings appear at one point, while a thunder-bird is shown not far away. About 12 feet east of this place are several figures resembling the thunder-bird.
