In the collection contributed by Mr. Gilbert there are at least fifteen series or groups of figures, most of which consist of the human form (from the simplest to the most complex style of drawing), animals, either singly or in long files--as if driven--bird tracks, human feet and hands, etc. There are also circles, parallel lines, and waving or undulating lines, spots, and other characters. Mr. Gilbert also reports the discovery, in 1883, of a great number of pictographs, chiefly in color, though some are only incised, in a canyon of the Book cliff containing Thompson’s spring, about 4 miles north of Thompson’s station, on the Denver and Colorado Railroad, Utah. He has also furnished a collection of drawings of pictographs at Black rock spring, on Beaver creek, north of Milford, Utah. A number of fallen blocks of basalt at a low escarpment are filled with etchings upon the vertical faces. The characters generally are of an “unintelligible” nature, though the human figure is drawn in complex forms. Footprints and circles abound. Mr. I. C. Russell, of the U. S. Geological Survey, furnished rude drawings of pictographs at Black rock spring, Utah (see Fig. 1093). Mr. Gilbert Thompson also discovered pictographs at Fool creek canyon, Utah (see Fig. 1094). Mr. Vernon Bailey, in a letter dated January 18, 1889, reports that in the vicinity of St. George “all along the sandstone cliffs are strange figures like hieroglyphics and pictures of animals cut in the rocks, but now often worn dim.” Mr. George Pope, of Provo city, Utah county, in a letter, kindly gives an account of an inscription on a rock in a canyon at the mouth of Provo river, about 7 miles from the city named. There is no paint seen, the inscription being cut. A human hand is conspicuous, being cut (probably pecked) to a depth of at least one-third of an inch, and so with representations of animals. Dr. Rau (_c_) gives the design of a portion of a group carved on a cliff in the San Pete valley at the city of Manti, Utah, now reproduced as Fig. 81. He says: [Illustration: FIG. 81.--Petroglyphs near Manti, Utah.]
