Much more detailed information is given by Thomas Worsnop, viz: At Chasm island, which lies 1-1/2 miles from “Groote Eylandt,” in the steep sides of the chasms, were deep holes or caverns undermining the cliffs, upon the walls of which are found rude drawings, made with charcoal and something like red paint, upon the white ground of the rock. These drawings represented porpoises, turtle, kangaroos, and a human hand, and Mr. Westall found the representations of a kangaroo with a file of thirty-two persons following after it. In the MacDonnell ranges, 6 miles from Alice springs, in a large cave, there were paintings made by the aborigines, well defined parallel lines, intersected with footprints of the emu, kangaroo rat, and birds, with the outlines of iguana, hands of men, well sketched and almost perfect. The parallel lines were of deep red and yellow colors, with brown and white borders; the footprints of light red, light yellow, and black; the outlines of the animals and hands were of red, yellow, white, black, wonderfully (considering it was done by savages) displayed and blended. All the paintings were in good preservation and evidently touched up occasionally, as they looked quite fresh. I can only conjecture that these paintings were left as a record, a life-long charm, against the total destruction of the above animals. The paintings were seen by Mr. S. Gason, of Beltana, in the year 1873. Very interesting groups of native drawings are to be seen in the caves of the Emily gorge in the MacDonnell ranges. Many of these drawings represent life-size objects. The same author, page 20, describes the petroglyph copied in Fig. 130 as follows: [Illustration: FIG. 130.--Petroglyph on Finke river, Australia.] Mr. Arthur John Giles in the year 1873 discovered, at the junction of Sullivan’s creek with the Finke river, carvings on rocks. The sketch represents a smooth-faced rock, portion of a rock cliff about 45 feet high, composed of hard metamorphic slate. The lower portion of the sculptured face has been worn and broken away, forming a sort of cave. From the level of the creek to the lower edge of the sculptured rock is about 15 feet. The perpendicular lines are cut out, forming semicircular grooves about 1-1/2 inches in diameter, cut in to a depth of nearly half an inch; all remaining figures are also carved into the solid rock to a depth of one-fourth of an inch. The same author, page 14, gives the following description of some pictures discovered between 1831 and 1840 by Capt. Stokes on Depuch island, one of the Forestier group in Dampier archipelago, on the western coast of Australia:
