Mr. Gatschet remarks that the Tuálati tell a trivial story to explain the origin of these pictures, the substance of which is as follows: The Tillamuk warriors living on the Pacific coast were often at variance with the several Kalapuya tribes. One day, passing through Patten’s valley to invade the country of the Tuálati, they inquired of a woman how far they were from their camp. The woman, desirous not to betray her own countrymen, said they were yet at a distance of one (or two?) days’ travel. This made them reflect over the intended invasion, and, holding a council, they decided to withdraw. In commemoration of this the inscription, with its numeration marks, was incised by the Tuálati. Dr. Charles Rau received from Dr. James S. Denison, physician at the Klamath agency, Lake county, Oregon, a communication relative to the practice of painting figures on rocks in the territory of the Klamath Indians in Oregon. There are in that neighborhood many rocks bearing painted figures; but Dr. Rau’s (_b_) description refers specially to a single rock, called Ktá-i Tupákshi (standing rock), situated about 50 yards north of Sprague river and 150 yards from the junction of Sprague and Williamson rivers. It is about 10 feet high, 14 feet long, and 12 or 14 feet deep. Fig. 69, drawn one-twelfth of the natural size, illustrates the character of the paintings seen on the smooth southern surface of this rock. The most frequent designs are single or concentric circles, like Fig. 69, _a_, which consists of a dark red circle surrounded by a white one, the center being formed by a round red spot. Fig. 69, _b_, painted in dark red and white colors, exhibits a somewhat Mahadeo-like shape; the straight appendage of the circle is provided on each side with short projecting lines, alternately red and white, and almost producing the effect of the so-called herring-bone ornament. [Illustration: FIG. 69.--Petroglyphs in Lake county, Oregon.] Fig. 69, _c_ and _d_, executed in dark red, are other designs seen on the standing rock above mentioned. The colors, which, as the informant thinks, are rubbed in with grease, appear quite distinct on the dark surface of the rock. PENNSYLVANIA. Along the river courses in northern and western Pennsylvania many rocks are found bearing traces of carvings, though, on account of the character of the geological formations, some of them are nearly obliterated.
