_Fortifications._ A so-called "Indian fort" is situated near Rock Creek about six miles below Rock Lake. It is about a mile south of the ranch of Mr. Frank Turner (p. 54), and shown in the photographs reproduced in Figs. 1[243] and 2[244], Plate VI. These were taken and presented by Mr. J. S. Cotton, then in charge of the cooperative range work at the Washington State Experiment Station at Pullman, who furnished from his notebook all our data on this subject. The "fort" is built on a flat knoll of about fifteen feet in height and with precipitous sides. It is in the form of a circle, being enclosed about four fifths of the way around. The wall is built of flat rocks which are tilted in such a manner that they will glance all projectiles into the air. There were numerous arrow chip pings within the "fort." There are many Indian graves supposed to be very old, two pits believed to mark building sites, and a long line of stones in the vicinity (pp. 140, 54, 29). [243] From the interior. [244] From the exterior. _Wounds._ The skull of skeleton No. 99-4318, found in rock-slide grave No. 10 (5) on the north side of the Naches River half a mile above its mouth, showed where the right side of the orbit had been pierced in such a way that the malar bone was partly severed and repair had taken place, leaving a large anterior lateral projection on the malar bone. One rib had two articular surfaces at the anterior end. DRESS AND ADORNMENT. _Skins._ Tanned skin and skin bearing hair of animals, including the deer, and feathers of the woodpecker have been found in the graves and were evidently portions of garments or of pouches; but graves containing these materials are apparently more modern than some of the others. No skins of birds were found by us in this whole region. The scrapers mentioned on page 69 and the hammers as well possibly as the grooved stones mentioned on pages 30 and 75 may have contributed to the making of clothing: the former for scraping skins, the latter for beating and softening them.
