Grave No. 21. Cremation rectangle last explored on the terrace near the mouth of the Naches River and situated 300 feet northwest from the two bridges. The rectangular enclosure was bounded by a single row of stones, but on the south several rows were placed outside to conform with the slope of the hill covering a semi-circular area, while on the west was a second row of marking stones. It was 12 feet long north and south by 8 feet wide east and west and 3 feet, 6 inches deep. Part of a child's skull, two scapulae, two tibiae, and a piece of a femur of another child; bones of a young adult; a small piece of skull and part of a femur of an adult were found. All the bones were in a poor state of preservation. Numbers 202-8188 to 202-8189 were found in this grave. 202-8188. Dentalium shells. 202-8189. A shell ornament was found in this excavation.

A grave 600 feet up on the plateau south of Oak Spring Canon, in a dome-shaped mound of volcanic ash left by the wind. It was not like a rock-slide grave. Somewhat angular stones unlike rock-slide material among which were no pebbles, formed a rectangular pile, 15 feet long by 12 feet wide. The grave contained many stones, several modern beads, evidently part of a rosary, two dentalium shells and a human lower jaw, but all were discarded. * * * * * Grave No. 24. This grave was located in a dome of volcanic ash on the hill or plateau north of the Ahtanum River and northwest of Mr. A. D. Eglin's house near Tampico. It was marked by a rectangular group of rough and wind smoothed rocks (not rock-slide or river pebble) which extended down as in the crude cairns, 6 feet northeast and southwest by 4 feet wide northwest and southeast, the vault being 5 feet by 3 feet. Numbers 99-4323 and 202-8190 were found in this grave.
