Flats again on both sides, but hills beyond, with just one little spot of snow. Will be warm day again. ANCIENT MAN Prospects of old remains of man all along the river are slight if any. Old silt flats have doubtless been mostly washed away (as now) and rebuilt. Only on the older parts, now often far from water, could anything remain and there it is all a jungle of forest with undergrowth, with all surface traces absent (no stone, no shell), and no one here to find things accidentally. As to the hills that approach the river, the slopes (shales, overlain by what looks like stratified mud and silt rock) are mostly of recent exposure, and have doubtless been receding slowly through erosion, so that the bank line along them is not old; and their valleys are few, narrow, and were higher formerly as well as more extended toward where the river flowed then. The only hopeful spot is about Hot Springs, where fossil animal remains are said to exist, but here nothing as yet has been noted suggesting ancient man. June 18, 4 p. m. River getting broader. Some low dunes. In distance a range of bluish hills before us--the hills along the Yukon. Boat meandering from side to side. Every now and then a necessary steam blow-out of mud, or a short whistle, hurry of a man over the top of the barge and of two half-breeds along its side to the prow to test, with long pointed and graduated poles, the depth of the water, calling it out to the captain. The calls range from "no bottom" to "4 feet," at the latter of which the boat begins to touch and back water. 5 p. m. Arrived at Tanana, a cheerful looking town, extending over about half a mile along the right bank of the Yukon, here about 20 feet high; but now, with the gold rush over, rather "slack" on both business and population, as are all other Yukon towns. Somewhat disappointed with the Yukon--not as majestic here as expected. See storekeeper--introduced by captain. Hear good news. The Indians have a big potlatch at the mission, 2 miles above. Tanana Indians expected. And there will be many in attendance. Rumors of this potlatch were heard before, but this was the first definite information. Get on a little motor boat with Indians who were making some purchases, and go to the St. Thomas Episcopal Mission, Mr. Fullerton in charge. THE INDIANS AT TANANA The mission above Tanana is beautifully located on the elevated right Yukon bank, facing Nuklukhayet island and point, the latter, according to old reports, an old trading and meeting spot of the Kuchin tribes, and the confluence of the Tanana with the Yukon. The mission house, located on rising ground, the wooden church lower down, the cemetery a bit farther up, and the Indian village a bit farther downstream, with their colors and that of the luxuriant vegetation, form a picturesque cluster.
