It takes us a little less than 10 days of a fairly good journey to reach San Francisco. Dock at Oakland late in the evening. The next morning, after breakfast, the boxes and barrels with collections are taken on the dock--a big pile. Then the Santa Fe officials kindly run a flat freight car to the pile, the boxes, etc., are loaded on, the main part taken to the freight depot, the most valuable ones to express, shipped, and shortly after what remains of the expedition is on the Santa Fe Limited for Chicago. It only needs to be added that, notwithstanding the variety of receptacles and the difficulties of packing, the collections reached the Institution without damage to a single specimen. Thanks once more for the help received in making all safe to the captain and officers of the _Bear_, to Mr. Berg, the best of boatswains, to the carpenter, and to all those of the crew who assisted. THE YUKON TERRITORY--SITES, THE INDIANS, THE ESKIMO THE TANANA BRIEF HISTORICAL DATA The Tanana is the largest tributary of the Yukon. It is over 600 miles in length, and in its breadth, though not in its volume, it appears to equal, if not to exceed, the Yukon at their junction. The first white men to see the mouth of the Tanana were the Russian traders (about 1860), followed before long by the employees of the Hudson Bay Co. Dall says that it has long been noted on the old maps of Russian America, under the name of the River of the Mountain Men, while the Hudson Bay men called it the Gens-des-Buttes River. (Alaska and Its Resources, 281-282.) Dall mapped the junction of the river with the Yukon. The first who descended a part of its course were two traders, Harper and Bates, who reached the river higher up, sometime in the late seventies. The name of Harper is preserved by having been given to the big bend of the stream, 12 miles above its mouth. Its scientific exploration begins only in 1885, with the passage down nearly its entire length of Lieut. Henry T. Allen, United States Army;[5] the main work concerning the geography and geology of the river being done in 1898 by A. H. Brooks.[6] FOOTNOTES: [5] Allen, Henry T., Military Reconnaissance in Alaska.

Dall obtained an estimate of their whole number as about 150 families.[7] Petrof, in 1880, thought they numbered perhaps seven or eight hundred;[8] Allen in 1885 estimated them at between 550 and 600;[9] Brooks, in 1898, thought there were less than 400;[10] and the 1910 United States Census gives the total number of the "Tenan-kutchin," full bloods and mix bloods, as 415.[11]
