These remainsare now all in the possession of the United States National Museum. At midnight, on July i. we returned to Nizhni Kolymsk, and five days laterour schooner left on the return trip. I reached Nome on September 17, andSeattle on October 9. Between Cape Big Baranoff and Chaun Bay a few more fossils were addedto the collection. Some of them were found on the base of the elevated tundrasilts facing the ocean, on many places between mountain ridges. The eleva-tions of this tundra beach difTer greatly according to locality. The surface of. Fig. 52.—Tundra beach near Chaun Bay. This picture shows detail of centralpart of figure 51, which compare. Fossils found here. the frozen tundra was in August, 1915, overgrown with luxuriant Arcticgrasses and herbs. The driftwood found along the beach comes from distantlocalities and has been brought down by the large rivers of the north. Inmany instances it is even undoubtedly of American origin. Some of these fossils—among them a fairly complete mammoth skull—were found in little cross gulches dug by small water courses. Mr. J. W. Gidley, in charge of fossil mammals in the NationalMuseum, reports that the collection of bones sent in by the Siberianexpedition contains a few fine specimens together with a considerablenumber of isolated bones which are valuable for study and com-parison. They all indicate a late Pleistocene age, as the bones ofmany of the forms represented can with difficulty be distingu
