Mentally the Gilyaks take a low position--H. Lansdell thought the lowest of any people he had met in Siberia[646]. Despite the zeal of the Russian missionaries, and the inducements to join the fold, they remain obdurate Shamanists, and even fatalists, so that "if one falls into the water the others will not help him out, on the plea that they would thus be opposing a higher power, who wills that he should perish.... The soul of the Gilyak is supposed to pass at death into his favourite dog, which is accordingly fed with choice food; and when the spirit has been prayed by the shamans out of the dog, the animal is sacrificed on his master's grave. The soul is then represented as passing underground, lighted and guided by its own sun and moon, and continuing to lead there, in its spiritual abode, the same manner of life and pursuits as in the flesh[647]." A speciality of the Gilyaks, as well as of their Gold neighbours, is the fish-skin costume, made from the skins of two kinds of salmon, and from this all these aborigines are known to the Chinese as _Yupitatse_, "Fish-skin-clad-People." "They strip it off with great dexterity, and by beating with a mallet remove the scales, and so render it supple. Clothes thus made are waterproof. I saw a travelling-bag, and even the sail of a boat, made of this material[648]." Like the Ainu, the Gilyaks may be called bear-worshippers. At least this animal is supposed to be one of their chief gods, although they ensnare him in winter, keep him in confinement, and when well fattened tear him to pieces, devouring his mangled remains with much feasting and jubilation. Since the opening up of Korea, some fresh light has been thrown upon the origins and ethnical relations of its present inhabitants. In his monograph on the Yellow Races[649] Hamy had included them in the Mongol division, but not without reserve, adding that "while some might be taken for Tibetans, others look like an Oceanic cross; hence the contradictory reports and theories of modern travellers." Since then the study of some skulls forwarded to Paris has enabled him to clear up some of the confusion, which is obviously due to interminglings of different elements dating from remote (neolithic) times. On the data supplied by these skulls Hamy classes the Koreans in three groups:--1. The natives of the northern provinces (Ping-ngan-tao and Hienking-tao), strikingly like their Mongol [Tungus] neighbours; 2. Those of the southern provinces (Klingchang-tao and Thsiusan-lo-tao), descendants of the ancient Chinhans and Pien-hans, showing Japanese affinities; 3. Those of the inner provinces (Hoanghae-tao and Ching-tsing-tao), who present a transitional form between the northerns and southerns, both in their physical type and geographical position[650].
