De Mailla tells us that the Shato were descended from the horde Chu yué of the Western Tu kiu (Chu yué was the family name of its chiefs, vide infra), who had settled to the south of the mountain Kin po shan, and to the east of the lake Pu lei hai (i.e. the Kukunor), and near the stream called Shato, whence they derived their name (op. cit. vol. vi. p. 378). Hyacinthe tells us they lived south of Kara Mannai Ola, in Khur-Kara-Ussu (Borgs, Hyacinthe, p. 277). He derives their name from the Mongol word Shato, meaning a leader (id.). De Guignes tells us the Chu yué Turks lived in the neighbourhood of lake Lop, near which was a great desert which the Turks called Shato, whence these Turks derived their name (cf. Hist. des Huns, vol. ii. p. 37). Like Klaproth, De Guignes identifies them with the Ta ghaz ghaz, a view to which I shall revert in a future paper on the Uighurs. De Guignes tell us the Shato horde was subject to the Great Khans of the Western Turks, and assisted them in their various expeditions.
