Observant travellers have often been impressed by this progressive conformity of the Mongolo-Turki to Europeans. During his westward journey through Central Asia Younghusband, on passing from Mongolia to Eastern Turkestan, found that the people, though tall and fine-looking, had at first more of the Mongol cast of feature than he had expected. "Their faces, however, though somewhat round, were slightly more elongated than the Mongol, and there was considerably more intelligence about them. But there was more roundness, less intelligence, less sharpness in the outlines than is seen in the inhabitants of Kashgar and Yarkand." Then he adds: "As I proceeded westwards I noticed a gradual, scarcely perceptible, change from the round of a Mongolian type to a sharper and yet more sharp type of feature.... As we get farther away from Mongolia, we notice that the faces become gradually longer and narrower; and farther west still, among some of the inhabitants of Afghan Turkestan, we see that the Tartar or Mongol type of feature is almost entirely lost[673]." To complete the picture it need only be added that still further west, in Asia Minor, the Balkan Peninsula, Hungary, and Finland, the Mongol features are often entirely lost. "The Turks of the west have so much Aryan and Semitic blood in them, that the last vestiges of their original physical characters have been lost, and their language alone indicates their previous descent[674]." Before they were broken up and dispersed over half the northern hemisphere by Mongol pressure from the east, the primitive Turki tribes dwelt, according to Howorth, mainly between the Ulugh-dagh mountains and the Orkhon river in Mongolia, that is, along the southern slopes and spurs of the Altai-Sayan system from the head waters of the Irtysh to the valleys draining north to Lake Baikal. But the Turki cradle is shifted farther east by Richthofen, who thinks that their true home lay between the Amur, the Lena, and the Selenga, where at one time they had their camping-grounds in close proximity to their Mongol and Tungus kinsmen. There is nothing to show that the Yakuts, who are admittedly of Turki stock, ever migrated to their present northern homes in the Lena basin, which has more probably always been their native land[675].
