after the time of Alexander the Great there are few traces of any Aryan or Semitic, much less of Hamitic influence. All such influences were still in another world, separated by mountains, deserts, and wild nomadic tribes until that time. The Chinese seem to have made their civilization spontaneously and unassisted. Some recent writers suppose indeed a connection with ancient Sumeria. Of course both China and Sumeria arose on the basis of the almost world-wide early Neolithic culture, but the Tarim valley and the lower Euphrates are separated by such vast obstacles of mountain and desert as to forbid the idea of any migration or interchange of peoples who had once settled down.
But though the civilization of China is wholly Mongolian (as we have defined Mongolian), it does not follow that the northern roots are the only ones from which it grew. If it grew first in the Tarim valley, then unlike all other civilizations (including the Mexican and Peruvian) it did not grow out of the heliolithic culture. We Europeans know very little as yet of the ethnology and pre-history of southern China. There the Chinese mingle with such kindred peoples as the Siamese and Burmese, and seem to bridge over towards the darker Dravidian peoples and towards the Malays. It is quite clear from the Chinese records that there were southern as well as northern beginnings of a civilization, and that the Chinese civilization that comes into history 2000 years b.c. is the result of a long process of conflicts, minglings, and interchanges between a southern and a northern culture of which the southern may have been the earlier. The southern Chinese perhaps played the rôle towards the northern Chinese that the Hamites or Sumerians played to the Aryan and Semitic peoples in the west, or that the settled Dravidians played towards the Aryans in India. They may have been the first agriculturists and the first temple builders. But so little is known as yet of this attractive chapter in pre-history, that we cannot dwell upon it further here.
The chief foreigners mentioned in the early annals of China were a Ural-Altaic people on the north-east frontier, the Huns, against whom certain of the earlier emperors made war.
Chinese history is still very imperfectly known to European students, and our accounts of the early records are particularly
