About the man of this period I must say something, as he in his day lived in countless swarms on this elevated land. He may have lived also in the valleys of the lowlands, but his traces there have been obliterated by the plough. First of all as to his personal appearance. He was dark-haired, tall, and his head was long, like that of a new-born child, or boat-shaped, a form that disappears with civilisation, and resolves itself into the long face instead of the long head. At some period, vastly remote, a great migration of a long-headed race took place from Central Asia. It went forth in many streams. One to the east entered Japan; probably the Chinese and Anamese represent another. But we are mainly concerned with the western outpour. It traversed Syria, and Gilead and Moab are strewn with its remains, hut circles, dolmens, and menhirs identical with those on Dartmoor. Hence one branch passed into Arabia, where, to his astonishment, Mr. Palgrave lighted on replicas of Stonehenge.[5] Another branch threw itself over the Himalayas, and covered India with identical monuments. Again another turned west; it traversed the Caspian and left innumerable traces along the northern slopes of the Caucasus. The Kuban valley is crowded with their dolmens. They occupied the Crimea, and then struck for the Baltic. That a branch had passed through Asia Minor and Greece, and constituted itself as the Etruscan power in Italy, is probable but not established. The northern stream strewed Mecklenburg and Hanover with its remains, occupied Denmark and Lower Sweden, crossed into Britain, and took complete possession of the British Isles. Other members of the same swarm skirted the Channel and crowded the plateaux and moors of Western and Central France with their megalithic remains. The same people occupied Spain and Portugal, the Balearic Isles, Corsica and Sardinia, and Northern Africa, and are now represented by the Koumirs and Kabyles. To this race the name of Iberian, Ivernian, or Silurian has been given. It contributed its name to Ireland (Erin or _Ierne_), where it maintained itself, but was known to the conquering Gaels as the Tuatha da Danann and Firbolgs, two branches of the same stock. The name of Damnonia given to Devon is probably due to these same Danann, who were also found in the south of Scotland. When this great people reached Europe, Japan, India, Africa, before its branches had begun to ramify to east and west, to south and north, its religious doctrines and its practices had become stereotyped, and almost ineradicably ingrained into the consciousness of the entire stock. If we desire to understand what their peculiar views were, what were the dominant ideas which directed their conduct, and which led them to erect the monuments which are marvels to us, even at the present day, we must go to China.
