The original men who peopled the northern continents after the first glacial period were of small stature, agile, and well formed, with mild and pleasing countenance and heads of the medium (mesitocephalic) type. They were dwellers in a warm climate and subsisted on fruits. As population increased and men became hunters and fishermen, and wandered widely over the world, a large-boned, coarse-featured, and savage type of man arose, such as we find in the older caves and gravels, and weapons of kinds not needed in primitive times were invented. In this state of affairs, when the coarser and stronger races had made themselves masters of the world, and had perhaps partially intermixed with the older and more peaceful peoples, a great diluvial catastrophe occurred, which swept away the greater part of men. The survivors were of the old and unmodified stock, and it was they who repeopled the new world, finding possibly here and there some survivors of the former population, or themselves locally relapsing into a similar state. In this case all the seeming paradoxes and contradictions which have perplexed archæologists would be easily explained. We might even find occasional captives of the primitive small race among the interments of the old giants, and we might find new races of superior physical power arising in the new world and again intruding on the feebler race.
In closing our notice of this period we may proceed to connect it with actual history in the British Islands. When the Romans invaded Britain they found in it two races of men physically very distinct, one of them the aborigines, who had made their way to the island as its first population after the close of the mammoth age, the others apparently a later intrusion. They are known to English antiquaries from their modes of burial as the men of the long and the round barrows or funeral mounds. The first of these are beyond doubt the kinsmen of our little men of the Trou de Frontal, in Belgium. They are thus described by Greenwell and Taylor[29]:
[29] Greenwell, _British Barrows_; Taylor, _Origin of the Aryans_.
They were of feeble build, short stature, dark complexion, and somewhat long skull. They buried their dead in long barrows or mounds with interior chambers and passages; some of these are as much as 400 feet in length, and resemble artificial caves; and there can be no doubt that, as in Belgium, they buried their dead in caves when these were accessible; and the laborious construction of the long barrows when caves failed is an indication of the great importance they attached to the secure and decent sepulture of the dead. No trace of metal is found in their barrows, and but little pottery, but it is believed that they had at a very early time domesticated sheep and cattle and practised agriculture. These people are now identified with the people of the south and west of England, called by the Romans Silures. They were the builders of the cromlechs, dolmens, and other megalithic structures so common in various parts of the old continent. Their type survives to this day in the small dark people of parts of Wales and the south and west of Ireland, and in parts of the Hebrides. Their physical characters connect them with the primitive populations of the hills of Central France, with the Basques of the Pyrenees, the Corsicans, the Berbers of Africa, and the Guanches of the Canary Islands, and the term Iberian has been applied to the whole group. Their language was originally not Aryan, but Turanian. They represent not merely a new race still surviving, but a distinct advance in practical civilisation over that of the peoples of the palanthropic age, in Europe at least.
