The Neolithic stage in culture is characterized by: (1) the presence of polished stone implements, and in particular the stone _axe_, which was perforated so as to be the more effectually fastened to a wooden handle, and which was probably used rather for working wood than in conflict. There are also abundant arrow heads. The fact that some implements are polished does not preclude the presence of great quantities of implements of unpolished stone. But there are differences in the make between even the unpolished tools of the Neolithic and of the Palæolithic Period. (2) The beginning of a sort of agriculture, and the use of plants and seeds. But at first there are abundant evidences that hunting was still of great importance in the Neolithic Age. Neolithic man did not at first sit down to his agriculture. He took snatch crops. He settled later. (3) Pottery and proper cooking. The horse is no longer eaten. (4) Domesticated animals. The dog appears very early. The Neolithic man had domesticated cattle, sheep, goats, and pigs. He was a huntsman turned herdsman of the herds he once hunted.[47] (5) Plaiting and weaving. These Neolithic people probably “migrated” into Europe, in the same way that the Reindeer Men had migrated before them; that is to say, generation by generation and century by century, as the climate changed, they spread after their accustomed food. They were not “nomads.” Nomadism, like civilization, had still to be developed. At present we are quite unable to estimate how far the Neolithic peoples were new-comers and how far their arts were developed or acquired by the descendants of some of the hunters and fishers of the Later Palæolithic Age. Whatever our conclusions in that matter, this much we may say with certainty; there is no great break, no further sweeping away of one kind of man and replacement by another kind between the appearance of the Neolithic way of living and our own time. There are invasions, conquests, extensive emigrations and intermixtures, but the races as a whole carry on and continue to adapt themselves to the areas into which they began to settle in the opening of the Neolithic Age. The Neolithic men of Europe were white men ancestral to the modern Europeans. They may have been of a darker complexion than many of their descendants; of that we cannot speak with certainty. But there is no real break in culture from their time onward until we reach the age of coal, steam, and power-driven machinery that began in the eighteenth century.
