From what has thus been set forth, some general inferences of a comprehensive character are suggested. It is scarcely open to doubt that at a very early stage in the development of primitive mechanical art, the exceptional aptitude of skilled workmen was recognised and brought into use for the general benefit. Co-operation and some division of labour in the industrial arts, necessary to meet the universal demand for tools and weapons, appear also to have been recognised from a very remote period in the social life of the race. There were the quarriers for the flint, the obsidian, the shale, the pipestones, the favourite minerals, and the close-grained igneous rocks, adapted for the variety of implements in general use. There were also the traders by whom the raw material was transported to regions where it could only be procured by barter; as appears to be demonstrated by the repeated discovery, not only of flint and stone implements, alike in stray examples, and in well-furnished caches; but also of work-places, remote from any flint-producing formation, strewn with the chips, flakes, and imperfect or unfinished implements of the tool-makers. It thus becomes obvious that the men of the earliest Stone age transported suitable material for their simple arts from many remote localities, and purchased the services of the skilled workman with the produce of the chase, or whatever other equivalent they could offer in exchange. The further archæological search is extended, the evidence of social co-operation and systematised industry among the men of the Palæolithic era, as well as among those of later periods prior to the dawn of metallurgic skill, becomes more apparent. Nor is it less interesting to note that there was no more equality among the men of those primitive ages, than in later civilised stages of social progress. Diversities in capacity and consequent moral force asserted themselves in the skilled handicraftsmen of the Palæolithic dawn, much as they do in the most artificial states of modern society. As a natural concomitant to this, and an invaluable element of co-operation, the prized flint flakes appear to have furnished a primitive medium of exchange, more generally available as a currency of recognised value than any other substitute for coined money. The principles on which the wealth of nations and the whole social fabric of human society depend, were thus already in operation ages before the merchants of Tyre, or the traders of Massala, had learned to turn to account the mineral resources of the Cassiterides; or that vaguer and still more remote era before the ancient Atlantis had vanished from the ken of the civilised dwellers around the Mediterranean Sea. ----- [10] _Ancient Stone Implements_, p. 14.
