This conflict of races which has left its traces in the Clyde valley apparently occurred in other parts of Europe. Everywhere the new race imposed its language and its customs upon the old, and everywhere its appearance is associated with a change and a rise in culture. It is presumed by the majority that this Alpine race brought with it the use of bronze, and was therefore at a higher level than Mediterranean man, but Prof. Sergi believes that the appearance of bronze and of the new race simultaneously was a mere coincidence, and that the Mediterranean race itself originated the use of metals. Meantime there is no means of deciding this question, which in any case is not of supreme importance, but what seems clear is that everywhere, except in the Mediterranean basin, the new race pressed the old one hard, whether by its skill in the arts of peace or in those of war remains uncertain. Even in the Mediterranean the old languages went down before that of Alpine man. In the Mediterranean area the new-comers seized the upland regions, that is, as we have suggested, the regions of pasture, and ousted the longheads permanently from them. In Spain and Portugal, perhaps because of the vicinity of the reservoir of the race in North Africa, Mediterranean man kept his hold, and the brachycephalic forms did not succeed in obtaining much foothold. But they are strongly represented in parts of southern France. In southern Italy, in Sicily, Corsica and Sardinia Mediterranean man largely kept out the intruders, though they appear again on the Alpine slopes of the north of Italy. But in the eastern Mediterranean the dark longheads are hard pressed and have kept little save the seaboard from the broadheads. Outside the Mediterranean area, the success of Alpine man was more checkered, but we are met with the difficulty that here a third race supervened later, so that existing conditions are not necessarily comparable to earlier conditions.
