Far back in the history of Europe and of our own country—or rather, we should say, in periods entirely pre-historic—it is now known that a similar disappearance of a human race has taken place. Celt and Teuton, we fancy, were the first occupiers of Europe,—but the case is not so. A wave or waves of population had preceded even them; and as we dig down into the soil beneath us, ever and anon we come upon strange and startling traces of those primeval occupants of the land. In those natural museums of the past, the caves and peat-bogs of Europe, the keen-witted archæologists of present times are finding abundant relics of a race dissimilar from all the human varieties of which written history takes cognisance. The researches of Wilson among the peat-bogs of the British Isles have brought to light traces of no less than two distinct pre-Celtic races inhabiting the land,—one of which had the skull of a singularly broad and short, square and compact form, while the head of the other race was long and very narrow, or “boat-shaped.” The exhumations of Retzius show that precisely similar races once inhabited Scandinavia. The caves and ossuaries of Franconia and Upper Saxony prove that in Central Europe, also, there were races before the advent of the Celts; and the researches of Boucher de Perthes, amid the alluvial stratifications of the river Somme, indicate a not less ancient epoch for the cinerary urns, bones, and instruments of a primordial people in France. “Here,” says M. de Perthes, “we naturally inquire, who were these mysterious primitive inhabitants of Gaul? We are told that this part of Europe is of modern origin, or at least of recent population. Its annals scarcely reach to twenty centuries, and even its traditions do not exceed two thousand five hundred years. The various people who are known to history as having occupied it—the Gauls, the Celts, the Veneti, Ligurians, Iberians, Cimbrians, and Scythians have left no vestiges to which we can assign that date. The traces of those [originally] nomadic tribes who ravaged Gaul scarcely precede the Christian era by a few centuries. Was Gaul, then, a desert, a solitude, before this period? Was its sun less genial, or its soil less fertile? Were not its hills as pleasant, and its plains and valleys as ready for the harvest? Or, if men had not yet learned to plough and sow, were not its rivers filled with fish, and its forests with game? And, if the land abounded with everything calculated to attract and support a population, why should it not have been inhabited? The absence of great ruins, indeed, indicates that Gaul at this period, and even much later, had not attained a great degree of civilisation, nor been the seat of powerful kingdoms; but why should it not have had its towns and villages?—or rather, why should it not, like the steppes of Russia, the prairies and virgin forests of
