To conclude: Our mode of reconciling the Mosaic history of antediluvian man with the disclosures of the gravels and caves would be to identify Palaeocosmic man, or man of the mammoth age, with antediluvian man; to suppose that the changes which closed his existence in Europe as well as Western Asia were those recorded in the Noachian deluge; and that the second colonization of the diminished and shrunken Europe of the modern period was effected by the descendants of Noah. It may be asked--Must we suppose that the Adam of the Bible was of the type of the coarsely featured and gigantic men of the European caverns? I would answer--Not precisely so; but it is quite possible that Adam may have been Turanian in feature. We should certainly suppose him to have been a man well developed in brain and muscle. Such men as those found in the caves would rather represent the ruder "Nephelim," the "giants that were in those days," than Adam in Eden. Farther, the new colonists of Europe after the deluge would no doubt be a very rude and somewhat degenerate branch of Noachidae, probably driven before more powerful tribes in the course of the dispersion. The higher races of both periods are probably to be looked for in Western Asia; but even there we must expect to find cave men like those whose remains were found by Tristram in the caves near Tyre, and like the Horim of Moses; and we must also expect to find the antediluvian age in the main an age of stone everywhere, and its arts, except in certain great centres of population, perhaps not more advanced than those of the Polynesians, or those of the agricultural American tribes before the discovery of America by Columbus. As a geologist, and as one who has been in the main of the school of Lyell, and after having observed with much care the deposits of the more modern periods on both sides of the Atlantic, I have from the first dissented from those of my scientific brethren who have unhesitatingly given their adhesion to the long periods claimed for human history, and have maintained that their hasty conclusions on this subject must bring geological reasoning into disrepute, and react injuriously on our noble science. We require to make great demands on time for the prehuman periods of the earth's history, but not more than sacred history is willing to allow for the modern or human age. CHAPTER XV.
