whatever new form of danger might lurk in this strange, new world. Had he had any conception of a life after death he would doubtless have felt assured that the earthquake had killed him and that he was now wandering through the heavenly vale; but the men of Nu's age had not yet conceived any sort of religion, other than a vague fear of certain natural phenomena such as storms and earthquakes, the movements of the sun and moon, and those familiar happenings which first awake the questionings of the primitive. He saw the sun; but to him it was a different sun from the great, swollen orb that had shone through the thick, humid atmosphere of the Niocene. From Oo's lair only the day before he had been able to see in the distance the shimmering surface of the restless sea; but now as far as eye could reach there stretched an interminable jungle of gently waving tree tops, except for the rolling plain at his feet where yesterday the black jungle of the ape-people had reared its lofty fronds. Nu shook his head. It was all quite beyond him; but there were certain things which he could comprehend, and so, after the manner of the self-reliant, he set about to wrest his livelihood from nature under the new conditions which had been imposed upon him while he slept. First of all his spear must be attended to. It would never do to trust to that crude patch longer than it would take him to find and fit a new haft. His meat must wait until that thing was accomplished. In the meantime he might pick up what fruit was available in the forest toward which he was bending his steps in search of a long, straight shoot of the hard wood which alone would meet his requirements. In the days that had been Nu's there had grown in isolated patches a few lone clumps of very straight, hard-wood trees. The smaller of these the men of the tribe would cut down and split lengthways with stone wedges until from a single tree they might have produced material for a score or more spear shafts; but now Nu must see the very smallest of saplings, for he had no time to waste in splitting a larger tree, even had he had the necessary wedges and hammers. Into the forest the youth crept, for though a hundred thousand years had elapsed since his birth he was still to all intent and purpose a youth. Upon all sides he saw strange and wonderful trees, the likes of which had never been in the forests of yesterday. The growths were not so luxuriant or prodigious, but for the most part the trees offered suggestions of alluring possibilities to the semiarboreal Nu, for the branches were much heavier and more solid than those of the
