“Sometime there will come a day when we ourselves shall have to give place to a new thing. Very certainly we shall struggle against the inevitable just as these remnants of the Old People do. We shall try with all our strength to grind it back into the earth from which it is emerging, for treachery to one’s own species must always seem a crime. We shall force it to prove itself, and when it does, we shall go; as, by the same process, these are going.”
