We see, I suppose, the results of such a breakdown in Africa. Atlanteans were segregated there; isolated; and for a million years degenerated in that isolation to what they are. But their ancestors, before that segregation began, had better airships than we have; were largely giants, in more respects than the physical, were we are pygmies. Now they are--whatever may be their potentialities, whatever they may become--actually an inferior reace. And it is a racial stock that shows no signs of dying out. What then?--I suppose indeed there must be backward races, to house backward egos;--though for that matter you would think that our Londons and Chicagos and the rest, with their slums, would provide a good deal of accommodation. Or consider the Redskins, here and in South America: whether Atlanteans, or of some former subrace of the Fifth, at least not Aryans. Take the finest tribes among them, such as the Navajos. Here is a very small hereditary stream, kept pure and apart: of fine physique; potentially of fine mentality; unsullied with vices of any sort: a people as much nearer than the white man to natural spirituality, as to natural physical health. It is no use saying they are so few. Two millenniums ago, how many were the Anglo-Saxons? Three millenniums ago, how many were the Latins? Supposing the white race in America failed. The statistics of lunacy--of that alone--are a fearful _Mene, Tekel Upharsin_ written on our walls, for any Daniel with vision to read. I think Naure must also take into account these possibilities. Does she keep in reserve hereditary streams and racial stocks other than her great and main ones, _in case of accidents?_ Are the Redskins among these?
