While the idea, now being dimly suspected by some anthropologists, that man's mind is not the result of a _very long and slow_ development from the beast, is correct according to the records of Theosophy, we must remember that the incarnation of the "Manas" or Thinker, which made incomplete man into the perfect septenary he is today, took place long before the temporary decline of the "primitive" man after the disappearance of Atlantis. One eminent scientist at least, Professor F. Soddy, F. R. S., lecturer on physical chemistry and radio-activity at Glasgow University, has lately suggested that in his opinion some great civilization may have existed (long before the "primitive" Stone Ages) which ruined itself and descended into barbarism by the abuse of the power to disintegrate matter and so to release forces of terrible potency whose existence the discovery of the properties of radium has faintly revealed to us, but which we have, fortunately, not the slightest idea how to unloose. Theosophy tells us that something of the kind did happen; but the mind of man was even then long ages posterior to the time when the "Sons of Mind" settled into the forms which only then, properly, could be called mankind. For many years the existence of hundreds of giant portrait-statues on the wild volcanic Easter Island, two thousand miles from the coast of South America, has been known, and their origin and meaning is still one of the greatest of the world's enigmas. What was the mysterious race that carved them? How is it that such works, which obviously required the presence of a large and intelligent population, should be found on such a small island, so far from the continental lands? Archaeologists in general seem to avoid the problem; certainly no adequate theory has been advanced by the recognized authorities to meet the case. H. P. Blavatsky gave us the key to the mystery when she briefly described parts of the pre-Atlantean continent of Lemuria: Easter Island is an Atlantean vestige of that really primitive land whose truly primeval inhabitants were of larger proportions than ourselves. Well, lately we have seen three or four articles in different American and other magazines discussing the problem and trying to explain it upon the very lines of the Theosophical teachings, no other being considered reasonable.
