The interesting possibilities of this Color Theory in penology and in the regulation of domestic affairs, did not escape Leighton. He had himself believed that in the latest discoveries in physics there might be found a connecting link between the science of matter and the science of mind. His natural skepticism, however, did not allow him to accept too readily all of Sajipona's amazing statements. He doubted her real knowledge of these abstruse subjects. She spoke of these matters, indeed, crudely, not with the familiarity as to detail of a trained scientist. What she said had all the simplicity, and much of the fantastic absurdity, of a fairy tale. But beneath its extravagance there was enough substance to her story, and the theory upon which it was based, to make it worthy a scientist's consideration. For one thing, it changed completely the notion Leighton had already formed of this subterranean world. The story, for instance, of the chastened millionaire took into account a complex social system that was utterly unthinkable in a region so confined territorially, so limited, by reason of its peculiar situation, as regards human activity, as this so-called Land of the Condor. The inhabitants of the cave, from what he had seen of them--in the straggling village they had passed through with Narva, and among the followers of Raoul--gave no indication of a culture superior to that shown by people just emerging from savagery. These cavemen, certainly, had not reached that stage of enlightenment from which is developed the millionaire capitalist of whose interesting ventures in monopoly Sajipona had told them. In the ill-fated Anitoo, however, and his men, and in the people surrounding Sajipona, there was evidence of social and mental superiority. The two men who served as the queen's ambassadors in the garden, and who were distinguished from the rest by their red robes, belonged either to a priesthood, or to some order that placed them intellectually above the common rank. They were undoubtedly learned far beyond the Indian average. One of them, indeed, was with Sajipona in the court, and prompted her more than once during her explanation of the Radium Sun and its uses. He spoke in a low voice, and in a language unintelligible to the Americans. From his bearing and fluency of speech, Leighton concluded that he was one of the commonwealth's so-called "wise men," an investigator, possibly, in those physical and psychological phenomena that held out such tantalizing promise of new conquests in the domain of human knowledge.
