the oldest artificial or professional class in the evolution of society. For sorcerers are found in every savage tribe known to us; and among the lowest savages, such as the Australian aborigines, they are the only professional class that exists. As time goes on, and the process of differentiation continues, the order of medicine-men is itself subdivided into such classes as the healers of disease, the makers of rain, and so forth; while the most powerful member of the order wins for himself a position as chief and gradually develops into a sacred king, his old magical functions falling more and more into the background and being exchanged for priestly or even divine duties, in proportion as magic is slowly ousted by religion. Still later, a partition is effected between the civil and the religious aspect of the kingship, the temporal power being committed to one man and the spiritual to another. Meanwhile the magicians, who may be repressed but cannot be extirpated by the predominance of religion, still addict themselves to their old occult arts in preference to the newer ritual of sacrifice and prayer; and in time the more sagacious of their number perceive the fallacy of magic and hit upon a more effectual mode of manipulating the forces of nature for the good of man; in short, they abandon sorcery for science. I am far from affirming that the course of development has everywhere rigidly followed these lines: it has doubtless varied greatly in different societies. I merely mean to indicate in the broadest outline what I conceive to have been its general trend. Regarded from the industrial point of view the evolution has been from uniformity to diversity of function: regarded from the political point of view, it has been from democracy to despotism. With the later history of monarchy, especially with the decay of despotism and its displacement by forms of government better adapted to the higher needs of humanity, we are not concerned in this enquiry: our theme is the growth, not the decay, of a great and, in its time, beneficent institution.
