given by the native suggest that to his mind the form of the design is a result of attempts to represent by means of decorative art a certain idea. We have seen that this can not be the true history of the design, but that it probably originated in an entirely different manner. What is true in the case of decorative art is true of other ethnic phenomena. The historical explanation of customs given by the native is generally a result of speculation, not by any means a true historical explanation. The mythical explanation of rites and customs is seldom of historical value, but is generally due to associations formed in the course of events, while the early history of myths and rite must be looked for in entirely different causes, and interpreted by different methods. Native explanations of laws, of the origin of the form of society, must have developed in the same manner, and therefore can not give any clew in regard to historical events, while the association of ideas of which they are the expression furnishes most valuable psychological material.
