plays an essential part. It will be seen that literary tales, such as those of Hans Andersen and Lord Brabourne, based though they often are upon tradition, are excluded from Fairy Tales as thus defined. Much no doubt might be said both interesting and instructive concerning these brilliant works. But it would be literary criticism, a thing widely different from the scientific treatment of Fairy Tales. The Science of Fairy Tales is concerned with tradition, and not with literature. It finds its subjects in the stories which have descended from mouth to mouth from an unknown past; and if reference be occasionally made to works of conscious literary art, the value of such works is not in the art they display, but the evidence they yield of the existence of given tales in certain forms at periods and places approximately capable of determination: evidence, in a word, which appropriates and fixes a pre-existing tradition. But even in this they are inferior in importance to historical or topographical works, where we frequently meet with records of the utmost importance in considering the origin and meaning of Folk-tales.
Literature, in short, of whatever kind, is of no value to the student of Fairy Tales, as that phrase is here used, save as a witness to Tradition. Tradition itself, however, is variable in value, if regard be had alone to purity and originality. For a tribe may conceivably be so isolated that it is improbable that any outside influence can have affected its traditions for a long series of generations; or on the other hand it may be in the highway of nations. It may be physically of a type unique and unalloyed by foreign blood; or it may be the progeny of a mingling of all the races on the earth. Now it is obvious that if we desire to reason concerning the wide distribution, or the innate and necessary character of any idea, or of any story, the testimony of a given tribe or class of men will vary in proportion to its segregation from other tribes and classes: where we can with most probability exclude
