Examples like these might be adduced in any number. We might show how, in magic, negroes of Barbadoes make clay effigies of their enemies, and pierce them, just as Greeks did in Plato's time, or the men of Accad in remotest antiquity. We might remark the Australian black putting sharp bits of quartz in the tracks of an enemy who has gone by, that the enemy may be lamed; and we might point to Boris Godunof forbidding the same practice among the Russians. We might watch Scotch, and Australians, and Jews, and French, and Aztecs spreading dust round the body of a dead man, that the footprints of his ghost, or of other ghosts, may be detected next morning. We might point to a similar device in a modern novel, where the presence of a ghost is suspected, as proof of the similar workings of the Australian mind and of the mind of Mrs. Riddell. We shall later turn to ancient Greece, and show how the serpent-dances, the habit of smearing the body with clay, and other odd rites of the mysteries, were common to Hellenic religion, and to the religion of African, Australian, and American tribes. Now, with regard to all these strange usages, what is the method of folklore? The method is, when an apparently irrational and anomalous custom is found in any country, to look for a country where a similar practice is found, and where the practice is no longer irrational and anomalous, but in harmony with the manners and ideas of the people among whom it prevails. That Greeks should dance about in their mysteries with harmless serpents in their hands looks quite unintelligible. When a wild tribe of Red Indians does the same thing, as a trial of courage, with real rattlesnakes, we understand the Red Man's motives, and may conjecture that similar motives once existed among the ancestors of the Greeks. Our method, then, is to compare the seemingly meaningless customs or manners of civilised races with the similar customs and manners which exist among the uncivilised and still retain their meaning. It is not necessary for comparison of this sort that the uncivilised and the civilised race should be of the same stock, nor need we prove that they were ever in contact with each other. Similar conditions of mind produce similar practices, apart from identity of race, or borrowing of ideas and manners.
