Then in other places we come across relics of ancient agricultural life preserved in these stories. In the Irish story of "Hairy Rouchy" the heroine is fastened by her wicked sisters in a pound,[59] an incident not mentioned in the parallel Highland tale related by Campbell.[60] Many Irish stories contain details of primitive life that the Scottish variants do not contain. The field that was partly cultivated with corn and partly pasture for the cow,[61] the grassy ridge upon which the princess sat, and the furrows wherein her two brothers were lying,[62] are instances. A great question arises here. If the Scotch story does not mention the primitive incident mentioned in the Irish story, does it mean that the Irish story has retained for a longer time the details of its primitive original? Or does it mean that it has absorbed more of surrounding Irish life into it than the Scotch story has of surrounding Scottish life? These details must have a place in the elucidation of Irish folk-tales, because they have a very distinct place indeed in primitive institutions; and it hence becomes a question to folklorists as to how they have entered into, or escaped from, the narrative of traditional story. It appears to me that the appearance or non-appearance of these phases of early life are typical of what has been going on with the plot and structure of folk-tales as long as they have remained the traditional treasures of the people. A story identical in all the main outlines of plot will be varied in matters of detail, according to the people who are using it in their daily routine of story-telling. But this variation is always from the primitive to the cultured, from the simple to the complex. The mud-cabin or cave-dwelling in Irish story would have developed into the palace in stories of a richer country like England; the old woman, young girl, master and servant, would become perhaps the queen, princess, king and vassal; just as in Spanish and Portuguese stories the giant of other European tales is represented by "the Moor." If this process of change is a factor in the life of the folk-tale, it follows that those folk-tales which contain the greatest number of primitive details are the most ancient, and come to us more directly from the prehistoric times which they represent.
