The hero in the above case could not wish his opponents metamorphosed directly, he could not wish this whenever he pleased or wherever he met the great company; he had to induce them to enter the house, which he turned by his wish into flint and then heated. When the moment of terrible anguish came on them, the true nature of each of those people grew evident; each head burst open, and out sprang the real person. All those of the first people whose minds had been modified, who, so to speak, had grown specialized internally, who were different from that which they had been to start with, were forced to change also externally, and could not escape or avoid that great power whose shadow was approaching; their destiny was on them, and they felt it. In the Wintu system, one of the two which are set forth in this volume, nearly all changes were effected by Olelbis; but there are examples of agents with other means. Tulchuherris turns old Tichelis into a ground-squirrel at the climax of his perfidy. He changes Hawt, the porter at the dangerous river, into a lamprey eel, whose children are to be eaten by Indians in the future. Old Sas, the false and vain chief in Saskewil, is beaten by his son-in-law, and receives his present form of sun and moon at the end of a long and bitter struggle, in which strength, wit, and keenness use the very last of their resources. There are cases in which some of the first people are so modified mentally that they are conscious of what has happened within them. They are ready for the change, they are willing to undergo it; but there is no immediate occasion, no impending struggle in which an opponent could have the chance to transform them. These people transform themselves by the utterance of a wish, and produce their own metamorphoses. There are still others who know, as do all, that a new race is coming, that they will be changed when it comes unless they are changed some time earlier. They know that they must be changed as soon as they see the new people or a sign or a mark of their coming. These unchanged first people, few in number comparatively, attempt to escape; but their attempts are vain, their efforts are useless. In the distant east they see smoke from the fires of the advancing new people, the Indians of America, or hear the barking of the dogs of this people, and that instant they receive the forms which are due them. Others escape for a season and hide in dark places; but the Indians go everywhere, and the metamorphoses continue till the career of the first people is ended.
