While Ab had been occupied by home affairs trouble for him and his people had been brewing. By no means unknown to each other before the tiger hunt were Ab and Boarface. They had hunted together and once Boarface, with half a dozen companions, had visited the Fire Valley and had noted its many attractions and advantages. Now Boarface had gone away angry and muttering, and he was not a man to be thought of lightly. His rage over the memory of Ab's trophy did not decrease with the return to his own region. Why should this cave man of the West have sole possession of that valley, which was warm and green throughout the winter and where the wild beasts could not enter? Why had he, this Ab, been allowed to go away with all the tiger's skin? Brooding enlarged into resolve and Boarface gathered together his relations and adherents. "Let us go and take the Fire Valley of Ab," he said to them, and, gradually, though objections were made to the undertaking of an enterprise so fraught with danger, the listeners were persuaded. "There are other fires far down the river," said one old man. "Let us go there, if it is fire we most need, and so we will not disturb nor anger Ab, who has lived in his valley for many years. Why battle with Ab and all his people?" But Boarface laughed aloud: "There are many other earth fires," he said. "I know them well, but there is no other fire which chances to make a flaming fence about a valley close to the great rocks, and which has water within the space it surrounds and which makes a wall against all the wild beasts. We will fight and win the valley of Ab."
