"I bet ye!" scoffed Wunpost; "but you can't tell _me_ that God Almighty was steering that waterspout. It just hit in Woodpecker Canyon, same as one hit Hanaupah last week and another one washed out down below. They're falling every day, but I'm going up into them hills, and do you reckon one will drop on me? Don't you think it--God Almighty has got more important business than following me around through the hills. I'm going to take my little dog, so I'll be sure to have Good Luck; and if I don't come back you'll know somebody has got me, that's all." He tightened his lash ropes viciously, mounted his horse and took the lead, followed by Old Walker and the other mules, packed; and when he whistled for Good Luck, to Billy's surprise the little terrier went bounding off after him. She waved at him furtively and tried to toll him back, but his devotion to his master was still just as strong as it had been when he had adopted him in Los Angeles. When he had been prostrated by the heat he had stayed with Billy gladly, but now that he was strong and accustomed to the climate he raced along after the mules. Wunpost looked back and grinned, then he reached down a hand and swooped his dog up into the saddle. "You can't steal him!" he hooted, and Billy bit her lip, for she thought she had weaned him from his master. And Wunpost--she had thought he was tamed to her hand, but he too had gone off and left her. He was still as wild and ruthless as on the day they had first met, when he had been chasing Dusty Rhodes with a stone; and now he was heading off into the high places he was so fond of, to play hide-and-seek with his pursuers. Several had come up already, ostensibly to view the ruin but undoubtedly to keep Wunpost in sight; and if he continued his lawless strife she doubted if the good Lord would preserve him, as He had from the cloudburst. Time and again he had mounted to go and each time she had held him back, for she had sensed some imminent disaster; and now, as he rode off, she felt the prompting again to run after him and call him back. But he would not come back, he was headstrong and unrepentant, making light of what others held sacred; and as she watched him out of sight something told her again that he was going out to meet his doom. Some great punishment was hanging over him, to chastise him for his sins and bring him, perhaps, to repentance; but she could no more stop his going, or turn him aside from his purpose, than she could control the rush of a cloudburst. He was like a force of nature--a rude, fighting creature who beat down opposition as the flood struck down bushes, rushing on to seek new worlds to conquer. CHAPTER XVIII A LESSON
