Then a savage growl that sounded dulled and muffled broke out from the stable, and Frank felt a little quiver run through him. The sound died away and he found the heavy silence that followed it hard to bear, but a few moments later the dog growled again and then broke into a series of short, snapping barks. "If he gets loose somebody's going to be sorry," said Harry with a harsh, strained laugh. Then he gripped Frank's arm hard. "Look yonder!" A yellow blaze suddenly leaped up beside the barn and grew brighter rapidly, until Frank made out a man's black figure outlined against it. He seemed to be throwing an armful of brush or withered twigs upon the spreading fire, and Frank swung around toward his companion. "Hadn't we better shout or run down?" he asked. "Wait," said Harry shortly. "Dad's already on that fellow's trail." He was right, for while the figure bent over the fire a thin streak of red sparks flashed out from among the fruit trees and the crash of a rifle filled the clearing. The man leaped back from the fire, ran a few paces at headlong speed, and vanished suddenly into the shadow. "He's not hurt," Frank said hoarsely. "Then it's because dad didn't mean to hit him," Harry answered. "That was a warning." "He doesn't seem to be going to put out the fire." "No," said Harry with the same strained laugh, "dad knows too much for that. Those logs are thick, they won't light easy, and it's only a little pile of small stuff that's burning. Dad has no use for standing out where those fellows can see him unless it's necessary. In the meanwhile the dope men don't know where he is and that's going to worry them." Frank could understand this. It seemed very likely that the small fire would burn out before the logs caught, and it was clear that the men who had made it could not run back into the light to throw on more brushwood without incurring the hazard of being shot. On the other hand, Mr. Oliver would have to face the same peril if he approached to put it out. From this it seemed very probable that both he and the dope men would wait to see what the result would be. In the meanwhile the crash of the rifle had had a curious effect on Frank. It was the first time that he had ever seen a shot fired in anger and he was sufficiently well acquainted with Mr. Oliver's character to feel certain that if the warning failed to prove efficacious the next bullet would not go wide. He felt his nerves tingle and caught his breath more quickly, for it seemed highly probable that he might be shortly called on to watch or, perhaps, take part in some horrible thing. He did not mean to shirk it, but at the same time he was conscious that he would have greatly preferred to be standing beside the schooner's wheel while she lurched over the big foaming seas.
