In the round that followed, Bart's warning was amply justified. Rabig in one of the clinches, as he leaned on Frank's shoulder, tried to bite and he butted continually. "Cut that out, Rabig," warned Frank in a low tone, after the latter had twice used his head as a battering ram. "My patience won't last forever." "I'll get you yet!" gasped Rabig. Once more he drove his head at Frank's chin and the latter, now thoroughly aroused by the foul tactics, let fly his right and caught his burly adversary fairly on the point of the jaw. Down went Rabig like a shot. Frank generously reached out his hand to help him to his feet, but Rabig struck it away and just here Corporal Wilson intervened. "That'll do," he commanded. "We don't want any knockout. Sheldon wins." Frank with a smile and wave of the hand stripped off his gloves and left the platform, to be pounded and mauled in exultation by his admiring comrades. Meanwhile, Rabig slunk away followed by hisses and jeers at the foul tactics that after all had only resulted in the beating he so richly deserved. "You trimmed him good, Frank," cried Tom exultantly. "You went around him like a cooper around a barrel," jubilated Billy. "I guess if you owed him anything, you've paid the score," chuckled Bart. "I've been aching for months to see that bully get what was coming to him." "I didn't want to hurt him," said Frank, good-naturedly. "But when he came butting at me that way and even trying to bite, I simply had to lace him. But even now I haven't a bit of grudge against the fellow." "He'll sing small after this," prophesied Tom. "But all the same, Frank, keep your weather eye open. He'll do you a mischief if he ever gets the chance." It was just after the noonday mess the next day, and the boys were chatting in front of the mill, when Frank, looking carelessly down the road, gave a startled exclamation. "Look what's coming, fellows!" he cried. They came up all standing and looked in the direction indicated. "By the great horn spoon!" ejaculated Tom. "Have I got the delirium tremens?" "It's a nightmare," declared Billy. Up the dusty road was coming the weirdest creation that the boys had ever seen. It looked like a great hulking rhinoceros. It moved along slowly and ponderously, as though it were straining under a burden too heavy to be borne. The sun reflected from its sides showed that it was coated with metal. There were openings in the armor through which the muzzles of machine guns protruded. Around its huge wheels there passed what seemed to be a broad endless chain that formed a path on which the wheels traveled. There was no driver to be seen and it came lumbering along like a blind monster feeling its way. But although its progress was leisurely it was sure, and the boys as they watched it gathered an impression of almost irresistible force. "I've read of the car of Juggernaut," muttered Tom as it came nearer, "and I guess this must be it."
