Now that he had accomplished the main object of his labor Frank could devote his energies toward his own escape. When the bull passed him he turned and bolted in the direction of the friendly fence. The distance was too great to think of making it in one run. As he flew along he expected to hear the pounding of the bull's hoofs on the hard turf behind him, nor was he mistaken. "He's coming, Frank! Oh! be careful!" Minnie was calling this in trembling tones, and yet Frank paid little or no attention to her warning, for he had to depend upon his own instincts just then. At the proper instant he whirled around. Already he had stamped the situation in his mind, and knew to a fraction just how far away the fence lay. Again he managed to escape the rush of the beast. Had he been an experienced Spanish bull-fighter he could hardly have done better. And again he changed his position. All he wanted was one more chance, and he knew he could win out. This time the animal, growing more and more enraged, came within a foot of striking the boy, who was beginning to get winded with his efforts. "Now!" cried Minnie, who seemed to recognize the opening when it appeared. Already was Frank in full motion, sprinting for the near-by fence with all his might and main. He reached it even as the bull was bearing down after him. One tremendous effort and he had mounted the rails to fall in a heap on the other side--safe! The bull came to a sudden halt within the enclosure, and vented his fury in more bellowing and tearing up of the turf. Minnie was at the side of her champion in a moment. "Oh! Frank, are you hurt?" she exclaimed, as she caught hold of him in her anxiety; and almost breathless as he was, the boy could not help feeling a thrill of satisfaction at the prospect of the breach between them being healed in this wonderful manner. "Not a bit, Minnie, only short of breath. Here's your sweater, safe and sound. Excuse me for taking it in that rude way, but you see there wasn't much time for explanations," he managed to say, as he started to put it on her again, an operation to which she submitted with pleasure. "And now," said Frank, as arm in arm they started to walk away from the scene of the adventure, he rolling his wheel as he went, "what was all this trouble about, Minnie? What terrible thing have I done to make you treat both Helen and myself so? Neither of us have the least idea, and she's very unhappy over it. Please let me know." Minnie looked troubled, and yet a gleam of hope began to appear in her gray eyes. "Oh! if you only could explain it away, I'd be so glad, Frank; so glad," she said. "Is it anything that Lef Seller has been saying about me?" he asked, shortly.
