"Bang! rat-tat-tat! whack!" sounded from the schoolhouse, and the faces of the younger children paled. The noon hour had reached its end, and the schoolmaster was sounding his usual call. No bells summoned the pupils at this rural place of learning, but instead, at recess and at noon time the pedagogue came to the door and hammered loudly with his ruler upon the clapboards there beside him. Very grim was this same schoolmaster, and unfortunate was the pupil who came into the room a laggard after that harsh summons had rung out across the fields and flats. There stood the schoolmaster--he could be seen from the Red Revenger--and it was not difficult even at that distance to imagine the ominous look upon his face. Again and again came forth the wooden call, and then the schoolmaster stepped out into the roadway. He looked about inquiringly. He came to the top of the hill, from whence, off in the flats, the jumper and its load were plainly seen, and then he paused. It was clear that he was puzzled and was meditating. He called out hoarsely: "What do you mean? What are you doing? Come in, and come now!" There was no mistaking the quality of that sharp summons. It meant business, and in all probability it meant trouble, too, for somebody; trouble of strictly personal, as well as of a physical character. There was no reply for a moment, and then Billy, the reprobate, grinning again at Jack, and giving to his voice a tone intended to be a compound of profound respect and something like unlimited despair, bawled out: "We can't!" The teacher descended the hill with all firmness and sedateness; he looked like a ramrod, or a poker, or anything stiff and straight, and suggestive of unpleasantness. He followed the roadway until just opposite the jumper, and then surveying the scene with an angry eye, commanded all to return to the schoolhouse on the moment. Here the situation became acute. It was Jack's turn now to make things clear. That villain rose to the occasion gallantly. He shouted out an explanation of how the jumper had happened, by the merest accident in the world, to leave the roadway, and had gone out so far upon the India-rubber ice; how the final catastrophe had taken place, and how helpless they all were in their present condition. The road could be reached only by a wade of a hundred yards through two feet deep of ice water--more in places--breaking the ice as an advance was made. It would be an awful undertaking, the death almost of the little children, and dangerous to all. What should they do? And the rascal's voice grew full of trouble and apprehension. Fortunately for him, the teacher was too far off to note the expression on his face. The czar of winter did not wait long. He started off, and was over the hill again and out of sight within the next three minutes, and it was clear that he was going somewhere for assistance. Then some of the other boys wanted to know what was to be done, and Billy looked at Jack inquiringly.
