内容简介：
One Saturday afternoon in January a lively and animated group of boys were gathered on the western side of a large pond in the village of Groveton. Prominent among them was a tall, pleasant-looking young man of twenty-two, the teacher of the Center Grammar School, Frederic Hooper, A. B., a recent graduate of Yale College. Evidently there was something of importance on foot. What it was may be learned from the words of the teacher.
