They were gone till long after school began, and when they came back the teacher called them up, and waited for them to arrive slowly at his desk while he drew his long, lithe rod through his left hand. They had to own that they had done wrong, and they had no excuse but the one a boy always has--they forgot. He said he must teach them not to forget, and their punishment began; surely the most hideous and depraving sight, except a hanging, that could be offered to children's eyes. One of them howled and shrieked, and leaped and danced, catching his back, his arms, his legs, as the strokes rained upon him, imploring, promising, and getting away at last with a wild effort to rub himself all over all at once. When it came the hero's turn, he bore it without a murmur, and as if his fortitude exasperated him, the teacher showered the blows more swiftly and fiercely upon him than before, till a tear or two did steal down the boy's cheek. Then he was sent to his seat, and in a few minutes he was happy with a trap for catching flies which he had contrived in his desk. No doubt they were an unruly set of boys, and I do not suppose the teacher was a hard man, though he led the life of an executioner, and seldom passed a day without inflicting pain that a fiend might shrink from giving. My boy lived in an anguish of fear lest somehow he should come under that rod of his; but he was rather fond of the teacher, and so were all the boys. The teacher took a real interest in their studies, and if he whipped them well, he taught them well; and at most times he was kind and friendly with them. Anyway, he did not blister your hand with a ruler, as some teachers did, or make you stand bent forward from the middle, with your head hanging down, so that the blood all ran into it. Under him my boy made great advances in reading and writing, and he won some distinction in declamation; but the old difficulties with the arithmetic remained. He failed to make anything out of the parts of speech in his grammar; but one afternoon, while he sat in his stocking feet, trying to ease the chilblains which every boy used to have from his snow-soaked boots, before the days of india-rubbers, he found something in the back of his grammar which made him forget all about the pain. This was a part called Prosody, and it told how to make verses; explained the feet, the accents, the stanzas--everything that had puzzled him in his attempts to imitate the poems he had heard his father read aloud. He was amazed; he had never imagined that such a science existed, and yet here it was printed out, with each principle reduced to practice. He conceived of its reasons at the first reading, so that I suppose nature had not dealt so charily with him concerning the rules of prosody as the rules of arithmetic; and he lost no time in applying them in a poem of his own. The afternoon air was heavy with the heat that quivered visibly above the great cast-iron wood stove in the centre of
