“Mr. Pearson’s visit led to intimacy between the families, especially as regards the children; and as his eldest daughter had attained the age of five, while I was no more advanced than six, the two were naturally thrown much together, and, in fact, took the first step towards that intimacy and affection which some twenty-five years later were cemented by marriage. One whimsical little passage in these earliest days I must record. Under the high road, in the part nearest to my father’s house, ran what is in the midland counties called a culver (that is a long low arch), placed there for the passage of the rivulet, which turned my little water-wheel. Into this culver my brother and I occasionally crept by way of adventure, and at times to hear the noise of a wagon as it rumbled slowly overhead. Into this ‘cool grot and mossy cell’ I once led my new companion, both of us necessarily bending almost double; and I cannot but look back upon the proceeding as probably our earliest instance of close association and mutual confidence. Many years later we revisited the spot together, but found the passage completely silted up, so as to be inaccessible to future wooers, however diminutive.” At the age of three or four, Rowland was nearly carried off by the scarlet fever. So ill he was that for a short while his father and mother thought that he had ceased to breathe. The attack left him weak for some years. “I have never overcome,” he wrote in his eighteenth year, “and most probably never shall quite overcome, the effects of that illness. Ever since I can remember I have suffered much from sickness.” He had to pass many hours of every day lying on his back. He used to beguile the time by counting. He assisted himself, as he said, by a kind of topical memory. “My practice was to count a certain number, generally a hundred, with my eye fixed on one definite place, as a panel of the door, or a pane in the window, and afterwards, by counting-up the points, to ascertain the total.” He here first showed that love of calculation which so highly distinguished him in after life. His health remained so feeble that he had passed his seventh birthday before he was taught his letters. Backward though he was in book-learning, he was really a forward child. At the age of five he had made himself a small water-wheel, rude enough no doubt. Yet it worked with briskness in a little stream near his father’s house. A water-wheel had always a great charm for him. He had been taken to see one before he was three years old, and he used to cry to be taken to see it again. When he was an old man he would go miles out of his way to see one at work. The year after he made his wheel, when he was now six, he and his brother Edwin, a boy of eight, built themselves a small model-forge of brick and mortar. The wheel was about two feet and a-half across, and was pretty fairly shaped.
