When he was at length sent to Mr. M‘Adam’s commercial school, the change caused him many trials and much suffering. He found himself completely out of place in the midst of the boisterous juvenile republic. Against the tyranny of the elders he was helpless; their wild play was most distasteful to him; he could not join in their sports, nor roam with them along the beach, nor shy stones into the water, nor take part in their hazardous exploits in the harbour. Accordingly they showered upon him contemptuous epithets; and the school being composed of both sexes, the girls joined in the laugh. He shone as little in the class as in the playground. He did not possess that parrot power of learning and confidence in self necessary to achieve distinction at school; and he was even considered dull and backward for his age.[55] His want of progress may, however, in some measure be accounted for by his almost continual ailments, which sometimes kept him for weeks together at home. It was not until he reached the age of about thirteen or fourteen, when he was put into the mathematical class, that his powers appeared to develop themselves, and from that time he made rapid progress. [55] The truth in regard to young Watt’s first years in the public school is, that, owing doubtless to infirm health, to the suffering and depression which affected his whole powers, he was prevented for a considerable time displaying even a very ordinary and moderate aptitude for the common routine of school lessons; and during those years he was regarded by his schoolmasters as slow and inapt. Although to some minds facts of such a nature may be conceived to mar the romance of a great man’s history, yet, seeing they rest on authenticity which cannot be impugned, there appears no reasonable ground on which it may be thought that they ought to be passed over as if they had not existed, or were altogether unfounded.--Williamson’s ‘Memorials of Watt,’ p. 130.
