Watt now reached his seventeenth year. His father's affairs were greatly embarrassed. It was clearly seen that the two brothers, John and James, had to rely for their support upon their own unaided efforts. John, the elder, some time before this had taken to the sea and been shipwrecked, leaving only James at home. Of course, there was no question as to the career he would adopt. His fortune "lay at his fingers' ends," and accordingly he resolved at once to qualify himself for the trade of a mathematical instrument maker, the career which led him directly in the pathway of mathematics and mechanical science, and enabled him to gratify his unquenchable thirst for knowledge thereof. Naturally Glasgow was decided upon as the proper place in which to begin, and Watt took up his abode there with his maternal relatives, the Muirheads, carrying his tools with him. No mathematical instrument maker was to be found in Glasgow, but Watt entered the service of a kind of jack-of-all-trades, who called himself an "optician" and sold and mended spectacles, repaired fiddles, tuned spinets, made fishing-rods and tackle, etc. Watt, as a devoted brother of the angle, was an adept at dressing trout and salmon flies, and handy at so many things that he proved most useful to his employer, but there was nothing to be learned by the ambitious youth. His most intimate schoolfellow was Andrew Anderson, whose elder brother, John Anderson, was the well-known Professor of natural philosophy, the first to open classes for the instruction of working-men in its principles. He bequeathed his property to found an institution for this purpose, which is now a college of the university. The Professor came to know young Watt through his brother, and Watt became a frequent visitor at his house. He was given unrestricted access to the Professor's valuable library, in which he spent many of his evenings. One of the chief advantages of the public school is the enduring friendships boys form there, first in importance through their beneficial influence upon character, and, second, as aids to success in after life. The writer has been impressed by this feature, for great is the number of instances he has known where the prized working-boy or man in position has been able, as additional force was required, to say the needed word of recommendation, which gave a start or a lift upward to a dearly-cherished schoolfellow. It seems a grave mistake for parents not to educate their sons in the region of home, or in later years in colleges and universities of their own land, so that early friendships may not be broken, but grow closer with the years. Watt at all events was fortunate in this respect. His schoolmate, Andrew Anderson, brought into his life the noted Professor, with all his knowledge, kindness and influence, and opened to him the kind of library he most needed.
