About a week after our hero's arrival at Dr. Campbell's, the doctor was exhibiting some chemical experiments, with which Henry hoped that his young friend would be entertained; but Forester had scarcely been five minutes in the laboratory, before Mackenzie, who was lounging about the room, sneeringly took notice of a large hole in his shoe. "It is easily mended," said the independent youth; and he immediately left the laboratory, and went to a cobbler's, who lived in a narrow lane, at the back of Dr. Campbell's house. Forester had, from his bed-chamber window, seen this cobbler at work early every morning; he admired his industry, and longed to be acquainted with him. The good-humoured familiarity of Forester's manner pleased the cobbler, who was likewise diverted by the eagerness of _the young gentleman_ to mend his own shoe. After spending some hours at the cobbler's stall, the shoe was actually mended, and Forester thought that his morning's work was worthy of admiration. In a court (or, as such places are called in Edinburgh, a close) near the cobbler's, he saw some boys playing at ball: he joined them; and, whilst they were playing, a dancing-master with his hair powdered, and who seemed afraid of spattering his clean stockings, passed through the court, and interrupted the ball players for a few seconds. The boys, as soon as the man was out of hearing, declared that he passed through _their_ court regularly twice a day, and that he always kicked their marbles out of the ring. Without staying to weigh this evidence scrupulously, Forester received it with avidity, and believed all that had been asserted was true, because the accused was a dancing-master; from his education he had conceived an antipathy to dancing-masters, especially to such as wore silk stockings, and had their heads well powdered. Easily fired at the idea of any injustice, and eager to redress the grievances of _the poor,_ Forester immediately concerted with these boys a scheme to deliver them from what he called the insolence of the dancing-master, and promised that he would compel him to go round by another street.
In his zeal for the liberty of his new companions, our hero did not consider that he was infringing upon the liberties of a man who had never done him any injury, and over whom he had no right to exercise any control.
