At the period of which we write, the then Chief of the London Fire Brigade, Mr Braidwood, had introduced a system of gymnastic training among the firemen, which he had found from experience to be a most useful exercise to fit the men for the arduous work they had to perform. Before going to London to take command of and reorganise the brigade which then went by the name of the London Fire-Engine Establishment, and was in a very unsatisfactory condition, Mr Braidwood had, for a long period, been chief of the Edinburgh Fire Brigade, which he had brought to a state of great efficiency. Taking the requirements and conditions of the service in Edinburgh into consideration, he had come to the conclusion that the best men for the work in that city were masons, house-carpenters, slaters, and suchlike; but these men, when at their ordinary employments, being accustomed to bring only certain muscles into full play, were found to have a degree of stiffness in their general movements which prevented them from performing their duty as firemen with that ease and celerity which are so desirable. To obviate this evil he instituted the gymnastic exercises, which, by bringing all the muscles of the body into action, and by increasing the development of the frame generally, rendered the men lithe and supple, and in every way more fitted for the performance of duties in which their lives frequently depended on their promptitude and vigour. In addition to these advantages, it was found that those exercises gave the men confidence when placed in certain situations of danger. "For example," writes Mr Braidwood, "a fireman untrained in gymnastics, on the third or fourth floor of a burning house, with the branch in his hands, who is uncertain as to his means of escape, in the event of his return by the stair being cut off, will be too much concerned about his own safety to render much service, and will certainly not be half so efficient as the experienced gymnast, who, with a hatchet and eighty feet of rope at his waist, and a window near him, feels himself in comparative security, knowing that he has the means and the power of lowering himself easily and safely into the street"--a knowledge which not only gives him confidence, but enables him to give his undistracted attention to the exigencies of the fire. It was to attend this gymnastic class that Frank now turned aside, and proposed to bid Willie goodbye; but Willie begged to be taken into the room. Frank complied, and the boy soon found himself in an apartment fitted up with all the appliances of a gymnasium, where a number of powerful young men were leaping, vaulting, climbing, and in other ways improving their physical powers. Frank joined them, and for a long time Willie stood in rapt and envious contemplation of the busy scene.
