While deeply immersed in his book, Sam heard the sound of approaching footsteps, and pricked up his ears. He was a good judge of such sounds. As they drew near, he quietly took off his cap, put on his helmet, and stepped from his box. The street was very silent; and, perhaps, not one of the hundreds of sleepers there thought of the solitary man who held vigil, and was so alert to do them service, if the hour of their extremity should come. But a cry arose that startled them--"Fire! fire!!" Another moment, and two men dashed round the corner, yelling at the top of their voices. Gasping for breath, they named the locality. Almost before they had done so, two policemen were on the spot, and in another moment the fire-escape was in motion. Instructed by the conductor, the two strangers and the policemen lent their willing aid. Before ten minutes had passed, the tall machine was run up to a burning house, the lower part of which was blazing; while, from the upper windows, frantic cries were heard for help, and sundry figures in dishabille were seen waving their arms. The escape was run up, and one after another the inmates were rescued from their perilous position. While this scene was enacting Frank was pursuing his way to the Regent Street Fire Station; but news of the fire got there before him. He arrived just in time to don his helmet and take his place on the engine. Away they went, and in ten minutes after the arrival of the fire-escape, they dashed up, almost running into an engine which appeared from an opposite direction. The fire was blazing brightly by this time, and the whole neighbourhood was in a state of commotion and excitement. The two engines were got to work with as little delay as possible. A body of police kept the gathering crowd back, and soon volumes of steam began to mingle with the black smoke of the burning building. The superintendent was early on the scene, and he directed Frank and another fireman to try to persuade the people in the adjoining houses to remain quiet, and not throw their furniture over the window; but this, some of them would not consent to do. It was plain that one or two were mad with fear and excitement; and as the ruling passion is strong in death, so it would seem to be by no means weak in the midst of danger from fire; for many of them bent their whole energies to the saving of their goods and chattels--regardless of their lives. One stout old gentleman, in particular, was seen at a third-floor window, heaving out chairs and stools and books, and small tables, and clocks, and even quantities of crockery, with desperate energy, to the great danger of the onlookers, at whose feet the various articles fell, and were dashed to atoms! Frank darted up the stairs that led to this man's apartments, and burst in upon him.
