And _make for it_ with perfect safety. In time past human lives, and noble ships, and costly merchandise were lost on the Bell Rock every year. Now, disaster to shipping there is not even dreamed of; and one of the most notable proofs of the value of the lighthouse, (and, indirectly, of all other lighthouses), lies in the fact, that not a single wreck has occurred on the Bell Rock since that auspicious evening in 1811 when the sturdy pillar opened its eyes for the first time, and threw its bright beams far and wide over the North Sea. CHAPTER THREE. NIGHTS WITH THE FIRE BRIGADE. There are few lives, we should think, more trying or more full of curious adventure and thrilling incident than that of a London fireman. He must always be on the alert. No hour of the day or night can he ever count on as being his own, unless on those occasions when he obtains leave of absence, which I suppose are not frequent. If he does not absolutely sleep in his clothes, he sleeps beside them--arranged in such a way that he can jump into them at a moment's notice. When the summons comes there must be no preliminary yawning; no soft transition from the land of dreams to the world of reality. He jumps into his boots which stand invitingly ready, pulls on his trousers, buttons his braces while descending to the street, and must be brass-helmeted on the engine and away like a fiery dragon-gone-mad within three minutes of "the call," or thereabouts, if he is to escape a fine. Moreover, the London fireman must be prepared to face death at any moment. When the call comes he never knows whether he is turning out to something not much more serious than "a chimney," or to one of those devastating conflagrations on the river-side in which many thousand pounds worth of property are swept away, and his life may go along with them. Far more frequently than the soldier or sailor is he liable to be ordered on a duty which shall turn out to be a forlorn hope, and not less pluckily does he obey. There is no respite for him. The field which the London Brigade covers is so vast that the liability to be sent into action is continuous-- chiefly, of course, at night. At one moment he may be calmly polishing up the "brasses" of his engine, or skylarking with his comrades, or sedately reading a book, or snoozing in bed, and the next he may be battling fiercely with the flames. Unlike the lifeboat heroes, who may sleep when the world of waters is calm, he must be ever on the watch; for his enemy is a lurking foe--like the Red Indian who pounces on you when you least expect him, and does not utter his warwhoop until he deems his victory secure. The little spark smoulders while the fireman on guard, booted and belted, keeps watch at his station. It creeps while he waits, and not until its energies have gained considerable force does it burst forth with a grand roar and bid him fierce defiance.
