The heat and the arduous exertion made Johnny Kent grunt, but he had been a mighty man with a shovel in his time, and he would show these scoundrels how to feed a furnace. He observed that armed guards were stationed in this compartment, and concluded that some of the steamer’s regular crew had been set to work under compulsion.
Thus far he had made no blunders. There had been no flaw in his plans. His greatest fear was that Vonderholtz might come below and recognize him. But the conflagration conducted by Captain O’Shea was likely to keep the leader on deck.
Painstakingly Johnny Kent sought to recall every scrap of information he had read in technical journals concerning the under-water specifications of the Alsatian. His memory was tenacious and he believed that he could trust it now.
He had entered the fire-room in the middle of a watch, and therefore had not long to serve as a stoker before the men were relieved and another gang took their places. When the next watch came trooping in, there was much passing to and fro, and as one of the crowd Johnny Kent felt much safer against discovery. He knew where to find dark corners and tortuous passageways in this complex, noisy part of the ship, far below the water-line.
When the firemen of his watch began to climb the ladders to their living quarters, he was not among them. Two hours later, a bulky gray-headed person in blue overalls might have been seen crawling on hands and knees or wriggling on his stomach in the bilge of the Alsatian’s hull, beneath the floor.
From the state-room wall he had unscrewed the small candle lamp provided for use when the electric-lighting system was turned off. With this feeble light he was searching for the sea-cocks, those massive valves set into the bottom of a steamer’s hull for the purpose of letting in the ocean and flooding her in the emergency of fire in the cargo holds and coal-bunkers. A steamer is sometimes saved from total destruction by beaching her in shoal water and opening the sea-cocks.
To open these valves in the bottom of the Alsatian was to admit a rush of water which would soon rise to the furnaces and engine-room in greater volume than the steam-pumps could hold in check. It was not Johnny Kent’s mad intention to sink the liner in mid-ocean, although this was a possible consequence.
After prodigious exertion, he found what he sought and bent his burly strength to releasing the gate-valves constructed to withstand the pressure of the sea. He heard the water pour in with sobbing gush and murmur and splash against the steel plates and beams. With a healthy prejudice against being drowned in a cataract of his own devising, Johnny Kent scrambled in retreat and regained the engine-room compartment, bruised and exhausted.
Thus far he had succeeded because of the sheer audacity of the enterprise. It was a seemingly impossible thing to do, but the process of reasoning which inspired it was particularly sane and cool-headed. He had been unchallenged because it never entered the minds of his foes that any one would dare such a stratagem. They had gained the upper hand by means of force. In a game of wits they were out-manœuvred. Johnny Kent showed the superior intelligence.
“It looks as if my job as Daniel in the lions’ den was about done,” he said to himself.
