He had not long to wait. Almost before he had found time to remove his hat and wipe the perspiration from his brow a shout came echoing up the staircase shaft from the bottom of the ship, announcing the fact that the trap-door was securely closed; and Sir Reginald instantly raised the ship from the ground, sending the engines gently ahead at the same moment, and putting the helm hard over so as to bring the _Flying Fish_ stem-on to the direction from which he expected the hurricane. CHAPTER SIXTEEN. A BATTLE ON LAKE TANGANYIKA. The ship had risen about one hundred feet from the ground, and her engines had just completed a single revolution, when the black pall of murky cloud suddenly burst apart on the south-western horizon, revealing a broad patch of livid coppery-looking sky behind it; and at the same moment a low moaning sound became audible in the breathless air. A dull smoky grey veil of vapour seemed at the same time to overspread the more distant features of the landscape in that quarter, and through it the baronet and his three companions, who had now rejoined him, saw the trees and foliage of the most remote clumps of bush bowing themselves almost to the ground before some mighty invisible force. The moaning sound rapidly increased in power and volume, the cloud of vapour rushed down toward them with appalling speed; the long billowy grass was flattened down to the earth, as if under the pressure of a heavy roller; the successive clumps of bush were seen to yield one after the other to the resistless power of the hurricane, and the air in that direction grew dark with the leaves and branches which were torn from the trees. "Raise the ship higher. Lift her above the power of the hurricane altogether if you have still time to do so," shouted the professor in Sir Reginald's ear, as the roar of the approaching tornado thundered in their ears with almost deafening intensity. "No," shouted back the baronet; "I am going to try the experiment of seeing how she will bear the stroke of the gale. Hold on tight all of you!" And as he spoke he sent the engines ahead at full speed, and drove the ship forward right in the teeth of the hurricane. The next instant, with an appalling burst of sound, the gale was upon them. Contrary to their expectations, there was scarcely any perceptible shock, but the ship's speed was rapidly checked much as is the speed of an express train when the brakes are suddenly and powerfully applied, and in some six seconds, though the engines were still going ahead at their utmost speed, the progress of the _Flying Fish_ over the ground was as effectually checked as though she had been lying at anchor.
