"Right straight down the centre!" cried Jim, waving to Sam. "You hold on dead straight unless I give you an order. I think we shall just clear her."
But would they? That was the question. The steam launch which had disappeared so mysteriously on the previous night had suddenly darted out from the opposite bank of the river, her decks crowded with men. Moreover, she was fully prepared for a speedy journey, for steam was hissing and whistling from her escape. There was a white wave under her foot, a spreading surf behind her, while the course she followed promised to bring her alongside Jim's vessel before the latter could make her way down the long stretch of water that led to the lagoon. Indeed it looked very much as if the stranger would intercept their passage, and then—what was the prospect?
"Boys," called out Jim after a minute, during which time he had pushed his throttle and ignition levers as far forward as was possible, "see here, boys, there may be a tussle before us. Get to work right now with your rifles. Give it to 'em hot. We may be able to scare 'em."
Pip! Pop! The sharp reports of the Government rifles punctuated the semi-silence which followed, while screams of rage came from the crowded decks of the enemy. Pip! Pop! Tomkins and his friends splashed their bullets in the centre of the throng, and sent more than one of the dusky warriors rolling. Meanwhile, under Jim's guiding hand, the motor launch sped faster towards the lagoon, till her whole frame shivered and vibrated. In such acute cases a second's space of time will change the complexion of matters entirely, will advance the fortunes of one party against those of the other. And here there was an illustration of the fact. Jim's engine raced madly, while the propeller took a firm grip of the water. The vessel bounded forward at a pace which easily outdistanced that of the steam launch. Very soon it became apparent that Jim and his friends would slip past the launch that was steaming from the opposite bank to intercept them.
"Keep at it with those rifles, boys!" he shouted, delighted at the turn matters had taken, and, heedless of the spray of water which gushed in all directions from the rent in the cooling jacket of the motor. "Keep down their fire, and if you catch a sight of those rascals, pepper them properly. Hooray! We'll best 'em yet."
"Run past dem as if they was lame and walking," sang out Tom, bubbling over with excitement. "Den turn and gib dem what fo. Yo tink dat good advice, massa. Yo do as I say; den we knock dem into little pieces. Tom able to find de blackguard dat fired dat shot; den smash um to a jelly."
But seconds bring great changes in the fortunes of parties, as we have already observed, and now, having smiled upon Jim and his comrades, Dame Fortune—a fickle dame at any time—turned her face from them. That rent in the water jacket, the spray which the pump forced past the plug which Ching held in position, proved the undoing of the party. The rhythmical buzz of the engine suddenly ceased. The explosions came haltingly, while the revolutions lessened sensibly, so much so as to reduce the speed of the boat. Then Jim's practised ear told him that the ignition had given out, that the vital spark, without which the motor was useless and now deficient, had been cut off, and thus the motor had been sent adrift. Let us express the matter in proper terms—the flow of water had smothered the magneto, and the current was shorted; no longer did it flow uninterrupted and insulated to the cylinders. It expended its force elsewhere, sent sparks flashing about the magneto, and in the short space of a minute entirely stopped the motor. But the steam launch made no pause in her progress. She pushed on towards the stranded boat swiftly, while a shriek of delight and triumph burst from the horde of natives crowding her decks.
