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 s.p.a.ce 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.

CHAPTER XI

Barely Escaped

Tall and lean, the natives aboard the steam launch were plainly visible for a moment, so much so that Jim, having regarded his useless motor desperately for some few seconds, was compelled to give his attention to the enemy. Tall and thin, each one of the natives was almost naked.

Their bodies were painted with broad stripes of white, which at a distance made one think of skeletons; while vermilion was daubed on the cheeks, giving each individual the same air of ferocity. For the rest, these men wore their long hair plaited into queues, and bore about their persons a simple belt in which a long knife was suspended.

But when events are moving fast, and disaster stares one in the face, details and trifles escape attention. Jim and his comrades had their safety to think of, so that it is not wonderful that they failed to observe too closely the appearance of their dusky enemies. But however urgent the position, none could fail to see the short spears, with long narrow blades attached to them, which each dusky warrior carried. Half a dozen at least were gripped in each left hand, while the right held a single one in readiness to discharge it. As for the gun, the cheap gas barrels with which these wretched natives had been supplied, they were without exception muzzle loaders; and now that events were moving so fast and so furiously there was hardly time to load. A few of the men handled their ramrods, but the rest had discarded their weapons and stood prancing upon the deck of the launch, causing her to heave and roll dangerously, and prepared to throw their spears the instant they came within range of Jim and his party. It was not until that moment that our hero realized that if their fortunes were desperate they were at least lucky in one particular.

"Gee, ain't I glad!" he exclaimed. "From what Phineas told me I quite expected them to be armed with bows and arrows--the latter poisonous.

Tomkins, you and your men had best concentrate your force aft of the launch, where the engine is. I caught a glimpse of those rascals there; and though I don't suppose that the death of one or both would cause the gang to sheer off, yet it might do so, and in any case if we could put them out of action there would be no white man to lead the natives."

"Right, sir, right," came from Tomkins instantly, while he and his two comrades promptly moved to the back of the cab, from which point they could best command that portion of the launch upon which they were instructed to concentrate their fire.

"You, Tom and Sam, fire on the natives," shouted Jim. "I'm going to help you. Ching, get hold of some of that clean cotton waste and wipe up all round this magneto. Dry every part you can, and don't forget those plugs on top of the cylinders."

He had already pointed out the ignition plugs to the Chinaman, for they, like the rest of the engine, had been heavily sprayed with water.

Then he seized a rifle, jerked the magazine open as the Major had instructed him when they first set out on the expedition, and levelled his sights upon the advancing natives.

By now the latter were dangerously near, and already clouds of spears were flying. It looked as if within a few seconds the steam launch would be right alongside, and the black demons aboard her hurling themselves upon the decks of the motor. But suddenly there came a high-pitched shriek amidst the howls of the enemy, and to the relief of all in Jim's party the course of the other vessel was abruptly altered. She shot away obliquely to the left, while one of the white men who had been manning the wheel was seen to tumble backwards.

"A grand shot," shouted Jim. "Now is our time to get this motor running.

Out of the way, Ching, and let me get to her. We'll see how she'll run without water in her jackets."

The idea had suddenly flashed into his brain, and he proceeded promptly to put it into execution. But, first of all, now that he had a short breathing s.p.a.ce, it was necessary to supervise the work that Ching had been doing.

"It'll take 'em a good five minutes to round up and get back here within range," he told himself, glancing across at the enemy. "That splendid shot and the fall of their steersman have caused no end of confusion, and now is the time to best them."

Laying his rifle down hurriedly, he bent over the magneto and seized a handful of dry cotton waste.

"Me mop up all de water," grinned Ching, looking the coolest person aboard the launch. Indeed, there seemed to be little doubt that he was actually the least concerned of all the party, for his inexpressive features had not changed in the slightest. There was not so much as a tinge of red in his sallow cheeks, sure indication of some excitement.

His almond eyes--all aslant, as is common to this Eastern race--regarded Jim, the useless motor, and the howling band of natives steaming across the water with the same tranquillity. "Wipey all de water up, Ma.s.s Jim,"

he repeated. "Now, s'pose you start him. He go velly nicely p'laps. Den run away from dem rascals, and Ching put de kettle on, hab someting to eat, 'cos Ching hungry, velly."

"Get out of this!" cried Jim irritably. "Breakfast, man! Why, if we don't get out of this in the next few minutes there won't be one of us left to take a bite!"

He pushed the Chinaman to one side, and rapidly ran over his ignition system. Ching had done his work with that painstaking thoroughness for which the Chinaman is noted, and though hollows and crevices in and about the motor still held pools of water, the vital parts were dry.

"Then I'll try it," he said. "Those beggars have managed to turn rather quicker than I had imagined; but if I can only get her going within a minute we ought to be able to escape them. Ah! here come their bullets again, boys; get in at them with your rifles."

All the while he had been troubled with the want of one small article.

To keep the water out of his motor he must plug the opening which led from the vessel's side direct to the pump. For the rest, it was an easy matter, there being a tap which would drain all the jackets within the s.p.a.ce of but a few seconds. But that alone was insufficient; with the water port still open, the pump would drive a column of fluid through the jackets, and the ignition would be again drenched.

"A cork! a cork!" he cried. "Something with which to fill this port."

He leant over the side of the vessel and pointed out the opening to Ching. And the wily, cunning Chinee immediately came to his a.s.sistance.

"A cork, sah; I's got the velly thing. You wantee someting to push in dere. Ching hab plenty fine cork."

He moved with exasperating slowness across the engine well, and rummaged in a locker in which his cooking utensils were stored. There came the characteristic sound of a bung being extracted from a bottle, and then Ching came back again, still slowly, still unconcernedly, still with that unruffled countenance.

"He, he, he! him come out of the vinegar bottle," he giggled. "Him one velly fine cork, Ma.s.s Jim. But yo gib him back when yo finished? Eh?

Velly fine cork dat."

Jim s.n.a.t.c.hed it from his hand without ceremony, in fact with a brusqueness altogether foreign to him. Then he leaned over the side of the launch and gave a shout of triumph when he discovered that Ching had supplied him with an article which fitted nicely. He rammed it home forcibly, driving his fist through the water against the cork. Then he bounded to the engine, jerked the starting handle into position, and sent the motor whirling. Bizz! She was off. The engine went away with an encouraging roar, while but a few ounces of water escaped from the rent in her jacket.

"Wipe it up," he commanded Ching. "And guess you'd better keep clear of the magneto and plugs and suchlike. If you touched them you'd get a shock that would knock you endways. Gee! Ain't she buzzing! Hooray!

we'll best them."

Sam was already at the steering wheel of the launch, watching his master out of the corner of his big eyes, and paying some attention to the enemy. Indeed he would not have been human had he failed to cast more than one anxious look in their direction. Sam was not the same stolid, supernaturally unemotional individual as the Chinaman. He had nerves; excitement told on the little fellow.

"Dey almighty near, sah," he sang out. "Dat motor goin'? den, fo'

goodness sake, put de gear in, push on, get away from dem demon."

"Dodge 'em; swing her about. Put out their aim," Jim called to him, and at once pushed his gear lever home. Then, like the practical young man he was, he reached over to his lubricators and sent them dripping at a pace which, while they would not flood the engine and overlubricate her, would still supply a more abundant amount than usual, and so in a measure serve to counteract the want of water cooling.

"She's bound to run hotter," Jim told himself, "and as a permanent arrangement the thing wouldn't do; but for the time being it's got to.

Round with her, Sam."

The launch meanwhile had floated quietly on the surface of the river, and, owing to the fact that her propeller was stationary, being thrown out of gear by the failure of the engine, she had lost steerage way, and had drifted completely round. She was heading upstream when Jim set her propeller thrashing the water again, and for a while she raced away from the other vessel, the manoeuvre drawing shrill yells of rage from the natives. But Sam had her in hand. The fine little fellow had not been with Jim and his father all this time without learning how to steer a launch, and at once, with a glance over his shoulder, he sent his wheel round, causing the boat to flop over and heel till her rail was almost under the surface. Round she spun on her keel, and within the half-minute was heading direct for the enemy. A growl broke from Tomkins as he laid his cheek once more down on the b.u.t.t of his rifle.

"This time guess we'll make hay with 'em," he shouted. "Don't you be in too much of a hurry, sir. You can make rings all round 'em and still keep out of range. Dare say their bullets'll reach right enough, but they won't strike hard enough to hurt more'n a fly. It's the spears I'm frightened of."

And everyone else, too; for the natives aboard the oncoming launch had again discarded their firearms, and were now standing, spear in hand ready poised, waiting for the moment when they might cast them. Sam gave every dusky warrior a start when he headed the launch direct for them.

It looked as if he were bent on a collision; but a minute later, when effective range for the spear throwers had almost been reached, he put his wheel over again, and shot the launch away at a right angle. Then a figure aboard the enemy was seen to rise erect beside her steering gear, and within the s.p.a.ce of a few seconds she paid off in the same direction as Jim's craft had taken--on a course, in fact, which would bring the two boats alongside very shortly. Either that or they must run hard into the bank.

"Right round with her again; dodge them!" shouted Jim, his heart in his mouth. "Then take her up stream a little. We have the legs of them, and if only we can shake them clear for a while we shall get past them."

That was the difficulty. The enemy remained all the while between them and the lagoon, and in that direction safety lay. Even a swift boat such as the motor launch had proved herself to be could not slip by easily, unless she risked running so close into the other as to place her crew in danger of those terrible spears; but Sam seemed fully to have realized the difficulty, and at Jim's command he brought the boat heeling round again. Hardly three lengths separated the combatants when he swung the wheel again, and, driven by her fast-rotating propeller, the launch shot obliquely up the stream, leaving the other heading helplessly for the bank. Tom roared with delight, brandishing his rifle overhead, while Ching giggled and simpered as if he looked upon the thing as a glorious joke. But Jim's face was set and stern. He had been so close when the vessel turned that he had been able to look into the eyes of the natives; and the ferocity of their appearance, their terrible shrieks and howls, and the cloud of spears which they had discharged brought realistically to him the depth of their danger.

Within a foot of his hand a spear stood quivering, the blade sunk deeply in the woodwork. It needed but a glance to tell him that the weapon was capable of dealing death to anyone. However, they were out of range now, and the time had come to practise a further manoeuvre. Jim waved his hand in Sam's direction.

"Over," he shouted. "Let her rip for the lagoon."

Meanwhile the course of the other launch had been hurriedly arrested; for the ruffian aboard her was a clever skipper, and handled the craft with decision. The waters churned into white foam beneath her rudder, and before Jim and his friend had completed their slanting run upstream the rascal had his boat running rapidly astern in an effort to intercept them.

"Gee, he'll do it, too!" shouted Tomkins. "Say, sir, we'll have to charge them. But that would mean the end of everything for them and for us."

Jim shook his head emphatically. "You're asking for a funeral," he said bluntly. "We've got to dodge 'em, even if we play at the game for the rest of the morning. Steady there, Sam; do anything rather than let them get within close range of us. Boys, if only you could pick off that rascal who commands them we would soon make an end of the others."

But the man aboard the other boat proved to be as crafty as he was capable. True, they had obtained a clear view of him on one occasion, at least, when he had dashed for the steering gear of his vessel. But now a gaudily painted native occupied that responsible position, while the Spaniard himself lay out of sight in the engine well, but near enough to prompt him. The rim of his hat could be seen on occasion as he glanced across at Jim and his party. As for our hero, seeing that the course was blocked, and that for the moment their escape was cut off, he coolly threw his lever out of gear and slowed down his engine. Then he reversed his propellor for a while until the launch had come to a standstill.

"Two can play at this sort of game," he told himself. "We'll wait and see what that fellow proposes to do; but listen here, Tomkins, and you other fellows. Next time we attempt a rush we have to make a big impression on these natives. We'll get them end on, if we can, and then try them with volleys. We want to make every shot tell, and that hasn't been the case up to the present. A moving target isn't too easy to hit from a launch when she's heaving and rolling."

"Lummy! Look dere! By de poker, dere more of de sc.u.m. Yo see dem black sons ob guns coming right away dere? Dey likely to be very troublesome."
