Hist! A succession of faint sounds like those of a man stealthily swimming caused Ellerton to sit bolt upright, grasp his rifle, and peer intently through the darkness.
There was no mistake about it. It was some object heading directly for the yawl, its track being marked by a faint blur of phosph.o.r.escence.
Visions of bloodthirsty savages, swimming, knife in mouth, to surprise the crew of the little craft, filled Ellerton with alarm. He raised his rifle, released the safety catch, and took aim at the mysterious intruder.
"Andy," he whispered, but his friend was too deep in slumber to be awakened by a whisper.
"I"ll wait till he"s close alongside," muttered Ellerton, fingering the trigger.
At that moment there was a perceptible jar alongside the boat, followed by a prolonged grating sound, as if a piece of sandpaper were slowly drawn over a rough surface. Then, with a swirl and a succession of phosph.o.r.escent splashes, the object vanished.
The sound had roused Andy.
"What"s up?" he exclaimed, springing into the c.o.c.kpit.
Both lads looked over the side. Deep beneath the surface they saw a huge luminous shape slowly gliding away.
"My word!" whispered Andy. "Can"t you see what it is? It"s a shark."
"I thought it was some natives swimming off to us."
"Never fear. They"ll never attempt such a thing with a sentry like that brute," replied Andy as he re-entered the cabin.
Slowly the weary hours pa.s.sed, till the sun rose in a sky of misty grey, and the inhabitants of McKay"s Island, both black and white, bestirred themselves into activity.
"Not much wind, boss," was Chinese Pork"s salutation as Mr. McKay and his companions arrived at the beach, whither Andy had rowed in the "tender.
"There"ll be some before long," replied Mr. McKay. "It usually springs up about an hour after sunrise."
"It"ll mean a long pull if it doesn"t," rejoined Blight. "Shall I lend you four or five hands to work the sweeps?"
"I"ll not trouble you, thanks. It"s your men who will find it hard work, I fancy."
"Say, why? You just see them use those paddles. They"ll keep it up for hours at a stretch. Your craft"ll be the tail end of this "ere procession, I guess."
"We shall see," replied Mr. McKay quietly, for he had no desire to enlighten the ex-pearler upon the subject of the motor.
"Say, boss?"
"Well?"
"That"s a rum packet," said Blight, indicating with a jerk of his thumb the boat the lads had made from the wreck of the gig. "I bet you never bought her at Hilo?"
Mr. McKay did not reply. He quite realised that the ex-pearler was trying to pump him, while, on the other hand, he was equally determined to conceal the fact that he and his companions were on the island through shipwreck.
Although Mr. McKay hated deception, he wished to convey the impression that they settled here by choice, yet Blight"s question showed that he kept his eyes open.
"Are you ready to start?" demanded Mr. McKay. "There"s a wind springing up from the south-east"ard."
"As soon as you like. But can you lend me a revolver, cap"n? I"ve got a bloomin" Martini, but I"ve run out o" cartridges months and months ago."
"Here you are, and here are fifty cartridges. I"ll make you a present of the pistol," replied Mr. McKay, though he realised that he was playing into the man"s hands.
Then, without waiting to receive the ex-pearler"s thanks, he stepped into the boat and was rowed off to the yawl.
"Good morning, Ellerton," he exclaimed. "All quiet, I suppose? Well, let"s get the canvas on her."
Already the natives were hauling their canoe down the beach, and by the time the yawl had set her sails the splash of a score of paddles showed that they had lost no time in embarking.
"Up with your helm, Andy; check the jib sheets."
Then, as the little craft drew clear of the land, the freshening breeze caused her to heel and glide through the ruffled water of the lagoon.
By the time they had gained the pa.s.sage through the reef the yawl was ahead of the canoe.
"Glorious!" e.j.a.c.u.l.a.t.ed Andy. "See, they"re setting their sail. It will be a good race, after all."
Half a dozen bronzed natives were setting the raking mast and bending the yard with its enormous sail of cocoa fibre. Then, as the sail rose swiftly in the air, the breeze filled the mat-like canvas. The crew took in their paddles and watched the yawl with curious eyes.
"We are gaining on her, I think," remarked Andy.
"Yes; we must shorten sail," replied Mr. McKay. "But I want particularly to note the respective speeds of the two craft. I should think that, under sail and aided by her paddles, that canoe could overhaul us under sail alone. Yes," he continued, after a few moments"
careful observation. "I think I"ve seen enough in case of future developments, so we"ll strike the topsail."
Under reduced canvas the yawl kept the canoe at a regular distance from her, neither gaining nor allowing the latter to overhaul her. Quexo, fearing an attack of sea-sickness, had retired to the seclusion of a berth in the fo"c"sle, while Ellerton and Terence, who had kept the last portion of the previous night"s watch, followed his example, though from other motives.
Andy was steering. His father, who had given him the course, was below preparing a meal.
The wind held steadily all the forenoon, and by eleven o"clock the summit of McKay"s Island had dipped beneath the horizon. It was not without feelings of regret that Andy saw it disappear. He, too, realised that they were embarked upon a hazardous mission, and that possibly great sacrifice would have to be made ere they returned to their island home.
At midday the wind died away to a flat calm, the yawl rolling sluggishly in the oily swell, with her boom swaying violently from side to side, and threatening dire disaster to the heads of any of the crew that incautiously came within its reach.
The canoe, similarly situated, did not hesitate to lower the sail, and paddle close alongside.
"This is a bit rotten, cap"n," shouted Blight. "Shall I give you a tow?"
"No thanks, don"t trouble about us," replied Mr. McKay. "You can paddle on ahead, and we"ll follow when the breeze springs up. If we can"t fetch Ni Atong before dark you might get those fellows to light a fire on the beach, so that we can come up to the anchorage."
"Righto, boss! Ta-ta!"
There was a peculiar glint in the man"s eye. He fancied that the superior speed of the canoe under paddles was an a.s.set in his favour for the events he had already planned.
The chief gave the word, the blades dipped, and, gathering way, the canoe soon gained a rapid pace. The long-drawn song of the paddlers gradually died away as the distance increased, and an hour later the canoe was lost to sight.
"Now, Andy, we"ll start the motor, and creep up within a couple of miles of Ni Atong. They will think we have picked up a breeze."
"Why don"t you want to let that chap Blight know we"ve a motor?"
