"We"ve got full tanks," Scotty observed. "Might as well get started."
"I think this also," Chahda agreed. "We not miss any islands. Besides, these far out of way, not on ship lanes. Could be good place for pirates."
"My thoughts exactly," Zircon stated. "Who has the wheel?...
Chahda?... All right. Head southeast, and I"ll plot a course."
"Why not use both engines?" Rick suggested. "Then we can get there before dark. If nothing turns up, we can travel all night from there to Sibutu. It"s all open water."
"If we use both engines, someone had better keep watch from on top of the pilothouse," Scotty added. "Then, if we see vintas, we can throttle down. That way, we won"t have to give up our disguise of being a partial cripple."
"Good idea," Zircon approved. "Suppose you start, Scotty? Rick can relieve you later."
Rick grinned. "That"s what you get for having ideas. Tell you what, I"ll toss you. Heads I take the first watch topside, tails I"ll start making lunch."
"Sold." Scotty produced a centavo and they flipped. Rick won and climbed to the top of the pilothouse while Scotty went below to prepare sandwiches.
Rick sat in a canvas chair Zircon handed up to him and watched the sea, now and then sweeping the horizon with Shannon"s long gla.s.s. The _Swift Arrow_ cut the water cleanly, with both engines roaring at three-quarters throttle.
They were cruising the Celebes Sea now, the Sulu Archipelago rapidly falling astern. It was a calm, clear day without even a single whitecap to mar the blue perfection of the sea. Now and then a school of flying fish broke water from under the MTB"s bow, and twice Rick spotted sharks, one of them a hammerhead. There were no vintas in sight.
Zircon handed up sandwiches and coffee, then relieved Chahda at the wheel. The Hindu boy"s shoulder was healing nicely, but it was still a little stiff and he was careful not to move his arm more than necessary for fear of breaking open the wound.
The afternoon wore on without sign of a sail. Scotty relieved Rick, who relaxed on the afterdeck. The boy glanced at his watch. They should be picking up the islands soon.
Suddenly Scotty sang out, "Sail ho."
"How many?" Rick called.
"Just one. On the horizon, off the port bow."
Rick relieved Chahda at the helm, and the Hindu boy hurried below, saying that he wanted a cold drink before the fight started. Rick watched for the vinta sail, but before the craft was visible from his lower vantage point, Scotty called out again. "Land! Behind the vinta.
Looks like a coral atoll. I can see the tips of palms."
Zircon checked the chart. "It should be the most westerly of the three islands," the physicist reported. "Scotty, any more vintas?"
"Just the one."
"Head for the island," Zircon instructed Rick. "We"ll want a close look."
Chahda emerged from the galley with cold c.o.kes for all hands, and they drank while waiting for the boat to get within examination distance of the island. It was clearly visible within a short time. As Scotty had said, it was a coral atoll, the highest point not more than ten feet above sea level.
They pa.s.sed the vinta at a distance of a hundred yards. There were only three men aboard, and they were fishing. Then Rick cut closer to the island while Scotty kept a sharp lookout for shoal waters and coral heads.
Details were clearly visible now. There were a dozen huts on the island, and only a handful of people were visible. Zircon took the long gla.s.s from Scotty and inspected carefully, "Apparently it"s a small fishing community. I see nets, and another three vintas pulled up on sh.o.r.e.
There seems to be ... Wait!"
Rick watched as the scientist swung the long gla.s.s into the air, followed something for a moment, then lowered it, his face grim.
"I caught a glimpse of a man releasing something into the air, and managed to pick it up with the gla.s.s. It was a pigeon. And you know what that means!"
The boys did. "Which way did it go?" Rick asked.
"Due east."
Rick swung the MTB onto an easterly course without another word. He knew from the chart that the biggest island of the three in the Datu Amman Group lay that way. The third island was about ten miles to the north.
Release of the carrier pigeon could mean only that the island they were now pa.s.sing was a lookout position, from which the people on the biggest island had now been notified of their arrival. And that meant ... what?
Rick had a good idea, which inspection should soon prove!
"Land ho!" Scotty called down. "It"s a peak of some sort."
Rick saw it a few moments later, a golden glitter on the ocean as the fast-setting sun struck land.
The four watched as the land ma.s.s slowly took shape. "It"s a mountain, all right," Zircon said, excitement in his booming voice. "Looks like a volcanic cone. Can you see it clearly, Scotty?"
"It"s a cone, and not much land under it, either. Hey! Vintas ahead!
Must be a hundred of them!"
Rick felt excitement surge through him. That was too many vintas for a simple fishing community on an island of small size!
"They"re forming a line between us and the island!" Scotty called down a moment later.
Rick could make out the tips of sails, and as the _Swift Arrow_ forged ahead, the entire fleet slowly came into view. Scotty was right. The vintas were in a line--like a planned defense!
The island was almost entirely visible, now. A volcanic cone, perhaps five hundred feet high, formed most of the island. From the base of the cone, flat land spread out toward the oncoming MTB, ending in a white beach.
"Get within gunshot of the vintas," Zircon directed grimly. "Let"s see if they"re really hostile. If they are, we"ll know we"ve found something. And forget the crippled engine disguise. It"s served its purpose."
Rick figured his course carefully. He would take the MTB on a gradually sweeping curve that would place them within gunshot, but in a position to beat a fast retreat. In a few minutes, now, they would be in position. He kept his fingers crossed. Things looked promising. If this were only the end of the search.
He throttled back a little, in order to keep a good amount of speed in reserve, and kept the MTB on the course he had planned, sweeping toward one end of the vinta line. He saw the outrigger craft back their sails as they turned to intercept him. Then, as the long curve brought him within rifle range he put the helm hard over, running broadside to the line of bright sails.
Scotty called, "Watch it! Heads down!" The boy was flat on the top of the pilothouse now, his own rifle within reach.
As an echo to his warning Chahda yelled, "They shoot!"
Rick couldn"t hear the shots above the engine roar, but he took Chahda"s word for it. He put the helm over again, turning the stern toward the line of boats.
Scotty jumped to the deck. "They took several shots at us, but none hit.
I saw the muzzle flashes."
Zircon nodded. "I saw muzzle flashes, too. Lads, it looks as though we"ve really found something, including a mountain. Now, I suggest we reconnoiter thoroughly."
"What"s your plan?" Rick asked.
"Circle the island completely, at close range. Swing wide, to approach from the north, then go around the island clockwise, staying as close to sh.o.r.e as safety allows. We can outrun the vintas without trouble. If necessary, we can even cut inside the line for a close look." The big physicist was almost trembling with excitement.
Rick wasted no time in swinging north, away from the vintas. Scotty went back to the top of the pilothouse to watch for shoal waters. Once he was far beyond the line of vintas, Rick cut back again, pointing the bow of the MTB at the northern sh.o.r.e of the island. He took out his handkerchief to wipe palms that were suddenly damp with nervous perspiration. This had to be the place!
He could see now that the volcanic peak occupied the entire eastern part of the island. It dropped steeply into the ocean on both the eastern and northern sh.o.r.es. The inhabitable land area was a broad shelf that sloped from the base of the volcano to the western sh.o.r.e.
