The raft was ready to float off at last. The boys gave the girls a hug and said good-bye.
"Now don't worry," said Andy, jumping on to the raft. "You won't hear for days and days, because we've got to get back home, and then tell our tale and then ships have got to find their way here. So you'll have to wait a long time."
"What shall we say if the enemy want to know where you are?" asked Jill anxiously.
"Just say we have disappeared," said Andy. "And if you like to do another bit of pretending and make a fuss—well, do it!"
"All right," said Jill. "Anyway, you may be quite sure we shan't tell them you've gone off on a raft»
"No—we don't want their seaplanes hunting the sea for us!" said Andy, letting the sail unfurl. "Now—good-bye, Jill! Good-bye, Mary! See you soon!"
"Good-bye, Andy! Good-bye, Tom!" cried the girls, trying to smile cheerfully, though they felt very miserable and lonely to see the boys setting off together. "Good luck!"
Tom pushed out the raft and jumped up on it. He took a paddle and guided it. Andy let the sail billow out. The wind caught it and the little raft leapt along over the waves like a live thing f
"I say! It can get along, can't it!" cried Jill, jumping up and down in excitement. "Look how it bobs over the waves!"
The boys waved wildly to the girls. Little waves splashed over the deck of the raft and wetted the boys' legs. If they ran into a stormy sea they would soon be wet through—but at the moment they cared nothing for what might happen! They were very excited and very anxious to guide their little raft on the right course.
The sail flapped and billowed finely. Andy had rigged it most cleverly, and the wind shot the little craft along swiftly.
"It's going nearly as fast as the ship!" said Tom in delight.
"No—it isn't really," said Andy.-shaking his head. "No raft could ever equal a boat for speed—it's so clumsy and heavy. But I must say our raft isn't bad! Look out—there's a fat wave coming!"
The raft sailed into the wave—slap! It drenched Tom, and he laughed and shook himself like a dog. The sun was out and the boy's clothes soon dried.
The boys looked back at the shore of their island, which now seemed far away. They could just make out the two girls, who had now climbed to the top Of the cliff and were standing there, watching the raft out of sight.
"I hope Jill and Mary will be all right," said Tom. "Poor kids—it was awful having to leave them alone."
"Yes," said Andy. "But it was the only thing to be done. We've happened on very big things, Tom—and so we've got to be big enough and brave enough to meet them."
"Well—I'm not afraid," said Tom stoutly. "And as for you, Andy, I really don't believe anything in the world would frighten you!"
"Oh yes, it would," said Andy. "But I'd not show I was frightened! Look, Tom—you can see all the islands now!"
The boys stood on the raft, holding on to the mast and looked back on the cluster of islands. They lay in the sea together, and looked very small now that the boys were so far off. They could no longer see the girls. And soon even the islands too woukl disappear—then the boys would be quite alone on the wide sea.
"Do you really know which way to go, Andy?" said Tom.
"More or less," said Andy. "I can guide the raft by the sun in the day-time, and by the stars at night. It's a good thing for us that the wind is just in the right direction. I hope it lasts. It's easy enough now—but if the wind changes, things will be very difficult!"
Now the boys could no longer see any land at all. They were alone on the wide green sea. Below them the water was very, very deep. The sea was not rough, but a little choppy, and the raft bobbed like a cork over the waves. Every now and again a wave hopped over the side and wetted the deck of the raft. The boys got used to this and didn't even move when a wave reared its head to run across the raft.
Tom dragged his hand in the cool water. He liked the movement of the raft running over the sea. The sun shone steadily down and the boys became very hot. Tom took off his jersey and hung it safely over the top of the mast, out of reach of the waves.
"Golly! I'm cooking!" he said. Luckily the boys had got hats with them, and these shaded the sun from their heads or they might have felt sick. The sun blazed down, and at last the boys let themselves drop into the sea, holding on to the edge of the raft all the time. This cooled them a little, and they scrambled back wet and panting.
"It would be an awful thing if one of us let go the raft," said Tom. "It's going at such a pace that it would soon leave us behind in the sea and we'd never be found again."
"Well, for goodness' sake hang on tightly then, next time we cool ourselves," said Andy. "What about something to eat?"
They opened a tin of salmon and a tin of pears, and had a good meal, though Tom longed for some bread with the salmon. It was odd sitting there eating on the bobbing raft, all by themselves in the midst of a wide heaving sea.
The day seemed endless—but at last the sun slid down the sky and the sea turned from green to purple in the twilight. "It's not so warm now," said Tom, taking his jersey down from the mast.
"Tom, see if you can have a nap for a while," said Andy. "I don't think we ought both to sleep at once. The wind might change, or a storm might blow up—you sleep now and I'll have a nap later."
Tom wrapped himself in a rug and tried to go to sleep. Andy slipped a rope round his waist and tied him to the box in the middle.
"You might roll off the raft in the middle of the night," he said with a grin. "I shouldn't like to look round and find you gone, Tom!"
Tom lay on his back and looked up at the night sky. It was a clear night, with no moon and the stars shone brightly. Andy pointed out the North Star to Tom.
"That tells me we are still going in the right direction," said Andy. "At this rate we should sight the coast we're heading for in about three or four days."
"Oh—as long as that!" said Tom in great disappointment. "I thought we'd only by a day or two, going at this pace."
"This is a raft, not a sailing-smack," said Andy. "Now go to sleep. I'll wake you if I need you for anything."
Tom slept. He dreamt he was on a swing, going up and down, up and down in the air. It was very pleasant. Then he dreamt he was being scolded by lill for something and she suddenly threw a pail of cold water right over him! He woke with a jump and sat up.
"Did that wave wake you?" said Andy with a grin. "I thought it would. It popped its head up, saw you asleep and jumped right on you!"
Tom laughed and lay down again. He thought about Andy—what a good sort he was—always doing what he felt was best and wisest—never grumbling—always willing to do the hardest job. It was a good thing Tom and the girls had had Andy to help them.
Andy awoke Tom near dawn and told him to sit up and keep watch. "The wind's still right," he said. "Watch it, Tom. You can see the North Star, can't you? I'm so sleepy I can't keep awake much longer."
Andy tied himself up safely, lay down and was asleep as his head touched the rug that made a pillow for him. Tom sat and watched the dawn coming. It was a wonderful sight. First the sky turned to silver and the sea turned to silver too. Soon a pink flush came into the eastern sky and then it changed to a blaze of gold. The sea sparkled and glinted with gold too.
Tom wished he could wake Andy up and make him see the magnificent sight. There was nothing but sea and sky, all glowing with colour. Bat Andy was tired and Tom sat and watched it by himself, half afraid of the strange beauty around Jim.
After a while Tom felt very hungry. He burrowed in the box of food to see what there was. He felt like a meal of tongue or ham. He picked out a tin of tongue and opened it. It smelt delicious.
