The children did not have a very good night after all, for they were far too excited to sleep. They had all rowed in the stolen boat to their own island, and had landed there, tied up the boat and gone to their shack.
They slept rather late the next morning, for not one of them had gone to sleep before midnight—and they were awakened by the throbbing noise that they had heard two nights before!
"The seaplane again!" said Andy, waking up at once and leaping to his feet. He ran to the open doorway of the hut, and was just in time to see the plane soar overhead. Then it went round in great circles ready to land on the smooth water outside the second island.
"That means we can't get away to-day," said Tom at once. "We simply must get food into the boat—and we can't if that plane is there."
"No—we can't," said Andy. "But I tell you what we might do, Tom. We might row to the third island, tie our boat up in a hidden place, creep to the top of that cliff, and try to take a few photographs of the submarine bay! We meant to take some photos, you know."
"Yes—we could do that." said Tom. "we'll have to be pretty careful, though."
"We will be," said Andy. "Jill, what is there for breakfast?"
There were tinned sausages and baked beans and tomato sauce. Jill proudly produced some little rolls of bread she had made, too. They all ate in silence, thinking over everything that had happened.
"That seaplane may not stay long," said Andy. "It didn't last time. I expect k has come to add to the stores—or maybe take away from them. It will be busy that side of the island—so we will row round the after side, where we wont be seen, go across to the third one. and tie up there. You girls must stay here."
"Oh, you always have the exciting things to do." sighed Mary. "Can't we really come with you? I don't see why we can't."
