"Fellows, we're not sailors. The launch has been carried away by the tide!"
"Carried away by the tide?" repeated Widdy, wonderingly, as he stumped forward. "It couldn't be! She was well fastened, and the kedge anchor was out of reach of high water."
"But she's gone!" declared Dick.
"Maybe we're at the wrong place," suggested Paul.
"This is where we landed," insisted Henry.
"It sure is," agreed Beeby. "I remember it, for I took a picture of the launch as it was drawn up on the beach, and I stood near this big shell," and lie pointed to one of peculiar formation.
"Then Captain Barton must have come ashore and got the boat," said Frank Bender.
Dick glanced across the bay. There was a wide expanse of water, but nothing was visible on it. A cry of fear and wonder came to his lips.
"Fellows!" he exclaimed, "my yacht is also gone!"
"Gone?" echoed the others. Silently Dick pointed to the place where the Albatross had been anchored. There was no mistaking it, for the craft had been just opposite where the launch landed. But the yacht was not there, and a rapid survey of the shore in both directions did not disclose either her or the launch.
"Fellows, we're marooned on this island!" spoke Dick, solemnly.
