"But what's it all about?" he inquired, plaintively.

Mr. Tredgold conferred with Miss Vickers, and that lady, after a moment's hesitation, drew a folded paper from her bosom and beckoned to Mr. Chalk. With a cry of amazement he recognised the identical map of Bowers's Island, which he had last seen in the hands of its namesake. It was impossible to mistake it, although an attempt to take it in his hand was promptly frustrated by the owner.

"But Captain Bowers said that he had burnt it," he cried.

Mr. Tredgold eyed him coldly. "Burnt what?" he inquired.

"The map," was the reply.

"Just so," said Tredgold. "You told me he had burnt a map."

"Is this another, then?" inquired Mr. Chalk.

"P'r'aps," said Miss Vickers, briefly.

"As the captain said he had burnt his, this must be another," said Tredgold.

"Didn't he burn it, then?" inquired Mr. Chalk.
