"And you must swear to keep it if it's told you. That's what she means.
I've had to and so has Stobell."

A fierce grunt from Mr. Stobell, who was still suffering from the
remembrance of an indignity against which he had protested in vain, came
as confirmation. Then the marvelling Mr. Chalk rose, and instructed by
Miss Vickers took an oath, the efficacy of which consisted in a fervent
hope that he might die if he broke it.

"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.
