"But why?" inquired Mr. Chalk, after they had paced once up and down the deck in silence.

"It's the mystery we don't like," said Brisket, at last. "How are we to know what desperate venture you are going to let us in for? Follow you faithful we will, but we don't like going in the dark; it ain't quite fair to us."

"There's not the slightest danger in the world," said Mr. Chalk, with impressive earnestness.

"But there's a mystery; you can't deny that," said the captain.

Mr. Chalk cleared his throat. "It's a secret," he said, slowly.

"From me?" inquired the captain, in reproachful accents.

"It isn't my secret," said Mr. Chalk. "So far as I'm concerned I'd tell you with pleasure."

The captain slowly withdrew his arm from Mr. Chalk's, and moving to the side leaned over it with his shoulders hunched. Somewhat moved by this display of feeling, Mr. Chalk for some time hesitated to disturb him, and when at last he did steal up and lay a friendly hand on the captain's shoulder it was gently shaken off.

"Secrets!" said Brisket, in a hollow voice. "From me! I ain't to be trusted?"

"It isn't my doing," said Mr. Chalk.
