"Not a friend of yours, I hope?" said Mr. Chalk, at last.

"Who?" inquired the captain, starting from his reverie.

"The dead man atop of the treasure," replied the other.

"No," said the captain, briefly.

"Is it worth much?" asked Mr. Chalk.

"Roughly speaking, about half a million," responded the captain, calmly.

Mr. Chalk rose and walked up and down the room. His eyes were bright and his face pinker than usual.

"Why don't you get it?" he demanded, at last, pausing in front of his host.

"Why, it ain't mine," said the captain, staring. "D'ye think I'm a thief?"

Mr. Chalk stared in his turn. "But who does it belong to, then?" he inquired.
