[Illustration: JUDGE BLACKSTONE REFUSES TO CLIMB TO THE MIZZENTOP]

"Whomsoever I tell to go, shall go," put in Holmes, firmly. "I am
commander of this ship. It will pay you to remember that, Judge
Blackstone."

"And I am the Court of Appeals," retorted Blackstone, hotly. "Bear that in
mind, captain, when you try to send me up. I'll issue a writ of _habeas
corpus_ on my own body, and commit you for contempt."

"There's no use of sending the Judge, anyhow," said Raleigh, fearing by
the glitter that came into the eye of the commander that trouble might
ensue unless pacificatory measures were resorted to. "He's accustomed to
weighing everything carefully, and cannot be rushed into a decision. If he
saw any evidence, he'd have to sit on it a week before reaching a
conclusion. What we need here more than anything else is an expert seaman,
a lookout, and I nominate Shem. He has sailed under his father, and I have
it on good authority that he is a nautical expert."

Holmes hesitated for an instant. He was considering the necessity of
disciplining the recalcitrant Blackstone, but he finally yielded.

"Very well," he said. "Shem be it. Bo'sun, pipe Shem on deck, and tell him
that general order number one requires him to report at the mizzentop
right away, and that immediately he sees anything he shall come below and
make it known to me. As for the rest of us, having a very considerable
appetite, I do now decree that it is dinner-time. Shall we go below?"
