"Then stay where you are, for you're covered!" ordered the same voice in a frenzied tone. "We're not going to have you aboard. Signal the destroyer to make off at top speed and we'll leave you when she is out of sight. Refuse, and we kill you at once. Refuse, and you lose your life."

"Lower your gangway, and stop your nonsense," Dave ordered, angrily. "You're dealing with the United States Navy, and your orders cannot control our conduct."

"Then you are a dead man, at once!" declared the voice of the unseen speaker.

Unnoticed by others, Darrin had given a hand signal to a petty officer in the bow of the launch.

"If you do not lower your side gangway at once, we shall find our own means for boarding," Dave shouted, wrathfully. "Instantly, sir!"

Thereupon half a dozen heads appeared over a bulwark above. As many rifle muzzles were thrust over the edge of the bulwark and a prompt fire began.

Disdaining to draw his automatic Darrin stood up in the launch, the center of such a hail of bullets that his continued existence seemed incredible. Above the reports of the rifles could be heard the voice of Ensign Peters as he directed the swinging around of the launch.

R-r-r-r-rip! The launch's machine gun came swiftly into play. Bullets rattled against the iron sides of the ship.

Four of the six seamen on her deck were seen to fall back; the remaining two fled as fast as they could go.

Then the muzzle of the machine gun was swung, and a hundred little missiles were driven through the wheel-house.
