The crew stared at the approaching light as stricken birds in a snake's cage. Just then Caradoc said in a low tone. "Let every man slide into the water and swim for the Vulcan."
The men in the stern slipped into the sea first with muffled splashes. The men amidship climbed over the side and went in headfirst. The oarsmen shipped their oars and took the water. Madden made a long dive over the side and shot well away from the little boat. When he came up, he looked around. The fringe of light was just playing on the bow when Caradoc leaped. According to English traditions, he was the last man to leave his vessel, even though it were only a dinghy.
An instant later, a queer metallic ripping sound broke out in the mother ship. Madden looked back quickly. From the top deck there was a jet of fire, as if someone were turning a hose of flame in the direction of the small boat. Leonard looked back at the dinghy. It appeared as if the ray of light were beating the little vessel into splinters. It seemed to crumble into itself, to wither, to go to dust, and the water beneath it beat up in a froth through its shattered hull.
A head bobbed up near Madden, and Caradoc's voice observed collectedly.
"They're chewing it up with a machine gun. You'd better dive again—travel most of the way to the tug under water. They'll be picking us up, one at a time, in a moment, with the same stream of steel."
CHAPTER XVIII
NERVE VERSUS GUNPOWDER
Fifteen minutes later a dozen men were kicking exhaustedly in the water on the port side of the Vulcan, shouting in urgent voices for ropes. A few were already clambering up the bobstays. There was no reply from the utterly terrorized men on the tug, then came the whiz of missiles thrown through the air.
"Hogan! Mulcher! Galton! Ropes! Give us your ladder!" bawled Madden at the top of his authority.
