With the utmost horror, Madden saw every tiny port spouting continuous flame in his direction. Steel frothed the sea all around the Vulcan. Missiles struck the little tug and glanced off with sharp musical twangs. The crew of the little boat, who swarmed on deck, wonderstruck at the battle of the giants, suddenly darted to cover with wild yells.

"They're crazy! They're daft!" screamed Madden. "Shooting at us! What's the matter with 'em?"

Caradoc, also, seemed to share the madness. He suddenly spun his wheel to the left, veered in a sharp circle, and dashed straight toward the course of the Panther into the thickest of the hail. Leonard stood beside him, frozen stiff, when straight ahead, he suddenly saw a periscope show for an instant, then disappear in a little swirl of water. The submarine had come into the action.

The tug rushed straight through the bullet-rumpled water to the point where the metal fin had disappeared, like a terrier dashing at a rathole.

With the disappearance of the submarine's "eye," the fusillade ceased abruptly. The great cannon were firing more slowly now and there came short intervals of comparative silence in the battle.

From the bridge Caradoc bellowed fiercely at his men: "Spread around the rail—keep a sharp lookout for the submarine!" The crew came back with a will now that they learned the bombardment had not been intended for them.

In the meantime the tiny David had put the great Goliath to flight. The Panther was endeavoring to save herself. She veered out of the thundering battle line and zigzagged easterly, in full flight from any enemy that she could almost drop down one of her smokestacks.

And the little Vulcan swung about in an effort to keep up with her principal. On she rushed, shaking and puffing like a locomotive, her bright flags flying the submarine warning, as if the speeding giant ahead of her were likely to forget it.

Suddenly Hogan bawled out: "By th' port! By th' port, sir! There she rises!"

Another shrill storm from the giant showed that the gunners aboard the Panther also saw the periscope.
