"You'll find 'er a little 'ard, sir," remarked the steersman as he turned over the wheel to Madden. "Good night, sir."

"Good night," returned the American, and he watched the fellow's form disappear in the darkness.

Madden gripped the spokes of the wheel and fell to watching the signal light in the center of the forward bridge and the stern lantern of the distant tug. These two plunging spots in the black void of night he must keep aligned.

The enormous dock leaped and shivered under his feet. Huge waves roared by, of such vastness that Madden could hear their crests crashing and thundering high above the level of the bridge. These moving mountains shook tons of black water into dim, ghostlike spray, and sent it hissing down into cavernous troughs. The weight of the wind-swept spume flashing out of darkness through the binnacle light almost took the boy off his feet. It pounded his oilskin, stung his face. The enormous iron dock groaned and clanged under the mad bastinado. The long arms of the shoring stanchions smote the walls in a kind of terrific anvil chorus to the blaring orchestra of the tempest. The joints of the three huge pontoons sounded as if they were being rent asunder every moment. One minute the great structure would rise dizzily, high into the black blast, a skyscraper flung up on a mountain Madden could look far below on the lights of the struggling Vulcan. Up there the storm yelled and screamed at every corner and brace of the weltering dock, and wrenched at the midget helmsman. Then came the sickening drop, down, down, down, into the profound, and the Vulcan would swing far above her towering consort. For the instant the storm would be blanketed by the prodigious waves. Wild, formless ghosts of foam would stretch wide arms about the falling dock as if they were clasping it into the lowest crypts of the dead, and the night would be filled with a vast and dreadful whispering.

For hours it seemed that every ascent, every descent, must mark the end. But the storm was so terrific, Madden's sense of personal fear was blotted out in the tremendous conflict about him. Indeed, there was something deeply moving, almost gratifying in this elemental rage. Then he discovered that he was taking a part in it. Mechanically he had been straining and pulling at the wheel to hold those signal lights in line. Now he realized that his tiny human force formed a third contender in this vast battle. As he eased the great dock down the rushing sheer of a wave so the shock would not break the straining cable, he had won a point over two violent antagonists. His puny arm, that could raise perhaps two hundred pounds, was lifted against enemies that could fling about billions of tons. Without his force, tug and dock would part company instantly. Each watery mountain that he climbed, each gulf that he fathomed, was a victory over infinite odds.

However, if the man worked with subtlety, the sea likewise worked with subtlety. As the long hours of Madden's watch roared by, one thing was borne in on the youth: the rudder gradually was becoming harder to manage. Madden thought this was caused by the rising storm and strained more rigidly against the wheel.

Then, in the latter part of his vigil, an odd thing happened. A blast of spray struck Madden with some slimy thing that whipped about his neck and chest and almost tore him from the wheel. With convulsive repugnance, he jerked it loose and held the clammy stuff toward the binnacle light. He saw it was seaweed. Presently more strands came beating down on the spume to sting him.

The youth was crouching in his oilskins for protection, when he was surprised by a hand laid on his arm. He looked around and saw it was Deschaillon and the silent Farnol Greer.

"Eet makes bad weather," remarked the Frenchman, peering at the dark rolling Alps about the dock.

"Good thing both of you came," shouted Madden, turning the tiller over to the men. "It's as stiff as cold molasses—how are the sick ones?"
