"How do you do, Mrs. Mallory? Glad to see you."

The miners from Frozen Gulch were grouped together on the lower deck. At sight of the man with the suitcase a sullen murmur rose among them. Those in the rear pushed forward and closed the lane leading to the cabins. One of the miners was flung roughly against the new passenger. With a wide, powerful sweep of his arm the man who had just come aboard hurled the miner back among his companions.

"Gangway!" he said brusquely, and as he strode forward did not even glance in the direction of the angry men pressing toward him.

"Here. Keep back there, you fellows. None of that rough stuff goes," ordered the mate sharply.

The big Cornishman who had been tossed aside crouched for a spring. He launched himself forward with the awkward force of a bear. The suitcase described a whirling arc of a circle with the arm of its owner as the radius. The bag and the head of the miner came into swift impact. Like a bullock which has been pole-axed the man went to the floor. He turned over with a groan and lay still.

The new passenger looked across the huge, sprawling body at the group of miners facing him. They glared in savage hate. All they needed was a leader to send them driving at him with the force of an avalanche. The man at whom they raged did not give an inch. He leaned forward slightly, his weight resting on the balls of his feet, alert to the finger tips. But in his eyes a grim little smile of derisive amusement rested.

"Next," he taunted.

Then the mate got busy. He hustled his stevedores forward in front of the miners and shook his fist in their faces as he stormed up and down. If they wanted trouble, by God! it was waiting for 'em, he swore in apoplectic fury. The Hannah was a river boat and not a dive for wharf rats. No bunch of roughnecks could come aboard a boat where he was mate and start anything. They could not assault any passengers of his and make it stick.

The man with the suitcase did not wait to hear out his tirade. He followed the purser to his stateroom, dropped his baggage beside the berth, and joined the Kusiak group on the upper deck.

They greeted him eagerly, a little effusively, as if they were anxious to prove themselves on good terms with him. The deference they paid and his assured acceptance of it showed him to be a man of importance. But apart from other considerations, he dominated by mental and physical virility the circle of which he instantly became the center. Only Mrs. Mallory held her own, and even she showed a quickened interest. Her indolent, half-disdainful manner sheathed a soft sensuousness that held the provocation of sex appeal.

"What was the matter?" asked Selfridge. "How did the trouble start?"

The big man shrugged his shoulders. "It didn't start. Some of the outfit thought they were looking for a row, but they balked on the job when Trelawney got his." Turning to Mrs. Mallory, he changed the subject abruptly. "Did you have a good time down the river?"

Gordon, as he watched from a little distance, corrected earlier impressions. This man had passed the thirties. Salt and pepper sprinkled the temples of his strong, lean head. He had the thick neck and solid trunk of middle life, but he carried himself so superbly that his whole bearing denied that years could touch his splendid physique. The suit he wore was a wrinkled corduroy, with trouser legs thrust into high-laced boots. An outdoor tan had been painted upon his face and neck, from the point where the soft flannel shirt fell away to show the fine slope of the throat line to the shoulders.

Strong had stepped to the wharf to talk with an old acquaintance, but when the boat threw out a warning signal he made a hurried good-bye and came on board. He rejoined Elliot.

"Well, what d'you think of him? Was I right?"

The young man had already guessed who this imperious stranger was. "I never saw anybody get away with a hard job as easily as he did that one. You could see with half an eye that those fellows meant fight. They were all primed for it—and he bluffed them out."

"Bluffed them—huh! If that's what you call bluffing. I was where I could see just what happened. Colby Macdonald wasn't even looking at Trelawney, but you bet he saw him start. That suitcase traveled like a streak of light. You'd 'a' thought it weighed about two pounds. That ain't all either. Mac used his brains. Guess what was in that grip."

"The usual thing, I suppose."

"You've got another guess—packed in among his socks and underwear was about twenty pounds of ore samples. The purser told me. It was that quartz put Trelawney to sleep so thorough that he'd just begun to wake up when I passed a minute ago."

The young man turned his eyes again upon the big Canadian Scotchman. He was talking with Mrs. Mallory, who was leaning back luxuriously in a steamer chair she had brought aboard at St. Michael's. It would have been hard to conceive a contrast greater than the one between this pampered heiress of the ages and the modern business berserk who looked down into her mocking eyes. He was the embodiment of the dominant male,—efficient to the last inch of his straight six feet. What he wanted he had always taken, by the sheer strength that was in him. Back of her smiling insolence lay a silken force to match his own. She too had taken what she wanted from life, but she had won it by indirection. Manifestly she was of those women who conceive that charm and beauty are tools to bend men to their wills. Was it the very width of the gulf between them that made the appeal of the clash in the sex duel upon which they had engaged?

The dusky young woman with the magazine was the first of those on the upper deck to retire for the night. She flitted so quietly that Gordon did not notice until she had gone. Mrs. Selfridge and her friends disappeared with their men folks, calling gay good-nights to one another as they left.

Macdonald and Mrs. Mallory still talked. After a time she too vanished.

The big promoter leaned against the deck rail, where he was joined by Selfridge. For a long time they talked in low voices. The little man had most to say. His chief listened, but occasionally interrupted to ask a sharp, incisive question.

Elliot, sitting farther forward with Strong, judged that Selfridge was making a report of his trip. Once he caught a fragment of their talk, enough to confirm this impression.

"Did Winton tell you that himself?" demanded the Scotchman.

The answer of his employee came in a murmur so low that the words were lost. But the name used told Gordon a good deal. The Commissioner of the General Land Office at Washington signed his letters Harold B. Winton.

Strong tossed the stub of his cigarette overboard and nodded good-night. A glance at his watch told Elliot that it was past two o'clock. He rose, stretched, and sauntered back to his stateroom.

The young man had just taken off his coat when there came the hurried rush of trampling feet upon the hurricane deck above. Almost instantly he heard a cry of alarm. Low voices, quick with suppressed excitement, drifted back to him. He could hear the shuffling of footsteps and the sound of heavy bodies moving.

Some one lifted a frightened shout. "Help! Help!" The call had come, he thought, from Selfridge.

Gordon flung open the door of his room, raced along the deck, and took the stairs three at a time. A huddle of men swayed and shifted heavily in front of him. So close was the pack that the motion resembled the writhing of some prehistoric monster rather than the movements of individual human beings. In that half-light tossing arms and
