I.

The steamer Silveropolis was sharply and steadily cleaving the broad, placid shallows of the Sacramento River. A large wave like an eagre, diverging from its bow, was extending to either bank, swamping the tules and threatening to submerge the lower levees.

The great boat itself--a vast but delicate structure of airy stories, hanging galleries, fragile colonnades, gilded cornices, and resplendent frescoes--was throbbing throughout its whole perilous length with the pulse of high pressure and the strong monotonous beat of a powerful piston. Floods of foam pouring from the high paddle-boxes on either side and reuniting in the wake of the boat left behind a track of dazzling whiteness, over which trailed two dense black banners flung from its lofty smokestacks.

Mr. Jack Hamlin had quietly emerged from his stateroom on deck and was looking over the guards. His hands were resting lightly on his hips over the delicate curves of his white waistcoat, and he was whistling softly, possibly some air to which he had made certain card-playing passengers dance the night before. He was in comfortable case, and his soft brown eyes under their long lashes were veiled with gentle tolerance of all things. He glanced lazily along the empty hurricane deck forward; he glanced lazily down to the saloon deck below him. Far out against the guards below him leaned a young girl. Mr. Hamlin knitted his brows slightly.

He remembered her at once. She had come on board that morning with one Ned Stratton, a brother gambler, but neither a favorite nor intimate of Jack's. From certain indications in the pair, Jack had inferred that she was some foolish or reckless creature whom "Ed"had "got on a string," and was spiriting away from her friends and family. With the abstract morality of this situation Jack was not in the least concerned. For himself he did not indulge in that sort of game; the inexperience and vacillations of innocence were apt to be bothersome, and besides, a certain modest doubt of his own competency to make an original selection had always made him prefer to confine his gallantries to the wives of men of greater judgment than himself who had. But it suddenly occurred to him that he had seen Stratton quickly slip off the boat at the last landing stage. Ah! that was it; he had cast away and deserted her.

It was an old story. Jack smiled. But he was not greatly amused with Stratton.

She was very pale, and seemed to be clinging to the network railing, as if to support herself, although she was gazing fixedly at the yellow glancing current below, which seemed to be sucked down and swallowed in the paddle-box as the boat swept on. It certainly was a fascinating sight--this sloping rapid, hurrying on to bury itself under the crushing wheels. For a brief moment Jack saw how they would seize anything floating on that ghastly incline, whirl it round in one awful revolution of the beating paddles, and then bury it, broken and shattered out of all recognition, deep in the muddy undercurrent of the stream behind them.

She moved away presently with an odd, stiff step, chafing her gloved hands together as if they had become stiffened too in her rigid grasp of the railing. Jack leisurely watched her as she moved along the narrow strip of deck. She was not at all to his taste,--a rather plump girl with a rustic manner and a great deal of brown hair under her straw hat. She might have looked better had she not been so haggard. When she reached the door of the saloon she paused, and then, turning suddenly, began to walk quickly back again. As she neared the spot where she had been standing her pace slackened, and when she reached the railing she seemed to relapse against it in her former helpless fashion. Jack became lazily interested. Suddenly she lifted her head and cast a quick glance around and above her. In that momentary lifting of her face Jack saw her expression. Whatever it was, his own changed instantly; the next moment there was a crash on the lower deck. It was Jack who had swung himself over the rail and dropped ten feet, to her side. But not before she had placed one foot in the meshes of the netting and had gripped the railing for a spring.

The noise of Jack's fall might have seemed to her bewildered fancy as a part of her frantic act, for she fell forward vacantly on the railing. But by this time Jack had grasped her arm as if to help himself to his feet.

"I might have killed myself by that foolin', mightn't I?" he said cheerfully.

The sound of a voice so near her seemed to recall to her dazed sense the uncompleted action his fall had arrested. She made a convulsive bound towards the railing, but Jack held her fast.

"Don't," he said in a low voice, "don't, it won't pay. It's the sickest game that ever was played by man or woman. Come here!"He drew her towards an empty stateroom whose door was swinging on its hinges a few feet from them. She was trembling violently; he half led, half pushed her into the room, closed the door and stood with his back against it as she dropped into a chair. She looked at him vacantly; the agitation she was undergoing inwardly had left her no sense of outward perception.

"You know Stratton would be awfully riled," continued Jack easily.

"He's just stepped out to see a friend and got left by the fool boat. He'll be along by the next steamer, and you're bound to meet him in Sacramento."Her staring eyes seemed suddenly to grasp his meaning. But to his surprise she burst out with a certain hysterical desperation, "No!

no! Never! NEVER again! Let me pass! I must go," and struggled to regain the door. Jack, albeit singularly relieved to know that she shared his private sentiments regarding Stratton, nevertheless resisted her. Whereat she suddenly turned white, reeled back, and sank in a dead faint in the chair.
