ADAM LAREY gazed with hard and wondering eyes down the silent current of the red river upon which he meant to drift away into the desert.The Rio Colorado was no river to trust. It chafed at its banks as if to engulf them; muddy and thick it swirled and glided along in flood, sweeping in curves back and forth from Arizona to California shore. Majestic and gleaming under the hot sky, it swung southward between wide green borders of willow and cottonwood toward a stark and naked upflung wilderness of mountain peaks, the red ramparts of the unknown and trackless desert.Adam rushed down the bank and threw his pack into a boat. There his rapid action seemed checked by the same violence that had inspired his haste. He looked back, up at the dusty adobe town of Ehrenberg, asleep now under the glaring noonday heat. It would not wake out of that siesta till the return of the weary gold diggers, or the arrival of the stagecoach or the steamer. A tall Indian, swarthy and unkempt, stood motionless in the shade of a wall, watching stolidly.Adam broke down then. Sobs made his utterance incoherent. "Guerd is no brother-of mine-any more!" he burst out. His accent was one of humiliation and cheated love. "And as for-for her-I'll never-never think of her-again."When once more he turned to the river, a spirit wrestled with the emotion that had unnerved him. Adam Larey appeared to be a boy of eighteen, with darkly tanned, clear-cut, and comely face, and a lofty stature, straight and spare and wide. Untying the boat from its mooring, he became conscious of a singular thrill. Sight of the silent river fascinated him. If it had been drink that had fortified his reckless resolve, it was some strange call to the wildness in him that had stirred exaltation in the prospect of adventure. But there was more. Never again to be dominated by that selfish Guerd, his brother who had taken all and given nothing! Guerd would be stung by this desertion. Perhaps he would be sorry. That thought gave Adam a pang. Long habit of being influenced, and strength of love fostered in playmate days, these made him waver. But the tide of resentment surged up once more; and there flowed the red Colorado, rolling away to the southwest, a gateway to the illimitable wastes of desert land, with its mystery, its adventure, its gold and alluring freedom."I'll go," he declared, passionately, and with a shove he sent the boat adrift and leaped over the bow to the rowing seat. The boat floated lazily, half circling, till it 5edged into the current; then, as if grasped by unseen power, it glided downstream. Adam seemed to feel the resistless current of this mysterious river take hold of his heart. There would be no coming back-no breasting that mighty flood with puny oars. The moment was sudden and poignant in its revelation. How swiftly receded the cluster of brown adobe huts, the somber, motionless Indian! He had left Ehrenberg behind, and a brother who was his only near relative, and a little sum of love that had failed him.
