Buck wondered what Jest Prebol had done to Sadie that she had driven him down there, and he cursed with his own lips, while he stifled in the depths of his own soul another name. His years, his life, had been wasted, just as this man Prebol's life was wasted, just as Slip's life was being wasted. Buck gave himself over to the exquisite torture of memories and reflections. He wondered what had become of the woman for love of whom he had let go all holds and degenerated to this heartless occupation of common gambler? True to Slip, he had watched the river for the stranger whose inquiries had been carried down in fair warning to all the river people--and Buck, suddenly conscious of his own part in that river system, laughed in surprise. "Why," he said to himself, "humans are faithful to one another! It's what they live for, to be faithful to one another!" It was an incredible, but undeniable theory. In spite of his own wilful disbelief in the faith of mankind, here he was sitting by one poor devil's bed while he kept his weather eye out upon the rough river in the interests of another--a murderer! He pondered on the question of whether any one kept faith with him. His mind cried out angrily, "No!" but on second thought, in spite of himself, he realized distinctly that he had let one person's faithlessness overcome his trust of all others. No day on the Mississippi is longer than the cold, bleak monotone of a dry gale out of the north. There is an undertone to the voices which depresses the soul as the rank wind shrivels the body. On whistling wings great flocks of wild fowl come driving down before the wintry gales, or they turn back from the prospect of an early spring. Steamboats are driven into the refuge of landing or eddy, and if the power craft cannot stand the buffetings, much less are the exposed little houseboats, toys of current and breeze, able to escape the resistless blasts. So the wind possesses itself of the whole river breadth and living creatures are driven to shelter. Prebol, shot through and conscious of the reward of his manner of living; Slip, a fugitive under the menace of a murderer's fate; and Buck, given over to melancholy, were but types on the lengths and tributaries of the indifferent flood. Nothing happened, nothing could happen. The arrival of Slip from his restless bunk relieved Buck of his vigil, and he went to bed and slept into the dawn of another day--a day like the previous one, and fit to drive him up the bank, into the woods, and among the fallen branches of rotten trees seeking in physical activity to check the mourning and tauntings of a mind over which he found, as often before, that he had no control.
