There was a moon, but for the greater part of the time it was hidden by fitful, hurrying clouds, and, as David stumbled forward, at one moment he would see the rails like streaks of silver, and the next would be encompassed in a complete and bewildering darkness. He made his way from tie to tie only by feeling with his foot. After an hour he came to a shed. Whether it was or was not the flag station the conductor had in mind, he did not know, and he never did know. He was too tired, too hot, and too disgusted to proceed, and dropping his suit case he sat down under the open roof of the shed prepared to wait either for the train or daylight. So far as he could see, on every side of him stretched a swamp, silent, dismal, interminable. From its black water rose dead trees, naked of bark and hung with streamers of funereal moss. There was not a sound or sign of human habitation. The silence was the silence of the ocean at night David remembered the berth reserved for him on the train to Tampa and of the loathing with which he had considered placing himself between its sheets. But now how gladly would he welcome it! For, in the sleeping-car, ill-smelling, close, and stuffy, he at least would have been surrounded by fellow-sufferers of his own species. Here his companions were owls, water-snakes, and sleeping buzzards. “I am alone,” he told himself, “on a railroad embankment, entirely surrounded by alligators.” And then he found he was not alone. In the darkness, illuminated by a match, not a hundred yards from him there flashed suddenly the face of a man. Then the match went out and the face with it. David noted that it had appeared at some height above the level of the swamp, at an elevation higher even than that of the embankment. It was as though the man had been sitting on the limb of a tree. David crossed the tracks and found that on the side of the embankment opposite the shed there was solid ground and what once had been a wharf. He advanced over this cautiously, and as he did so the clouds disappeared, and in the full light of the moon he saw a bayou broadening into a river, and made fast to the decayed and rotting wharf an ocean-going tug. It was from her deck that the man, in lighting his pipe, had shown his face. At the thought of a warm engine-room and the company of his fellow creatures, David's heart leaped with pleasure. He advanced quickly. And then something in the appearance of the tug, something mysterious, secretive, threatening, caused him to halt. No lights showed from her engine-room, cabin, or pilot-house. Her decks were empty. But, as was evidenced by the black smoke that rose from her funnel, she was awake and awake to some purpose. David stood uncertainly, questioning whether to make his presence known or return to the loneliness of the shed. The question was decided for him. He had not considered that standing in the moonlight he was a conspicuous figure. The planks of the wharf creaked and a man came toward him.
