It filled all at once with a sound as of a single loud drum-tap. Decoud went back to the ravine. Nostromo, at the tiller, looked back from time to time at the vanishing mass of the Great Isabel, which, little by little, merged into the uniform texture of the night. At last, when he turned his head again, he saw nothing but a smooth darkness, like a solid wall.
Then he, too, experienced that feeling of solitude which had weighed heavily on Decoud after the lighter had slipped off the shore. But while the man on the island was oppressed by a bizarre sense of unreality affecting the very ground upon which he walked, the mind of the Capataz of the Cargadores turned alertly to the problem of future conduct. Nostromo's faculties, working on parallel lines, enabled him to steer straight, to keep a look-out for Hermosa, near which he had to pass, and to try to imagine what would happen tomorrow in Sulaco. Tomorrow, or, as a matter of fact, today, since the dawn was not very far, Sotillo would find out in what way the treasure had gone. A gang of cargadores had been employed in loading it into a railway truck from the Custom House storerooms, and running the truck on to the wharf. There would be arrests made, and certainly before noon Sotillo would know in what manner the silver had left Sulaco, and who it was that took it out.
Nostromo's intention had been to sail right into the harbour; but at this thought by a sudden touch of the tiller the threw the lighter into the wind and checked her rapid way. His reappearance with the very boat would raise suspicions, would cause surmises, would absolutely put Sotillo on the track. He himself would be arrested; and once in the Calabozo there was no saying what they would do to him to make him speak. He trusted himself, but he stood up to look round. Near by, Hermosa showed low its white surface as flat as a table, with the slight run of the sea raised by the breeze washing over its edges noisily. The lighter must be sunk at once.
He allowed her to drift with her sail aback. There was already a good deal of water in her. He allowed her to drift towards the harbour entrance, and, letting the tiller swing about, squatted down and busied himself in loosening the plug. With that out she would fill very quickly, and every lighter carried a little iron ballast -- enough to make her go down when full of water. When he stood up again the noisy wash about the Hermosa sounded far away, almost inaudible; and already he could make out the shape of land about the harbour entrance. This was a desperate affair, and he was a good swimmer. A mile was nothing to him, and he knew of an easy place for landing just below the earthworks of the old abandoned fort. it occurred to him with a peculiar fascination that this fort was a good place in which to sleep the day through after so many sleepless nights.
With one blow of the tiller he unshipped for the purpose, he knocked the plug out, but did not take the trouble to lower the sail. He felt the water welling up heavily about his legs before he leaped on to the taffrail.
There, upright and motionless, in his shirt and trousers only, he stood waiting. When he had felt her settle he sprang far away with a mighty splash.
At once he turned his head. The gloomy, clouded dawn from behind the mountains showed him on the smooth waters the upper corner of the sail, a dark wet triangle of canvas waving slightly to and fro. He saw it vanish, as if jerked under, and then struck out for the shore.
