“My chronometer!” Captain Mitchell yelled violently at the very moment of being thrust head foremost through a small door into a sort of cell, perfectly black, and so narrow that he fetched up against the opposite wall. The door had been instantly slammed. He knew where they had put him. This was the strong room of the Custom House, whence the silver had been removed only a few hours earlier. It was almost as narrow as a corridor, with a small square aperture, barred by a heavy grating, at the distant end. Captain Mitchell staggered for a few steps, then sat down on the earthen floor with his back to the wall. Nothing, not even a gleam of light from anywhere, interfered with Captain Mitchell’s meditation. He did some hard but not very extensive thinking. It was not of a gloomy cast. The old sailor, with all his small weaknesses and absurdities, was constitutionally incapable of entertaining for any length of time a fear of his personal safety. It was not so much firmness of soul as the lack of a certain kind of imagination--the kind whose undue development caused intense suffering to Senor Hirsch; that sort of imagination which adds the blind terror of bodily suffering and of death, envisaged as an accident to the body alone, strictly--to all the other apprehensions on which the sense of one’s existence is based. Unfortunately, Captain Mitchell had not much penetration of any kind; characteristic, illuminating trifles of expression, action, or movement, escaped him completely. He was too pompously and innocently aware of his own existence to observe that of others. For instance, he could not believe that Sotillo had been really afraid of him, and this simply because it would never have entered into his head to shoot any one except in the most pressing case of self-defence. Anybody could see he was not a murdering kind of man, he reflected quite gravely. Then why this preposterous and insulting charge? he asked himself. But his thoughts mainly clung around the astounding and unanswerable question: How the devil the fellow got to know that the silver had gone off in the lighter? It was obvious that he had not captured it. And, obviously, he could not have captured it! In this last conclusion Captain Mitchell was misled by the assumption drawn from his observation of the weather during his long vigil on the wharf. He thought that there had been much more wind than usual that night in the gulf; whereas, as a matter of fact, the reverse was the case. “How in the name of all that’s marvellous did that confounded fellow get wind of the affair?” was the first question he asked directly after the bang, clatter, and flash of the open door (which was closed again almost before he could lift his dropped head) informed him that he had a companion of captivity. Dr. Monygham’s voice stopped muttering curses in English and Spanish.
