We went in again, shut the door, and resumed our seats. I was thinking how best to improve this advantage, if it might be called one, when he took up the conversation in such a matter-of-course way, so assuming that there could be no serious question of fact between us, that I felt myself placed in the weakest of positions. "By this time you will fully understand, sir," he said, "that what troubles me so dreadfully is the question, What does the spectre mean?" I was not sure, I told him, that I did fully understand. "What is its warning against?" he said, ruminating, with his eyes on the fire and only by times turning them on me. "What is the danger? Where is the danger? There is danger overhanging somewhere on the line. Some dreadful calamity will happen. It is not to be doubted this third time after what has gone before. But surely this is a cruel haunting of me. What can I do?" He pulled out his handkerchief and wiped the drops from his heated forehead. "If I telegraph danger on either side of me, or on both, I can give no reason for it," he went on, wiping the palms of his hands. "I should get into trouble and do no good. They would think I was mad. This is the way it would work--Message: 'Danger! Take care!' Answered: 'What danger? Where?' Message: 'Don't know. But for God's sake, take care!' They would discharge me. What else could they do?" His pain of mind was most pitiable to see. It was the mental torture of a conscientious man oppressed beyond endurance by an unintelligible responsibility involving life. "When it first stood under the danger-light," he went on, putting his dark hair back from his head and drawing his hands outward across and across his temples in an extremity of feverish distress, "why not tell me where that accident was to happen, if it must happen? Why not tell me how it could be averted, if it could have been averted? When on its second coming it hid its face, why not tell me, instead, 'She is going to die. Let them keep her at home?' If it came, on those two occasions, only to show me that its warnings were true and so to prepare me for the third, why not warn me plainly now? And I, Lord help me! A mere poor signal man in this solitary station! Why not go to somebody with credit to be believed and power to act?"
