"I think I may," he rejoined. "Yes, I am sure I may." His manner cleared, like my own. He replied to my remarks with readiness, and in well-chosen words. Had he much to do there? Yes; that was to say, he had enough responsibility to bear; but exactness and watchfulness were what was required of him, and of actual work--manual labor--he had next to none. To change that signal, to trim those lights, and to turn this iron handle now and then, was all he had to do under that head. Regarding those many long and lonely hours of which I seemed to make so much, he could only say that the routine of his life had shaped itself into that form, and he had grown used to it. He had taught himself a language down here,--if only to know it by sight, and to have formed his own crude ideas of its pronunciation, could be called learning it. He had also worked at fractions and decimals, and tried a little algebra; but he was, and had been as a boy, a poor hand at figures. Was it necessary for him, when on duty, always to remain in that channel of damp air, and could he never rise into the sunshine from between those high stone walls? Why, that depended upon times and circumstances. Under some conditions there would be less upon the Line than under others, and the same held good as to certain hours of the day and night. In bright weather, he did choose occasions for getting a little above these lower shadows; but, being at all times liable to be called by his electric bell, and at such times listening for it with redoubled anxiety, the relief was less than I would suppose. He took me into his box, where there was a fire, a desk for an official book in which he had to make certain entries, a telegraphic instrument with its dial face and needles, and the little bell of which he had spoken. On my trusting that he would excuse the remark that he had been well educated, and (I hoped I might say without offence) perhaps educated above that station, he observed that instances of slight incongruity in such-wise would rarely be found wanting among large bodies of men; that he had heard it was so in workhouses, in the police force, even in that last desperate resource, the army; and that he knew it was so, more or less, in any great railway staff. He had been, when young (if I could believe it, sitting in that hut; he scarcely could), a student of natural philosophy, and had attended lectures; but he had run wild, misused his opportunities, gone down, and never risen again. He had no complaint to offer about that. He had made his bed, and he lay upon it. It was far too late to make another.
