Herr Professor, Doctor, So-and-so? The "Doctor" was by brevet or vaticination, to make the grade easier to my pocket. One feels so intimately assured that he is made up, in part, of shreds and leavings of the past, in part of the interpolations of other people, that an honest man would be slow in saying _yes_ to such a question. But "my name is So-and-so" is a safe answer, and I gave it. While I had been romancing with myself, the street-lamps had been lighted, and it was under one of these detectives that have robbed the Old Road of its privilege of sanctuary after nightfall that I was ambushed by my foe. The inexorable villain had taken my description, it appears, that I might have the less chance to escape him. Dr. Holmes tells us that we change our substance, not every seven years, as was once believed, but with every breath we draw. Why had I not the wit to avail myself of the subterfuge, and, like Peter, to renounce my identity, especially, as in certain moods of mind, I have often more than doubted of it myself? When a man is, as it were, his own front-door, and is thus knocked at, why may he not assume the right of that sacred wood to make every house a castle, by denying himself to all visitations? I was truly not at home when the question was put to me, but had to recall myself from all out-of-doors, and to piece my self-consciousness hastily together as well as I could before I answered it. I knew perfectly well what was coming. It is seldom that debtors or good Samaritans waylay people under gaslamps in order to force money upon them, so far as I have seen or heard. I was also aware, from considerable experience, that every foreigner is persuaded that, by doing this country the favor of coming to it, he has laid every native thereof under an obligation, pecuniary or other, as the case may be, whose discharge he is entitled to on demand duly made in person or by letter. Too much learning (of this kind) had made me mad in the provincial sense of the word. I had begun life with the theory of giving something to every beggar that came along, though sure of never finding a native-born countryman among them. In a small way, I was resolved to emulate Hatem Tai's tent, with its three hundred and sixty-five entrances, one for every day in the year,--I know not whether he was astronomer enough to add another for leap-years. The beggars were a kind of German-silver aristocracy; not real plate, to be sure, but better than nothing. Where everybody was overworked, they supplied the comfortable equipoise of absolute leisure, so æsthetically needful. Besides, I was but too conscious of a vagrant fiber in myself, which too often thrilled me in my solitary walks with the temptation to wander on into infinite space, and by a single spasm of resolution to emancipate myself from the drudgery of prosaic serfdom to respectability and the regular course of things. This prompting has been at times my familiar
