He walked on like a man in a dream, and more than half believing that he was really dreaming. He was going eastwards, as he had been going when he had entered the street, but he found it impossible to understand which way his face was turned. He came to Madison Avenue, and knew it at once, recognizing the houses, but though he stood still several minutes at the corner, he could not distinguish which was up town and which down town. He believed that if he could have seen the stars he could have found his way, but the familiar buildings, recognizable in all their features to his practised eye even in the uncertain gaslight, conveyed to him no idea of direction, and the sky was overcast. In despair, at last, he continued in the direction in which he had been going. If he was crossing the avenue he must surely strike the water, whether he went forwards or backwards, and he was positive that he should know the East River from the North River, even on the darkest night, by the look of the piers. But to all intents and purposes, though he knew where he was, he was lost, being deprived of the sense of direction. The confusion increased with the darkness of the next street he traversed, and to his surprise the avenue beyond that did not seem familiar. It was Park Avenue where it is tunnelled along its length for the horse-cars which go to the Central Station. It was very dark, but in a moment he again recognized the houses. By sheer instinct he turned to the right, trusting to luck and giving up all hope of finding his way by any process of reasoning. The darkness, the blow he had received when he had fallen and all that had gone before, combined with the cold he felt, deadened his senses still more.
