It was in this state that he found himself one day upon a Rhine boat, bound for Mainz. He had a very vague notion of how he had managed to get there; he had no notion at all of his reason for travelling in that direction. It dawned upon him by degrees that he had chosen the very same route, and made the same stoppages, as he had done when he was a mere boy, travelling with his father upon the Continent. Richard and his mother had not been there; Brian and Mr. Luttrell had spent a particularly happy time together, and the remembrance of it soothed his troubled brain, and caused his eye to rest with a sort of dreamy pleasure upon the scene around him. It was rather late for a Rhine expedition, and the boat was not at all full. Brian rather thought that the journey with his father had been taken at about the same time of the year--perhaps even a little later. He had a special memory of the wealth of Virginian creeper which covered the buildings near Coblentz. He looked out for it when the boat stopped at the landing-stage, and thought of the time when he had wandered hand-in-hand with his father in the pleasant Anlagen on the river banks, and gathered a scarlet trail of leaves from the castle walls. The leaves were in their full autumnal glory now; he must have been there at about the same season when he was a boy. After determining this fact to his satisfaction, Brian went back to the seat that he had found for himself at the end of the boat, and began once more to watch the gliding panorama of "castled crag" and vine-clad slope, which was hardly as familiar to him as it is to most of us. But, after all, Drachenfels and Ehrenbreitstein had no great interest for him. He had no great interest in anything. Perhaps the little excitement and bustle at the landing-places pleased him more than the scenery itself--the peasants shouting to each other from the banks, the baskets of grapes handed in one after another, the patient oxen waiting in the roads between the shafts; these were sights which made no great claim upon his attention and were curiously soothing to his jaded nerves. He watched them languidly, but was not sorry from time to time to close his eyes and shut out his surroundings altogether. The worst of it was, that when he had closed his eyes for a little time, the scene in the wood always came back to him with terrible distinctness, or else there rose up before his eyes a picture of that darkened room, with Richard's white face upon the pillow and his mother's dark form and outstretched hand. These were the memories that would not let him sleep at night or take his ease in the world by day. He could not forget the past.
