Captain Barton arrested his course as formerly—the unaccountable nature of the occurrence filled him with vague and disagreeable sensations—and yielding to the excitement that was gaining upon him, he shouted sternly, “Who goes there?” The sound of one’s own voice, thus exerted, in utter solitude, and followed by total silence, has in it something unpleasantly dismaying, and he felt a degree of nervousness which, perhaps, from no cause had he ever known before. To the very end of this solitary street the steps pursued him—and it required a strong effort of stubborn pride on his part, to resist the impulse that prompted him every moment to run for safety at the top of his speed. It was not until he had reached his lodging, and sate by his own fire-side, that he felt sufficiently reassured to rearrange and reconsider in his own mind the occurrences which had so discomposed him. So little a matter, after all, is sufficient to upset the pride of scepticism and vindicate the old simple laws of nature within us. CHAPTER II. THE WATCHER. Mr. Barton was next morning sitting at a late breakfast, reflecting upon the incidents of the previous night, with more of inquisitiveness than awe, so speedily do gloomy impressions upon the fancy disappear under the cheerful influence of day, when a letter just delivered by the postman was placed upon the table before him. There was nothing remarkable in the address of this missive, except that it was written in a hand which he did not know—perhaps it was disguised—for the tall narrow characters were sloped backward; and with the self-inflicted suspense which we often see practised in such cases, he puzzled over the inscription for a full minute before he broke the seal. When he did so, he read the following words, written in the same hand:— “Mr. Barton, late captain of the ‘Dolphin,’ is warned of DANGER. He will do wisely to avoid —— street—[here the locality of his last night’s adventure was named]—if he walks there as usual he will meet with something unlucky—let him take warning, once for all, for he has reason to dread “THE WATCHER.” Captain Barton read and re-read this strange effusion; in every light and in every direction he turned it over and over; he examined the paper on which it was written, and scrutinized the hand-writing once more. Defeated here, he turned to the seal; it was nothing but a patch of wax, upon which the accidental impression of a thumb was imperfectly visible. There was not the slightest mark, or clue of any kind, to lead him to even a guess as to its possible origin. The writer’s object seemed a friendly one, and yet he subscribed himself as one whom he had “reason to dread.” Altogether the letter, its author, and its real purpose were to him an inexplicable puzzle, and one, moreover, unpleasantly suggestive, in his mind, of other associations connected with his last night’s adventure.
