With admirable subtlety and suggestiveness, Mr. Hawthorne illustrates this subject in that _fantasiestück_ of his, called “David Swan.” A young man of that name falls asleep on the roadside, of a summer’s day, and _we_ see, what he sees not, nor dreams of happening to him, a series of incidents that go near to alter the current of his being, and very near, in one instance, to stop altogether its earthly course. When he awakes from that sound sleep, and hies him cheerily homeward, he knows not, nor ever will know, in this world at least, that while he slumbered, all in one brief hour, wealth was all but made over to him by one heirless passer-by, and death all but dealt him by two reckless ruffians. They were interrupted, and left him, and he never was to know of the narrow escape. The moral of the fantasy is, that sleeping or waking, we hear not the airy footsteps of the strange things that almost happen. And the moralist’s query ensues, Does it not argue a superintending Providence, that while viewless and unexpected events thrust themselves continually athwart our path, there should still be regularity enough in mortal life to render foresight even partially available? The moral of “David Swan” is implicitly conveyed in that passage in “Waverley” which relates Colonel Gardiner’s unconscious escape from the raised and pointed weapon of the Highlander, Callum Beg. An incident that appeals to his superstition makes the intending slayer drop his piece; and “Colonel Gardiner,” we read, “unconscious of the danger he had escaped, turned his horse round, and rode slowly back to the front of his regiment.” So with Mrs. Hilyard, in “Salem Chapel,” on the evening of the secret interview upon the chapel steps. A hidden witness there is of that interview, who, however, sees not the gesture of her companion which bodes, and almost involves, a fatal, a murderous issue. “But even Mrs. Hilyard herself never knew how near, how very near, she was at that moment to the unseen world.” Or glance, again, at the Azteca, in Southey’s “Madoc,” gliding like a snake to where Caradoc lay sleeping—all unconscious of peril, as happy, and happily unconscious, David Swan:—
