But a movement of horror and of spontaneous recoil from this dreadful scene naturally carried the whole of that scene, raised and idealised, into my dreams, and very soon into a rolling succession of dreams. The actual scene, as looked down upon from the box of the mail, was transformed into a dream, as tumultuous and changing as a musical fugue. This troubled Dream is circumstantially reported in Section the Third, entitled, "Dream-Fugue upon the Theme of Sudden Death." What I had beheld from my seat upon the mail,--the scenical strife of action and passion, of anguish and fear, as I had there witnessed them moving in ghostly silence; this duel between life and death narrowing itself to a point of such exquisite evanescence as the collision neared,--all these elements of the scene blended, under the law of association, with the previous and permanent features of distinction investing the mail itself, which features at that time lay--1st, in velocity unprecedented; 2dly, in the power and beauty of the horses: 3dly, in the official connection with the government of a great nation; and, 4thly, in the function, almost a consecrated function, of publishing and diffusing through the land the great political events, and especially the great battles during a conflict of unparalleled grandeur. These honorary distinctions are all described circumstantially in the FIRST or introductory section ("The Glory of Motion"). The three first were distinctions maintained at all times; but the fourth and grandest belonged exclusively to the war with Napoleon; and this it was which most naturally introduced Waterloo into the dream. Waterloo, I understood, was the particular feature of the "Dream-Fugue" which my censors were least able to account for. Yet surely Waterloo, which, in common with every other great battle, it had been our special privilege to publish over all the land, most naturally entered the Dream under the license of our privilege. If not--if there be anything amiss--let the Dream be responsible. The Dream is a law to itself; and as well quarrel with a rainbow for showing, or for _not_ showing, a secondary arch. So far as I know, every element in the shifting movements of the Dream derived itself either primarily from the incidents of the actual scene, or from secondary features associated with the mail. For example, the cathedral aisle derived itself from the mimic combination of features which grouped themselves together at the point of approaching collision, namely, an arrow-like section of the road, six hundred yards long, under the solemn lights described, with lofty trees meeting overhead in arches. The guard's horn, again--a humble instrument in itself--was yet glorified as the organ of publication for so many great national events. And the incident of the Dying Trumpeter, who rises from a marble bas-relief, and carries a marble trumpet to his marble lips for the purpose of warning the female infant, was doubtless secretly suggested
