Under this steady though rapid anticipation of the evil which _might_ be gathering ahead, ah, reader! what a sullen mystery of fear, what a sigh of woe, seemed to steal upon the air, as again the far-off sound of a wheel was heard! A whisper it was--a whisper from, perhaps, four miles off--secretly announcing a ruin that, being foreseen, was not the less inevitable. What could be done--who was it that could do it--to check the storm-flight of these maniacal horses? What! could I not seize the reins from the grasp of the slumbering coachman? You, reader, think that it would have been in _your_ power to do so. And I quarrel not with your estimate of yourself. But, from the way in which the coachman's hand was viced between his upper and lower thigh, this was impossible. The guard subsequently found it impossible, after this danger had passed. Not the grasp only, but also the position of this Polyphemus, made the attempt impossible. You still think otherwise. See, then, that bronze equestrian statue. The cruel rider has kept the bit in his horse's mouth for two centuries. Unbridle him, for a minute, if you please, and wash his mouth with water. Or stay, reader, unhorse me that marble emperor: knock me those marble feet from those marble stirrups of Charlemagne. The sounds ahead strengthened, and were now too clearly the sounds of wheels. Who and what could it be? Was it industry in a taxed cart?--was it youthful gaiety in a gig? Whoever it was, something must be attempted to warn them. Upon the other party rests the active responsibility, but upon _us_--and, woe is me! that _us_ was my single self--rests the responsibility of warning. Yet, how should this be accomplished? Might I not seize the guard's horn? Already, on the first thought, I was making my way over the roof to the guard's seat. But this, from the foreign mails being piled upon the roof, was a difficult, and even dangerous attempt, to one cramped by nearly three hundred miles of outside travelling. And, fortunately, before I had lost much time in the attempt, our frantic horses swept round an angle of the road, which opened upon us the stage where the collision must be accomplished, the parties that seemed summoned to the trial, and the impossibility of saving them by any communication with the guard.
