"At first I was too much confused to observe anything accurately. The general burst of terrific grandeur was all that I beheld. When I recovered myself a little, however, my gaze fell instinctively downward. In this direction I was able to obtain an unobstructed view from the manner in which the smack hung on the inclined surface of the pool. She was quite upon an even keel--that is to say, her deck lay in a plane parallel with that of the water--but this latter sloped at an angle of more than forty-five degrees, so that we seemed to be lying upon our beam-ends. I could not help observing, nevertheless, that I had scarcely more difficulty in maintaining my hold and footing in this situation than if we had been upon a dead level, and this, I suppose, was owing to the speed at which we revolved. "The rays of the moon seemed to search the very bottom of the profound gulf; but still I could make out nothing distinctly, on account of a thick mist in which everything there was enveloped, and over which there hung a magnificent rainbow, like that narrow and tottering bridge which Mussulmen say is the only pathway between Time and Eternity. This mist or spray was no doubt occasioned by the clashing of the great walls of the funnel as they all met together at the bottom, but the yell that went up to the heavens from out of that mist I dare not attempt to describe. "Our first slide into the abyss itself, from the belt of foam above, had carried us a great distance down the slope, but our farther descent was by no means proportionate. Round and round we swept--not with any uniform movement--but in dizzying swings and jerks, that sent us sometimes only a few hundred yards--sometimes nearly the complete circuit of the whirl. Our progress downward at each revolution was slow but very perceptible.
