Read it through once

The road fell sharply down in front of us and went corkscrewing in and out around the crags and precipices, down, down, forever down, suggesting nothing so exactly or so uncomfortably as a crooked toboggan slide with no end to it. Mr. Pugh waved his flag and started, like an arrow from a bow, and before I could get out of the car we were gone too. I had previously had but one sensation like the shock of that departure, and that was the gaspy shock that took my breath away the first time that I was discharged from the summit of a toboggan slide. But in both instances the sensation was pleasurable—intensely so; it was a sudden and immense exaltation, a mixed ecstasy of deadly fright and unimaginable joy. I believe that this combination makes the perfection of human delight.
