At the base of the span one of the elfin shells was waiting.
Beyond, scores had gathered, their occupants evidently discussing us in much excitement.

The green dwarf waved us to the piles of cushions and then threw himself beside us.

The vehicle started off smoothly, the now silent throng making way, and swept down the green roadway at a terrific pace and wholly without vibration, toward the seven-terraced tower.
As we flew along I tried to discover the source of the power, but I could not--then.

There was no sign of mechanism, but that the shell responded to some form of energy was certain--the driver grasping a small lever which seemed to control not only our speed, but our direction.
We turned abruptly and swept up a runway through one of the gardens, and stopped softly before a pillared pavilion.

I saw now that these were much larger than I had thought.
