I looked above my head, hoping to catch the gleam of stars by which I could direct our course and hold the hurtling thing that bore us true to the centre of the shaft. To have touched the side at the speed we were making would doubtless have resulted in instant death for us all. But not a star showed above--only utter and impenetrable darkness.
Then I glanced below me, and there I saw a rapidly diminishing circle of light--the mouth of the opening above the phosphorescent radiance of Omean. By this I steered, endeavouring to keep the circle of light below me ever perfect.
At best it was but a slender cord that held us from destruction, and I think that I steered that night more by intuition and blind faith than by skill or reason.
We were not long in the shaft, and possibly the very fact of our enormous speed saved us, for evidently we started in the right direction and so quickly were we out again that we had no time to alter our course. Omean lies perhaps two miles below the surface crust of Mars. Our speed must have approximated two hundred miles an hour, for Martian fliers are swift, so that at most we were in the shaft not over forty seconds.
