What became of them none knew—only that they passed forever out of the sight of man into that grim and mysterious country of the pole.
The distance from the barrier to the pole was no more than a swift flier should cover in a few hours, and so it was assumed that some frightful catastrophe awaited those who reached the “forbidden land,” as it had come to be called by the Martians of the outer world.
Thus it was that I went more slowly as we approached the barrier, for it was my intention to move cautiously by day over the ice-pack that I might discover, before I had run into a trap, if there really lay an inhabited country at the north pole, for there only could I imagine a spot where Matai Shang might feel secure from John Carter, Prince of Helium.
We were flying at a snail’s pace but a few feet above the ground—literally feeling our way along through the darkness, for both moons had set, and the night was black with the clouds that are to be found only at Mars’s two extremities.
Suddenly a towering wall of white rose directly in our path, and though I threw the helm hard over, and reversed our engine, I was too late to avoid collision. With a sickening crash we struck the high looming obstacle three-quarters on.
The flier reeled half over; the engine stopped; as one, the patched buoyancy tanks burst, and we plunged, headforemost, to the ground twenty feet beneath.
Fortunately none of us was injured, and when we had disentangled ourselves from the wreckage, and the lesser moon had burst again from below the horizon, we found that we were at the foot of a mighty ice-barrier, from which outcropped great patches of the granite hills which hold it from encroaching farther toward the south.
What fate! With the journey all but completed to be thus wrecked upon the wrong side of that precipitous and unscalable wall of rock and ice!
I looked at Thuvan Dihn. He but shook his head dejectedly.
The balance of the night we spent shivering in our inadequate sleeping silks and furs upon the snow that lies at the foot of the ice-barrier.
