"Then you think there is land here, trees, even men! You really think—the Green Girl?"
"That was just an idea, about the green tan. But there is sure to be land, of some sort, where the lips of this abyss curve up to meet the water above. And there is no reason why there might not be life upon it—highly developed life, at that. Life may be as old in this place as outside, perhaps older, for it has been protected from the cataclysms of one kind and another that may have swept life off the surface again and again through the ages. And we know there is some kind of intelligence here—"
"No wonder they were willing to freeze the earth! They couldn't tell the difference if the sea were frozen a mile thick!"
Still we held our course to the northward. Presently Sam went back below again. An hour later the horizon was broken by a line of dull blue in the north. A thin blue strip appeared between black sea and scarlet sky, and widened slowly. In another hour I could make out a wall of towering blue cliffs all across the north, rising from the sea as if to support the red sky. They were veiled in the mists of infinite distances. When Sam had made his observations, computed his angles and completed his calculations, he announced that they were a hundred miles north of us, and met the red sky at a level four miles above us as we floated along!
That meant that we were nine miles below the level of the Pacific, according to Sam's figures. The seat of the menace we thought to conquer was a mile below us yet!
As the hours went by, and we still went northward at our crawling pace (we went slowly because Sam thought that the use of the engines at full power would create an etheric disturbance that would reveal our position to our mysterious enemy). The jagged rim of the abyss rose steadily out of the sea. The cliffs, when I focused my powerful glasses upon them, seemed composed of sheer columns of blue rock, reaching up to meet the red roof of waters like gigantic prisms of blue basalt.
At last my searching eyes glimpsed a patch of green below the blue. A vast slope of green hills drew up out of the red-black sea. They gleamed with the pure verdant emerald of well-watered grasslands. Here and there they were marked with huge, strange splotches of purple. I was ever amazed anew at the vastness of the weird world about us.
Steadily the green and purple slopes lifted themselves out of the dark sea before us, and stretched up, through vast plains and low hills, to the sheer wall of rough blue cliffs that lay all about the north, cut off so sharply at the top by the red sky.
At last we came in view of the shore—fringed with a jungle of green and lofty forest. Huge those strange plants were, with long thick leaves, grotesque forms, and fantastic flaming blossoms! I stared at them through the binoculars. They were like nothing that is or has ever been above the sea—like nothing that I had ever seen or imagined! They were strange wild trees of another earth! Their green was weirdly tinted with purple, or with queer metallic tints of silver and bronze! Their incredibly great blooms were prolifically borne and infinitely varied, making the weird jungle an alien fairyland of bright and multicolored flame!
A fit habitat, indeed, for the monstrous things we found there!
