Naro and I strapped on our packs, picked up our weapons, and opened the door. The three of us stepped out to face the perils of another world. What they might be, we did not know. I had no idea, even, what part of the country was inhabited by the _Krimlu_. But Austen had not let himself be conquered by the mere strangeness of the place. I still hoped to be able to find him, although a search in such a jungle as that about us seemed hopeless. The walls of the rocket-ship were still glowing dully red with the heat of its passage through the air, and we hurried away over the gravel for fifty yards, to get beyond the fierce heat it radiated. The patch of sky above was a dull, dusky, luminescent purple. It seemed almost as if the mist shut out the daylight and lit the valley with a weird radiance of its own. All about us towered the forest. As the light grew better, we could see that the trees were red. They bore the same feathery fronds, the same star-like flowers of brilliant white, and the same golden-brown fruits as the plants of the plain about Astran. But they were immensely greater; they towered up hundreds of feet. It was like a forest of the tree-ferns of the Carboniferous period, save for the deep bloody scarlet of the leaves. In fact, I think the red plants are descended from some of them, strangely developed by the unusual climatic conditions of the crater, or by the purple mist. The ground all about the gravelly knoll was low and marshy, and the air was heavy with the odors of rotting vegetation. There was no wind; and the air, under the great atmospheric pressure, was heavy, moist and hot. It was oppressive. It hung like a weight upon our chests. And the crimson jungle seemed to possess a terrible life and spirit of its own. It did not belong to our world. The undergrowth was very thick. The higher branches were dimmed by the purple mist. They seemed almost to reach the heavy, dull purple sky. It appeared useless to try to penetrate it. It was an evil being waiting to seize us the moment we crossed its bounds. I got out my compass, and we decided to try to make our way toward the north, in the direction of the pass by which we supposed Austen to have rounded the Silver Lake. As I had last noted our position above the mist, with reference to the lake and the crater walls, we had been about fifteen miles south of the pass, at an estimate. I hoped, by taking a course in that direction, to come across some trace of Austen. As we approached the north side of the clearing, I made a startling discovery.
