Lowering my body from the branch, I swung downward and slid the fifteen or more feet to the causeway, and as I alighted the silence of the great forest was again shattered by a hideous scream just above my head. Looking up quickly, I saw a creature launching itself toward me and just beyond it a snarling face of utter hideousness. I caught but the briefest glimpse of it—just enough to see that it was a face, with eyes and a mouth—then it was withdrawn amidst the foliage.

Perhaps I only sensed that hideous vision subconsciously at the time, for the whole scene was but a flash upon the retina of my eye, and the other beast was in mid-air above me at the instant; but it remained indelibly impressed upon my memory, and I was to recall it upon a later day under circumstances so harrowing that the mind of mortal earth man may scarce conceive them.

As I leaped back to avoid the creature springing upon me, I still clung to one strand of the rope down which I had lowered myself to the causeway. My grasp upon the rope was unconscious and purely mechanical; it was in my hand, and my fist was clenched; and as I leaped away, I dragged the rope with me. A fortuitous circumstance, no doubt, but a most fortunate one.

The creature missed me, alighting on all fours a few feet from me, and there it crouched, apparently slightly bewildered, and, fortunately for me, it did not immediately charge, giving me the opportunity to collect my wits and back slowly away, at the same time mechanically coiling the rope in my right hand. The little, simple things one does in moments of stress or excitement often seem entirely beyond reason and incapable of explanation; but I have thought that they may be dictated by a subconscious mind reacting to the urge of self-preservation. Possibly they are not always well directed and may as often fail to be of service as not, but then it may be possible that subconscious minds are no less fallible than the objective mind, which is wrong far more often than it is right. I cannot but seek for some explanation of the urge that caused me to retain that rope, since, all unknown to me, it was to be the slender thread upon which my life was to hang.

Silence had again descended upon the weird scene. Since the final scream of the hideous creature that had retreated into the foliage after this thing had leaped for me, there had been no sound. The creature that crouched facing me seemed slightly bewildered. I am positive now that it had not been pursuing me, but that it itself had been the object of pursuit by the other beast that had retreated.

In the dim half-light of the Venusan night I saw confronting me a creature that might be conjured only in the half-delirium of some horrid nightmare. It was about as large as a full-grown puma, and stood upon four handlike feet that suggested that it might be almost wholly arboreal. The front legs were much longer than the hind, suggesting, in this respect, the hyena; but here the similarity ceased, for the creature’s furry pelt was striped longitudinally with alternate bands of red and yellow, and its hideous head bore no resemblance to any earthly animal. No external ears were visible, and in the low forehead was a single large, round eye at the end of a thick antenna about four inches long. The jaws were powerful and armed with long, sharp fangs, while from either side of the neck projected a powerful chela. Never have I seen a creature so fearsomely armed for offense as was this nameless beast of another world. With those powerful crablike pincers it could easily have held an opponent far stronger than a man and dragged it to those terrible jaws.

For a time it eyed me with that single, terrifying eye that moved to and fro at the end of its antenna, and all the time its chelae were waving slowly, opening and closing. In that brief moment of delay I looked about me, and the first thing that I discovered was that I stood directly in front of an opening cut in the bole of the tree; an opening about three feet wide and over six feet high. But the most remarkable thing about it was that it was closed by a door; not a solid door, but one suggesting a massive wooden grill.

As I stood contemplating it and wondering what to do, I thought that I saw something moving behind it. Then a voice spoke to me out of the darkness beyond the door. It sounded like a human voice, though it spoke in a language that I could not understand. The tones were peremptory. I could almost imagine that it said, “Who are you, and what do you want here in the middle of the night?”

“I am a stranger,” I said. “I come in peace and friendship.”

Of course I knew that whatever it was behind that door, it could not understand me; but I hoped that my tone would assure it of my peaceful designs. There was a moment’s silence and then I heard other voices. Evidently the situation was being discussed; then I saw that the creature facing me upon the causeway was creeping toward me, and turned my attention from the doorway to the beast.
