Then, just as I felt that the end must be at hand —just as I had decided to turn and sell my life dearly—the forest thinned. Before us sunlight appeared and the next moment we dashed from the jungle into a space free from underbrush but covered with enormous trees draped with gnarled and twisted lianas. The land here rose sharply and, glancing ahead between the trees, I saw the indistinct outlines of a lofty mountain against the sky. Toiling up the slope, breathing heavily, utterly exhausted, I kept on. Then, as a loud shout sounded from the rear, I turned to see five hideously painted Kunas break from the jungle. But they did not follow. To my utter amazement they halted, gave a quick glance about, and, with a chorus of frightened yells, turned and dashed back into the shelter of the jungle. But I had scant time to give heed to this. The Kunas’ cries were still ringing in my ears when a scream from Carlos drew my attention. Thinking him attacked by savages I rushed towards him, drawing my revolver as I ran. With bulging, rolling eyes, blanched face and ghastly, terror stricken features he was struggling, fighting madly, with a writhing, coiling gray object which I took for a gigantic snake. Already his body and legs were bound and helpless in the coils. With his machete he was raining blows upon the quivering awful thing which slowly, menacingly wavered back and forth before him, striving to throw another coil about his body. And then, as I drew near, my senses reeled, I felt that I was in some awful nightmare. The object, so surely, relentlessly, silently encircling and crushing him was no serpent but a huge liana drooping from the lofty branches of a great tree! It seemed absolutely incredible, impossible, unbelieveable. But even as I gazed, transfixed with horror, paralyzed by the sight, the vine threw its last coil about the dying man and before my eyes drew the quivering body into the trees above. Then something touched my leg. With a wild yell of terror I leaped aside. A second vine was writhing and twisting over the ground towards me! Crazed with unspeakable fear I struck at the thing with my machete. At the blow the vine drew sharply back while from the gash a thick, yellowish, stinking juice oozed forth. Turning, I started to rush from the accursed spot but as I passed the first tree another liana writhed forward in my path. Utterly bereft of my senses, slashing madly as I ran, yelling like a madman, I dodged from tree to tree, seeking the open spaces, evading by a hair’s breadth the fearful, menacing, serpent-like vines, until half-crazy, torn, panting and utterly spent I dashed forth into a clear grassy space. Before me, rising like a sheer wall against the sky was a huge precipitous cliff of red rock.
