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.

Now I knew why the Kunas had not followed us beyond the jungle. They were aware of the man-killing lianas and had left us to a worse death than any they could inflict. I was safe from them I felt sure. But was I any better off? Before me was an impassable mountain side. On either hand and in the rear those awful, blood-thirsty, sinister vines and, lurking in the jungles, were the savage Kunas with their fatal poisoned darts and powerful bows. I was beset on every side by deadly peril, for I was without food, I had cast aside my gun and even my revolver in my blind, terror-crazed escape from those ghastly living vines, and to remain where I was meant death by starvation or thirst.

But anything was better than this nightmare-like forest. At the thought I glanced with a shudder at the trees and my blood seemed to freeze in my veins.

The forest was approaching me! I could not believe my eyes. Now I felt I must be mad, and fascinated; hypnotized, I gazed, striving my utmost to clear my brain, to make common sense contradict the evidence of my eyes. But it was no delusion. Ponderously, slowly, but steadily the trees were gliding noiselessly up the slope! Their great gnarled roots were creeping and undulating over the ground while the pendant vines writhed and swayed and darted forth in all directions as if feeling their way. And then I saw what had before escaped me. The things were not lianas as I had thought. They were parts of the trees themselves—huge, lithe, flexible tentacles springing from a thick, fleshy livid-hued crown of branches armed with stupendous thorns and which slowly opened and closed like hungry jaws above the huge trunks.

It was monstrous, uncanny, supernatural. A hundred yards and more of open ground had stretched between me and the forest when I had flung myself down, but now a scant fifty paces remained. In a few brief moments the fearsome things would be upon me. But I was petrified, incapable of moving hand or foot, too terrified and overwhelmed even to cry out.

Nearer and nearer the ghastly things came. I could hear the pounding of my heart. A cold sweat broke out on my body. I shivered as with ague. Then a long, warty, tentacle darted toward me and as the loathsome stinking thing touched my hand the spell was broken. With a wild scream I turned and dashed blindly towards the precipice, seeking only to delay, only to avoid for a time the certain awful death to which I was doomed, for the cliff barred all escape and I could go no farther.
