We stood horror-stricken upon the bank of that dark pool--mute, impotent spectators of a tragedy we were powerless to prevent.

Vasco, the Spaniard, stood beside me; and I heard his teeth chattering in his head like castanets. As for Forsyth, before that gruesome spectacle was ended he turned away with a kind of sickening sob, at the same time passing a hand across his eyes, by which I knew that the man was human after all. Bannister--who had soon caught us up--said nothing, but stood rigid at the back of us, his rifle in his hands, ready to fire so soon as an opportunity should offer. As for myself, it was as if I was transfixed in petrified amazement. I was hypnotised by the terror of the thing I saw, and could not look away, but must watch the tragic business to the last.

With a great splash of water, the immense body of the snake arose from out the middle of the pool, the surface of which forthwith became agitated by scores of little waves, forming a series of concentric circles, spreading outward to the bank.

We saw the glistening coils of the terrific reptile wind themselves, swiftly and yet stealthily, around the frail body of the doomed, unhappy Amos. He let out a piercing shriek, far more terrifying to hear than the uncanny laughter with which he had disturbed the silence of the woods--it was freezing in its shrillness. And at the same time he threw both his arms above his head, so that his heavy bundle of golden ingots fell into the water and at once disappeared from view.

He made--so far as we could see--no effort of resistance. Terror, it seemed, had mastered every muscle, nerve, and sinew in his body. He was paralysed by fear. We could see, in that dim, religious light, the huge head of the snake swaying backward and forward in front of him, whilst its long forked tongue darted swiftly in and out. We saw the man's face, too, livid with fright, and his wide, staring eyes. For a moment all his features worked spasmodically. I think he tried to cry out once more; but the breath had already been driven from his slender frame by the colossal strength of the relentless serpent that, even as we looked, broke down the slender bulwark of his ribs.

It was then that John Bannister fired. He told me afterwards that he meant to put Baverstock out of the torture he was suffering both of body and of mind. If that were so, it was a lucky shot; for it killed at once the reptile and the man.

The bullet drilled the anaconda, breaking its spine, and thence pierced the heart of Amos Baverstock. The unhappy wretch vanished from sight upon the instant beneath the water of the pool; but the dying struggles of that gigantic snake were amazing to behold.

It lashed right and left, twisting all ways, writhing like a worm; so that we, who looked on, were drenched in flying water. It made the most frantic efforts to drag itself from the pool. The lower part of its body seemed to be paralysed and quite useless; but at last it succeeded in half twining itself around the trunk of a tree, where its head swayed from side to side quite aimlessly. What surprised--and I think horrified--us most of all was the silence of the brute.

I fired, and missed; for my hand trembled violently. And, thereby, it was left to Bannister to end the work he had begun. With his second shot he smashed in the reptile's head; and the great snake at last lay motionless, as loathsome in death as it had been terrible in life. I am ready to believe that five minutes elapsed before any one of us spake or even moved.

"I shall never cease to dream of this," said Forsyth, in a weak voice, at last. "No such nightmare ever was!"
