He had not drunk cachassa that day and was consequently quite sober; he had not had fever for two weeks and was in good health physically as well as mentally; he had never so much indulged in the dissipations of civilisation that his nerves had been affected; he had lived all his life in these surroundings and knew no fear of man or beast. And now, this splendid type of manhood, free and unbound in his thoughts and unprejudiced by superstition, broke down completely and hid his face in his hands, sobbing like a child in a dark room afraid of ghosts. He had been called to this spot three times without knowing the cause, and now, the mysterious force attracting him, as a magnet does a piece of iron, he was unable to move. Helpless as a child he awaited his fate.

Luckily three workers from headquarters happened to pass on their way to their homes, which lay not far above the "Creek of Hell," and when they heard sobbing from the bank they called out.

The hypnotised seringueiro managed to state that he had three times been forced, by some strange power, to the spot where he now was, unable to get away, and that he was deadly frightened. The rubber-workers, with rifles cocked, approached in their canoe, fully prepared to meet a jaguar, but when only a few yards from their comrade they saw directly under the root where the man was sitting the head of a monstrous boa-constrictor, its eyes fastened on its prey. Though it was only a few feet from him, he had been unable to see it.

One of the men took good aim and fired, crushing the head of the snake, and breaking the spell, but the intended victim was completely played out and had to lie down in the bottom of the canoe, shivering as if with ague.

The others took pains to measure the length of the snake before leaving. It was 79 palmas or 52 feet 8 inches. In circumference it measured 11 palmas, corresponding to a diameter of 28 inches. Its mouth, they said, was two palmas or sixteen inches, but how they mean this to be understood I do not know.

This event happened while I was living at headquarters. I had a long talk with Perreira, but could not shake his statement, nor that of the three others; nevertheless, I remained a sceptic as to this alleged charming or mesmeric power of the snakes, at least so far as man is concerned.

At that time we were awaiting the arrival of the monthly launch from the town of Remate de Males, and had spent a day weighing rubber at the camp of one of the employees, half a day's journey from headquarters. The rubber-pellets were loaded into our large canoe to take up to Floresta. We spent the evening drinking black coffee and eating some large, sweet pineapples, whereafter we all took a nap lasting until midnight, when we got up to start on our night trip. It had been considered best to travel at night, when it was nice and cool with none of the pestering insects to torture us, and we were soon paddling the heavy canoe at a merry rate, smoking our pipes and singing in the still, dark night. Soon we rounded a point where the mighty trees, covered with orchids and other parasitic plants, sent their branches down to the very water which in its depths was hiding the dreaded water-snakes. The only sound we heard was the weird calling of the night-owl, the "Mother of the Moon" as the Indians call it. Except this and the lapping sound of water, as we sped along, nothing disturbed the tranquillity of the night.

I was in the act of lighting another pipe when one of the men cried out:

"What's this?"

We all stopped paddling and stared ahead at a large dark object, resting on a moon-lit sand-bar not far from us. Then someone said, "Sucuruju." Few people can comprehend the feeling that creeps into one's heart when this word is pronounced, under such circumstances, in the far-off forest, in the middle of the night. The word means boa-constrictor, but it meant a lot more at this moment. An indescribable feeling of awe seized me. I knew now that I was to face the awful master of the swamps, the great silent monster of the river, of which so much had been said, and which so few ever meet in its lair.
