The raft was then taken about forty feet along the left bank, but as it moved toward the center of the river the current increased in strength, the ubas were moored, and the rowers kept it from drifting, so as only to allow it to advance with extreme slowness.
Benito descended very gently, and again found himself on the firm sand.
When his heels touched the ground it could be seen, by the length of the haulage cord, that he was at a depth of some sixty-five or seventy feet. He was therefore in a considerable hole, excavated far below the ordinary level.
The liquid medium was more obscure, but the limpidity of these transparent waters still allowed the light to penetrate sufficiently for Benito to distinguish the objects scattered on the bed of the river, and to approach them with some safety. Besides, the sand, sprinkled with mica flakes, seemed to form a sort of reflector, and the very grains could be counted glittering like luminous dust.
Benito moved on, examining and sounding the smallest cavities with his spear. He continued to advance very slowly; the communication cord was paid out, and as the pipes which served for the inlet and outlet of the air were never tightened, the pump was worked under the proper conditions.
Benito turned off so as to reach the middle of the bed of the Amazon, where there was the greatest depression. Sometimes profound obscurity thickened around him, and then he could see nothing, so feeble was the light; but this was a purely pa.s.sing phenomenon, and due to the raft, which, floating above his head, intercepted the solar rays and made the night replace the day. An instant afterward the huge shadow would be dissipated, and the reflection of the sands appear again in full force.
All the time Benito was going deeper. He felt the increase of the pressure with which his body was wrapped by the liquid ma.s.s. His respiration became less easy; the retractibility of his organs no longer worked with as much ease as in the midst of an atmosphere more conveniently adapted for them. And so he found himself under the action of physiological effects to which he was unaccustomed. The rumbling grew louder in his ears, but as his thought was always lucid, as he felt that the action of his brain was quite clear--even a little more so than usual--he delayed giving the signal for return, and continued to go down deeper still.
Suddenly, in the subdued light which surrounded him, his attention was attracted by a confused ma.s.s. It seemed to take the form of a corpse, entangled beneath a clump of aquatic plants. Intense excitement seized him. He stepped toward the ma.s.s; with his spear he felt it. It was the carca.s.s of a huge cayman, already reduced to a skeleton, and which the current of the Rio Negro had swept into the bed of the Amazon. Benito recoiled, and, in spite of the a.s.sertions of the pilot, the thought recurred to him that some living cayman might even then be met with in the deeps near the Bar of Frias!
But he repelled the idea, and continued his progress, so as to reach the bottom of the depression.
And now he had arrived at a depth of from eighty to a hundred feet, and consequently was experiencing a pressure of three atmospheres. If, then, this cavity was also drawn blank, he would have to suspend his researches.
Experience has shown that the extreme limit for such submarine explorations lies between a hundred and twenty and a hundred and thirty feet, and that below this there is great danger, the human organism not only being hindered from performing his functions under such a pressure, but the apparatus failing to keep up a sufficient supply of air with the desirable regularity.
But Benito was resolved to go as far as his mental powers and physical energies would let him. By some strange presentiment he was drawn toward this abyss; it seemed to him as though the corpse was very likely to have rolled to the bottom of the hole, and that Torres, if he had any heavy things about him, such as a belt containing either money or arms, would have sunk to the very lowest point. Of a sudden, in a deep hollow, he saw a body through the gloom! Yes! A corpse, still clothed, stretched out like a man asleep, with his arms folded under his head!
Was that Torres? In the obscurity, then very dense, he found it difficult to see; but it was a human body that lay there, less than ten paces off, and perfectly motionless!
A sharp pang shot through Benito. His heart, for an instant, ceased to beat. He thought he was going to lose consciousness. By a supreme effort he recovered himself. He stepped toward the corpse.
Suddenly a shock as violent as unexpected made his whole frame vibrate!
A long whip seemed to twine round his body, and in spite of the thick diving-dress he felt himself lashed again and again.
"A gymnotus!" he said.
It was the only word that pa.s.sed his lips.
In fact, it was a _"puraque,"_ the name given by the Brazilians to the gymnotus, or electric snake, which had just attacked him.
It is well known that the gymnotus is a kind of eel, with a blackish, slimy skin, furnished along the back and tail with an apparatus composed of plates joined by vertical lamellae, and acted on by nerves of considerable power. This apparatus is endowed with singular electrical properties, and is apt to produce very formidable results. Some of these gymnotuses are about the length of a common snake, others are about ten feet long, while others, which, however, are rare, even reach fifteen or twenty feet, and are from eight to ten inches in diameter.
Gymnotuses are plentiful enough both in the Amazon and its tributaries; and it was one of these living coils, about ten feet long, which, after uncurving itself like a bow, again attacked the diver.
Benito knew what he had to fear from this formidable animal. His clothes were powerless to protect him. The discharges of the gymnotus, at first somewhat weak, become more and more violent, and there would come a time when, exhausted by the shocks, he would be rendered powerless.
Benito, unable to resist the blows, half-dropped upon the sand. His limbs were becoming paralyzed little by little under the electric influences of the gymnotus, which lightly touched his body as it wrapped him in its folds. His arms even he could not lift, and soon his spear escaped him, and his hand had not strength enough left to pull the cord and give the signal.
Benito felt that he was lost. Neither Manoel nor his companions could suspect the horrible combat which was going on beneath them between the formidable puraque and the unhappy diver, who only fought to suffer, without any power of defending himself.
And that at the moment when a body--the body of Torres without a doubt!--had just met his view.
By a supreme instinct of self-preservation Benito uttered a cry. His voice was lost in the metallic sphere from which not a sound could escape!
And now the puraque redoubled its attacks; it gave forth shock after shock, which made Benito writhe on the sand like the sections of a divided worm, and his muscles were wrenched again and again beneath the living lash.
Benito thought that all was over; his eyes grew dim, his limbs began to stiffen.
But before he quite lost his power of sight and reason he became the witness of a phenomenon, unexpected, inexplicable, and marvelous in the extreme.
A deadened roar resounded through the liquid depths. It was like a thunder-clap, the reverberations of which rolled along the river bed, then violently agitated by the electrical discharges of the gymnotus.
Benito felt himself bathed as it were in the dreadful booming which found an echo in the very deepest of the river depths.
And then a last cry escaped him, for fearful was the vision which appeared before his eyes!
The corpse of the drowned man which had been stretched on the sand arose! The undulations of the water lifted up the arms, and they swayed about as if with some peculiar animation. Convulsive throbs made the movement of the corpse still more alarming.
It was indeed the body of Torres. One of the suns rays shot down to it through the liquid ma.s.s, and Benito recognized the bloated, ashy features of the scoundrel who fell by his own hand, and whose last breath had left him beneath the waters.
And while Benito could not make a single movement with his paralyzed limbs, while his heavy shoes kept him down as if he had been nailed to the sand, the corpse straightened itself up, the head swayed to and fro, and disentangling itself from the hole in which it had been kept by a ma.s.s of aquatic weeds, it slowly ascended to the surface of the Amazon.
CHAPTER XI. THE CONTENTS OF THE CASE
WHAT WAS it that had happened? A purely physical phenomenon, of which the following is the explanation.
The gunboat Santa Ana, bound for Manaos, had come up the river and pa.s.sed the bar at Frias. Just before she reached the _embouchure_ of the Rio Negro she hoisted her colors and saluted the Brazilian flag. At the report vibrations were produced along the surface of the stream, and these vibrations making their way down to the bottom of the river, had been sufficient to raise the corpse of Torres, already lightened by the commencement of its decomposition and the distension of its cellular system. The body of the drowned man had in the ordinary course risen to the surface of the water.
This well-known phenomenon explains the reappearance of the corpse, but it must be admitted that the arrival of the Santa Ana was a fortunate coincidence.
By a shout from Manoel, repeated by all his companions, one of the pirogues was immediately steered for the body, while the diver was at the same time hauled up to the raft.
Great was Manoel"s emotion when Benito, drawn on to the platform, was laid there in a state of complete inertia, not a single exterior movement betraying that he still lived.
Was not this a second corpse which the waters of the Amazon had given up?
As quickly as possible the diving-dress was taken off him.
Benito had entirely lost consciousness beneath the violent shocks of the gymnotus.
Manoel, distracted, called to him, breathed into him, and endeavored to recover the heart"s pulsation.
"It beats! It beats!" he exclaimed.
Yes! Benito"s heart did still beat, and in a few minutes Manoel"s efforts restored him to life.
"The body! the Body!"
Such were the first words, the only ones which escaped from Benito"s lips.
"There it is!" answered Fragoso, pointing to a pirogue then coming up to the raft with the corpse.
