Keeping himself carefully under the overshadowing edge of the rock-bank, and holding his double-bladed knife ready in one hand, Otter swam to the mouth of the Snake’s den. As he approached it he perceived by the great upward force of the water that the real body of the stream entered the pool from below, the hole where the crocodile lived being but a supplementary exit, which doubtless the river followed in times of flood.

Otter reached the mouth of the tunnel without any great difficulty, and, watching his chance, he lifted himself on his hands and slipped through it quickly, for he did not desire to be seen by those who were gathered above. Nor indeed was he seen, for his red head-dress and the goat-skin cloak had been washed away or cast off in the pool, and in that light his black body made little show against the black rock beneath.

Now he was inside the hole, and found himself crouching upon a bed of sand, or rather disintegrated rock, brought down by the waters. The gloom of the place was great, but the light of the white dawn, which had turned to red, was gathering swiftly on the surface of the pool without as the mist melted, and thence was reflected into the tunnel. So it came about that very soon Otter, who had the gift, not uncommon among savages, of seeing in anything short of absolute darkness, was able to make out his surroundings with tolerable accuracy. The place in a corner of which he squatted was a cave of no great height or width, hollowed in the solid rock by the force of water, as smoothly as though it had been hewn by the hand of man: in short, an enormous natural drain-pipe, but constructed of stone instead of earthenware.

In the bottom of this drain trickled a stream of water nowhere more than six inches in depth, on either side of which, for ten feet or more, lay a thick bed of debris ground small. How far the cave stretched of course he could not see, nor as yet could he discover the whereabouts of its hideous occupant, though traces of its presence were plentiful, for the sandy floor was marked with its huge footprints, and the air reeked with an abominable stink.

“Where has this evil spirit gone to?” thought Otter; “he must be near, and yet I can see nothing of him. Perhaps he lives further up the cave”; and he crept a pace or two forward and again peered into the gloom.

Now he perceived what had hitherto escaped him, namely, that some eight yards from the mouth of the tunnel a table-shaped fragment of stone rose from its floor to within six feet of the roof, having on the hither side a sloping plane that connected its summit with the stream-bed beneath. Doubtless this fragment or boulder, being of some harder material than the surrounding rock, had resisted the wear of the rushing river; the top of it, as was shown by the high-water marks on the sides of the cave, being above the level of the torrent, which, although it was now represented only by a rivulet, evidently at certain seasons of the year poured down with great force and volume.

“Here is a bed on which a crocodile might sleep,” reflected Otter, creeping a little further forward and staring at the mass of rock, and more especially at a triangular-shaped object that was poised on the top of the sloping plane, and on something which lay beneath it.

“Now, if that thing be another stone,” thought Otter again, “how comes it that it does not slip into the water as it should do, and what is that upon which it rests?” and he took a step to one side to prevent his body from intercepting any portion of the ray of light that momentarily shone clearer and pierced the darkness of the cave to a greater distance.

Then he looked again and almost fell in his horror, for now he could see all. The thing that he had taken for a stone set upon the rock-table was the head of the Dweller in the Waters, for there in it, as the light struck on them, two dreadful eyes gleamed with a dull and changing fire. Moreover, he discovered what was the object which lay under the throat of the reptile. It was the body of that priest whom Otter had taken with him in his leap from the statue, for he could see the dead face projecting on one side.

“Perhaps if I wait awhile he will begin to eat him,” reflected the dwarf, remembering the habits of crocodiles, “and then I can attack him when he rests and sleeps afterwards”; and, acting on this idea, he stood still, watching the green fire as it throbbed and quivered, waxed and waned in the monster’s eyes.

How long he remained thus Otter never knew; but after a time he became conscious that these eyes had taken hold of him and were drawing him towards them, though whether the reptile saw him or not he could not tell. For a space he struggled against this unholy fascination; then, overcome by dread, he strove to fly, back to the pool or anywhere out of reach of those devilish orbs. Alas! it was too late: no step could he move backwards, no, not to save his life.

Now he must go on. It was as though the Water Dweller had read his mind, and drew its foe towards itself to put the matter to the test. Otter took one step forward — rather would he have sprung again off the head of the colossus — and the eyes glowed more dreadfully than ever, as though in triumph.

Then in despair he sank to the ground, hiding his face in his hands and groaning in his heart.

“This is a devil that I have come to fight, a devil with magic in his eyes,” he thought. “And how can I, who am but a common Knobnose dwarf, do battle against the king of evil spirits, clothed in the shape of a crocodile?”

Even now, when he could not see them, he felt the eyes drawing him. Yet, as they were no longer visible, his courage and power of mind came back to him sufficiently to enable him to think again.

“Otter,” he said to himself, “if you stay thus, soon the magic will do its work. Your sense will leave you, and that devil will eat you up as a cobra devours a meer-cat. Yes, he will swallow you, and his inside will be your grave, and that is no end for one who has been called a god! Men, let alone gods, should die fighting, whether it be with other men, with wild beasts, with snakes, or with devils. Think now, if your master, the Deliverer, saw you crouch thus like a toad before an adder, how he would laugh and say, ‘Ho! I thought this man brave. Ho! he talked very loud about fighting the Water Dweller, he who came of a line of warriors; but now I laugh at him, for I see that he is but a cross-bred cur and a coward.’

“Yes, yes, you can hear his words, Otter. Say now, will you bear their shame and sit here until you are snapped up and swallowed?”

Thus the dwarf addressed himself, and it seemed to his bewildered brain that the words which he had imagined were true, and that Leonard really stood by and mocked him.

At last he sprang to his feet, and crying, “Never, Baas!” so loudly that the cave rang with the echoes of his shout, he rushed straight at the foe, holding the two-bladed knife in his right hand.

The crocodile, that was waiting for him to fall insensible, as had ever been the custom of the living victims on whom it fixed its baneful glare, heard his cry and awoke from its seeming torpor. It lifted its head, fire seemed to flash from its dull eyes, its vast length began to stir. Higher and higher it reared its head, then of a sudden it leaped from the slope of rock, as alligators when disturbed leap from a river bank into the water, coming so heavily to the ground that the shock caused the cave to tremble, and stood before the dwarf with its tail arched upwards over its back.

Again Otter shouted, half in rage and half in terror, and the sound seemed to make the brute more furious.

It opened its huge mouth as though to seize him and waddled a few paces forward, halting within six feet of him. Now the dwarf’s chance had come and he knew it, for with the opportunity all his courage and skill returned to him. It was he who sprang and not the crocodile. He sprang, he thrust his arm and the double knife far into the yawning mouth, and for a second held it there, one end pointing upwards to the brain and one to the tongue beneath. He felt the jaws close, but their rows of yellow fangs never touched his arm, for there was that between them which held them some little space apart. Then he cast himself on one side and to the ground, leaving the weapon in the reptile’s throat.

For a few moments it shook its horrible head, while Otter watched gasping, for the reek of the brute’s breath almost overpowered him. Twice it opened its great jaws and spat, and twice it strove to close them. Oh! what if it should rid itself of the knife, or drive it through the soft flesh of the throat? Then he was lost indeed! But this it might not do, for the lower blade caught upon the jawbone, and at each effort it drove the sharp point of the upper knife deeper towards its brain. Moreover, so good was the steel, and so firm were the hide bindings of the handles, shrunken as they were with the wet, that nothing broke or gave.

“Now he will trample me or dash me to pieces with his tail,” said Otter; but as yet the Snake had no such mind — indeed, in its agony it seemed to have forgotten the presence of its foe. It writhed upon the floor of the cave, lashing the rock with its tail, and gasping horribly the while. Then suddenly it started forward past him, and the tough hide rope about Otter’s middle ran out like the line from the bow of a whale-boat when the harpoon has gone home in the quar............
