"There is no use," said Vaiti. "It is plain to me that all the tribe know, and they trust to the dangers of the place, whatever these may be. This island is at the very end of the world, it is true, and strange things may happen here."
"Yes, there is nothing that one might not believe in this place," said Pita, looking back. Already the gloom of Hades itself was winding about them, and the air struck gravelike and cold. In the distance the mouth of the cave cast a brief glow of emerald light upon the dewy ferns and mosses close to the threshold, so that they shone like the jewelled foliage of some magic forest in a fairy play. Then came the dripping roof, the enormous stalactite buttresses of the cave, dimly edged with light; the oozing floor, and the lifeless dark.
Vaiti spoke not at all, as they walked side by side down dark tunnel after dark tunnel, across empty, thunderous-echoing black halls and archways—their little candles flitting like fireflies through a dim world of unconquerable gloom. Pita, however, was strangely gay. He yelled aloud to set the echoes booming in the black domes above, when they crossed some invisible great goblin market-place, full of hollow sounds and half-glimpsed monstrosities. He sang when the way along the endless corridors grew tedious, and the glistening stalactite candelabra succeeded one another, thick as forest branches, for mile after mile unchanged. When the path was barred by inky lakes of unknown depth and ghastly chill, and the two explorers had to tie their lights on their heads and swim for it, he pretended to cry at the cold, and played tricks on Vaiti by slipping behind her and catching her feet in his teeth. So they went on, one in wild spirits, the other silent and grave. And the hours of the sunny day slipped by dark and changeless, as they passed farther and farther away life and light into the cold black depths of the cave.
When it was about noon, as near as they could guess, Vaiti took the biscuits and tinned meat out of the sack, and they ate, squatting on the wet floor of the tunnel. They knew that the journey was a long one, and that the way could not well be missed, yet they were beginning to feel a little uneasy now. Did this cave go on for ever?
Somehow, the food did not cheer them and when they rose and went on again they did not talk. And now a worse difficulty than any they had yet encountered suddenly barred the way. The winding tunnel along which they were walking turned sharp round a corner, and then ended to all appearance in nothing. They stood at the edge of an empty gulf, black as a starless sky and of depth unknowable. Thin trickles of light. from the candles wavered faintly about its edges, and showed that the colossal crack had a farther side, but it was impossible to see what lay beyond, and the depth below cast back the candle rays as an armoured hull throws off a rifle bullet.
Pita detached a lump of rock and threw it over the edge. Vaiti watched him with sombre eyes. "There is no bottom there," she said. "It goes through the earth, and out on the other side; that is what I think."
"Children's talk," said Pita, listening intently. There was an echoing rattle as the stone bounded from side to side on its way down. The rattle grew fainter and fainter, diminished to a sound like the ticking of a watch, faded to an almost imperceptible vibration, and then seemed to die out. Seemed—for although there was nothing left for the ear to catch, the sharpened sensory nerves of the body still responded to a faint tingle, somewhere, somehow, long after the actual sound had faded away.
"I told you," said Vaiti. "There is no bottom." Pita did not answer; he was measuring the narrowest part of the gulf with his eye, and estimating the value of the three short steps of a run that were possible before taking off.
"It is not two fathoms wide here," he said, throwing the provision sack across to judge his distance better in the uncertain light. Yet, despite the three steps of a run, there was not an inch to spare when he landed on the other side, with an effort that strained every muscle of his powerful young body.
"Can you jump it?" he called to Vaiti—without any particular anxiety, for the Maori has no nerves, and he knew what the girl could do aloft on the schooner.
