‘Oh, let’s get out,’ whispered Suzanne.

And from the darkness came the startled whisper: ‘Get out! Get out!’

Caught in a nameless terror, the girls fled down the dark passage, panting for the sunlight, which they could see glimmering in the distance through the bars. As they ran their courage mounted until they threw themselves breathless and laughing against the gate. It held fast! They jerked. It was locked! Panic-stricken, they gazed at one another. Then they began to shake the gate and to scream frantically for help. There was no answer. The gate had been built to keep people out of the dangerous cave. It reached to the roof, and someone had locked it while the girls had been exploring.

‘Let’s go back to the end of the passage, where it is dry,’ said Treska sensibly. ‘There may be a party of people in the cave now, and if there is they must come out this way. Or others will come this afternoon.’

Treska tried hard to believe what she said, but how could she tell whether anyone would come that day or indeed for many days?

‘Of course those were only echoes back there, weren’t they?’ asked Masha fearfully.

‘Of course,’ said Treska.

At the end of the passage all huddled together to keep warm. In one direction they could look toward the patch of light; in the other, into the fathomless blackness of the cave. As their eyes grew used to the darkness, they could dimly make out the walls nearest them, all of white rock, clean and dry as if freshly cut.

Suddenly a sound deep in the cave caught their attention, and then a faint glow appeared, like a little cloud at a great distance. As it rapidly increased, the girls realized that a procession of people carrying lighted tapers was approaching. They came slowly along a ledge of rock so high above the girls that it seemed like an upper floor of the cave. The flickering candles lighted up glistening walls, sparkling pendants of rock and strange forms, which struggled out of the shadow; but the height of the cave was so vast that the top still hung in darkness. Was the whole mountain hollow, then, like a melon? The procession wound slowly down a slippery staircase of wood, the guide leading the way with a big torch.

Even Masha knew that it was a party of everyday people, wrapped in warm coats and furs, who had been visiting the far interior of the cave. As they came forward, holding their lighted tapers high, more and more of the wonders of the cave were revealed; gleaming columns, low-hanging arches and lofty vaulting grew out of the darkness like parts of a fairy palace.
