BUT alas! out was very much like in, for the same enemy, the darkness, was here also. The next moment, however, came a great gladness -- a firefly, which had wandered in from the garden. She saw the tiny spark in the distance. With slow pulsing ebb and throb of light, it came pushing itself through the air, drawing nearer and nearer, with that motion which more resembles swimming than flying, and the light seemed the source of its own motion.

``My lamp! my lamp!'' cried Nycteris. ``It is the shiningness of my lamp, which the cruel darkness drove out. My good lamp has been waiting for me here all the time! It knew I would come after it, and waited to take me with it.''

She followed the firefly, which, like herself, was seeking the way out. If it did not know the way, it was yet light; and, because all light is one, any light may serve to guide to more light. If she was mistaken in thinking it the spirit of her lamp, it was of the same spirit as her lamp and had wings. The gold-green jet-boat, driven by light, went throbbing before her through a long narrow passage. Suddenly it rose higher, and the same moment Nycteris fell upon an ascending stair. She had never seen a stair before, and found going-up a curious sensation. Just as she reached what seemed the top, the firefly ceased to shine, and so disappeared. She was in utter darkness once more. But when we are following the light, even its extinction is a guide. If the firefly had gone on shining, Nycteris would have seen the stair turn and would have gone up to Watho's bedroom; whereas now, feeling straight before her, she came to a latched door, which after a good deal of trying she managed to open -- and stood in a maze of wondering perplexity, awe, and delight. What was it? Was it outside of her, or something taking place in her head? Before her was a very long and very narrow passage, broken up she could not tell how, and spreading out above and on all sides to an infinite height and breadth and distance -- as if space itself were growing out of a trough. It was brighter than her rooms had ever been -- brighter than if six alabaster lamps had been burning in them. There was a quantity of strange streaking and mottling about it, very different from the shapes on her walls. She was in a dream of pleasant perplexity, of delightful bewilderment. She could not tell whether she was upon her feet or drifting about like the firefly, driven by the pulses of an inward bliss. But she knew little as yet of her inheritance. Unconsciously, she took one step forward from the threshold, and the girl who had been from her very birth a troglodyte stood in the ravishing glory of a southern night, lit by a perfect moon -- not the moon of our northern clime, but a moon like silver glowing in a furnace -- a moon one could see to be a globe -- not far off, a mere flat disk on the face of the blue, but hanging down halfway, and looking as if one could see all around it by a mere bending of the neck.

``It is my lamp,'' she said, and stood dumb with parted lips. She looked and felt as if she had been standing there in silent ecstasy from the beginning.

``No, it is not my lamp,'' she said after a while; ``it is the mother of all the lamps.''

And with that she fell on her knees and spread out her hands to the moon. She could not in the least have told what was in her mind, but the action was in reality just a begging of the moon to be what she was -- that precise incredible splendor hung in the far-off roof, that very glory essential to the being of poor girls born and bred in caverns. It was a resurrection -- nay, a birth itself, to Nycteris. What the vast blue sky, studded with tiny sparks like the heads of diamond nails, could be; what the moon, looking so absolutely content with light -- why, she knew less about them than you and I! but the greatest of astronomers might envy the rapture of such a first impression at the age of sixteen. Immeasurably imperfect it was, but false the impression could not be, for she saw with the eyes made for seeing, and saw indeed what many men are too wise to see.

As she knelt, something softly flapped her, embraced her, stroked her, fondled her. She rose to her feet but saw nothing, did not know what it was. It was likest a woman's breath. For she knew nothing of the air even, had never breathed the still, newborn freshness of the world. Her breath had come to her only through long passages and spirals in the rock. Still less did she know of the air alive with motion -- of that thrice-blessed thing, the wind of a summer night. It was like a spiritual wine, filling her whole being with an intoxication of purest joy. To breathe was a perfect existence. It seemed to her the light itself she drew into her lungs. Possessed by the power of the gorgeous night, she seemed at one and the same moment annihilated and glorified.

She was in the open passage or gallery that ran around the top of the garden walls, between the cleft battlements, but she did not once look down to see what lay beneath. Her soul was drawn to the vault above her with its lamp and its endless room. At last she burst into tears, and her heart was relieved, as the night itself is relieved by its lightning and rain.

And now she grew thoughtful. She must hoard this splendor! What a little ignorance her jailers had made of her! Life was a mighty bliss, and they had scraped hers to the bare bone! They must not know that she knew. She must hide her knowledge -- hide it even from her own eyes, keeping it close in her bosom, content to know that she had it, even when she could not brood on its presence, feasting her eyes with its glory. She turned from the vision, therefore, with a sigh of utter bliss, and with soft quiet steps and groping hands stole back into the darkness of the rock. What was darkness or the laziness of Time's feet to one who had seen what she had that night seen? She was lifted above all weariness -- above all wrong.

When Falca entered, she uttered a cry of terror. But Nycteris called to her not to be afraid, and told her how there had come a rumbling and shaking, and the lamp had fallen. Then Falca went and told her mistress, and within an hour a new globe hung in the place of the old one. Nycteris thought it did not look so bright and clear as the former, but she made no lamentation over the change; she was far too rich to heed it. For now, prisoner as she knew herself, her heart was full of glory and gladness; at times she had to hold herself from jumping up, and going dancing and singing about the room. When she slept, instead of dull dreams, she had splendid visions. There were times, it is true, when she became restless, and impatient to look upon her riches, but then she would reason with herself, saying, ``What does it matter if I sit here for ages with my poor pale lamp, when out there a lamp is burning at which ten thousand little lamps are glowing with wonder?''

She never doubted she had looked upon the day and the sun, of which she had read; and always when she read of the day and the sun, she had the night and the moon in her mind; and when she read of the night and the moon, she thought only of the cave and the lamp that hung there.
