vast cavern roof.
It grew darker. The gray outside had changed to purple. In the palace the brilliant electric lights in prismatic globes refused to allow the day to die. He was thinking of returning to the throne-room when a page in silken attire approached from the direction of the king's quarters.
“To your chambers, master,” he announced, bowing respectfully.
Thorndyke arose and followed him to an elevator near by. They ascended to the highest balcony of the great rotunda. Here they alighted and turned to the right, the page leading the way, a key in his hand. Presently the page stopped at a door and unlocked it and preceded the Englishman into the room. As they entered an electric light in a chandelier flashed up automatically.
It was a sumptuous apartment, and adjoining it were several connecting rooms all elegantly furnished. The page crossed the room and opened a door to a little stairway.
“It leads to the roof,” he said. “The princess told me to call your attention to it, that you might go out and view the starlight.”
When the page had retired, Thorndyke, feeling lonely, ascended the stairs to the roof. It was perfectly flat save for the great dome which stood in the centre and the numerous pinnacles and cupolas on every hand, and was very spacious. The Englishman's loneliness increased, for no matter in what direction he looked, there was not a living soul in sight. Far in front of him he saw a stone parapet. He went to this and looked down on the city. The electric lights were vari-colored, and arranged so that when seen from a distance or from a great height they assumed artistic designs that were beautiful to behold.
The regular streets and rows of buildings stretched away till the light in the farthest distance seemed an ocean of blending colors. Overhead the vault was black, and only here and there shone a star; but as he looked upward they began to flash into being, and so rapidly that the sky seemed a vast battlefield of electricity.
“Wonderful! Wonderful!” he ejaculated enthusiastically, when the black dome was filled with twinkling stars. He leaned for a long time against the parapet, listening to the music from the streets below, and watching the flying-machines with their vari-colored lights rise from the little parks at the intersection of the streets and dart away over the roofs like big fireflies. Then he began to feel sleepy, and, going back to his chambers, he retired.
When he awoke the next morning, the rosy glow of the sun was shining in at his windows. On rising he was surprised to find a delectable breakfast spread on a table in his sitting-room.
“Treating me like a lord, any way,” he said drily. “I can't say I dislike the thing as a whole.” When he had satisfied his sharp hunger he went out into a corridor and seeing an elevator he entered it and went down to the throne-room. The king was just leaving his throne, but seeing Thorndyke he turned to him with a smile.
“How did you sleep?” he asked.
“Well, indeed,” replied Thorndyke, with a low bow.
“I cannot talk to you now. I intended to, but I have promised my people a 'War of the Elements' to-day and am busy. You will enjoy it, I trust.”
“I am sure of it, your Majesty.”
“Well, be about the palace, for it is a good point from which to view the display.”
With these words he turned away and the Englishman, as if drawn there by the memory of his last conversation with Bernardino, sought the retreat where he had bidden her good-night. He sat down on the seat they had occupied, and gave himself over to delightful reveries about her beauty and loveliness of nature. Looking up suddenly he saw a pair of white hands part the palm leaves in front of him and the subject of his thoughts emerged into view.
She wore a regal gown and beautiful silken head-dress set with fine gems, and gave him a warm glance of friendly greeting.
“I half hoped to find you here,” she said, blushing modestly under his ardent gaze; “that is, I knew you would not know where to go——” She paused, her face suffused with blushes.
“I did not hope to find you here,” he said, coming to her aid gallantly, “but it was a delight to sit here where I last saw you.”
She blushed even deeper, and a pleased look flashed into her eyes. “It was important that I should see you this morning,” she continued, with a womanly desire to disguise her own feeling. “I wanted to tell you where to meet me when the storm begins.”
“Where?” he asked.
“On the roof of the palace, near the stairs leading down to your chambers. At first it will be very dark, and it is then that we must get out of sight of the palace. No other flying-machines will be in the air, and Captain Tradmos thinks, if we are very careful, we can get away safely before the display of lightning.”
“If we find my friend what can we do with him?”
She hesitated a moment, a look of perplexity on her face, then she said: “We can bring him back and keep him hidden in your chambers till some better arrangement can be made. We shall think of some expedient before long, but at present he must be saved from starvation.”
Thorndyke attempted to draw her to a seat beside him, but she held back. “No,” she said resolutely, “it would never do for us to be seen together. If my father should suspect anything now, all hope would be lost.”
Thorndyke reluctantly released her hand.
“You are right, I beg your pardon,” he said humbly. “I shall meet you promptly. Of course I want to save poor Johnston, but the delight of being with you again, even for a moment, so intoxicates me that I forget even my duty to him.”
After she left him he wandered out in the streets along the busy thoroughfares, and into the beautiful parks, the flowers and foliage changing color as each new hour dawned. The fragrance of the flowers delighted his sense of smell, and the luscious fruits hung from vine and tree in great abundance.
He was impatient for the time to arrive at which he was to meet the princess. After awhile he noticed the people closing the shops and booths, and in holiday dress going to the parks and public squares. He hastened to the palace. The great rotunda and the throne-room were energetically astir. Everybody wore rich apparel and was talking of the coming fete. The king was on his throne surrounded by his men of science. In a cluster of ladies in court dress, the Englishman recognized Bernardino. Catching his eye, she looked startled for an instant, and, then, with a furtive glance at the king, she swept her eyes back to Thorndyke and raised them significantly toward his chambers. He understood, and his quick movement was his reply. He turned immediately to an elevator that was going up, and entered it. Again he was alone on the palace roof. The color of the sunlight looked so natural that he studied it closely to see if he could not detect something artificial in its appearance, but in vain. He found that it did not pain his eyes to look at the sun steadily. He took from his pocket a small sunglass, and focussed the rays on his hand, but the heat was not intensified sufficiently to burn him.
Just then he heard a loud blast of a trumpet in a tall tower to the left of the palace. It seemed a momentous signal. The jostling crowds in the streets below suddenly stood motionless. Every eye was raised to the sky. Not a sound broke the stillness. Following the glances of the crowd a few minutes later, Thorndyke noticed a dark cloud rising in the west, and spreading along the horizon. A feeling of awe came over him as it gradually increased in volume, and, in vast black billows, began to roll up toward the sun.
