"Well, you have trained all of us to use the rifles."

He smiled gravely at her understanding.

"Yes, I have. And your skill, and that of the others, with the rifles, will always help us. Yet even so--"

Closer still she drew now, and there was sadness in her eyes.

"I think I see," she said in a voice which choked. "When do you think he will make a move to start trouble?"

Kirby hesitated, then drew a long breath.

"To-day!"

"On--on the day of our union?" Naida echoed in dismay. "Can you tell where or how he will strike at us?"

Kirby shook his head.

"There are a hundred things he could do. Naida, I--I--Well, somehow I am afraid of the ceremony this afternoon--the wedding ceremony!"

He felt a little shiver go through her, and would have taken her in his arms, save that a gay cry rang in the garden then.

"Naida, Naida!" It was her cousin, Nini, a bronze-haired youngster as elfin and Pucklike as her name. "I thought we should never find you! Do you realize this is your _wedding_ day, and that you're acting as if there was nothing to be done?"

Nini darted a mocking glance at Kirby, who grinned.

"Do come, Naida!" cried another girl. "Your gown is ready, and we want you to ourselves for awhile."

Other girls joined them, some singing and some carrying an obligato on the sweet, flutelike instruments which Kirby had first heard as he hung in the throat of the geyser. In front of them all, Kirby laughed and kissed Naida on the forehead. But as he took leave of her thus, he whispered:

"We must not let our guard relax for a second this afternoon. And I think there is a more definite precaution which I will take, besides."

CHAPTER IX

Some hours later, Kirby smiled with tight-lipped satisfaction at thought of that precaution which he had taken. What it was only he, Nini, Ivana, and three other girls knew, which secrecy pleased him as much as the precautionary measure itself.

Seated alone in a dimly-lighted, thick-walled cell of the ancient temple in which the dual ceremony of wedding and coronation would take place, he was waiting for the moment when the festivities would begin. Thus far the Duca had done nothing. Yet Kirby's uneasiness would not leave him, and he continued to be thankful that, if trouble should start, the Duca might not find as many trumps in his hand as he expected.

A couple of hours after Kirby had left Naida and the other girls in the garden, all had begun the two-mile journey from the castle to the small plateau on which stood this temple, where the ceremony would be held.

Now, while Kirby waited alone, the Duca and his caciques had gone to another wing of the temple. Naida, attended by her bridesmaids, had been a.s.signed to a cell of their own, and the rest of the girls were waiting in the nave of the temple. Unable to attend the walk from their plateau to this, the old people of the race had remained in their crystal houses.

With ten minutes more to wait, Kirby rose from a bench on which he had been seated, and began to pace his cell. It was this archaic pile of stone, he finally decided, which was causing his depression. Unlike the bright and cheerful castle, this place, older than any other building in the realm, was squat, thick-walled, and gloomy. Here, in the dusky cells which lined labyrinthine corridors, the early generations of the race had found protection from outside dangers. All of which was all right, Kirby thought, but just the same he wished he had insisted upon being wedded in the brilliant and cheerful amphitheatre.

But presently he stopped pacing and faced the door of his cell. Then he breathed a sigh of relief.

From down the twisting corridors which wound out to the central nave, stole the high sweetness of soprano voices, the whisper of flutes, and the mellow resonance of little gongs of jade and gold. It was the signal for which he had waited.

It had been the Duca's instructions that he should come out into the temple when the music began, and meet Naida there. Both would advance to the altar, and when they were in place, the Duca would come to them.

Kirby, therefore, after a glance at the blue trousers and tunic of tanager scarlet which the girls had made for him, opened the door of his cell, and stepped out.

In a moment he traversed the windings of the corridor, and halted under a flat arch at one side of the temple nave.

As he paused so, to await the appearance of Naida and her bridesmaids under a similar arch directly across the temple, he held his breath. Not even nymphs could be as graceful as were the twenty-six girls who were performing the dance of Life Immortal, which tradition decreed should be given before the ceremony by which, in this realm, two souls were wedded. The flash of rainbow gowns was like the swirling of light in a sky at dawning. The music of voices, flutes, and the little gongs of jade, would have stirred the souls of the dead.

If only the confounded sense of approaching disaster would leave him, Kirby thought grimly, this would be a magnificent moment. As it was, he turned his eyes away from the girls, and began to examine the temple.

Just as Naida had told him the case would be, he found both sides of the nave surrounded by arches similar to the one under which he was standing. Everywhere, dim and tortuous corridors led to cells like the one he had just left. Then, in one end of the nave, loomed a closed door from behind which the Duca and caciques would appear when the couple to be wedded were in place, before the altar.

The altar itself, a rectangular ma.s.s of some jadelike stone, stood at a distance of perhaps twenty paces in front of the closed door. On top of the greenish stones, resting on a cushion of some crimson material, flashed the crown which would be used at the coronation. Kirby's eyes widened as he beheld a single rose-cut diamond two inches in diameter, mounted in an exquisitely simple bandeau of wrought gold. But, a moment later, even the crown which would be his--if nothing happened--seemed only a bauble compared to the other prize which he had won in this world beneath the world.

Naida!

He realized that the dance was ended, the music stilled, and that the rainbow garbed girls had formed a double line in the center of the temple. Suddenly his heart beat fast, and for just a moment, as he dared look full and deeply at Naida, and she smiled back at him across the distance, he even forgot to be depressed.

But even as he advanced to meet her, his uneasiness returned.

Now the girls were singing again, their voices raised in a triumphant chorale as beautiful as Naida's face with its warm red lips and smiling eyes, as beautiful as her wedding gown that might have been woven, in its filminess, of mist from the sea. The bridesmaids, silent, their lovely faces alight, paused. But Naida came on.

From her floated to Kirby a fragrance more overwhelming than even the perfume of the geyser. Presently he felt her hand on his arm, and at last they stood side by side. Now again, his premonition of evil left him for a flash; but again it returned.

"I love you," he whispered.

"I love _you_."

"But I am still afraid."

Naida's smile faded.

"And I too. Oh, I've been terribly afraid! We will keep our guard!"

"Yes."

In front of them, on the altar, the crown diamond winked and shimmered in a dim light. The swelling chorus of triumph, in which the bridesmaids had joined now, made the whole temple ring. Slowly, while Naida moved easily beside him, Kirby began to march to the altar.

Then it was done, and they were halted. After both of them had given a lingering glance at the crown whose diamond shimmered now within their reach, they raised their eyes to the closed door behind the altar.

The thing was swinging open. An inch it moved, two inches.

Kirby waited, never taking his eyes away from the widening crack. With a crashing final volume of sound, the chorus swept magnificently to its climax. Then the door was flung wide.
