This exhortation seemed to have some effect. The man stirred slightly, and emitted a sigh. Presently he muttered, "I can--lick him--yet!"

"He will live, princess," remarked Kamaiakan. "But where is the treasure?"

"My treasure is here!" was her reply; and again she bent to kiss the half-conscious man, who knew not of his good fortune. After an interval she added, "It is in the hollow beneath that archway. Go down three paces: on the wall at the left you will feel a ring. Pull it outwards, and the stone will give way. Behind it lies the chest in which the jewels are. But remember your promise!"

Kamaiakan peered into the hollow, shook his head as one who loves not his errand, and stepped in. The black shadow swallowed him up. Semitzin paid no further attention to him, but was absorbed in ministering to her patient, whose strength was every moment being augmented, though he was not yet aware of his position. But all at once a choking sound came from within the cave, and in a few moments Kamaiakan staggered up out of the shadow, and sank down across the threshold of the arch.

"Semitzin," he gasped, in a faint voice, "the curse of the G.o.ds is upon the spot! The air within is poisonous. It withers the limbs and stops the breath. No one may touch the treasure and live. Let us go!"

"The G.o.ds do not love those who fear," replied the princess, contemptuously. "But the treasure is mine, and it may well be that no other hand may touch it. Fold that blanket, and lay it beneath his head.

I will bring the jewels."

"Do not attempt it: it will be death!" exclaimed the old man.

"Shall a princess come to her lover empty-handed? Do you watch beside him while I go. Ah, if your Miriam were here, I would not fear to have him choose between us!"

With these words, Semitzin stepped across the threshold of the crypt, and vanished in its depths. The Indian, still dizzy and faint, knelt on the rock without, bowed down by sinister forebodings.

Several minutes pa.s.sed. "She has perished!" muttered Kamaiakan.

Freeman raised himself on one elbow, and gazed giddily about him. "What the deuce has happened?" he demanded, in a sluggish voice. "Is that you, professor?"

Suddenly, a rending and rushing sound burst from the cave. Following it, Semitzin appeared at the entrance, dragging a heavy metal box, which she grasped by a handle at one end. Immediately in her steps broke forth a great volume of water, boiling up as if from a caldron. It filled the cave, and poured like a cataract into the gorge. The foundations of the great deep seemed to be let loose.

Semitzin lifted from her face the woollen mask, or visor, which she had closed on entering the cave. She was panting from exertion, but neither her physical nor her mental faculties were abated. She spoke sharply and imperiously:

"Bring up the mule, and help me fasten the chest upon him. We must reach higher ground before the waters overtake us. And now----" She turned to Freeman, who by this time was sitting up and regarding her with stupefaction.

"Miriam!" was all he could utter.

She shook her head, and smiled. "I am she who loves you, and whom you will love. I give you life, and fortune, and myself. But come: can you mount and ride?"

"I can't make this out," he said, struggling, with her a.s.sistance, to his feet. "I have read fairy-tales, but this... Kamaiakan, too!"

Semitzin, meanwhile, brought him to the mule, and half mechanically he scrambled into the saddle, the chest being made fast to the crupper.

Semitzin seized the bridle, and started up the gorge, Kamaiakan bringing up the rear. The lower levels were already filling with water, which came pouring out through the archway in a full flood, seemingly inexhaustible.

"I see how it is," mumbled Freeman, half to himself. "The earthquake--I remember! I got hit somehow. They came from the ranch to hunt me up. But where are the general and Professor Meschines? How long ago was it?

And how came Miriam... Could the mirage have had anything to do with it?--Here, let me walk," he called out to her, "and you get up and ride."

She turned her head, smiling again, but hurried on without speaking.

The roar of the torrent followed them. Once or twice the mule came near losing his footing. Freeman, whose head was swimming, and his brains buzzing like a hive of bees, had all he could do to maintain his equilibrium in the saddle. He was excruciatingly thirsty, and the gurgling of waters round about made him wish he might dismount and plunge into them. But he lacked power to form a decided purpose, and permitted the more energetic will to control him. It might have been minutes, or it might have been hours, for all he knew: at last they halted, near the base of the white pyramid.

"Here we are safe," said Semitzin, coming to his side. "Lean on me, my love, and I will lift you down."

"Oh, I'm not quite so bad as that, you know," said Freeman, with a feeble laugh; and, to prove it, he blundered off the saddle, and came down on the ground with a thwack. He picked himself up, however, and recollecting that he had a flask with brandy in it, he felt for it, found it intact, and, with an inarticulate murmur of apology, raised it to his lips. It was like the veritable elixir of life: never in his life before had Freeman quaffed so deep a draught of the fiery spirit. It was just what he wanted.

But he felt oddly embarra.s.sed. He did not know what to make of Miriam.

It was not her strange costume merely, but she seemed to have put on--or put off--something with it that made a difference in her. She was a.s.sertive, imperious; as loving, certainly, as lover could wish, but not in the manner of the Miriam he knew. He might have liked the new Miriam better, had he not previously fallen in love with the former one. He could not make advances to her: he had no opportunity to do so: she was making advances to him!

"My love," she said, standing before him, "I have come back to the world for your sake. Before Semitzin first saw you, her heart was yours. And I come to you, not poor, but with the riches and power of the princes of Tenocht.i.tlan. You shall see them: they are yours!--Kamaiakan, take down the chest."

"What's that about Semitzin?" inquired Freeman. "I'm not aware that I knew any such person."

"Kamaiakan!" repeated the other, raising her voice, and not hearing Freeman's last words. Kamaiakan was nowhere to be seen. Both Freeman and she had supposed that he was following on behind the mule; but he had either dropped behind, or had withdrawn somewhere. "O Kamaiakan!"

shouted Freeman, as loud as he could.

A distant hail, from the direction of the desert, seemed to reply.

"That can't be he," said Freeman. "It was at least a quarter of a mile off, and the wrong direction, too. He's in the gorge, if he's anywhere."

"Hark!" said Semitzin.

They listened, and detected a low murmur, this time from the gorge.

"He's fallen down and hurt himself," said Freeman. "Let's go after him."

In a few moments they stumbled upon the old Indian, reclining with his shoulders against a rock, and gasping heavily.

"My princess," he whispered, as she bent over him, "I am dying. The poisonous air in the cave was fatal to me, though the spell that is upon the Golden Fleece protected you. I have done what the G.o.ds commanded. I am absolved of my vow. The treasure is safe."

"Nonsense! you're all right!" exclaimed Freeman. "Here, take a pull at this flask. It did me all the good in the world!"

But the old man put it aside, with a feeble gesture of the hand. "My time is come,----" said he.--"Semitzin, I have been faithful."

"Semitzin, again!" muttered Freeman. "What does it mean?"

"But what is this?" cried the girl, suddenly starting to her feet. "I feel the sleep coming on me again! I feel Miriam returning! Kamaiakan, have you betrayed me at the last?"

"No, no, princess, I have done nothing," said he, in a voice scarcely audible. "But, with death, the strength of my will goes from me, and I can no longer keep you in this world. The spirit of Miriam claims her rightful body, and you must struggle against her alone. The G.o.ds will not be defied: it is the law!"

His voice sank away into nothing, and his beard drooped upon his breast.

"He's dying, sure enough, poor old chap," said Freeman. "But what is all this about? I never heard anything like this language you two talk together."

Semitzin turned towards him, and her eyes were blazing.

"She shall not have you!" she cried. "I have won you--I have saved you--you are mine! What is Miriam? Can she be to you what I could be?--You shall never have him!" she continued, seeming to address some presence invisible to all eyes but hers. "If I must go, you shall go with me!" She fumbled in her belt, caught the handle of a knife there, and drew it. She lifted it against her heart; but even then there was an uncertainty in her movement, as if her mind were divided against itself, or had failed fully to retain the thread of its purpose. But Freeman, who had pa.s.sed rapidly from one degree of bewilderment to another, was actually relieved to see, at last, something that he could understand.

Miriam--for some reason best known to herself--was about to do herself a mischief. He leaped forward, caught her in his arms, and s.n.a.t.c.hed the knife from her grasp.

For a few moments she struggled like a young tiger. And it was marvellous and appalling to hear two voices come from her, in alternation, or confusedly mingled. One said, "Let me kill her! I will not go! Keep back, you pale-faced girl!" and then a lower, troubled voice, "Do not let her come! Her face is terrible! What are those strange creatures with her? Harvey, where are you?"

At last, with a fierce cry, that died away in a shuddering sigh, the form of flesh and blood, so mysteriously possessed, ceased to struggle, and sank back in Freeman's arms. His own strength was well-nigh at an end. He laid her on the ground, and, sitting beside her, drew her head on his knee. He had been in the land of spirits, contending with unknown powers, and he was faint in mind and body.

Yet he was conscious of the approaching tread of horses' feet, and recollected the hail that had come from the desert. Soon loomed up the shadowy figures of mounted men, and they came so near that he was constrained to call out, "Mind where you're going! You'll be over us!"

"Who are you?" said a voice, which sounded like that of General Trednoke, as they reined up.

"There's Kamaiakan, who's dead; and Miriam Trednoke, who has been out of her mind, but she's got over it now, I guess; and I,--Harvey Freeman."
