In an hour we came fairly down into that bright and lovely valley, where was the sweet sound of birds calling to each other, and the glad sight of these live creatures flying through the air. As for the sheep that Rayburn had killed, he was knocked pretty well into a jelly by his half-mile or so of tumble down the mountain-side. But we were not disposed to be over-fastidious, and we quickly had his ribs roasting over a brisk fire: that yet was not so brisk as was our hunger, for we began to eat before the meat was much more than warmed through. When our ravening appetite was appeased a little, Young got out the coffee-pot and set to making coffee. And then, with meat well cooked and coffee in abundance, we made such a meal as can be made only by half-starved men who suddenly have come forth from the dark shadows of threatening death into the glad sunshine of safety. Of what further perils might be in store for us we neither cared nor thought. Our one strong feeling was the purely animal joy bred of deliverance from gloom and danger, and the packing of our bellies with hearty food.
When, at last, our huge meal was ended, we settled back upon our blankets, and fell to smoking. Presently Rayburn gave a prodigious yawn and laid aside his pipe. "I think I'll take a nap," he said. I saw that Young already was nodding and that Pablo had sunk down into slumber; while El Sabio, who had come even closer to starving than we had come, most thankfully rummaged among the rich grass. My eyes were heavy, and I stretched myself out on my blankets, with the warm sunshine comforting my stiffened body, and presently sunk softly into delicious sleep.
I partly woke a few minutes later, as Fray Antonio rose, thinking that we all were lost in slumber, and walked a little apart from us. He alone had made a meal in reasonable moderation, and I saw now that he had gone aside to pray. For a moment the thought stirred in me that I would join him in what I knew was his thanksgiving for our deliverance; but sleep had too strong a hold upon me, and my body slowly fell back upon the blankets and my eyes slowly closed, carrying into my slumber the sight on which they last had rested: the monk kneeling upon the grass beside a great gray rock, with clasped hands and face turned upward, pouring his soul out in grateful prayer.
It was well on in the afternoon when we all woke again; and Young's first remark was that it must be about supper-time. Rayburn fell in with this notion promptly, and so did I myself—rather to my astonishment, for it seemed unreasonable that after such a stuffing I should desire to eat so soon again. But we did make a supper almost as hearty as our breakfast had been, and in a little while wrapped ourselves in our blankets, with our feet towards the heaped-up fire, and went off once more to sleep, and slept through until sunrise of the following day. In truth, the mental strain, bred of our gloomy surroundings and of the dread of starvation that had possessed us, had taxed our physical strength more severely than our mountain climbing and our lack of nourishment. The great amount of strong food that we ate, and our long slumber, showed nature's demand upon us that our waste of tissue should be made good.
When we woke again on the second morning, we all were fresh and strong and eager to press onward. There was little left of the sheep to carry with us; but Rayburn shot half a dozen birds, some species of duck, as we skirted the lake in our passage across the valley, so there was no fear that we should lack for food. At its western end the valley narrowed into a cañon. There was no choice of paths, for this was the sole outlet, and we were assured that we were on the right path by finding the King's symbol and the pointing arrow carved upon the rook. The cañon descended very rapidly, and by noon we were so far below the level of the Mexican plateau that the air had a tropical warmth in it; and so warm was the night—for all the afternoon we continued to descend—that we had no need for blankets when we settled ourselves for sleep.
Rayburn was of the opinion that we were close upon the Tierra Caliente, the hot lands of the coast; and when we resumed our march in the morning he went on in advance of the rest of us, that he might maintain a cautious outlook. If he were right in his conjecture as to our whereabouts, we might at any moment come upon hostile Indians. It was towards noon that he came softly back to us and bade us lay down our packs and advance silently with him, carrying only our arms. "There's something queer ahead; and I thought that I heard voices," he explained. "But there must be no shooting unless we are shot at. Some of these Indians are friendly, and we don't want to start a row with them if they are willing not to row with us."
The cañon was very narrow at this point, and high above us its walls drew so closely together that the shadows about us were deep. As we rounded a bend in it, the rock closed above our heads in a great arch, so that we were in a sort of natural tunnel; at the far end of which was a bright spot showing that a wide and sunny open space was beyond. But over this opening were bars which cut sharply against the light, as though a gigantic spider had spun there a massive web; and as we drew nearer to this curious barrier we saw beyond it a broad and glorious valley, rich with all manner of luxuriant tropical growth and flooded everywhere with the warm light of the sun.
We approached the strange barrier cautiously, and our wonder at it was increased as we found that it was made of the bright metal of which we had found so many specimens; and still more we wondered as we found that the bars were fastened on the side from which we approached, so that we could remove them easily, while from the side of the valley they presented an impassable barrier. In strong excitement we drew out the metal pins which dropped into slots cut in the rock and so held the bars fast, and in a few minutes we had cleared the way for our advance. Just as we were making ready to pass through the opening we heard the sound of voices; and as we quickly drew back into the shadows two men sprang up suddenly before us, and cried in wonder as they saw that the lower bars across the opening were gone. Yet the expression upon their faces was not that of anger; rather did they seem to be stirred by a strong feeling of joy with which was also awe. Both men were accoutred in the fashion which the pictured records show was usual with the Aztec warriors, and one of them—as was indicated by his head-dress and by the metal corselet that he wore—was a chief; and they challenged us sharply, yet with gladness in their tones, in the Aztec tongue.
So sudden and so ringing was this challenge, and so startling was the uprising of the men before us, that as we sprang back into the shadow we instinctively stood ready with our arms. But Fray Antonio, not having any intent to join in the fight, was cooler than the rest of us, and instantly perceived that fighting was not necessary. Therefore he it was who first spoke to these strangers; and his first word to them was, "Friends!"
Then the watchmen, for such they seemed to be, spoke eagerly together for a moment, and pressed to the opening to look upon us; yet seeing us but dimly because of the dark shadows which surrounded us. Pablo was closest to them, and I marvelled to see how like them he was in look and in air. Him they first caught sight of, and as they saw him they both turned from the opening, and, as though calling to some one at a distance, gave both together a great glad shout. Instantly, at some little distance, the cry was repeated; and so again farther on and yet farther, with ever more voices joining in it; so that it swelled and strengthened into a great roar of rejoicing that seemed to sweep over the whole of the valley before us, and to fill it everywhere with tumultuous sounds of joy.
