As we emerged from the nook in the mountain-side the whole of the valley lay open before us, and never was a more lovely spot beheld by the eyes of man. A half-dozen leagues in front of us rose the great mountain wall which shut in its farther side, and about as far away to the right and to the left these walls swept around in vast curves and joined the cliffs through which we had come by the hollow way that tunnelled beneath them. A noble lake extended nearly the whole length of the valley, and covered near a third of its width, and so seemed less like a lake than like a calm and majestic river. From the water-side the land rose in broad terraces, broken by belts of timber and by many groups of smaller trees, which, because of the regularity of their growth, I took to be fruit plantations. All the open country seemed to be one vast garden, most carefully tended, and everywhere cut up by little canals, whence water for irrigation was drawn. Scattered everywhere about the valley were single houses embowered in trees, and from where we stood we could see also four or five little towns, which also were plentifully shaded. And on the lake many boats were passing, of which several were of a considerable size, and were fitted with curiously shaped sails. And all this exquisite tropical beauty of ample water and luxuriant foliage shone richly beneath the bright splendor of a deep blue tropical sky.

Yet that which most strongly attracted our attention was not this charming display of the manifold excellencies of God's handiwork, but rather a wonderful manifestation of the handiwork of man. Over against us, on the far side of the lake, slantingwise from where we stood, rose a mass of buildings of such vastness and such majestic design that at the first glance we took it to be one of the square-topped mountains which are found not uncommonly in this portion of the world, and around the bases of which are sloping heaps of the fragments of rock which have broken away through countless ages from their weather-worn sides. Yet in a moment we perceived that what we saw was a walled city built upon a great promontory, that jutted out from the mountain-side; and in the same breath Fray Antonio and I called out together, "It is the city of Culhuacan!"

As we uttered this name Tizoc turned towards us quickly, and with a startled, troubled look upon his face. "They are not of our race," he said, as though speaking his thoughts aloud; "yet the sacred name, that among us only a few know, is known to them!" and the troubled look upon his face deepened as we went onward.

The way by which we descended was a narrow road carried zigzag down the cliff—for the pass by which we had entered the valley was fully six hundred feet above the level of the lake—and at short intervals along its course this road was defended by walls of very solid masonry, pierced with openings so narrow that only one man at a time could pass through them. That the walls were for defence was shown by the piles of metal bars on the inner side of each opening—the side towards the mountain—so arranged that in a moment they could be slipped into sockets in the stone-work, thus closing effectually the way.

Perceiving that we regarded with surprise this curious system of fortification, Tizoc explained: "These are the barriers set up against the Tlahuicos, who, heeding not the order given of old by our lord Chaltzantzin, have striven many times to break forth from the valley—for among these men there are many of perverse natures and evil minds."

In tlahuico I recognized a Nahua word that means "men turned towards the earth," but what its meaning might be in the sense in which Tizoc employed it I did not know. I should have asked for further explanation—for the manner of this man was so frank and so friendly that it invited a cordial familiarity—but as I was about to speak we passed through the narrow opening in a wall of unusual height and strength, and so came into a charming garden, in the midst of which stood a large house well built of stone. For the making of this garden a natural nook on the side of the mountain had been enlarged by filling in along its outer edge against a great retaining-wall, built up from a depth of a hundred feet from the slope below; and on the farther side of the plateau thus created, where the path down into the valley went on again, were heavy defensive walls. Near this exit, also, was a long low building that I took to be a guard-house.

The crowd that had followed behind us from the height above went on across the plateau, and out through the gate beside the guard-house—its members casting many curious looks at us as they departed—and the guardsmen who had formed our escort, at an order from Tizoc, went on to their quarters. But Tizoc led us across the garden to the large house that stood in the midst of it, and there, with a formal courtesy, bade us enter. This was his home, he said, and we were his welcome guests.

The house was so like the houses ordinarily found in Mexico that we had no feeling of strangeness in entering it. It was built of stone neatly laid in cement; was but a single story in height, and enclosed a large central court, in the midst of which a fountain sparkled, surrounded by small trees and shrubs and beds of flowers. All of the rooms opened upon this central court, and in the outer wall the only opening was the narrow way by which we had entered—for the prompt closing of which there lay in readiness a pile of metal bars. The flat roof, also of stone, was reached by a stone stair-way from the court, and had about it a heavy stone parapet that was pierced with narrow slits through which javelins and arrows could be discharged. But these arrangements for defence did not by any means produce a gloomy effect, as they would had we encountered them in a country-house in our own part of the world—for similar defence arrangements are found in every hacienda in Mexico at the present day, and even I, though my stay in the country had been so short, already had become accustomed to them.

A buzzing chatter of talk, in which women's voices predominated, ceased suddenly as we entered the court; and from the swaying and twitching of the curtains hanging in the front of the openings leading into several of the rooms, we inferred that we were undergoing a keen inspection. In response to a call from Tizoc, some men-servants came out from one of the rooms and received his order to prepare food for us; and he then led us to a large room in a corner of the court that was arranged very delightfully as a bath. Here was a great stone tank, twenty feet or so square, and with a slanting bottom, so that the depth of it ranged from two feet to nearly five, in which was fresh running water; and over the portion of the room that the tank occupied there was no roof but the bright blue sky. On the stone floor were beautifully woven mats, and towels of cotton cloth hung upon pegs driven into the walls, and in earthen bowls were fresh pieces of a saponaceous root that I have seen the like of in use among the Indians of New Mexico. It seemed to strike Tizoc as odd that we preferred to make use of the bath successively rather than all together; but he was too polite a man to interpose any objections to our eccentricities. Pablo only—coming last of all of us—had a companion in his bathing in the person of El Sabio; and the sleekness of that excellent animal, when Pablo had brushed carefully his long coat when his bath was ended, was a wonder to behold.

Being thus refreshed, we heartily welcomed the excellent meal that was served to us in the cool shade of the veranda by which the court-yard was surrounded. Our eating was somewhat in the Roman fashion, for the table was a broad slab of stone, raised but a little from the ground, and around it we reclined upon mats, with cushions woven of rushes to lean upon. The food was excellent—a small animal of the deer species, but no larger than a hare, roasted whole; birds very like quails, delicately broiled; little cakes made of maize, which were rather like the hoe-cakes of our Southern negroes than tortillas; some sort of sweet marmalade; and a great abundance of oranges, mangoes, bananas, and other fruits common to the hot lands of Mexico; all of which fruits were much more delicate in flavor than Mexican fruits usually are; the result, as we found later, of the great care bestowed upon their culture. Only water was served with the meal, but at the end of it a small jar of some sort of potent liquor was brought, very cool, and with an excellent spicy taste, that Tizoc warned us must be taken but sparingly; and truly he was right, as I found from the warm and mellow feeling of benevolent friendliness that but half a cup of it infused into me. Tizoc himself did not follow very rigidly the advice that he had given us; and to this fact, probably, was due the exceeding frankness with which he subsequently spoke with us concerning grave matters, of which he surely would have been reticent had he been in a less genial mood.

"Just ask th' Colonel if he minds my smokin' a pipe, won't you, Professor?" Young said, when our meal was ended; and as I myself wanted to smoke, and as I was sure that Rayburn did also, I made the request general. Tizoc, to my surprise—for I believed smoking to be common to all the indigenous races—evidently did not at all understand my meaning; but perceiving that I asked to have some favor granted, he courteously gave the permission that I desired. As we filled our pipes he watched us curiously; but when we drew out our matches and struck fire by what seemed to him but the turn of our hands, he started to his feet and manifested a strange excitement, in which there seemed to be less of alarm than of awe. His voice shook, and his whole person trembled, as he asked, "Are ye the children of Chac-Mool, the God of Fire, and therefore the chosen servants of Huitzilopochtli the Terrible, that ye thus can do what among us is done only by our Priest Captain Itzacoatl?"

Both Fray Antonio and I heard with delight this utterance, that in a moment settled the long-disputed question as to whether or not Chac-Mool was an idol, and settled it, also, in favor of the ingenious hypothesis presented by the learned SeÑor Chavero. The moment was not a favorable one, however, for pursuing the matter in its archÆological bearings, for all of our tact and skill just then were required to restore Tizoc to calmness. As well as this was possible in the language common to us—we suddenly realized how difficult it was to express in the Nahua tongue more than rudimentary concepts of the ideas that we sought to convey—we explained to him how matches were made; and illustrated our words by showing him how fire was induced by friction, even as the rubbing of two pieces of wood together produced fire also. This explanation was less exact than ingenious; but it was one that he could understand, and it had the effect of allaying his alarm sufficiently to permit him to resume his seat, when he at once drank off a whole bowlful of the strong, spicy liquor at a draught. Added to what he already had inside of him, this draught set his tongue to wagging in the free way that I have already referred to, and he grew bold enough to take a match in his hand. But even in his cups he manifested a certain reverence in his handling of it; and presently, from a little bag that was hung about his neck, he produced the burnt remnant of a match that he compared with it critically. "They are the same?" he asked, as he extended the whole match and the fragment together towards us that we might examine them.

"They are the same," Fray Antonio answered. "Whence comes the one that you guard so carefully?"

"From the Priest Captain—from Itzacoatl. With such things does he miraculously set burning the fire of sacrifice; but he does not speak of them lightly, as you do; he tells us that they are the handiwork of the Fire God, Chac-Mool; and when the fire of sacrifice is kindled he gives what remains of them as high rewards to those who have served well the State by brave acts or honorable deeds. This which I cherish was my reward for crushing a revolt among the Tlahuicos."

Fray Antonio and I exchanged curious glances, for the conviction was forced upon us both that the Priest Captain of whom Tizoc spoke must either have invented friction matches, or that he must have some secret channel of communication with the outside world. In either case it was evident that he must be a man of unusual shrewdness; and it also was evident that his feeling towards us—since we also could perform a miracle that he obviously made use of as a means of manifesting his divine right to rule—must be that of strong hostility.

To Rayburn and Young, who had observed wonderingly Tizoc's extraordinary conduct, I rapidly translated what he had said; and explained how serious our situation appeared in the light of this new development.

"Well, it certainly is cold weather for this Priest Captain fellow," Young commented, "if we've got hold of his boss miracle; and I guess you're about right, Professor—he'll want t' take it out of our hides. Just poke up th' Colonel t' telling all he knows about this old dodger. Th' Colonel's got his tongue pretty well greased just now with his own prime old Bourbon—pass me that jar, Rayburn, I don't mind if I have another whack at it myself—and we may get something out of him that will be useful. Try it on, Professor, any way. Here's luck, gentlemen."

That Young's tongue also was a little greased, as he put it, by this very agreeable beverage was quite evident; but his wits were sharpened rather than dulled by the drink, and his present suggestion evidently was a very good one. As for Tizoc, his disposition towards us obviously was most soft and friendly; and as his mind slowly absorbed the fact that, somehow or another, the Priest Captain had made a fool of him with a miracle that was not really a miracle at all, his choler rose in a manner most favorable to our purposes. Yet this very feeling of resentful anger—showing a growing irreverence of one to whom all the traditions of his people gave reverence second only to that due to the gods themselves—was startling evidence of the menace that our presence was to the theocratic ruler's temporal and spiritual power. Therefore it was with a keen curiosity that we listened—and Tizoc needed, to induce him to talk freely, but little of the poking-up that Young had suggested—to what was told us concerning the strange people among whom we had come by ways so perilous, and of their chieftain, the Priest Captain Itzacoatl—with whom, as no spirit of prophecy was needed to tell us, we were destined soon to engage in a conflict that must be fought out to the very death.
