Our use in turn of the field-glass was a mysterious performance that aroused keenly the barge-master's curiosity. I heard him ask Tizoc for an explanation of it; and Tizoc, who also was much interested, referred his question to me. Had I been dealing with Tizoc alone I should have tried to make the matter clear to him; but in the case of the barge-master, whose feeling towards us, I was convinced, was anything but friendly, I thought it wiser to be less frank. Therefore, covering the action with a negligent motion of my hand, I screwed the glasses close together, so that in looking through them there was to be seen only a mass of indistinct objects looming up in a blurred cloud of light, and so handed them to him. Naturally, neither he nor Tizoc arrived at any very satisfactory conclusion in regard to the real use of them; and from their talk it was evident that they conceived the ceremony in which we had engaged in turn so earnestly to be in the nature of a prayer to our gods. Fray Antonio was both shocked and pained by their taking this view of the matter, and was for making a true explanation to them; but at my urgent request he held his peace. Yet it was evident that he brooded over the matter in his mind, and so was led to earnest thoughts of the mission that had brought him hither into the Valley of Aztlan. Therefore was I not surprised—though I certainly was alarmed by the thought of what might be its consequences—when presently, in low and gentle tones, he began to speak to those about him of the free and glorious Christian faith, which in all ways was more excellent than the cruel idolatry in which they were bound. Naturally, he was not permitted long to speak in this strain, for the barge-master speedily ordered him in most peremptory tones to keep silence; which order doubtless would have been still more quickly given had not the officer been fairly surprised by Fray Antonio's temerity into momentary forgetfulness of the dangerous outcome of this gentle talk. And Fray Antonio, knowing the value of the word in season that is dropped to fructify in soil ready for it, did not attempt argument with the barge-master—by which the thoughts of those who listened would have been diverted from the hopeful promise of a better faith that he had offered to them—but obeyed the order meekly and so held his peace. That what he had spoken had taken hold upon the hearts of some at least among his hearers I was well assured by their grave look of thoughtfulness, and especially did Tizoc seem to be deeply moved; but—as I supposed for fear of the barge-master—there was no open comment upon what had passed.

By this time, the barge being all the while urged rapidly forward by the steady strokes of the twenty oarsmen, the city rose so broadly and so openly before us that we could see the whole of it distinctly with our naked eyes. And what at this nearer view seemed most impressive about it was its gloominess; that was due not less to the prison-like effect of its heavily built houses and its massive walls than to the dull blackness of the stone whereof these same were made. Nowhere was there sparkle, or glitter, or bright color, or brightness of any sort to be seen; and it seemed to me, as I gazed upon this sombre stronghold, that dwelling always within it well enough might wear a man's heart out with a consuming melancholy begotten of its cold and cheerless tones.

That it was indeed a stronghold was the more apparent to us the nearer that we came to it. The plan of it was that of a great fan, spread open upon the hillside, and extending also across the broad sweep of level land between the base of the promontory and the lake. The promontory had been so cut and shaped that its gentle slope had been transformed into six broad semicircular terraces, above the highest of which was a semicircular plateau of very considerable size, on which stood the Treasure-house, that also was the great temple. Along the face of each terrace, and around the face also of the plateau, a heavy defensive wall rose to a height of twenty feet or more; and from the base of the crowning plateau, thence accessible by a single broad flight of stairs—being led through openings in the rampart walls of the terraces, and down each terrace face by means of stair-ways—twelve streets descended, of which the central six ended at the water-side and the remainder against the great outer wall. It was this outer line of strong defence that gave the city—which otherwise would have corresponded curiously closely with the fortified city of Quetzaltepec, described by the Mexican chronicler Tezozomoc—its most distinctive characteristic. Such a vastly thick wall, for the great length of it, as this was I never have seen in any other place; and so solid was the building of it that it would have been proof against any ordinary train of siege artillery. For defence against a foe whose only missile weapons would be javelins and slings and bows, this great wall made the city absolutely impregnable. And that the protection that it gave might be still more complete—and also, as Tizoc explained to us, that in the case of siege the water supply might be assured, together with a supply of fish for food—the wall was carried out into the lake so far as to enclose a basin of more than four acres in extent; within which, should an enemy gain access to the valley, all the boats upon the lake could be brought together and held in safety. And finally, the one entrance to the city was by way of a tunnel-like canal cut in the wall thus rising from the water; the outer end of which canal was closed in ordinary times by a heavy grating, while in war time the inner end also could be closed by means of great metal bars.

It was towards this entrance that the barge that carried us was heading. Presently we reached it, and the grating was raised for our admission by means of chains which were operated from the top of the wall. So low and so narrow was the passage that our heads were within a few inches of the huge slabs of stone of which its roof was formed; and the rowers had need to unstep the mast and then to lay their oars inboard, while they brought the barge through by pushing with their hands against the roof and sides. The canal was fully forty feet long, and thus the enormous thickness of the wall was made apparent to us. It truly was, as I observed to Rayburn, a work that well might be attributed to the Cyclops.

"I never met a live Cyclop, Professor," Rayburn answered, "and I don't believe that these fellows ever did either; but it bothers me to know how they managed to do work like this without a steam-derrick. If we get out of here with whole skins and our hair on our heads, I hope it won't be until I've had a chance to talk to some of their engineers, and so get down to the facts."

A moment later we emerged from the tunnel through the wall, and so entered the enclosed basin that extended along the whole of the city's front. Within the basin were lying many canoes, and also boats of a larger sort that carried oars and that were rigged with a sort of lug-sail; but these all kept away from us, even as all the boats which we had seen during our passage of the lake had given us a wide berth. That our barge—one of those employed exclusively in the Priest Captain's service—was thus shunned was due, as I found later, to the wholesome dread in which the special servitors of the temple and of its head universally were held; for these very frequently abused the authority acquired through their semi-sacerdotal functions by using it as a cloak to cover acts of purely personal oppression, while at all times they were feared as the executors of their master's wrath. There was, indeed (though I did not mention this fact to Fray Antonio), a curiously close resemblance between the officials of this class and the familiars of the Inquisition, both in the duties which they performed and in the fear and hatred which they everywhere inspired.

But even dread of entanglement with the Priest Captain's servants could not restrain the curiosity of the crowd that pressed towards us on the broad pier upon which we disembarked. It was evident that this crowd was not made up of the common folk of the city, and also that it was moved by a purpose far higher than that of a mere idle longing to see something that was strange. From their dress, and still more from the beauty of their ornaments and the elegance of the arms which many of them carried, it was obvious that for the most part these men were citizens of the highest rank; and this fact was still further attested by the dignity of their demeanor and by the reverent age to which the majority of them had attained. So far from manifesting any vulgar excitement, the crowd maintained an absolute silence; and with this an exterior air of calm that was the more impressive because the eager, almost awe-struck expression upon every face showed how strong was the emotion that thus strongly was restrained. But when El Sabio, after much coaxing, crossed the gang-plank between the boat and the pier, and so came to where he could be seen of all plainly, there was a curious low sound in the air as though all at once every man in the crowd had heaved a sigh; and the sound swelled into a loud murmur as Pablo, in obedience to a quick order that I gave him in Spanish, briskly mounted upon the ass's back. In this murmur only one word was intelligible, and that I caught again and again: the prophecy!

But Pablo was no more than fairly seated upon El Sabio's back than the officer in command of our guard took him roughly by the shoulders and snatched him thence to the ground again; which act led Tizoc and me to a quick exchange of startled glances, for it showed very plainly that the Priest Captain—to whom the messenger telling of our coming into the valley had been sent before any of these people had seen Pablo mounted upon El Sabio's back—had anticipated this sign of the fulfilment of the prophecy and had given orders to prevent it. Luckily, the celerity with which Pablo had executed my quick order to mount had saved the day for us; and even more than saved it, for as we passed through the crowd, on our way from the water-side into the city, I caught here and there fragments of comment upon what had just passed which showed that not only was the sign told of in the prophecy recognized, but that the effort on the part of the officer to neutralize it was understood.

But before our going into the city there was a stirring conflict of authority concerning us between the temporal and the spiritual powers. We were no more than fairly landed, indeed, when an officer addressed the barge-master, who continued in charge of our party, and gave him a formal order to bring the strangers directly before the Council of the Twenty Lords. And to this the barge-master replied that he already was under orders to bring the prisoners, immediately upon their landing, before the Priest Captain—and there was something both curious and ominous, it struck me, in the marked manner in which the term "strangers" was employed by one of these men and the term "prisoners" by the other.

At this juncture we had further proof of the foresight of the Priest Captain, and of the determined stand that he was prepared to make rather than to suffer the miscarriage of big plans. While the barge-master and the messenger from the Council still were engaged in hot talk as to which of the two conflicting orders should be recognised, there was the sound of tramping feet and of arms clanking; and then a body of fully one hundred soldiers came quickly from behind a house that was near by the water-side and swept down on a double-quick to where we were standing at the end of the pier. The crowd, jostled aside to make way for the passage of the soldiers, evidently regarded them with astonishment; and this astonishment rapidly changed to anger as the purpose that brought them thither was made plain. In a moment they had closed in around us, separating us from the Council's messenger and from Tizoc; the barge-master placed himself at the head of them, and in sharp, quick tones gave the order to march; and the whole force, with ourselves in the centre of it, went off the pier at a round pace, and thence along a street that led towards the city's heart. Evidently acting under orders, the men broke their platoons and closed in around us; and I was well convinced that this unsoldierly marching was adopted to the end that El Sabio might not be seen.

Fray Antonio agreed with me that the Priest Captain was carrying matters with a dangerously high hand in thus opposing the will of the Council with armed force. This act of his, if Tizoc had correctly represented to us the excited condition of popular feeling, was quite sufficient in itself to stir into violent activity the slumbering fires of mutiny. But whether the revolt that we now believed must surely come would come in time to be of service to ourselves, we could not but look upon as a very open question.

"If this old scoundrel is as sharp as he seems to be," Rayburn said, "and if he keeps things up in the way he's begun, it's about all day with us. His play should be to get rid of us as quick as he can manage it; and I should judge, from the cards that he's put down, that that's precisely the way he means to manage the game. It's not much comfort to us to know that after he's cleaned us out somebody else will rake his pile."

As we talked, we went on rapidly through the city; and even the danger that we were in, and the excitement that attended this sudden shifting of our fortunes, could not prevent me from studying with a lively curiosity the many evidences of an advanced civilization that I beheld. The plan of the city, as I had discerned while we were approaching it, was that of a wide-open fan. From the Treasure-house, on the height in the centre, twelve broad streets radiated outward, of which three on the northern side and three on the southern ended against the great enclosing wall, and six came down through openings in the walls along the several terraces directly to the water-front. All of these streets were well paved with large smooth blocks of stone, and were led up the faces of the terraces by wide and easy stairs. The transverse streets were true semicircles, starting from and ending at the face of the cliff, and were carried along the outer edges of the terraces, just inside their facing walls. Rayburn was even more astonished than I was by the exactness with which these great semicircles were laid off; for he apprehended, as I did not, the difficulty attendant upon running a line in a true and regular curve. But I am not prepared to say that this work could not have been accomplished by mere rule of thumb. My friend Bandelier, in the course of his admirable analysis of the ruins at Mitla, has made clear to me how easy it is to attribute to scientific knowledge work that is the result only of manual skill. As I have pointed out in my discussion of this matter in my Pre-Columbian Conditions on the Continent of North America, the plateau at the top of this range of terraces easily might have been laid off in a true semicircle by the simple means of a pointed stick at the end of a long rope; and from the true line thus established the line of the terrace below it could have been had—and so on down to the lowest terrace of all.

There could be no doubt, however, that engineering skill of a high order—howsoever crude might have been the actual method of its application—was exhibited both in the preparation of the site, and then in the city's building. On the site alone an almost incredible amount of labor had been expended; for the rocky promontory—that primitively, as the result showed, had been broken and irregular—had been so cut away in some places, and so filled in in others, and the whole of it had been so carefully trimmed and smoothed, that in the end it became a huge mass of rock-work, in the regularity of which there was not perceptible the smallest flaw. And in this preliminary work, as well as in the building of the houses afterwards, fragments of stone were used of such enormous size that the moving of them, Rayburn declared, would be wellnigh impossible even with the most powerful engineering appliances of our own time. Nor was the use of these huge pieces of stone confined to the foundations of the houses. Some of them were high above the ground; indeed, the very largest that we observed—the weight of which Rayburn estimated at not less than twenty tons—was a single block that made the entire top course of a high wall.

All of the stone-work was well smoothed and squared; and while the exteriors of the houses were entirely plain, we could see through the open door-ways that the interiors of many of them were enriched with carvings. All were destitute of windows opening upon the street; and their dull, black walls, and the dull black of the stones with which the streets were paved, gave a dark and melancholy air to the city that oppressed us even more heavily when thus seen closely than it had when we beheld it from afar off. Yet the interior court-yards, so far as we could tell from the glimpses that we had of them through open door-ways, were bright with sunshine and gay with flowers; thus showing that the gloom of these dwellings did not extend beyond their outer walls. I observed with much interest that the provision for closing the entrances from the street was not swinging doors of wood, but either metal bars, such as we had seen in Tizoc's house, or else a metal grating, that was arranged like a portcullis to slide up and down in a groove; and I attributed the absence of wooden doors less to a desire for stronger barriers than to the comparative recentness of the acquisition of the knowledge of wood-working tools. Here, I thought, was a curious instance of development along the lines of greatest resistance; for in itself the invention and the making of a swinging door of wood was a much easier matter than was the invention and the making of these finely wrought sliding doors of hardened gold.

As for Young, the sight of all this gold-work quite took his breath away. "It regularly jolts me, Professor," he said, "t' see th' genuine stuff, that's good t' make gold dollars out of, slung around this way. A front door of solid gold is a huckleberry above Jay Gould's biggest persimmon; an' as t' Solomon, these fellows just lay Solomon out cold—regularly down th' old man an' sit on him. Why, for just that one front door of th' big house ahead of us I'd sell out all my shares in this treasure-hunt, an' be glad t' do it. But I guess I'd have to hire Samson—who was in that line of business—t' carry it off for me. It must weigh a solid ton!"

By this time we had mounted all of the terraces, and the house towards which Young pointed as he spoke was built directly beneath the crowning plateau on which the great temple stood. It was the largest and by far the most elegant house that we yet had seen, and the sliding grating of gold that closed the entrance was unusually heavy, and very beautifully wrought. Sentinels were stationed here, wearing the same uniform as that of the soldiers who formed our guard; and this further indication of the importance of the building gave us the impression that it was the dwelling of some great dignitary. Close by the portal we were halted, while the commander of our guard spoke through the grating to some one inside. A moment later the grating was slowly raised, and we were marched through the narrow entrance, and so along a short passage-way into a long, narrow chamber that obviously was a guard-room; for spears and javelins were ranged in orderly fashion upon racks, and swords and shields and bows and quivers of arrows were hung upon the walls. Here we were halted again; and while we stood silent together, wondering what might be in store for us in this place, we heard the heavy grating behind us close with a dull clang.
