conveyed to them by wild Indians who had come by chance upon the valley wherein it was, was evidence enough of the security of its concealment. There was nothing surprising, consequently, in the fact that the Spaniards had not discovered it when they first overran Mexico, nor that it had remained unknown to the Mexicans of modern times. As is well known, there are to this day prodigious areas in Mexico which remain utterly unexplored. In the region west of Tampico; in the north-western States of Sinaloa, Durango, and Sonora; or in the far southern States of Oajaca and Chiapas, a valley as great as that in which the City of Mexico now stands might lie utterly hidden and unknown. And if, as the Indian's narrative implied, this particular valley had been selected deliberately because it was so hidden and so inaccessible, and if the described precautions had been taken to isolate its inhabitants, it very well might have continued to be lost in its deep concealment through an almost infinite range of years. That it never had been found since the Spaniards came into Mexico we were absolutely certain, for the outcry over so great a wonder would have echoed throughout the whole of the civilized world. Finally, in the name of the city, Culhuacan, we had a substantial fact which connected the extraordinary story that had come to us so strangely with matters within our own knowledge. For this name not only is given in the Aztec traditions as that of the sacred spot in which their god Huitzilopochtli spoke to them, but survives until this present day in the name of the village that lies at the foot of the sacred mountain, in the Valley of Mexico, called by the Aztecs the Hill of Huitzachtla, and by the Spaniards the Hill of the Star—on which, at the end of each cycle of fifty-two years, the sacred fire was renewed. Surely it was no accident that had caused the name Culhuacan to be given to this village on this sacred spot; rather must it have been so named by the elect few to whom the secret was known as a perpetual reminder to them of the reserve of men and treasure upon which they could draw should danger threaten their country and their gods.
"No doubt," said Fray Antonio, "what is here told of a secret record, known only to the priests, supplies one of the lapses in the pictured history of the Aztec migration; but as we know not which break in the history is thus filled in, we have no clew whatever as to the whereabouts of this hidden place. Nor have we any clew as to the whereabouts of the mission of Santa Marta, whence we might go onward, guided by the carvings upon the rocks, until we found at last the place we sought. The mission of Santa Marta, where my brother Francisco long ago ministered, might have been anywhere in all Mexico; and being so small a mission, and enduring for so short a period, it is not likely that any record of it anywhere has been preserved. Had we but the map and the token of which my brother writes, our way would be clear; without these guides it well may be a toilsome way and long. Yet do I know," Fray Antonio continued, earnestly, "that I shall find this hidden city. In my soul is a strong and glad conviction that God has called me to the most glorious work of carrying to the heathen dwelling there the message of His saving love. He has worked one miracle already to call me to this duty; in His own good time and way I doubt not that He will work another miracle by which I may be set in the way of its accomplishment."
As Fray Antonio spoke of the map of the Aztec migration, a hope came into my heart that, as I considered it, seemed surely to be a certainty. In the excitement of listening to this strange letter—concerning which not the least strange matter was, that between the writing and the reading of it had passed three hundred and fifty years—I had forgotten my own discoveries, and that my purpose was to show him the pictured paper and the curious piece of gold. But as he spoke of the migration this matter was called to my mind suddenly; and then in an instant the conviction thrilled through me that the clew which would lead us to the hidden city was in my possession.
"God already has worked that other miracle," I cried, joyfully. "Here is the token, and here is the map that shows the way!" and, so speaking, I opened the snake-skin bag that I had taken from the breast of the dead Cacique and drew forth its precious contents.
For myself, I needed no additional proof that here was all that was needful to guide us to the hidden city. Yet was I glad that in so grave a matter we should have added to absolute conviction the weight of absolute proof. And this we had most clearly; for Fray Antonio, cooler than I, compared the drawing in the letter with the engraving upon the piece of gold, and found the two to be essentially identical, save that the engraving lacked the sign of the arrow pointing the way.
"And now," I cried, enthusiastically, "for such discoveries in archæology as the world has never known!"
"And now," said Fray Antonio, speaking slowly and reverently, "for such glorious work in God's service as has been granted but rarely to man to do!"

THE ENGINEER AND THE LOST-FREIGHT MAN.
That the weight of a strange destiny was pressing upon us, neither Fray Antonio nor I for a moment doubted. It was something more than chance, we believed, that had brought us together, and that thereafter, by such extraordinary means, had put into our hands, in places far asunder, yet at almost precisely the same moment, these two ancient papers; either of which, alone, would have been meaningless; but the two of which, together, pointed clearly the way to a discovery so wonderful that the like of it was not to be found in all the history of the world.
At the moment that I comprehended how great an adventure was before me, and what honorable fame I was like to get out of it, I determined that I would keep the whole matter secret from my fellow-archæologists until I could tell them, not what I intended doing, but what I actually had done—for I had no desire to divide with any one the honors that fairly would be mine when I published to the world the result of my investigation of this hidden community that had survived, uncontaminated, from prehistoric times. Having this strong desire within me, it was with great pleasure that I acceded to Fray Antonio's request that our project of discovery should not be published abroad. His motive for secrecy, as I presently perceived, was bred of the one single strain of human weakness that ever I found in him. Even as I was determined that no other archæologist should share with me the honor of discovering this primitive community, so was Fray Antonio determined that to him alone should belong the glory of carrying into that region of dense heathen darkness the radiant splendor of the Christian faith. If this were sin on his part, it certainly was a sin that he shared with many saints long since in Paradise. Even the blessed Saint Francis himself, when, at the Council of Mats, he portioned out among his followers the heathen world that they might preach everywhere Christianity, reserved for himself Syria and Egypt; in the hope that in one or the other of those countries he might crown his labors by suffering a glorious martyrdom. And perhaps in this matter Fray Antonio was not unmindful of the example set him by the great founder of the Order to which he belonged.
But while we were thus firmly decided to keep to ourselves the honors that so great an archæological discovery and so great a Christian conquest must bring to us severally, we perceived that it would not be the part of prudence to essay our adventure without any companions at all. Some portion of the country through which we were to pass we knew to be frequented by very dangerous tribes of Indians, against the assaults of which two lonely men—neither of whom had any knowledge whatever of the art of war—could make but a poor stand. And even should we escape the wild Indians, we knew that we might get into many evil straits in which our lives might be ended, yet through which a larger company might pass in safety. And for my own part, I must confess that I had a strong desire to have with me some of my own countrymen. For the gallantry of the Mexicans, which gallantry has been proved a thousand times, I have the highest respect; yet is it a natural feeling among Anglo-Saxons that when it comes to facing dangers in which death looms largely, and especially when it comes to a few men against a company of savages, and standing back to back and fighting to the very last, Anglo-Saxon hearts are found to be the stanchest,
