"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.
