"I am a noble of Castile who came to help conquer Florida, and my name is De Vaca," said the oldest man. "The fleet was wrecked and all were lost except my companions here, and me. All the years since we have been with the Indians."

"I do not believe a word of it," said the Captain. "Put these fellows in prison until we find out about them. They may be criminals."

For three months they lay in prison, and then the Alcalde came and released them.

"Tell me your story," he said.

"When the ships were lost," responded De Vaca, "we swam to the mainland, and were captured by the Indians. They were a poor, starved tribe who lived on roots and berries, and often went days without a mouthful. We had with us a rattle, and this, with our beards, made them think we came from Heaven, and were great medicine men. They fell on their faces before us and gave us all they had. We asked them to take us where the sun sets, but they refused, and we pretended to be very angry, until they finally let us go. After months of wandering we came to a land of plenty, where the people were wealthy, and wore beautiful plumes in their head-dresses. They brought us five emeralds cut into arrow-heads, and many fine turquoises, and beads made of coral. When I asked where they got these stones, they pointed to some lofty mountains toward the north and told us the gems came from there, and that near them were large cities, with houses three or four stories high. I did not go there because I heard that toward the sunset were other men of my kind, and I longed once more to look upon the face of a Spaniard."

"Of course," said the people, as they talked the matter over, "these are the same cities Guzman tried to find. He did not go in the right direction, but we know where they are," and many were eager to set out at once. But the Viceroy was a quiet and careful man.

"There have been many lives lost already," he said, "and it will be best not to hurry. I shall not send an army there until I am sure."

Then he thought of a padre, named Fray Marcos, who had lived much among the Indians of the north, and he sent for him, and said:

"Perhaps there lies to the north as rich a nation as Mexico or Peru. If so it must be conquered for the Church and the King of Spain. You know how to speak to the Indians, and it might be that they would let you come among them and learn the truth. Will you undertake to do so?"

"God giving me strength I will," said Fray Marcos, with enthusiasm.
