"Where did it come from?" he asked, finally.

"From the beach at Puerto Santo. My little son Diego picked it up, the
day before I came away from the island."

"Now that is curious. I was just telling the young ones about an
adventure of my youth, when Gonsales Zarco touched there on his way to
Madeira. With your good permission I will leave you for a few minutes
and rummage in an old sea-chest, and see whether there is any flotsam in
it to compare with this."

Left alone with the stranger, Fernao and Beatriz looked at him with shy
curiosity. They had seen him before, and knew him to be a mapmaker in
the King's service, but he had never before been within speaking
distance. He seemed to like children, for he smiled at them very kindly
and spoke to them almost at once.

"And you were hearing about the discovery of Madeira?"

"Ay, Senhor," Beatriz answered with demure dignity.

"I live not very far from that island. It seems like living on the
western edge of the world."

"Senhor," asked Fernao with sudden daring, "what is beyond the edge of
the world?"

"There is no edge, my boy. The world is round--like an orange."[2]
