“Ah, ’tain’t nice to think about, is it, lads?” continued the American; “much better to stop here and grow yellow oranges—not that I’ve found it so,” he continued, with a sigh. “It’s all been one horrible disappointment. Still one is alive and well, while that poor fellow—”

“But he’s very, very old,” said Chris.

“Old? Awful. Looks old too, from what he’s gone through. I should say he has starved, and been dried-up with thirst, and been hunted by those brutes of plain Indians, and had all his seven senses driven out of him. But maybe I’m all wrong, after all.”

“And my father won’t let him,” cried Chris excitedly. “Look, he’s going to do something for the poor fellow now.”
