“Jerry!” he called. “Is that you?”
“That’s who it is! I was just thinking I had met an Indian or a colored man. See anything of the boat?” and Jerry stepped from behind the bushes and confronted his chum.
“Not a sign. Did you?”
“No, and between us, we completed the circuit of the island. Must be about six miles around it.”
“No boat,” murmured Ned. “What are we going to do?”
“Land only knows. This island is still floating, and it seems to be continually moving in the same general direction—that is south. Maybe the boat is drifting also and we’ll catch up to her or she will with us.”
“I hope so. But we’d better go back now. I hate to take bad news to the professor, though.”

“I’m afraid of the result if he doesn’t get different medicine soon,” he said.
