"By names, yes, sir. But I'm afraid I've got lots yet to learn."

"I should say you had. You know about as much how to sail a ship as

Captain Spark believed in making boys know their place, and he made
up his mind he had a hard subject in Bob. Still, he was determined

"When do you expect to get into the Southern Pacific?" asked Bob, as

"It all depends on what weather we have. Why?"

the wrinkled piece of parchment. "He says there is treasure buried
on an island in the Southern Pacific."

"Treasure? Let me see."

on the yellow sheet.

"I'm afraid somebody has been playing a joke on you, or on Captain
Obed," he remarked, handing the parchment back, after Bob had told
him how he became possessed of it.

"A joke?"
