"I don't know, Glennie, but I wouldn't trust Sandoval the length of a lead line. I wish we could dive! Call down and ask Dick what he and Clackett are doing, if anything."
Glennie bent down beside the tower and put the question.
"They haven't found the trouble yet," said Glennie, lifting his head out of the tower.
"That means," remarked Matt, "that we've got to face Sandoval."
"Ah!" shouted Carl, "dere goes a flag signal."
The signal was a common one, and Matt did not have to send for his code book.
"Wish to communicate with you," read the flags; "come alongside."
"'Communicate with you,'" repeated Matt. "That sounds rather mild—for Sandoval. Get us alongside, Glennie."
"Don't you go aboard the war ship, Matt," cautioned Glennie.
