Matt told of the illness that had so suddenly overtaken the master of the submarine.
"Shiver me, but it's main queer!" exclaimed Dick.
"For the last hour," went on Matt, "the captain's hands have been like ice and his face pale. I knew he didn't feel well, but I hadn't any idea he was as bad as this."
"Tough luck!" growled Cassidy.
"Will we need a pilot to take us into Belize?" asked Matt.
"We can't get very close to the town, but will have to lay off and go ashore in a boat. I know the place well enough to take the Grampus to a safe berth."
"Then you'd better go up in the lookout, Cassidy, and see to laying us alongside the town."
A mutinous look flickered for an instant on Cassidy's weather-beaten face. He hesitated, and then, without a word, turned away and climbed into the conning tower.
A moment more and the captain had revived and opened his eyes.
"How are you feeling, sir?" queried Matt.
