“We’d better get as much out of this as we can,” remarked Joe. “There won’t be a chance to enjoy this sport in Brazilian waters.”

“No,” put in Bob. “The alligators and piranhas and other dangerous forms won’t give us a chance to even wade.”

The youths were not the only ones to invade the swimming pool, however. As they neared the tropics, and the temperature steadily went up, people from all over the ship enjoyed its cool retreat, the pool becoming almost crowded. It was great fun. Nothing to do but just splash about.

Games also held the boys’ attention. Shuffleboard, quoits, deck tennis, horseshoes, and other activities played an important part in the daily life, and in times when they desired more quiet entertainment, the library, with its scores of books of all types, afforded interesting occupation.

Many leisure hours were spent conversing with Captain Crowell, who always had a humorous tale to tell. On one occasion, when they had been at sea nearly a week, Bob and Joe happened upon him standing at the rail, gazing up at the sky, on his face a worried expression.

“Big storm coming,” he said, after the salutation.

“A storm!” cried Joe and then looked upward.

Sure enough, clouds were banking heavily, and the sun was nowhere in sight. A stiff breeze had arisen, and with this came the smell of rain.

An officer came up and handed a slip of paper to the captain. He read it, and then, with a parting word for Bob and Joe, he turned and went toward the bridge.
