"And if he ever saw a robber," added Frank, "he'd run hard to get away from him."
"Of course I would," admitted Sammy. "And so would you, too. But they can't hang around their caves all the time, and we might keep watch and slide in when there was nobody there. There's no telling what we might find."
"Well, we won't count the money just yet anyway," said Bob with a grin. "But speaking of water has made me so hot that I'm going in for a swim. Come along, fellows, and see who'll get his bathing suit on first. Maybe we won't have many more chances and we'd better make the most of them."
They broke into a run, reached the cottage, and soon had slipped into their bathing shirts and trunks.
"The last one in is a Chinaman," sang out Bob, gaily, as the three made a dash for the beach.
They struck the water so nearly at the same time that each denied being a Chinaman and none of the others could prove it.
The water was delightfully cool and refreshing after their trip to the village in the hot sun, and they splashed around merrily.
"Say, fellows, let's swim over to the place where the pirate ship was wrecked," suggested Sammy, as he rose, puffing and blowing, from a longer dive than usual.
"Pirate ship nothing!" snorted Bob. "There you go again, Sammy."
"Well, you don't know that it wasn't," retorted Sammy. "There's part of a ship of some kind wrecked there, and it might just as well have been a pirate as any other kind."
