"Let's make a trip through now, just for fun," suggested Blake to Joe one day, when they had packed up their cameras.
Permission was readily granted them to make a pleasure trip through to Panama, and it was greatly enjoyed by both of them.
"Just think!" exclaimed Blake, as they sat under an awning on the deck of their boat, and looked at the blue water, "not a thing to do."
"Until the next time," suggested Joe.
"That's right—we never do seem to be idle long," agreed Blake. "I wonder what the 'next time' will be?"
And what it was, and what adventures followed you may learn by reading the next volume of this series, to be called "The Moving Picture Boys Under the Sea; Or, The Treasure on the Lost Ship."
"Here you go, Blake!" cried Joe, a few days later. "Letter for you!"
"Thanks. Get any yourself?"
"Yes, one."
"Huh! How many do you want?" asked Blake, as he began reading his epistle. "Well, I'll soon be back," he added in a low voice, as he finished.
