“Oh no, he isn’t,” laughed Terry. “He’s the whole show! He’s the Big Chief. He’s king! And Rosa is a queen, a very big queen!”

The queen herself brought them their breakfast, more strange food, more fish, more bananas. Pedro had already eaten and was on his way with his men to the beach to help Joe and Bud.

The morning seemed long. There was nothing to do but watch the flashes of color in the dome. And even Terry lost some of her enthusiasm at the monotony of the playing light. Finally it got on her nerves.

Suddenly a black face appeared at the opening. A hissing sound came from the thick lips, then the face disappeared.

“What do you make of that?” asked Prim. “Do you suppose that hiss can be translated to mean the same as in our language? Are they hissing us, and why?”

Terry was already making her way up the steep wall of the cave. “I don’t know what it’s all about, but I’m going to find out,” she called back.

As Terry reached the opening, she heard the hum of a motor overhead. Then she ducked back quickly, for there was only one man in the plane. He had banked and circled low, and Terry had seen that mocking face.

It was Joe Arnold!
