“Ah, to be sure,” said the aviator. “The plane, you mean, eh? She is there—see?” he said, pointing to a small, single-motor cabin plane. “Now shall we take a fly over the jungle, you and the Señor uncle?”

“Sure,” they answered unanimously. And as they followed at the aviator’s heels, Rene whispered: “I kind of like this, being your Dutch uncle. And as long as he thinks so....”

“Why bother to explain, huh?” Hal returned in the spirit of the thing. “There’s not that much difference between a real uncle and a Dutch uncle anyway.”

But Hal was to learn that there was a difference as far as Rodriguez was concerned.

CHAPTER IX
EXIT RENE

When they got to the plane, Rodriguez proceeded on into his cockpit, motioning his passengers to make themselves comfortable in the tiny cabin. After a moment they were off.

They bumped across the field, then rose into the air, hesitated a moment as if they were going to fly straight for the jungle, then soared high into the blue. Hal nodded with satisfaction, after a half hour had elapsed.

“Some beautiful country,” he shouted at Carmichael. “Like a big painted canvas.”

“You wouldn’t think so if you got lost in it,” Rene shouted back. “This fellow’s taking us for quite a long hop, eh?”

Hal nodded and looked out of the tiny window down upon the endless sea of jungle over which they were passing. The plane roared on through the glistening blue and for a time neither of the young men spoke. Yet they were both aware of a peculiar sound coming from the motor. It was not missing, yet each revolution seemed more labored than the one preceding it.
