In fear and trembling the naturalist came from his sheltering rock. He seemed in momentary fear lest he might be greeted with a shower of the nuts, but none fell. With rapid strides he crossed the clearing and joined the boys.

“How did it all happen?” asked Jerry, as soon as the professor had recovered his breath.

“It was all my fault,” explained the naturalist. “I was collecting some butterfly specimens, when I happened to see some monkeys in the cocoanut trees. I had read that if any one threw something at the beasts they would retaliate by throwing down cocoanuts. I wanted to test it, so I threw a few stones at the monkeys. They returned my fire with interest, so I was forced to run under the rock for shelter.

“There were only a few monkeys at first, but more came until there were thousands. They kept throwing cocoanuts until the ground was covered. It’s lucky you came when I called.”

“It’s luckier the jaguar came along when he did,” said Jerry.

“Let’s get back to the auto before I get into any more trouble,” suggested the professor. “I do seem to have the worst luck of getting into scrapes.”

Half an hour later the travelers were on their way. It was getting well along into afternoon and they were beginning to think of where they would spend the night.

They were getting deeper and deeper into the forest, and the way became more and more difficult to travel. But they would not turn back, for they felt they were on the right path.

At length they came to a place where creepers and vines were so closely grown across the path that nothing short of hatchets could make a way. The boys got out the small axes kept for such emergencies, and, after an hour’s work, made a passage.
