“I’m not going very far,” replied the professor. “All I want is my net and box,” and with these only he started off.
It was about an hour later when Jerry observed:
“Doesn’t it seem as if the monkeys were making more noise than usual?”
The boys listened for a few seconds. It was evident that something had disturbed these nimble inhabitants of the forest, for they were yelling and chattering at a great rate.
“Maybe another jaguar is after them,” suggested Bob.
“No; it doesn’t sound like that,” said Jerry. “They seem to be yelling more in rage than in fear.”
“Maybe they’re having a fight,” put in Ned.
Just then there came a crashing, as if several trees were being crashed down by a tornado. There was a crackling of the underbrush and a rustling in the leaves. Then, above this noise and the yells of the monkeys, sounded a single cry:
“Help, boys!”
“The professor’s in trouble again!” cried Jerry. “I wonder what it is this time?”
