The negroes he had with him were brawny fellows, willing to do almost anything he ordered.
Presently Bob, feeling rested, sprang up and began to walk around near the entrance to the cave, and then toward a nearby pool of water.
His course took him out of sight of his companions, and close to where Farvel and the negroes lay concealed in the tall grass and trailing vines.
As the boy approached, a sinister look came over the man's face, and he whispered a few words to his black companions. They evidently understood, and nodded in agreement with him.
Bob had just procured his drink and was watching the flight of several birds near by, when he felt himself clutched from behind.
Before he could make the slightest outcry a hand was clapped over his mouth, and he was lifted from his feet and borne into the jungle.
Bob's eyes were wide open and he easily saw who had made him captive.
The natives carried him with ease, while it was Joseph Farvel's hand which was clapped over his mouth.
After several hundred feet had been covered, he was set down, and a handkerchief gag was inserted in his mouth.
"Make an outcry and you will be sorry for it," said Joseph Farvel, grimly.
