“They don’t taste so,” remarked Bob, continuing to eat the fruit, which smelled delicious and had a fine appearance. “Better have some, Ned.”
“No, thanks. Camp stuff is good enough for me when I’m not sure of what the other is.”
Bob continued to enjoy himself on the fruit, which certainly was tempting. He only laughed at the warnings of his companions, and filled his pockets with the yellow things, a number of which he took back to camp.
In accordance with the plan of the previous night, the boys maintained a watch. The fish-line alarm was set again, and with a lantern burning down near the boat, where it would disclose any persons who might try to sneak up and cut the mooring lines, Ned and Jerry prepared to turn in. It was Bob’s turn to stand first watch. The boys had not lost their uneasy feeling concerning the professor, and they hoped every moment to hear his cheery hail as he returned.
“Don’t you wish you’d brought some of the mangoes?” asked Bob of his chums, producing some of the yellow fruit as he prepared to begin his tour of duty. “This will keep me awake.”
“Call us at the slightest sign of danger,” cautioned Jerry, as he went inside the tent.
It seemed that he and Ned had been sleeping but a short time when they were suddenly aroused by Bob shaking them.
“What is it? The negroes again?” asked Jerry as he sat up and grabbed his gun.
