“Only wood burning.”
“Well, that means a campfire!”
“But who would be building a campfire in this wilderness?” demanded Case. “Perhaps the chimney of your hotel smokes!” he added, laughingly.
“That is for us to find out!” Frank replied, and Case detected a tone of anxiety in his voice. “If anyone has been in here, looking around, why, my cargo——”
“What about your cargo?” asked Case, as the other stopped suddenly.
“Why, it will be gone,” Frank admitted, in a moment.
Directly Case caught his companion by the arm and pointed straight ahead into the jungle.
“There is where the smoke comes from,” he explained. “There’s a fire in the thicket yonder, and men moving around it.”
Frank followed the direction of the pointing hand and grasped his companion by the arm.
“We may as well go back,” he whispered. “Those men are here because they know about my cargo. If we move silently, they will not know that we are here. Come along! They must not see me to-night!”
