"My Lord, I may go no farther," said the Cambodian.The young white man turned in astonishment upon his native guide. Behind them lay the partially cleared trail along which they had come. It was overgrown with tall grass that concealed the tree-stumps that had been left behind the axes of the road-builders. Before them lay a ravine, at the near edge of which the trail ended. Beyond the ravine was the primitive jungle untouched by man."Why, we haven't even started yet!" exclaimed the white man. "You cannot turn back now. What do you suppose I hired you for?""I promised to take my lord to the jungle," replied the Cambodian. "There it is. I did not promise to enter it."Gordon King lighted a cigarette. "Let's talk this thing over, my friend," he said. "It is yet early morning. We can get into the jungle as far as I care to go and out again before sundown."The Cambodian shook his head. "I will wait for you here, my lord," he said; "but I may not enter the jungle, and if you are wise you will not.""Why?" demanded King.
