“The imaginings of childish minds,” said the professor. “However, why, my dear lieutenant, did you honor me by visiting my island?” The officer hesitated a moment before answering, his eyes running about over the assembly as though in search of someone. “Well, Professor Maxon, to be quite frank,” he said at length, “we learned at Singapore the personnel of your party, which included a former naval officer whom we have been seeking for many years. We came to your island to arrest this man—I refer to Doctor Carl von Horn.” When the lieutenant learned of the recent disappearance of the man he sought, he expressed his determination to push on at once in pursuit; and as Professor Maxon feared again to remain unprotected in the heart of the Bornean wilderness his entire party was taken aboard the cutter. A few miles up the river they came upon one of the Dyaks who had accompanied von Horn, a few hours earlier. The warrior sat smoking beside a beached prahu. When interrogated he explained that von Horn and the balance of his crew had gone inland, leaving him to guard the boat. He said that he thought he could guide them to the spot where the white man might be found. Professor Maxon and Sing accompanied one of the officers and a dozen sailors in the wake of the Dyak guide. Virginia and Bulan remained in the cutter, as the latter was still too weak to attempt the hard march through the jungle. For an hour the party traversed the trail in the wake of von Horn and his savage companions. They had come almost to the spot when their ears were assailed by the weird and blood curdling yells of native warriors, and a moment later von Horn’s escort dashed into view in full retreat. At sight of the white men they halted in relief, pointing back in the direction they had come, and jabbering excitedly in their native tongue. Warily the party advanced again behind these new guides; but when they reached the spot they sought, the cause of the Dyaks’ panic had fled, warned, doubtless, by their trained ears of the approach of an enemy. The sight that met the eyes of the searchers told all of the story that they needed to know. A hole had been excavated in the ground, partially uncovering a heavy chest, and across this chest lay the headless body of Doctor Carl von Horn. Lieutenant May turned toward Professor Maxon with a questioning look. “It is he,” said the scientist. “But the chest?” inquired the officer. “Mlaxon’s tleasure,” spoke up Sing Lee. “Hornee him tly steal it for long time.” “Treasure!” ejaculated the professor. “Bududreen gave up his life for this. Rajah Muda Saffir fought and intrigued and murdered for possession of it! Poor, misguided von Horn has died for it, and left his head to wither beneath the rafters of a Dyak long-house! It is incredible.” “But, Professor Maxon,” said Lieutenant May, “men will suffer all these things and more for gold.” “Gold!” cried the professor. “Why, man, that is a box of books on biology and eugenics.”
