A few moments later another party came out of the forest and passed into the palace grounds. This consisted of fully fifty armed Bolgani and twice as many black warriors with spears and axes. Entirely surrounded by these armed creatures were four brawny porters, carrying a small litter, upon which was fastened an ornate chest about two feet wide by four feet long, with a depth of approximately two feet. The chest itself was of some dark, weather-worn wood, and was reinforced by bands and corners of what appeared to be virgin gold in which were set many diamonds. What the chest contained Tarzan could not, of course, conceive, but that it was considered of great value was evidenced by the precautions for safety with which it had been surrounded. The chest was borne directly into the huge, ivy-covered tower at the northeast corner of the palace, the entrance to which, Tarzan now first observed, was secured by doors as large and heavy as the east gate itself. At the first opportunity that he could seize to accomplish it undiscovered, Tarzan swung across the jungle trail and continued through the trees to that one in which he had left the body of the Bolgani. Throwing this across his shoulder he returned to a point close above the trail near the east gate, and seizing upon a moment when there was a lull in the traffic he hurled the body as close to the portal as possible. “Now,” thought the ape-man, “let them guess who slew their fellow if they can.” Making his way toward the southeast, Tarzan approached the mountains which lie back of the Valley of the Palace of Diamonds. He had often to make detours to avoid native villages and to keep out of sight of the numerous parties of Bolgani that seemed to be moving in all directions through the forest. Late in the afternoon he came out of the hills into full view of the mountains beyond—rough, granite hills they were, whose precipitous peaks arose far above the timber line. Directly before him a well-marked trail led into a canyon, which he could see wound far upward toward the summit. This, then, would be as good a place to commence his investigations as another. And so, seeing that the coast was clear, the ape-man descended from the trees, and taking advantage of the underbrush bordering the trail, made his way silently, yet swiftly, into the hills. For the most part he was compelled to worm his way through thickets, for the trail was in constant use by Gomangani and Bolgani, parties passing up it empty-handed and, returning, bearing blocks of granite. As he advanced more deeply into the hills the heavy underbrush gave way to a lighter growth of scrub, through which he could pass with far greater ease though with considerable more risk of discovery. However, the instinct of the beast that dominated Tarzan’s jungle craft permitted him to find cover where another would have been in full view of every enemy. Half way up the mountain the trail passed through a narrow gorge, not
