“They are up to something,” said the old man. “We must watch carefully against a surprise. If the blacks would but come now, while the doorway is held by only fifty, we should overcome them easily, and have, I do verily believe, some slight chance of escaping from the palace grounds.” “Your long residence here,” said Tarzan, “has filled you with the same senseless fear of the Bolgani that the Gomangani hold. From the attitude of mind which you hold toward them one would think them some manner of supermen—they are only beasts, my friend, and if we remain loyal to our cause we shall overcome them.” “Beasts they may be,” replied the old man, “but they are beasts with the brains of men—their cunning and their cruelty are diabolical.” A long silence ensued, broken only by the nervous whisperings of the Gomangani, whose morale, it was evident, was slowly disintegrating under the nervous strain of the enforced wait, and the failure of their fellows of the forest to come quickly to their aid. To this was added the demoralizing effect of speculation upon what the Bolgani were planning or what plan they already were putting into effect. The very silence of the gorilla-men was more terrible than the din of actual assault. La was the first of the whites to break the silence. “If thirty of the Gomangani could leave the palace so easily, why might not we leave also?” she asked. “There were two reasons,” replied Tarzan. “One was that should we have left simultaneously the Bolgani, greatly outnumbering us as they did, could have harassed us and detained us for a sufficient length of time to have permitted their messengers to reach the villagers ahead of us, with the result that in a short time we should have been surrounded by thousands of hostile warriors. The second reason is that I desire to punish the creatures, so that in future a stranger may be safe in the Valley of the Palace of Diamonds.” He paused. “And now I shall give you a third reason why we may not seek to escape at this moment.” He pointed toward the windows overlooking the terrace. “Look,” he said, “the terrace and the gardens are filled with Bolgani. Whatever their plan I think its success depends upon our attempt to escape from this room through the windows, for, unless I am mistaken, the Bolgani upon the terrace and in the gardens are making an attempt to hide themselves from us.” The old man walked to a part of the room from which he could see the greater part of the terrace and gardens upon which the windows of the throne room looked.
