As Tarzan opened the door nearest him it creaked upon its hinges, giving forth the first audible sound that had resulted from his investigations up to this point. The interior of the apartment before him was unlighted, and as Tarzan stood there in the entrance in statuesque silence for a few seconds following the creaking of the hinge, he was suddenly aware of movement—of the faintest shadow of a sound—behind him. Wheeling quickly he saw the figure of a man standing in an open doorway upon the opposite side of the landing. CHAPTER XII THE GOLDEN INGOTS ESTEBAN MIRANDA had played the rôle of Tarzan of the Apes with the Waziri as his audience for less than twenty-four hours when he began to realize that, even with the lee-way that his supposedly injured brain gave him, it was going to be a very difficult thing to carry on the deception indefinitely. In the first place Usula did not seem at all pleased at the idea of merely taking the gold away from the intruders and then running from them. Nor did his fellow warriors seem any more enthusiastic over the plan than he. As a matter of fact they could not conceive that any number of bumps upon the head could render their Tarzan of the Apes a coward, and to run away from these west coast blacks and a handful of inexperienced whites seemed nothing less than cowardly. Following all this, there had occurred in the afternoon that which finally decided the Spaniard that he was building for himself anything other than a bed of roses, and that the sooner he found an excuse for quitting the company of the Waziri the greater would be his life expectancy. They were passing through rather open jungle at the time. The brush was not particularly heavy and the trees were at considerable distances apart, when suddenly, without warning, a rhinoceros charged them. To the consternation of the Waziri, Tarzan of the Apes turned and fled for the nearest tree the instant his eyes alighted upon charging Buto. In his haste Esteban tripped and fell, and when at last he reached the tree instead of leaping agilely into the lower branches, he attempted to shin up the huge bole as a schoolboy shins up a telegraph pole, only to slip and fall back again to the ground. In the meantime Buto, who charges either by scent or hearing, rather than by eyesight, his powers of which are extremely poor, had been distracted from his original direction by one of the Waziri, and after missing the fellow had gone blundering on to disappear in the underbrush beyond. When Esteban finally arose and discovered that the rhinoceros was gone, he saw surrounding him a semi-circle of huge blacks, upon whose faces were written expressions of pity and sorrow, not unmingled, in some instances, with a tinge of contempt. The Spaniard saw that he had been terrified into a practically irreparable blunder, yet he seized despairingly upon the only excuse he could conjure up.
