itself not alone with his hunting, but with many other subjects. He had a habit of recalling often the events of the preceding days and hours. He lived over his visit with Tantor; he cogitated upon the digging blacks and the strange, covered pit they had left behind them. He wondered again and again what its purpose might be. He compared perceptions and arrived at judgments. He compared judgments, reaching conclusions not always correct ones, it is true, but at least he used his brain for the purpose God intended it, which was the less difficult because he was not handicapped by the second-hand, and usually erroneous, judgments of others.
And as he puzzled over the covered pit, there loomed suddenly before his mental vision a huge, gray-black bulk which lumbered ponderously along a jungle trail. Instantly Tarzan tensed to the shock of a sudden fear. Decision and action usually occurred simultaneously in the life of the ape-man, and now he was away through the leafy branches ere the realization of the pit's purpose had scarce formed in his mind.
Swinging from swaying limb to swaying limb, he raced through the middle terraces where the trees grew close together. Again he dropped to the ground and sped, silently and light of foot, over the carpet of decaying vegetation, only to leap again into the trees where the tangled undergrowth precluded rapid advance upon the surface.
