The ape-boy had as yet never come to a real trial of strength with a bull ape, other than in play, and so he was not at all sure that it would be safe to put his muscles to the test in a life and death struggle. Not that he was afraid, for Tarzan knew nothing of fear. The instinct of self-preservation gave him caution—that was all. He took risks only when it seemed necessary, and then he would hesitate at nothing.
His own method of fighting seemed best fitted to his build and to his armament His teeth, while strong and sharp, were, as weapons of offense, pitifully inadequate by comparison with the mighty fighting fangs of the anthropoids. By dancing about, just out of reach of an antagonist, Tarzan could do infinite injury with his long, sharp hunting knife, and at the same time escape many of the painful and dangerous wounds which would be sure to follow his falling into the clutches of a bull ape.
And so Taug charged and bellowed like a bull, and Tarzan of the Apes danced lightly to this side and that, hurling jungle billingsgate at his foe, the while he nicked him now and again with his knife.
There were lulls in the fighting when the two would stand panting for breath, facing each other, mustering their wits and their forces for a new onslaught. It was during a pause such as this that Taug chanced to let his eyes rove beyond his foeman. Instantly the entire aspect of the ape altered.
