Tarzan's quest was not for Beduins but for Blake. Having assured himself that the white man in the menzil of Ibn Jad was Stimbol and that none knew the whereabouts of the other American, he was hastening back to the locality where Blake's boys had told him their bwana had disappeared, in the hope of picking up his trail and, if unable to assist him, at least to learn what fate had overtaken him.
Tarzan moved swiftly and his uncanny senses of sight and smell aided him greatly in wresting its secrets from the jungle, yet it was three days before he found the spot where Ara the lightning had struck down Blake's gun bearer.
Here he discovered Blake's faint spoor leading toward the north. Tarzan shook his head, for he knew that there was a stretch of uninhabited forest laying between this place and the first Galla villages. Also he knew that if Blake survived hunger and the menace of wild beasts he might only live to fall victim to a Galla spear.
For two days Tarzan followed a spoor that no other human eye might have discerned. On the afternoon of the second day he came upon a great stone cross built directly in the center of an ancient trail. Tarzan saw the cross from the concealment of bushes for he moved as beasts of prey moved, taking advantage of every cover, suspicious of every strange object, always ready for flight or battle as occasion might demand.
So it was that he did not walk blindly into the clutches of the two men-at-arms that guarded the outer way to the City of Nimmr. To his keen ears was borne the sound of their voices long before he saw them.
Even as Sheeta or Numa approach their prey, so Tarzan of the Apes crept through the brush until he lay within a few yards of the men-at-arms. To his vast astonishment he heard them conversing in a quaint form of English that, while understandable to him, seemed yet a foreign tongue. He marvelled at their antiquated costumes and obsolete weapons, and in them he saw an explanation of Blake's disappearance and a suggestion of his fate.
For a time Tarzan lay watching the two with steady, unblinking eyes—it might have been Numa, himself, weighing the chances of a sudden charge. He saw that each was armed with a sturdy pike and a sword. They could speak English, after a fashion, therefore, he argued, they might be able to give him word of Blake. But would they receive him in a friendly spirit or would they attempt to set upon and slay him?
He determined that he could never ascertain what their attitude would be by lying hidden among the brush, and so he gathered himself, as Numa does when he is about to spring.
The two blacks were idly gossiping, their minds as far from thoughts of danger as it were possible they could be, when suddenly without warning Tarzan launched himself full upon the back of the nearer, hurling him to the ground. Before the other could gather his wits the ape-man had dragged his victim into the concealment of the bush from which he had sprung, while the fellow's companion turned and fled in the direction of the tunnel.
The man in Tarzan's grasp fought and struggled to be free but the ape-man held him as easily as he might have held a child.
