Upon the plain, below the City of Nimmr, Tarzan had overtaken the party of Beduins led by Abd el-Aziz, and after assuring himself that the girl was not with them he had turned without revealing himself to them and hurried northward to take up the trail of the other party.

Requiring food and rest he lay up in the Wood of the Leopards during the heat of the day after stalking Horta the boar and making a quick kill. His belly filled, the ape-man found a high flung tree crotch where there was little likelihood of the heavy leopards of Nimmr disturbing his slumbers, and here he slept until the sun was sinking behind the western mountains. Early the following morning he reached the deserted menzil where Ibn Jad's people had camped during his incursion of the Valley of the Sepulcher.

Some time since, he had lost the spoor of Blake, but that of the girl frequently recurred, and as her rescue now took precedence over other considerations he followed doggedly along the trail of Ibn Jad. For a time he was mystified by the fact that Guinalda's spoor, well marked by the imprints of the tiny sandals of medieval design, did not appear among the footprints of those who left the Beduin menzil.

He lost some time searching about in an effort to discover a clew to the riddle and presently he hit upon the truth, which lay in the fact that Guinalda's light sandals having been badly worn by her journey and far too tight for comfortable walking she had been given a pair belonging to Ateja, and thus it became difficult to differentiate between the spoor of the two girls, who were of equal weight and of a similarity of carriage that rendered their footprints practically identical.

Tarzan therefore contented himself with following the spoor of the party, and so it was that he passed their first night's camp, where Fahd had stolen Guinalda from the sheik, without discovering that three of its members had there turned to the west, while the main body of the 'Aarab marched toward the east.

And as Tarzan followed the spoor of Ibn Jad a hundred stalwart Waziri moved northward from the water hole of the smooth, round rocks upon the old trail of the Beduins. With them was Zeyd, who had begged so hard to accompany them when they passed the village where he had been waiting that at last the sub-chief had consented.

When Tarzan overtook the 'Aarab they had already turned south around the eastern end of the Mountains of the Sepulcher. He saw the bags they carried and the evident concern with which Ibn Jad watched and guarded them, and he shrewdly guessed that the wily old thief had indeed found the treasure he had sought; but he saw no evidence of the presence of the Princess, and Stimbol, too, was missing.

Tarzan was furious. He was furious at the thieving Beduins for daring to invade his country and he was furious at himself because he felt that in some way he had been tricked.

Tarzan had his own methods of inflicting punishment upon his enemies and he had, as well, his own grim and grisly sense of humor. When men were doing wrong it pleased him to take advantage of whatever might cause them the greatest suffering and in this he was utterly ruthless with his enemies.

He was confident that the 'Aarab thought him dead and it did not suit his whim to reveal their error to them at this time, but it did accord with his fancy to let them commence to feel the weight of his displeasure and taste the first fruits of their villainy.
