Moving silently through the trees Tarzan paralleled the course of the 'Aarab. They were often plainly visible to him; but none saw Tarzan, nor dreamed that savage eyes were watching their every move.

Five men carried the treasure, though its weight was not so great but that one powerful man might have borne it for a short distance. Tarzan watched these men most often, these and the Sheik Ibn Jad.

The trail was wide and the sheik walked beside one of those who bore the treasure. It was very quiet in the jungle. Even the 'Aarab, garrulous among themselves, were quiet, for they were very tired and the day was hot and they were unused to the burdens they were forced to carry since Batando had robbed them of their slaves.

Of a sudden, without warning and with only the swish of its flight through the air to announce it, an arrow passed through the neck of the Beduin who walked beside Ibn Jad.

With a scream the man lunged forward upon his face and the 'Aarab, warned by their sheik, cocked their muskets and prepared to receive an attack, but look where they would they saw no sign of an enemy. They waited, listening, but there was no sound other than the droning of insects and the occasional raucous cry of a bird; but when they moved on again, leaving their fellow dead upon the trail, a hollow voice called to them from a distance.

"For every jewel a drop of blood!" it wailed dismally, for its author knew well the intensely superstitious nature of the desert dwellers and how best to affright them.

It was a shaken column that continued on its way, nor was there any mention of making camp until almost sunset, so anxious were they all to leave behind this gloomy wood and the horrid afrit that inhabited it; but the forest persisted and at length it became necessary to make camp.

Here the camp fires and food relieved the tension upon their overwrought nerves, and their spirits had revived to such an extent that there were again singing and laughter in the menzil of Ibn Jad.

The old sheik himself sat in his mukaad surrounded by the five bags of treasure, one of which he had opened and beneath the light of a lantern was fondling the contents. About him were his cronies, sipping their coffee.

Suddenly something fell heavily upon the ground before the beyt and rolled into the mukaad among them. It was the severed head of a man! Glaring up at them were the dead eyes of their fellow, whose corpse they had left lying in the trail earlier in the day.
