Chapter 6

After their first terror had subsided subsequent to the shock of the earthquake, Basuli and his warriors hastened back into the passageway in search of Tarzan and two of their own number who were also missing.

They found the way blocked by jammed and distorted rock. For two days they labored to tear a way through to their imprisoned friends; but when, after Herculean efforts, they had unearthed but a few yards of the choked passage, and discovered the mangled remains of one of their fellows they were forced to the conclusion that Tarzan and the second Waziri also lay dead beneath the rock mass farther in, beyond human aid, and no longer susceptible of it.

Again and again as they labored they called aloud the names of their master and their comrade; but no answering call rewarded their listening ears. At last they gave up the search. Tearfully they cast a last look at the shattered tomb of their master, shouldered the heavy burden of gold that would at least furnish comfort, if not happiness, to their bereaved and beloved mistress, and made their mournful way back across the desolate valley of Opar, and downward through the forests beyond toward the distant bungalow.

A giant in stature, a savage, fearless warrior, the huge black possessed also soul and judgment in proportion to his bulk and his ferocity.

Not once since his master had departed had he been beyond sight or sound of the bungalow, except when Lady Greystoke chose to canter across the broad plain, or relieve the monotony of her loneliness by a brief hunting excursion. On such occasions Mugambi, mounted upon a wiry Arab, had ridden close at her horse's heels.

The raiders were still a long way off when the warrior's keen eyes discovered them. For a time he stood scrutinizing the advancing party in silence, then he turned and ran rapidly in the direction of the native huts which lay a few hundred yards below the bungalow.

Here he called out to the lolling warriors. He issued orders rapidly. In compliance with them the men seized upon their weapons and their shields. Some ran to call
