"I have sworn to serve you, Bwana, and I am a Batoro," replied Gabula.
"And I can only thank the Lord that you are a Batoro," said von Harben, "for the Lord knows that I shall need help before I reach the bottom of this canyon, and we must reach it, Gabula, unless we are content to die by starvation."
"I have brought food," said Gabula. "I knew that you might be hungry and I brought some of the food that you like," and, unrolling the small pack that he carried, he displayed several bars of chocolate and a few packages of concentrated food that von Harben had included among his supplies in the event of an emergency.
To the famished von Harben, the food was like manna to the Israelites, and he lost no time in taking advantage of Gabula's thoughtfulness. The sharp edge of his hunger removed, von Harben experienced a feeling of renewed strength and hopefulness, and it was with a light heart and a buoyant optimism that he commenced the descent into the canyon. Gabula's ancestry, stretching back through countless generations of jungle-dwelling people, left him appalled as he contemplated the frightful abyss into which his master was leading him, but so deeply had he involved himself by his protestations of loyalty and tribal pride that he followed von Harben with no outward show of the real terror that was consuming him.
The descent through the fissure was less difficult than it had appeared from above. The tumbled rocks that had partially filled it gave more than sufficient footing and in only a few places was assistance required, and it was at these times that von Harben realized how fortunate for him had been Gabula's return.
When at last they reached the bottom of the cleft they found themselves, at its outer opening, flush with the face of the cliff and several hundred feet below the rim. This was the point beyond which von Harben had been unable to see and which he had been approaching with deep anxiety, since there was every likelihood that the conditions here might put a period to their further descent along this route.
Creeping over the loose rubble in the bottom of the fissure to its outer edge, von Harben discovered a sheer drop of a hundred feet to the level of the next terrace and his heart sank. To return the way they had come was, he feared, a feat beyond their strength and ingenuity, for there had been places down which one had lowered the other only with the greatest difficulty, which would be practically unscalable on the return journey.
It being impossible to ascend and as starvation surely faced them where they were, there was but one alternative. Von Harben lay upon his belly, his eyes at the outer edge of the fissure, and, instructing Gabula to hold tightly to his ankles, he wormed himself forward until he could scan the entire face of the cliff below him to the level of the next terrace.
A few feet from the level on which he lay he saw that the fissure lay open again to the base of the cliff, its stoppage at the point where they were having been caused by a large fragment of rock that had wedged securely between the sides of the fissure, entirely choking it at this point.
The fissure, which had narrowed considerably since they had entered it at the summit, was not more than two or three feet wide directly beneath the rock on which he lay and extended with little variation at this width the remaining hundred feet to the comparatively level ground below.
