TARZAN AND THE LOST EMPIRE
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.
If he and Gabula could but get into this crevice he knew that they could easily brace themselves against its sides in such a way as to descend safely the remaining distance, but how with the means at hand were they to climb over the
