Without more ado Wilson let himself slowly over the edge. He slipped the length of the sleeves, his feet dangling in the air over what depth he did not know. He swung his toes in either direction and felt them strike the opposite wall. He lowered himself a bit more, and his toe rested upon what seemed a firm platform. He was on a projection from the opposite cliff face which slanted under. He let go the sleeve and looked down. He found he could step from here to a narrow path upon the nigh side where at this point the two walls came almost together. He was now beneath the place where he had started, which hung over him like a canopy. The walls again separated below, revealing a dark cavern.
At the end of a few steps taken with his face flat to the rock, he found himself again on a narrow trail 250 which threaded its way over a yawning chasm. He moved slowly, shuffling one foot ahead and dragging the other after it. In this way he had gone perhaps one hundred feet when the path seemed to come to an abrupt end. His foot dangled over nothing. He almost lost his balance. When he recovered himself, he was so weak and dizzy that it was with difficulty he clung to the rock. In a moment he was able to think. He had been moving on a downward slope and it was probable that this was only a more abrupt descent in the shape of steps. One thing was sure: the path did not end here, if it really was a path, and not a chance formation. The opposite ledge had constantly receded until it was now some thirty feet distant. The path upon which he stood had narrowed until it was scarcely over eighteen inches wide at this spot. There was one other possibility: the ledge at this point might have crumbled and fallen. In his progress he had loosened many stones which rattled downwards out of hearing.
He secured a good balance on his left foot and cautiously lowered the other. Inch by inch he groped down keeping his arms as far outstretched as possible. Finally his toe touched something solid. He ventured an inch farther at the risk of losing his balance. He found a more secure footing and, taking a chance, rested his full weight. The base was firm and he drew down the other foot. He was on a wider path than that above. He paused here for the effort had made his breath come short. It was more the mental 251 than the physical strain which had weakened him. It was nerve-racking work. The dark and the silence oppressed him. There was almost a tomb-like effect in this slit of the earth where man had not been for centuries. Once he had ventured to shout to Stubbs but his voice had sounded so muffled and the effort had produced in him such a panicky feeling that he did not try it again.
Once more he shuffled forward and once more his foot dangled over nothing. But he had gained more confidence now and lowered it to find another firm base. Two more steps came after this, and then the path proceeded on the level once more. He had gone some forty paces on this last lap when he was brought up against a face of solid rock. He moved his hands over it as far as possible in every direction, but he could not detect any boundaries. It appeared to be a part of the cliff itself. But once more he recalled the warning, “The seeming is not always the true.” Then he tried to recall the details of the directions. His map was about his neck but he was in such a position that it would be hazardous to attempt to reach it. In spite of the many times he had read it, he could not now remember a word. The more he tried, the more confused he became.
After all, he had gone farther than he had intended. The thought of returning came as a relief. The next time he would have more confidence and could proceed with less of a strain. And so, step by step, he began to retrace the path. He was forced to keep his cheek 252 almost flat to the rock. The dry dust sifted into his nostrils and peppered his eyes so that he was beginning to suffer acutely from the inflammation. His arms, too, began to pain him as he had been unable to relieve them at all from their awkward position. The last fifty feet were accomplished in an agony that left him almost too weak to raise his voice. But he braced himself and shouted. He received no response. He lifted his head and reached up an aching arm for the sleeve which he had left dangling over the cliff. It was not there. With a sinking heart he realized that something must have happened to Stubbs. The coats had probably fallen into the chasm below.
CHAPTER XXI
The Hidden Cave
In the face of this new emergency Wilson, as a real man will, quickly regained control of himself. Some power within forced his aching body to its needs. The first shock had been similar to that which a diver feels when receiving no response to a tug upon the life line. He felt like a unit suddenly hurled against the universe. Every possible human help was removed, bringing him face to face with basic forces. His brain cleared, his swollen and inflamed eyes came to their own, and his aching arms recovered their strength. The fresh shock had thrown these manifestations so far into the background of his consciousness that they were unable to assert themselves.
