He looked along the cleft from the narrow inner end to the wider outer end, and there noticed a long dark object lying transversely across it. He thought at first that it was possibly a sapling which had been uprooted and fallen, but this idea was negatived on his approaching the spot. The object lay, not on top of the cliff on either side, but a foot or two below. Walking, still with caution, close up to the place, he was surprised to find that the two sides of the cleft were connected by a stout bar of iron, the nearer end of which he felt was firmly embedded in the rock, reminding him of similar poles used at home to support unsteady arches or prop up tottering houses. Obviously no such purpose could have been intended for this bar, and he vaguely wondered why and when it had been placed in position. It had clearly been there a long time; it was much rusted, flakes of rust coming off as he touched it.
Leaving the cleft, he returned as quickly as possible to the spot where he had left Ah-Sam and the chief. The former rose to meet him.
"Well," said Bob, "has all been quiet?"
"Yes, massa; no piecee man come this-side, no bobbely, not'ing."
"I want you to come along with me. Hide your baskets under the shrubs, but bring the straps; we may require them."
In a few moments he was leading the way in a direction at an angle to the path he had taken, past the narrow end of the cleft, and then on a line parallel with the edge of the ravine. He walked for nearly a mile, finding as he proceeded that the ground, while undulating, was in general on almost the same level as his starting-place. Suddenly, however, it made a sharp dip, and going to the edge of the ravine he saw that the cliffs on both sides were less precipitous and less lofty. The sky had for some time been growing lighter, indicating the rising of the moon; and peering over the edge he saw the water of the torrent sweeping along in foamy current below. The sides of the ravine were covered with stunted trees, by means of which he saw that descent or ascent might be facilitated. Telling Ah-Sam to join the three straps together, he took one end and climbed down the rocky slope, carefully placing his feet, and stopping at intervals to allow the men to make sure their footing behind him. Having reached the brink of the stream, he bade his followers remain hidden among the trees; then he waded into the water, and began to ascend the opposite side, carrying the strap with him to assist in his descent by and by.
The moon, emerging now and then from among the flying clouds, threw a fitful radiance over the scene as Bob scrambled up the steep acclivity. Stepping with great care, pulling himself up by overhanging branches after he had tested them, endeavouring not to displace loose stones, he at last with one final heave gained the top, where he sat down to recover breath and look around him. The white moonlight clothed the neighbourhood with a ghostly glamour, throwing up in bold relief the grim outlines of the fort far up the ravine. No tree or other obstacle interposed between it and him; the ground for some distance from the edge had probably been kept bare purposely. But some hundred and fifty yards to his left there stood a dark patch of firs, he could not tell of what extent; to gain that would at any rate bring him a little nearer to the fort. Throwing himself on his face, he crawled towards it, pausing every few moments to listen. It seemed a long time before he reached the firs: it was really only a few minutes; but at last he gained their shelter, and stood erect, stretching himself in relief.
A light wind sighed in notes of gentle melancholy among the branches, though above his head he saw between the tree-tops the heavy clouds drifting rapidly across the sky. He moved carefully among the firs, pausing now and then to listen and to take his bearings, for he was anxious to avoid the risk of losing his way as he returned. The trees at the edge of the clump were set far apart, and between their trunks he saw three firs forming a group on the other side of the ravine. These he took as his landmark. Then he walked into the heart of the patch, where the trees grew thicker, treading lightly on the deep compost of fir cones, wondering whither his steps were leading him.
Suddenly he halted. A faint sound had touched his ears from a point ahead—a sound like the clink of steel. He listened, his body bent forward resting on his right foot, his left foot raised upon its toes. The sound had ceased; he now heard nothing but the rustle of the wind. He went on again, but after a few steps he was again arrested by the same sound, the same slight clink. Again he waited, for a longer time. Hearing nothing, he took a few more steps, and emerged almost unawares upon a small clear space. Instantly he darted on tiptoe behind the nearest trunk. In the centre of the clearing a figure had caught his eye, a motionless form whose outlines in the suddenness of its discovery he had had no time to distinguish. He waited, scarcely daring to breathe; his heart thumped against his ribs, he heard its thuds. But there was no sound from before him—yes, he caught again the clink-clink, louder, more prolonged.
He waited, then ventured to peep out from behind the trunk. The figure was still there, in the same spot, in the same attitude, motionless. Strain his eyes as he might, Bob could detect, in the darkness of an overshadowing cloud, no sign of movement. A gust of wind came sighing through the copse; yes, the figure does move, and as it moves there comes again the clink-clink. Then all is still again. A nameless uneasiness seized upon Bob; a cold, clammy perspiration broke from every pore; he watched the figure as if fascinated. Again a gust of wind; again the slight swaying movement; again the soft clink-clink; again the perfect stillness.
