Pausing a moment, he scanned the sky above him for a bright star by which to set his course, then set off again, counting his paces. In daylight he had estimated that the summit of the hill was nearly half a mile in a straight line from the mouth of the gully; the distance would be greater over the uneven ground, and still greater from his starting-point. Every now and then he stopped to listen and look round. When he had counted some three hundred paces, the source of the glow at last became visible. On his left there were two fires some distance apart, with a few men moving about them, standing out for a moment black against the glow, then appearing red as they passed to the side, then vanishing altogether. From the position of the fires Bob guessed that they stood just under the hillside on the far side of the gully. There could be no doubt that they marked the site of the enemy's camp; and they were so near the barricade that if the besieged ventured to make a sortie they would not only have to reckon with the force on duty at the mouth of the gully, but also with a flank attack from the main body encamped a few yards away.

In the darkness it was impossible for Bob to tell when he had reached the summit of the hill. But he stopped at intervals to look back, and when he found that first one then the other fire gradually disappeared from sight, he judged that between them and him the brow of the hill intervened. At this point it was necessary to take another star as his guide. Turning now to the left, almost at right angles with his former course, he plodded warily on, skirting the hill not far from the summit, the fires appearing and disappearing with the inequalities of the crest. Though he kept eyes and ears keenly alert for sound or sight of the enemy, he neither heard nor saw any trace of them except at the camp fires. Continuing his course as nearly straight as he could, he came at length opposite the farthermost fire; then he turned again to the left, and moving with still greater caution, he made straight towards it. He was now descending a gradual slope. The fire was burning low; backed by the slope he thought he might venture still nearer; so, dropping on all-fours, he crawled for some distance over the ground, sodden with melted snow, until he stopped at length within some eighty yards of the fire. A little in front of him he heard the gurgling of the stream from the gully running across the face of the two camps. In the dim glow he saw by their dress that the occupants of the camp opposite him were Cossacks; the other camp was clearly that of the Manchus. He threw a glance round the position; a little in advance of him, to the right, he descried a number of dark forms, which he soon concluded were the picketed horses of the enemy. Two sentries were on duty, walking to and fro some forty yards from the outermost row of tents, and meeting about the middle of the exposed face of the camp. Beyond, Bob caught a glimpse of the figure of a Manchu patrolling in the same way opposite his camp. The Manchus' horses were not at the moment in sight, but a sudden replenishment of the fire caused a bright flame to spring up, making Bob lie absolutely motionless and almost hold his breath, at the same time throwing up the figures of the horses tethered just under the hill.

He had now learnt all that was possible about the enemy's position. As soon as the fire had died down again he might retrace his steps. He lay still on his face, waiting, letting his eyes range at random, when suddenly he gave a violent start. A little to the left of the horses, beside a tall bare sapling, stood a man whom he perceived, as he looked more closely, to be bound to the stem. He wore the dress of a Chinaman. The fitful flame from the Manchus' fire cast a lurid light upon the face of the prisoner, and with a feeling of dismay Bob recognized him: it was Kobo!

It flashed upon him at once: this was the prisoner he had seen among the fresh band of Manchus that morning. Kobo had been captured at last. His doom was sealed—unless he could be rescued. Bob almost sprang up in his excitement. How could he make his presence known to his friend? By his bearing he saw that he was awake. If he could communicate with him perhaps some means of effecting his escape would offer. Kobo had dared much for him—to Kobo he owed his own escape from the spy's fate; how eagerly would he do something in return for Kobo!

He lay watching, thinking, hoping that by some lucky chance he might be enabled to approach the prisoner. He dared not move. The minutes flew by, the fire was sinking; in a few moments it would again be replenished, and his position again be imperilled. He saw not the shadow of an opportunity of assisting Kobo. For the present he must give up the idea. Crawling back slowly and stealthily he reached a point where it would be safe to rise. Then, finding the star by which he had steered his course, he made his way toilsomely, reluctantly, up the hill again.

This time he took a shorter circuit inside his first track, and on the nearer slope of the hill, until he came to a spot which he thought must be opposite the opening of the cleft. But how could he make sure? If he swerved too far to the right and blundered upon the breastwork at the entrance to the gully his life was not worth a moment's purchase, and the safety of his party would be fatally jeopardized. Pausing in his incertitude, he bethought him of the fact that the enemy's watch-fires might be used to determine his rightful course. So long as they were out of sight, obviously he would be in no danger of coming upon the breastwork, though he might find himself perilously near it if he happened to hit the spur at the mouth of the gully. Fetching a wider circuit he abruptly altered his direction, looking anxiously at the fires in the hope that they would by and by be concealed from him by the prominent spur. It was a long time before either disappeared, and more than once he feared lest, after all, he had turned too early to the right. But at length first one, then the other, was hidden from his view, and against the penumbra of their glow the spur stood out dark upon his right. He gave a sigh of relief, and stopped for a moment to wipe the perspiration from his brow.

He steered now towards a point somewhat to the left of the bluff's jagged outline, until he came close beneath it. Then he turned sharp to the left, to find the slope up which he must climb to reach the fissure. For some minutes he stumbled about. The night was darker than ever, but he knew that his general direction was right, for the ground became rougher and the loose stones more numerous. At last, close at hand, he recognized the tall twin rocks imprisoning the bear. Swarming up the steep slope on hands and knees, he came to the top, and stretched out his right hand, moving it from side to side to feel for the dangling rope. He touched it, caught it, gave it a gentle tug. He felt it tighten. Ah-Sam had faithfully remained at his post above. Then with straining muscles he scrambled up; he reached the fissure and Ah-Sam's welcoming hands.

"My tinkey Roshians hab catchee," said the Chinaman.

"Not yet, Ah-Sam. Pull up the rope, then follow me back to the ladies."

Soon darkness and silence brooded upon the rugged hillside. The blinking stars saw nothing; no sound broke the stillness save when at midnight a hungry wolf came padding to the foot of the slope, and snarled as he fixed his fangs in the carcase of the bear.
