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.
