"I think I can give you food," he said. "It is permitted to give food, is it not?" he asked his comrades; and when they nodded, he opened his knapsack and took out a package of hard, square biscuits and a thick roll of sausage. He cut the sausage into generous slices, while Stewart watched with watering mouth, placed a slice on each of the biscuits, and passed them over. "Splendid!" cried Stewart. "I don't know how to thank you. But at least I can pay you," and he dove into his pocket and produced a ten-mark piece--his last. The soldier shook his head. "It is for the whole squad," added Stewart, persuasively. "You will be needing tobacco some day, and this will come in handy!" The soldier smiled, took the little coin, and placed it carefully in his pocket. "You are right about the tobacco," he said. "I thank you." He sat down again before the fire, while Stewart hastened to his companion and dropped to his knees beside her. "See what I've got!" he cried. "Food!" She opened her eyes, struggled to a sitting posture, and held out an eager hand. A moment later, they were both munching the sausage and biscuits as though they had never tasted anything so delicious--as, indeed, they never had! "Oh, how good that was!" she said, when the last crumb was swallowed, and she waved her thanks to the watching group about the fire. "Remember," she added, in a lower tone, as she sank back upon her elbow, "the instant----" She stopped, staring toward the tunnel, one hand grasping the blanket. Stewart, following her look, saw the sentry stiffen, turn on his heel, and hold his rifle rigidly in front of him, as a tall figure, clad in a long gray coat and carrying an electric torch, stepped out of the darkness of the tunnel. At the same instant, the men about the fire sprang to their feet. "Now!" cried the girl, and threw back the blanket. In an instant, hand in hand, they had glided into the darkness. CHAPTER XI THE NIGHT ATTACK A savage voice behind them shouted, "Halt!" and then a bullet sang past and a rifle went off with a noise like a cannon--or so it seemed to Stewart; then another and another. It was the sentry, of course, pumping bullets after them. Stewart's flesh crept at the thought that any instant might bring a volley, which would sweep the track with a storm of lead. If he could only look back, if he only knew---- Suddenly the girl pulled him to the right, and he saw there was a cleft in the steep bank. Even as they sprang into it, the volley came, and then a second and a third, and then the sound of shouting voices and running feet.
