"Yes. Yes," she muttered. "But you are very young." Then she asked in a hesitating way: "Will you not sit down until I do?" "No," answered Marco. "I would not sit while my mother or grandmother stood." "Then I must sit--and forget," she said. She passed her hand over her face as though she were sweeping away the sudden puzzled trouble in her expression. Then she sat down, as if she had obliged herself to become again the old peasant she had been when they entered. "All the way up the mountain you wondered why an old woman should be given the Sign," she said. "You asked each other how she could be of use." Neither Marco nor The Rat said anything. "When I was young and fresh," she went on. "I went to a castle over the frontier to be foster-mother to a child who was born a great noble--one who was near the throne. He loved me and I loved him. He was a strong child and he grew up a great hunter and climber. When he was not ten years old, my man taught him to climb. He always loved these mountains better than his own. He comes to see me as if he were only a young mountaineer. He sleeps in the room there," with a gesture over her shoulder into the darkness. "He has great power and, if he chooses to do a thing, he will do it--just as he will attack the biggest bear or climb the most dangerous peak. He is one who can bring things about. It is very safe to talk in this room." Then all was quite clear. Marco and The Rat understood. No more was said about the Sign. It had been given and that was enough. The old woman told them that they must sleep in one of her bedrooms. The next morning one of her neighbors was going down to the valley with a cart and he would help them on their way. The Rat knew that she was thinking of his crutches and he became restless. "Tell her," he said to Marco, "how I have trained myself until I can do what any one else can. And tell her I am growing stronger every day. Tell her I'll show her what I can do. Your father wouldn't have let me come as your aide if I hadn't proved to him that I wasn't a cripple. Tell her. She thinks I'm no use." Marco explained and the old woman listened attentively. When The Rat got up and swung himself about up and down the steep path near her house she seemed relieved. His extraordinary dexterity and firm swiftness evidently amazed her and gave her a confidence she had not felt at first. "If he has taught himself to be like that just for love of your father, he will go to the end," she said. "It is more than one could believe, that a pair of crutches could do such things."
