Hands were laid on him and the roughness with which he was moved sent Ross spiraling back into the dark once again. When he aroused for the second time it was night and the pain in his head was dulled. He put out his hands and discovered that he lay on a pile of fur robes, and was covered by one. "Assha--" Again he tried that name. But it was not Assha who came in answer to his feeble call. The woman who knelt beside him with a horn cup in her hand had neatly braided hair in which gray strands showed silver by firelight. Ross knew he had seen her before, but again where and when eluded him. She slipped a sturdy arm under his head and raised him while the world whirled about. The edge of the horn cup was pressed to his lips, and he drank bitter stuff which burned in his throat and lit a fire in his insides. Then he was left to himself once again and in spite of his pain and bewilderment he slept. How many days he lay in the camp of Ulffa, tended by the chief's head wife, Ross found it hard to reckon. It was Frigga who had argued the tribe into caring for a man they believed almost dead when they found him, and who nursed Ross back to life with knowledge acquired through half a hundred exchanges between those wise women who were the doctors and priestesses of these roaming peoples. Why Frigga had bothered with the injured stranger at all Ross learned when he was able to sit up and marshal his bewildered thoughts into some sort of order. The matriarch of the tribe thirsted for knowledge. That same urge which had led her to certain experiments with herbs, had made her consider Ross a challenge to her healing skill. When she knew that he would live she determined to learn from him all he had to give. Ulffa and the men of the tribe might have eyed the metal weapons of the traders with awe and avid desire, but Frigga wanted more than trade goods. She wanted the secret of the making of such cloth as the strangers wore, everything she could learn of their lives and the lands through which they had come. She plied Ross with endless questions which he answered as best he could, for he lay in an odd dreamy state where only the present had any reality. The past was dim and far away, and while he was now and then dimly aware that he had something to do, he forgot it easily. The chief and his men prowled the half-built station after the attackers had withdrawn, bringing back with them a handful of loot--a bronze razor, two skinning knives, some fishhooks, a length of cloth which Frigga appropriated. Ross eyed this spoil indifferently, making no claim upon it. His interest in everything about him was often blanked out by headaches which kept him limp on his bed, uncaring and stupid for hours or even full days. He gathered that the tribe had been living in fear of an attack from the same raiders who had wiped out the trading post. But at last their scouts returned with the information that the enemy had gone south.
