He raised her again in his arms and strode once more out through the covert into the dim aisles of the wood. They spoke but little; she could not help feeling that some other discordant element, affecting him more strongly than it did her, had come between them, and was half perplexed and half frightened. At the end of ten minutes he seated her upon a fallen branch, and telling her he would return by the time she had resumed her shoes and stockings glided from her like a shadow. She would have uttered an indignant protest at being left alone, but he was gone ere she could detain him. For a moment she thought she hated him. But when she had mechanically shod herself once more, not without nervous shivers at every falling needle, he was at her side. "Do you know any one who wears a frieze coat like that?" he asked, handing her a few torn shreds of wool affixed to a splinter of bark. Miss Nellie instantly recognized the material of a certain sporting-coat worn by Mr. Jack Brace on festive occasions, but a strange yet infallible instinct that was part of her nature made her instantly disclaim all knowledge of it. "No," she said. "Not any one who scents himself with some doctor's stuff like cologne?" continued Low, with the disgust of keen olfactory sensibilities. Again Miss Nellie recognized the perfume with which the gallant expressman was wont to make redolent her little parlor, but again she avowed no knowledge of its possessor. "Well," returned Low, with some disappointment, "such a man has been here. Be on your guard. Let us go at once." She required no urging to hasten her steps, but hurried breathlessly at his side. He had taken a new trail by which they left the wood at right angles with the highway, two miles away. Following an almost effaced mule track along a slight depression of the plain, deep enough, however, to hide them from view, he accompanied her, until, rising to the level again, she saw they were beginning to approach the highway and the distant roofs of Indian Spring. "Nobody meeting you now," he whispered, "would suspect where you had been. Good night! until next week--remember." They pressed each other's hands, and standing on the slight ridge outlined against the paling sky, in full view of the highway, parting carelessly, as if they had been chance met travellers. But Nellie could not restrain a parting backward glance as she left the ridge. Low had descended to the deserted trail, and was running swiftly in the direction of the Carquinez Woods. CHAPTER IV.
