Quick as lightning he faced round, snatching at his assailant; but Louie was off, scudding among the bilberry hillocks with peals of laughter, while the slimy moss she had just gathered from the edges of the brook sent cold creeping streams into the recesses of David's neck and shoulders. He shook himself free of the mess as best he could, and rushed after her. For a long time he chased her in vain, then her foot tripped, and he came up with her just as she rolled into the heather, gathered up like a hedgehog against attack, her old hat held down over her ears and face. David fell upon her and chastised her; but his fisticuffs probably looked more formidable than they felt, for Louie laughed provokingly all the time, and when he stopped out of breath she said exultantly, as she sprang up, holding her skirts round her ready for another flight, 'It's greened aw yur neck and yur collar--luvely! Doan't yo be nassty for nothink next time!' And off she ran. 'If yo meddle wi me ony moor,' he shouted after her fiercely, 'yo see what I'll do!' But in reality the male was helpless, as usual. He went ruefully down to the brook, and loosening his shirt and coat tried to clean his neck and hair. Then, extremely sticky and uncomfortable, he went back to his seat and his book, his wrathful eyes taking careful note meanwhile of Louie's whereabouts. And thenceforward he read, as it were, on guard, looking up every other minute. Louie established herself some way up the further slope, in a steep stony nook, under two black boulders, which protected her rear in case of reprisals from David. Time passed away. David, on the other side of the brook, revelling in the joys of battle, and all the more alive to them perhaps because of the watch kept on Louie by one section of his brain, was conscious of no length in the minutes. But Louie's mood gradually became one of extreme flatness. All her resources were for the moment at an end. She could think of no fresh torment for David; besides, she knew that she was observed. She had destroyed all the scanty store of primroses along the brook; gathered rushes, begun to plait them, and thrown them away; she had found a grouse's nest among the dead fern, and, contrary to the most solemn injunctions of uncle and keeper, enforced by the direst threats, had purloined and broken an egg; and still dinner-time delayed. Perhaps, too, the cold blighting wind, which soon made her look blue and pinched, tamed her insensibly. At any rate, she got up after about an hour, and coolly walked across to David. He looked up at her with a quick frown. But she sat down, and, clasping her hands round her knees, while the primroses she had stuck in her hat dangled over her defiant eyes, she looked at him with a grinning composure. 'Yo can read out if yo want to,' she remarked. 'Yo doan't deserve nowt, an I shan't,' said David, shortly. 'Then I'll tell Aunt Hannah about how yo let t' lambs stray lasst evenin, and about yor readin at neet.'
