Thus devising his revenge he determined to act at once. Taking two of his men with him he rode up by the edge of 'the Waste' towards Coplestone Fell, with intent to capture Si, or, should he evade capture, to leave a citation at 'the Bower' for his appearance at the next meeting of the Lord Wardens on account of notorious breakage of the Border law. But Si had already been made aware of his enemy's intention, and had instructed Meg how to act in such an emergency, for it might well be that trouble would come when he was out looking after a 'hogging' he had of 'blackfaces' that were pasturing above the Forks, where the Lewis Burn and Oakenshaw Burn mate. The season of the foray had opened and flocks must be guarded by day and night. One afternoon when Si had ridden down to the Forks to relieve Dand, Meg stood by the 'yett,' expectant of the old shepherd's return, and watchful of enemies. As she turned her gaze southward she was suddenly aware of three figures clearly tricked out against the grey sky above the further fell: their silhouettes showed like midges dapped against the window by a boy, and Meg could see that the centaurs were coming forward on a fair round trot in Indian file. She could not distinguish at the distance horse from rider, but she could note the pose of the horse's head, and the movement against the sky-line. 'Three-quarters of an hour,' commented the gazer. 'Good going on the fell top, evil wi' peat hags, flows, an' gairs below.' She looked eastward, and there saw to her infinite relief old Dand coming slowly up the track on the ancient pony. Then, after having gone within to make certain preparations, she set out on a brisk step to meet Dand. Dand had quickened his pace when he too saw the three black silhouettes above, and met his mistress within two yards of the dry-stone walling. A very animated conversation took place between the two, and by the time they reached the door cheeks of 'the Bower' they seemed to have settled their scheme of strategy satisfactorily, for either turned away from other with a wink o' the eye. The strange riders had dismounted and walked their horses through the peat hags and mosses, but now were up again, and pressing on to the 'yett.' The foremost rider--the Land Sergeant--knocked heavily on the door with the butt of his lance and demanded to see 'Robson o' the Bower i' the name o' my Lord Warden.' 'He's no' within,' cried Meg in return. 'Whatten want ye at him?' Then she slowly slid back the bar, and, opening the door partly, stood in the space thus afforded, her hands upon her hip bones.
