There was, however, a reason for the failure of the young hunters beyond lack of skill and what they called their ill-luck. Hector of the Stags was awake; his keen, everywhere-roving eyes were upon them, seconded by the keen, all-hearkening ears of Bob of the Angels. They had discovered that the two men had set their hearts on the big stag, an cabrach mor by right of excellence, and every time they were out after him, Hector too was out with his spy-glass, the gift of an old sea-faring friend, searching the billowy hills. While, the southrons would be toiling along to get the wind of him unseen, for the old stag's eyes were as keen as his velvety nose, the father and son would be lying, perhaps close at hand, perhaps far away on some hill-side of another valley, watching now the hunters, now the stag. For love of the Macruadh, and for love of the stag, they had constituted themselves his guardians. Again and again when one of them thought he was going to have a splendid chance--perhaps just as, having reached a rock to which he had been making his weary way over stones and bogs like Satan through chaos, and raised himself with weary slowness, he peeped at last over the top, and lo, there he was, well within range, quietly feeding, nought between the great pumping of his big joyous heart and the hot bullet but the brown skin behind his left shoulder!--a distant shot would forestall the nigh one, a shot for life, not death, and the stag, knowing instantly by wondrous combination of sense and judgment in what quarter lay the danger, would, without once looking round, measure straight a hundred yards of hillocks and rocks between the sight-taking and the pulling of the trigger. Another time it would be no shot, but the bark of a dog, the cry of a moorfowl, or a signal from watching hind that started him; for the creatures understand each the other's cries, and when an animal sees one of any sort on the watch to warn covey or herd or flock of its own kind, it will itself keep no watch, but feed in security. To Christian and Sercombe it seemed as if all the life in the glen were in conspiracy to frustrate their hearts' desire; and the latter at least grew ever the more determined to kill the great stag: he had begun to hate him.
