The struggle went on in silence, as far as the voices of both combatants were concerned. But the beating of the hawk's wings resounded on the glassy-hard surface of the snow. As the struggle shifted ground, those flapping wings came suddenly in contact with a bush, whose iced twigs were brittle as glass and glittering like the prisms of a great crystal candelabrum. There was a shrill crash and a thin, ringing clatter as the twigs shattered off and spun flying across the crust. The sound carried far through the still iridescent spaces of the wilderness. It reached the ears of a foraging fox, who was tiptoeing with dainty care over the slippery crust. He turned hopefully to investigate, trusting to get a needed breakfast out of some fellow-marauder's difficulties. At the edge of the glade he paused, peering through a bush of crystal fire to size up the situation before committing himself to the venture. Desperately preoccupied though she was, the hawk's all-seeing eyes detected the red outlines of the fox through the bush. With a frantic beating of her wings she lifted herself from the snow. The fox darted upon her with a lightning rush and a shattering of icicles. He was just too late. The great bird was already in the air, carrying her deadly burden with her. The fox leapt straight upwards, hoping to pull her down, but his clashing jaws just failed to reach her talons. Labouring heavily in her flight, she made off, striving to gain a tree-top, where she might perch and once more give her attention to the gnawing torment which clung beneath her wing. The fox, being wise, and seeing that the hawk was in extremest straits, ran on beneath her as she flew, gazing upwards expectantly. The weasel, meanwhile, with that deadly concentration of purpose which characterizes his tribe, paid no heed to the fact that he was journeying through the air. And he knew nothing of what was going on below. His flaming eyes were buried in his foe's feathers, his jaws were steadily working inwards toward her vitals. Just at the edge of the glade, immediately over the top of a branchy young paper-birch which shot a million coloured points of light in the sunrise, the end came. The fangs of the weasel met in the hawk's wildly throbbing heart. With a choking burst of scarlet blood it stopped. Stone dead, the great marauder of the air crashed down through the slim birch-top, with a great scattering of gleams and crystals. With wide-sprawled wings she thudded down upon the snow-crust, almost under the fox's complacent jaws. The weasel's venomous head, covered with blood, emerged triumphant from the mass of feathers.
