Hunger drove the creatures forth, and by evening the snow was interlaced with their innumerable trails. The bigger lynx emerged from his dark den high up under an overhanging ledge, stretched himself and yawned mightily, then set off in search of a meal. For a long time he was unsuccessful. The creatures were shy and frightened by their own shadows upon this white coverlet which made the night woods almost as light as day. The lynx was obliged to be content with a rabbit caught at the edge of a snow drift, though his fierce appetite craved stronger food. Weeks passed and the plight of the forest creatures grew steadily worse. Icy gales swept down from the far north, following each other in rapid succession and making it impossible for any forest creature to stir abroad, sometimes for days at a time. The lynxes grew steadily leaner and their temper more savage. Like gaunt shadows of doom they drifted down the snowy aisles of the forest, now and then coming upon a grouse, which had burrowed into a drift for the night, only to find itself imprisoned by the freezing of the crust above. Even wood mice were difficult to obtain, though their runways branched everywhere deep down under the snow, which to them was a blessing. The nights were cold and still, lit by the great fan of the Aurora Borealis which pulsed upward to the zenith, glowing with its ever-changing colors--delicate green fading into violet and blue, flaming redly or dying away in a pure white light. About this time the female lynx met her fate in an encounter with a fat porcupine who dawdled across her trail. The sight of good eating so tantalizingly near caused her to lose all caution. With her long claws she endeavored to turn the porcupine over that she might reach his unprotected under parts. In her eagerness, however, she forgot the barbed tail which dealt her a smashing blow, full in the face. One of the quills mercifully penetrated the brain and at once put an end to the painful struggles. Thus the male lynx was left to walk the trails alone, but in spite of the odds against him, he succeeded in holding his own. The beginning of March saw no break in the intense cold. In fact, March in the wilderness is the most bitter month of the winter. Food is reduced to a minimum and the survivors of cold and hunger are exceedingly wary. One night when the moon, far off in a cloudless sky, sent pale fingers of mysterious light creeping down the dark forest lanes, the surviving lynx appeared in his endless search for food, his huge pads making no sound as he kept himself cunningly concealed among the shifting shadows. The hush of death brooded over the frozen forest, a hush in which the scratching of a dry leaf across the icy snow crust could be plainly heard for some distance. Occasionally the silence was broken by a loud report from some great tree.
