A new experience had come to the little wolf cubs in a single night,—the experience of fear. For weeks they had lain hid in the dark den, or played fearlessly in the bright sunshine, guarded and kept at every moment, day or night, by the gaunt old mother wolf that was their only law, their only companion. At times they lay for hours hungry and restless, longing to go out into the bright world, yet obeying a stronger will than their own, even at a distance. For, once a wild mother in her own dumb way has bidden her little ones lie still, they rarely stir from the spot, refusing even to be dragged away from the nest or den, knowing well the punishment in store if she return and find them absent. Moreover, it is useless to dissimulate, to go out and play and then to be sleeping innocently with the cubs when the old wolf's shadow darkens the entrance. No concealment is possible from wolf's nose; before she enters the den the mother knows perfectly all that has happened since she went away. So the days glided by peacefully between sleep and play, the cubs trusting absolutely in the strength and tenderness that watched over them, the mother building the cubs' future on the foundation of the two instincts which are strong in every wild creature born into a world of danger,—the instinct to lie still and let nature's coloring hide all defenseless little ones, and the instinct to obey instantly a stronger will than their own.

There was no fear as yet, only instinctive wariness; for fear comes largely from others' example, from alarms and excitement and cries of danger, which only the grown animals understand. The old wolf had been undisturbed; no dog or hunter had chased her; no trap or pitfall had entangled her swift feet. Moreover, she had chosen her den well, where no man had ever stood, and where only the eyes of two children had seen her at a distance. So the little ones grew and played in the sunshine, and had yet to learn what fear meant.

One day at dusk the mother entered swiftly and, without giving them food as she had always done, seized a cub and disappeared. For the little one, which had never before ventured beyond sight of the den, it was a long journey indeed that followed,—miles and miles beside roaring brooks and mist-filled ravines, through gloomy woods where no light entered, and over bare ridges where the big stars sparkled just over his ears as he hung, limp as a rabbit skin, from his mother's great jaws. An owl hooted dismally, whoo-hooo! and though he knew the sound well in his peaceful nights, it brought now a certain shiver. The wind went sniffing suspiciously among the spruce branches; a startled bird chirped and whirred away out of their path; the brook roared among the rocks; a big salmon jumped and tumbled back with resounding splash, and jumped again as if the otter were after him. There was a sudden sharp cry, the first and last voice of a hare when the weasel rises up in front of him; then silence, and the fitful rustle of his mother's pads moving steadily, swiftly over dry leaves. And all these sounds of the wilderness night spoke to the little cub of some new thing, of swift feet that follow and of something unknown and terrible that waits for all unwary wild things. So fear was born.

The long journey ended at last before a dark hole in the hillside; and the smell of his mother, the only familiar thing in his first strange pilgrimage, greeted the cub from the rocks on either side as he passed in out of the starlight. He was dropped without a sound in a larger den, on some fresh-gathered leaves and dead grass, and lay there all alone, very still, with the new feeling trembling all over him. A long hour passed; a second cub was laid beside him, and the mother vanished as before; another hour, and the wolf cubs were all together again with the mother feeding them. Nor did any of them know where they were, nor why they had come, nor the long, long way that led back to where the trail began.

Next day when they were called out to play they saw a different and more gloomy landscape, a chaos of granite rocks, a forest of evergreen, the white plunge and rolling mist of a mountain torrent; but no silver sea with fishing-boats drifting over it, like clouds in the sea over their heads, and no gray hut with children running about like ants on the distant shore. And as they played they began for the first time to imitate the old mother keeping guard over them, sitting up often to watch and listen and sift the winds, trying to understand what fear was, and why they had been taken away from the sunny hillside where the world was so much bigger and brighter than here. But home is where mother is,—that, fortunately, is also true of the little Wood Folk, who understand it in their own savage way for a season,—and in their wonder at their new surroundings the memory of the old home gradually faded away. They never knew with what endless care the new den had been chosen; how the mother, in the days when she knew she was watched, had searched it out and watched over it and put her nose to every ridge and ravine and brook-side, day after day, till she was sure that no foot save that of the wild things had touched the soil within miles of the place. They felt only a greater wildness, a deeper solitude; and they never forgot, though they were unmolested, the strange feeling that was born in them on that first terrifying night journey in their mother's jaws.

Soon the food that was brought home at dawn—the rabbit or grouse, or the bunch of rats hanging by their tails, with which the mother supplemented their midday drink of milk—became altogether too scant to satisfy their clamorous appetites; and in the bright afternoons and the long summer twilights the mother led them forth on short journeys to hunt for themselves. No big caribou or cunning fox cub, as one might suppose, but "rats and mice and such small deer" were the limit of the mother's ambition for her little ones. They began on stupid grubs that one could find asleep under stones and roots, and then on beetles that scrambled away briskly at the first alarm, and then, when the sunshine was brightest, on grasshoppers,—lively, wary fellows that zipped and buzzed away just when you were sure you had them, and that generally landed from an astounding jump facing in a different direction, like a flea, so as to be ready for your next move.

It was astonishing how quickly the cubs learned that game is not to be picked up tamely, like huckleberries, and changed their style of hunting,—creeping, instead of trotting openly so that even a porcupine must notice them, hiding behind rocks and bushes and tufts of grass till the precise moment came, and then leaping with the swoop of a goshawk on a ptarmigan. A wolf that cannot catch a grasshopper has no business hunting rabbits—this seemed to be the unconscious motive that led the old mother, every sunny afternoon, to ignore the thickets where game was hiding plentifully and take her cubs to the dry, sunny plains on the edge of the caribou barrens. There for hours at a time they hunted elusive grasshoppers, rushing helter-skelter over the dry moss, leaping up to strike at the flying game with their paws like a kitten, or snapping wildly to catch it in their mouths and coming down with a back-breaking wriggle to keep themselves from tumbling over on their heads. Then on again, with a droll expression and noses sharpened like exclamation points, to find another grasshopper.

Small business indeed and often ludicrous, this playing at grasshopper hunting. So it seems to us; so also, perhaps, to the wise old mother, which knew all the ways of game, from crickets to caribou and from ground sparrows to wild geese. But play is the first great educator,—that is as true of animals as of men,—and to the cubs their rough helter-skelter after hoppers was as exciting as a stag hunt to the pack, as full of surprises as the wild chase through the soft snow after a litter of lynx kittens. And though they knew it not, they were learning things every hour of the sunny, playful afternoons that they would remember and find useful all the days of their life.

So the funny little hunt went on, the mother watching gravely under a bush where she was inconspicuous, and the cubs, full of zest and inexperience, missing the flying tidbits more often than they swallowed them, until they learned at last to locate all game accurately before chasing or alarming it; and that is the rule, learned from hunting grasshoppers, which a wolf follows ever afterward. Even after they knew just where the grasshopper was hiding, watching them after a jump, and leaped upon him swiftly from a distance, he often got away when they lifted their paws to eat him. For the grasshopper was not dead under the light paw, as they supposed, but only pressed into the moss waiting for his chance to jump. Then the cubs learned another lesson: to hold their game down with both paws pressed closely together, inserting their noses like a wedge and keeping every crack of escape shut tight until they had the slippery morsel safe under their back teeth. And even then it was deliciously funny to watch their expression as they chewed, opening their jaws wide as if swallowing a rabbit, snapping them shut again as the grasshopper wiggled; and always with a doubt in their close-set eyes, a questioning twist of head and ears, as if they were not quite sure whether or not they were really eating him.
