Yet if the chance did come, if the house should be left unguarded, it might play Cranston to make an immediate search. Dan would have no reason for supposing that Cranston suspected his possession of the letters; he would not be particularly watchful, and would probably pigeonhole them until spring in Lennox's desk.

And the truth was that Cranston had reasoned out the situation almost perfectly. When Dan wakened in the morning, and the snow lay already a foot deep over the wilderness world, he knew that he would have no chance to act upon the Cranston case until the snows melted in the spring. So he pushed all thought of it out of his mind and turned his attention to more pleasant subjects. It was true that he read the documents over twice as he lay in bed. Then he tied them into a neat packet and put them away where they would be quickly available. Then he thrust his head out of the window and let the great snowflakes sift down upon his face. It was winter at last, the season that he loved.

He didn't stir from the house, that first day of the storm. Snowbird and he found plenty of pleasant things to do and talk about before the roaring fire that he built in the grate. He was glad of the great pile of wood that lay outside the door. It meant life itself, in this season. Then Snowbird led him to the windows, and they watched the white drifts pile up over the low underbrush.

When finally the snowstorm ceased, five days later, the whole face of the wilderness was changed. The buckbrush was mostly covered, the fences were out of sight; the forest seemed a clear, clean sweep of white, broken only by an occasional tall thicket and by the great, snow-covered trees.

When the clouds blew away, and the air grew clear, the temperature began to fall. Dan had no way of knowing how low it went. Thermometers were not considered essential at the Lennox home. But when his eyelids congealed with the frost, and his mittens froze to the logs of firewood that he carried through the door, and the pine trees exploded and cracked in the darkness, he was correct in his belief that it was very, very cold.

But he loved the cold, and the silence and austerity that went with it. The wilderness claimed him as never before. The rugged breed that were his ancestors had struggled through such seasons as this and passed a love of them down through the years to him.

When the ice made a crust over the snow, he learned to walk on snowshoes. At first there were pained ankles and endless floundering in the drifts. But between the fall of fresh snow and the thaws that softened the crust, he slowly mastered the art. Snowbird—and Dan never realized the full significance of her name until he saw her flying with incredible grace over the snow—laughed at him at first and ran him races that would usually end in his falling head-first into a ten-foot snowbank. She taught him how to ski and more than once she would stop in the middle of an earnest bit of pedagogy to find that he wasn't listening at all. He would seem to be fairly devouring her with his eyes, delighting in the play of soft pinks and reds in her cheeks, and drinking, as a man drinks wine, the amazing change of light and shadow in her eyes.

She seemed to blossom under his gaze. Not one of those short winter days went by without the discovery of some new trait or little vanity to astonish or delight him,—sometimes an unlooked-for tenderness toward the weak, often a sweet, untainted philosophy of life, or perhaps just a lowering of her eyelids in which her eyes would show lustrous through the lashes, or some sweeping, exuberant gesture startlingly graceful.

Lennox wakened one morning with the realization that this was one of the hardest winters of his experience. More snow had fallen in the night and had banked halfway up his windows. The last of the shrubbery—except for the ends of a few tall bushes that would not hold the snow—was covered, and the roofs of some of the lower outbuildings had somewhat the impression of drowning things, striving desperately to keep their heads above water. He began to be very glad of the abundant stores of provisions that overcrowded his pantry—savory hams and bacons, dried venison, sacks of potatoes and evaporated vegetables, and, of course, canned goods past counting. With the high fire roaring in the grate, the season held no ills for them. But sometimes, when the bitter cold came down at twilight, and the moon looked like a thing of ice itself over the snow, he began to wonder how the wild creatures who wintered on the Divide were faring. Of course most of them were gone. Woof, long since, had grunted and mumbled his way into a winter lair. But the wolves remained, strange gray shadows on the snow, and possibly a few of the hardier smaller creatures.

More than once in those long winter nights their talk was chopped off short by the song of the pack on some distant ridge. Sometime, when the world is old, possibly a man will be born that can continue to talk and keep his mind on his words while the wolf pack sings. But he is certainly an unknown quantity to-day. The cry sets in vibration curious memory chords, and for a moment the listener sees in his mind's eye his ancient home in an ancient world,—Darkness and Fear and Eyes shining about the cave. It carries him back, and he knows the wilderness as it really is; and to have such knowledge dries up all inclination to talk, as a sponge dries water. Of course the picture isn't entirely plain. It is more a thing guessed at, a photograph in some dark part of an under-consciousness that has constantly grown more dim as the centuries have passed. Possibly sometime it will fade out altogether; and then a man may continue to discuss the weather while the Song from the ridge shudders in at the windows. But the world will be quite cold by then, and no longer particularly interesting. And possibly even the wolves themselves will then be tamed to play dead and speak pieces,—which means the wilderness itself will be tamed. For as long as the wild lasts, the pack will run through it in the winter. They were here in the beginning, and in spite of constant war and constant hatred on the part of men, they will be here in the end. The reason is just that they are the symbol of the wilderness itself, and the idea of it continuing to exist without them is stranger than that of a nation without a flag.
