Once a flock of wild geese, stragglers from the main army of waterfowl, passed overhead on their southern migration. They were many months too late. They called down their eerie cries,—that song that they had learned from the noise the wind makes, blowing over the bleak marshes. It wailed down to them a long time after the flock was hidden by the distant tree tops, and seemed to shiver, with curious echoes, among the pines. Trudging on, they listened to its last note. And possibly they understood the cry as never before. It was one of the untamed, primitive voices of the wilderness, and they could realize something of its sadness, its infinite yearning and complaint. They knew the wilderness now, just as the geese themselves did. They knew its cold, its hunger, its remorselessness, and beyond all, the fear that was bright eyes in the darkness. No man could have crossed that first twenty miles with them and remained a tenderfoot. The wild was sending home its lessons, one after another, until the spirit broke beneath them. It was showing its teeth. It was reminding them, very clearly, that in spite of houses built on the ridges and cattle pens and rifles and all the tools and aids of civilization, it was still unconquered.
Mostly the forest was heavily laden with silence. And silence, in this case, didn't seem to be merely an absence of sound. It seemed like a substance in itself, something that lay over the snow, in which all sound was immediately smothered and extinguished. They heard their own footfalls in the snow and the crunch of the sled. But the sound only went a little way. Once in a long time distant trees cracked in the frost; and they all stood still a moment, trying to fight down the vain hope that this might be some hunter from the valleys who would come to their aid. A few times they heard the snow sliding, with the dull sound of rolling window shade, down from the overburdened limbs. The trees were inert with their load of snow.
As the dawn came out, they all stood still and listened to the wolf pack, singing on the ridge somewhere behind them. It was a large pack. They couldn't make out individual voices,—neither the more shrill cry of the females, the yapping of the cubs, or the low, clear G-below-middle-C note of the males.
"If they should cross our tracks—" Lennox suggested.
"No use worrying about that now—not until we come to it," Dan told him.
The morning broke, the sun rose bright in a clear sky. But still they trudged on. In spite of the fact that the sled was heavy and broke through the snow crust as they tugged at it, they had made good time since their departure. But now every step was a pronounced effort. It was the dreadful beginning of fatigue that only food and warmth and rest could rectify.
"We'll rest now," Dan told them at ten o'clock. "The sun is warm enough so that we won't need much of a fire. And we'll try to get five hours' sleep."
"Too long, if we're going to make it out," Lennox objected.
"That leaves a work-day of nineteen hours," Dan persisted. "Not any too little. Five hours it will be."
He found where the snow had drifted against a great, dead log, leaving the white covering only a foot in depth on the lee side. He began to scrape the snow away, then hacked at the log with his ax until he had procured a piece of comparatively dry wood from its center. They all stood breathless while he lighted the little pile of kindling and heaped it with green wood,—the only wood procurable. But it didn't burn freely. It smoked fitfully, threatening to die out, and emitting very little heat.
