eaten whatever refreshment he had while riding on his sled or while on foot, for no traces of a fire or a resting place could the boys’ eyes discover.
One clew alone the thief had left behind him, and that was in the form of numerous stubs of cigarettes which had been rolled by hand out of coarse yellow paper. But outside of this sign there was nothing but the sled marks to guide them. One thing about the trail that has not yet been mentioned is that the man was back-trailing. That is to say that, on leaving the boys’ camp, he had followed the same path by which he had come, and in places the two tracks could be seen where the sled had swung out a little.
After a time they found that a snow storm, which must have fallen in the vicinity during the night, had entirely wiped out the “coming” track, leaving only the fresh marks of the “going” trail.
From this fact the boys deduced that the man might have turned off somewhere on his journey to their camp, but they cared little for this. It was his fresh trail that they were following hot upon, like hounds upon the scent.
All the way, too, went the trail of the wolverine, and, judging from the tracks, the boys guessed that the animal had been traveling fast. This looked ominous, for the wolverine is not, as a rule, an energetic animal, and proved at least to Tom’s mind that the robber must be traveling very quickly.
He pointed this out to Jack, who agreed with him. But neither of the boys said a word about turning back. They were far too nervy for that, and, having started out, such an idea as quitting did not once enter their heads. All that afternoon they kept grimly on.
At about three o’clock, or shortly thereafter, the sun grew dim and low. Half an hour later only a pale twilight lingered about them, for at that time of year in the northern wilds the evening sets in early.
Above their heads, from the darkening canopy of the sky, the stars, a million pin points of light, began to shine. The snow turned a dull, steely blue as the light shut in. A slight breeze stirred in the hemlocks and spruces. It began to grow noticeably colder, too.
But as the daylight died another light, a wonderful mystic glory of radiance, began to glow in the northern sky. Against its wavering, shimmering, unearthly splendor every twig on every tree stood out as though carved in blackest ebony. The brush was shrouded in deepest sable, and the shadows lay upon the snow as black as a crow’s wing.
Everywhere was a deep, breathless hush, except where the light wind caused a huddled mass of snow on an interlaced branch to slip ground-ward. The great solitudes appeared to be composing themselves for sleep. On the hard, frozen surface the boys’ snowshoes creaked almost metallically as they pressed on, following in the dimming light the two parallel lines that had begun to burn themselves into their brains.
They knew when they set out that it was going to prove a stern chase; now they saw that unquestionably it was likewise to be a long one. How long they could not guess. They passed a small stream. In the silence they could hear the ice “crack-cracking!” with that startling sound that is one of the most mystic of the voices of the woods. It grew bitterly cold. Tom began to look anxiously about him. They must find a lodging for the night. The question of sleeping in the open did not bother him. Timber was plenty, and they could make an evergreen shelter and soon have a roaring fire to warm their blood. He was merely prospecting for a place that looked a likely one.
And then, suddenly, something happened that sent an involuntary chill running up and down the spines of both boys.
From the westward, through the long, melancholy aisles of straight-trunked trees, the sound had come. Out of the silence it was borne with a chilling forboding to them. It was a long-flung, indescribably forlorn sound, and seemed to fill the silences, coming from no definite spot after an instant’s listening.
It deepened and swelled, died away and rose like the sound of distant church bells. Then, while they stood listening, involuntarily brought to a swift, startled halt, it died out uncannily, sinkingly, and the silence shut down again.
“It’s the wolves!” said Tom in a low, rather awestruck voice.
The boy was right. The gray rangers of the big timbers were abroad seeking their meat from God.
CHAPTER VII – IN THE TRAPPER’S HUT
Now, to a reader who has never been a woodsman, who has never penetrated the silences that lie north of Fifty-three, the word “wolves” conveys a distinct impression of uneasiness.
The cold fact is that the northern woodsman stands rather in contempt of wolves. He has no use for them, but he does not fear them; and the wolves for their part – except in some startling exceptions – leave mankind alone.
The boys had been long enough in the Northland to share this feeling, and it was not fear that brought them to a halt at the long, melancholy ululation that told them of the “gray brothers” wishing each other “good hunting.” It was quite another feeling: the sense of their isolation, that the moaning cry had brought sharply home to them, the loneliness of the solitudes about them, the possibly dangerous nature of their quest.
“Wow! but that sound always makes me shiver,” said Jack, glancing about him, as if he expected to see a gray head pop out from behind the trees at any moment.
“Yes, it never sounded very good to me, even when we were lying snugly in our bunks on the good old Yukon Rover,” agreed Tom. “I wish we could find some trapper’s shack or hut hereabouts. I wouldn’t mind making a good camp with some company around, for to-night anyhow.”
“Why, you talk as if we might be a long time in the woods,” said Jack, in rather dismayed tones.
“And so we may be, for it is up to us now to keep on that trail till we find the man that made it, or else run it out.”
Jack did not make any reply to this. His spirits had been good all day, and he had looked upon the chase rather in the light of an enjoyable adventure than anything else.
But now the twilight desolation, the fading line of light in the west and the long howl of hunting wolves, which ever and anon swelled and died out in the distance as they stood there, combined to give him a sense of forboding and creepiness.
Tom’s cheery voice aroused him.
“We can push on a way yet, anyhow,” his elder brother was saying; “even half a mile farther will be better than nothing, and who knows that we may not come on some Indian camp or trapper’s shack, where we can get a hot supper and find, maybe, some news of our visitor.”
Jack, thus admonished, roused himself. By an effort he put aside his gloomy thoughts. Side by side through the trees the two young adventurers forged ahead. But Jack soon began to sag behind. It was plain that he was beginning to get fagged. It was small wonder. They had come thirty-five miles that day, as Tom’s speedometer showed, which is a fair journey for a grown man, let alone boys. A seasoned woodsman can make fifty miles a day on snowshoes and pull up with no feeling but a huge appetite. But, although the boys were well muscled and used to following the trail, they could not hope to compete with the lifelong rangers of the forest in endurance.
Tom was just thinking of making camp right where they then were, in a grove of hemlocks and stunted spruces, when he gave a sudden cry of joy.
“Hurray! Jack, old boy! Talk about luck!”
“What’s up?”
“Don’t you know yet?”
“I do not.”
“Then you are a worse woodsman than I thought you.”
“You might explain. Have you gone crazy?”
“Not just yet. Don’t you smell anything?”
“Um – a-h-h-h! Yes, I do. Smoke.”
“Wood smoke, Jack, and wood smoke means a fire, and fire means a human being.”
“Yes, and a human being may – mean – may mean – ”
“Well?”
“A human being that may make us a lot of trouble; for instance, the man who stole that skin!”
“Cracky!
