CHAPTER XVIII—TOM PLAYS DETECTIVE.

While the others were getting things in readiness for resuming the march the next day Tom began an investigation. He had at first thought that the mysterious noises of the night had been caused by their old enemy, but some reflection made him believe that he was mistaken.

In the first place the thief, having had the good fortune to have his trail wiped out by the snow, was not likely to be foolish enough to come back and leave a fresh one. In the second, he was probably aware that his first attempt had failed to scare the boys off his track. At any rate, his continued haste along the trail appeared to conduce to such a belief.

Tom had noticed that the white object which swooped down on old Joe, scaring him almost into a fit, was a big white owl, in all probability bewildered and blinded by the fire glow. He had observed, also, that the mysterious noises appeared to come from the old hut, and the strange “booming” sounds, as nearly as he could make out, had also emanated from the same quarter.

The hut, then, appeared to be the logical place in which to look for the origin of the series of happenings that had so alarmed the venerable and superstitious Joe Picquet.

The first thing that Tom noticed when he entered the hut was something white lying on the hearthstone of the chimney. On closer inspection this proved to be the body of an Arctic hare. It was badly mangled and torn, as if something had been eating it. Tom stooped and peered up the chimney.

“Who-oo-oo-oo!” he shouted, at the same time beating the sides of the smoke shaft with a stick that he had selected from a pile of firewood laid in by the former occupant of the ruined hut.

His voice rang up the chimney like the noise of a train in a tunnel. At the same instant there came a thunderous booming sound and the rush and roar of wings. Tom had just time to dodge back before there came flopping and scratching and squeaking down the chimney the body of a huge white owl.

Tom fell upon it, but before he could secure the bird it had dug into his arm with beak and talons, and then, with a weird shriek, blundered across the hut and out through an unglazed window into the open air.

“Gone!” exclaimed Tom as he saw this. “And,” regretfully, “it would have made a bully trophy stuffed, too. However, the mystery of the Flying Wolves is explained. That booming sound was made by the flapping of the owl’s wings in the wide chimney as it flew down there with that white hare it had caught. I’ve heard that chimney swallows make the same booming in chimneys at home as they enter and leave their nests.

“As for the screams and shrieks, the cries of that poor hare explains that easily enough. Naturally, they sounded louder and as if they were up in the air, proceeding as they did from the top of the chimney. The rest of the mystery must be laid to old Joe’s imagination, which appears to be in first-class working order.”

Tom couldn’t help giving mischievous glances at Joe as, over their breakfast, he told the others the result of his investigations. But the old man’s face was scornful as Tom proceeded. When the boy had concluded, Joe, who had patiently heard him out, had his say. It was brief and to the point.

“You only theenk. Joe Picquet know. Many men know ’bout Loups Galoups—c’est sufficient.”

Tom saw that the old man was not in the least convinced that the noises were not of supernatural origin. So hard is it to shake superstitious beliefs, especially in the case of a man like old Joe, who had been born and brought up in the wilds, and who rarely came into contact with cities or life as it was beyond the wilderness.

They came to Otter Lake a few hours after their early start. On the banks of the lake they found a party consisting of two families of Indians. They were having a sort of carouse. The bucks had had the good fortune to kill three deer the day before. As is the custom with the Indians, the occasion was being observed by a celebration.

The Indians would not move on again till all the meat had been eaten or wasted. They greeted the newcomers with unusual cordiality, and the squaws threw big lumps of raw meat to the dogs, which the mamelukes gulped down in great swallows and then yapped and barked for more.

They insisted on the party halting to eat with them and partake of the unaccustomed plenty of the camp. This Joe was the more willing to do as he guessed that from the Indians he might get some news of the fugitive. But in their present mood the Indians were giving all their time to jollity of a decidedly rough character, and Joe knew better than to offend them by talking business until the time was ripe.

While they waited to eat, the squaws bustled about collecting wood. The boys hated to see women thus employed, but they knew that they dare not offer to do it; so they sat silent while old Joe and the Indians smoked and talked. The Indians were telling of the great hunt of the three deer, enlarging, as is their custom, every little detail till the story stretched out to endless lengths.

Then they discussed dogs, a topic of endless interest in the North, where dogs are infinitely more valuable than horses, and where oftentimes a life, or many lives, may depend on their gameness and reliability. This topic exhausted, they turned to the weather.

In a land where so much depends upon its moods, the weather is a subject of vital interest. The Indians told of the big snows they had seen, and old Joe Picquet related his similar experiences, and so the chat ran along till the squaws announced that everything was ready for them to eat.

They sat about the fire in the drafty tepee, eating off bits of birch bark. That is, the white men did. The Indians used their fingers. At last the meal was finished, pipes lighted, and old Joe felt at liberty to ask the questions he was dying to put.

At first the Indians shook their heads. They had seen no white man. But then one of the squaws interjected a remark. Wild Bird, another of the squaws, had seen that very morning, while gathering wood to the north, the trail of a sled. She had examined it and had found by it an odd object. She had brought that object into camp. Would she produce it? She would.

From a corner of the tepee the squaw shyly produced her find. The boys could have uttered a cry of joy as they saw what it was.

The fag end of a yellow cigarette! Assuredly, then, the trail Wild Bird had seen was that of the fugitive. It began about two miles to the north by a tall “Rampick” (dead tree), near which he had camped, judging by the remains of a fire, and from which he had hacked off some dead limbs. And then Wild Bird herself gave another bit of evidence to clinch the identification. She had remarked the man’s funny snowshoes. Never had she seen any like them.

“Boosh! Mes garçons! We have found zee trail once more! Bien!”

Old Joe’s face beamed. But although they were anxious to hurry on, they could not leave the friendly Indians hastily without a severe breach of etiquette. But at length the social code of the tribe was satisfied, and, with well-fed dogs in the traces, they got under way once more. Wild Bird and another Indian went with them part of the way, so as to be sure that they would not miss the spot at which they were to pick up the trail.

At last they reached the gaunt “Rampick,” good-byes were said, and they had the satisfaction once more of following the two familiar parallel lines in the snow and beside them the tracks of the odd-shaped snowshoes. The sky was gloomy and gray, but the Indians had said there would be no more snow.

They journeyed on through a melancholy land all that afternoon. That fall there had been a forest fire, and the blackened stumps of the trees that had not fallen stood out, etched in ebony black, against the dreary gray sky.

It was a pensive and melancholy land. But through it all, to brighten the trail like a streak of vivid scarlet, was the track of the sled, the sled on which reposed the stolen black fox skin. And beside it, as if to assure them they were on the right track, lay at intervals little yellow-wrapped rolls of tobacco.

“Zee time ees not long now,” declared old Joe, when they camped that night on the edge of a gloomy little lake tucked away between two rocky ridges.
