The sluggish dawn had barely cast its first glow across the measureless snows when Rainy roused him from heavy sleep. After a breakfast of boiled fat, meat, tea and hard bread, they gathered the four dogs together, and with much difficulty got them into traces. Mistisi, the leader, a bad dog when not working, strained impatiently in the moose-hide harness. Donald, when the packs had been strapped securely on, gave a quick final inspection, and then a word that sent the train moving toward the gate in the wall.

But few men were about, and an indifferent wave of the hand from these sped the party on its way. Outside the gate, Peter Rainy took the lead, breaking a path for the dogs with his snowshoes, while McTavish walked beside the loaded sled. Their course ran westward up the frozen Dickey River, which now lay adamant beneath the iron cold and drifting snow. Forty miles they would follow it, to the fork that led on the north to Beaver Lake, and on the south to Bolsover. Taking the south branch, they would then struggle across the wind-swept body of water, and follow the river ten miles farther, to a headland upon which stood the snow-muffled block-house of Fort Dickey.

If you draw a straight line north from Ashland, Wisconsin, and follow it for six hundred and fifty miles, you will find yourself in the vicinity of Fort Dickey, in the midst of the most appalling wilderness on the face of the globe. In that journey, you will have crossed Lake Superior and the great tangle of spruce that extends for two hundred miles north of it. North of Lake St. Joseph, which is the head of the great Albany River, whence the waters drain to Hudson Bay, you will strike north across the Keewatin barrens: Bald, fruitless rocks, piled as by an indifferent hand; great stretches of almost impenetrable forest, ravines, lakes, rivers, and rapids; all these will hinder and baffle your progress. Add to such conditions snow, ice, and eighty degrees of frost, and you have the situation that Donald McTavish faced the day he left Fort Severn.

[CHAPTER III]

A MYSTERIOUS MESSAGE

“What do you know about this murder?”

Donald sat at the dinner table in Fort Dickey with John Buller and Pierre Cardepie, his two assistants. A roaring log fire barely fought off the cold as they ate their caribou steak, beans, bread, and tea.

“Not much,” replied Buller. “The day after you left, one of the Indians tore in at midnight with the news. He said that he and his partner, the murdered man, had been met by Charley Seguis while running their trap-line, and that Charley had drawn the other aside in private conversation. Half an hour later, there had been sudden words, followed by blows, and, before Johnny could defend himself, Seguis had stabbed him. What they had been talking about the Indian didn't know, for Charley had hurried off immediately after the murder.”

“What direction did he take?” asked McTavish.

“The rumor declared that he went north, toward Beaver Lake.”
