"The red flag is over Langlois' cabin!" he cried. "I fired my rifle and shouted. There is no life! Langlois is dead!"

"Great God!" groaned Williams.

His red face changed to a sickly pallor, and he stood with his thick hands clenched, while Cummins took charge of the dogs and Jan went into the store for something to eat.

Mukee and Per-ee returned to the post the next day. Young Williams followed close after them, filled with terror. He had found the plague among the Crees of the Waterfound.

Each day added to the gloom at Lac Bain. For a time Jan could not fully understand, and he still played his violin and romped joyfully with Mélisse in the little cabin. He had not lived through the plague of nineteen years before. Most of the others had, even to Mukee, the youngest of them all.

Jan did not know that it was this Red Terror that came like a Nemesis of the gods to cut down the people of the great Northland, until they were fewer in number than those of the Sahara desert. But he learned quickly. In February, the Crees along Wollaston Lake were practically wiped out. Red flags marked the trail of the Nelson. Death leaped from cabin to cabin in the wilderness to the west. By the middle of the month, Lac Bain was hemmed in by the plague on all sides but the north.

The post's trap-lines had been shortened; now they were abandoned entirely, and the great fight began. Williams assembled his men, and told them how that same battle had been fought nearly two decades before. For sixty miles about the post every cabin and wigwam that floated a red flag must be visited—and burned if the occupants were dead. In learning whether life or death existed in these places lay the peril for those who undertook the task. It was a dangerous mission. It meant facing a death from which those who listened to the old factor shrank with dread; yet, when the call came, they responded to a man.

Cummins and Jan ate their last supper together, with Mélisse sitting between them and wondering at their silence. When it was over, the two went outside.

"Mukee wasn't at the store," said Cummins in a thick, strained voice, halting Jan in the gloom behind the cabin. "Williams thought he was off to the south with his dogs. But he isn't. I saw him drag himself into his shack, like a sick dog, an hour before dusk. There'll be a red flag over Lac Bain in the morning."

Jan stifled the sharp cry on his lips.
