A red fox ran into the empty church. In the middle of the floor he sat up and looked around. Nothing stirred--not the painted figures on the wooden walls, nor the boy who now stood in the doorway. This boy was gray-eyed and flaxen-haired, and might have been eleven or twelve years old. He was looking for the good old priest, Father Ansgar, and the wild shy animal eyeing him from the foot of the altar made it only too clear that the church, like the village, was deserted. Father Ansgar was dead of the strange swift pestilence that was called in 1348 the Black Death. So also were the sexton, the cooper, the shoemaker, and almost all the people of the valley. A ship had come into Bergen with the plague on board, and it spread through Norway like a grass-fire. Only last week Thorolf Erlandsson[1] had had a father and mother, a grandmother, two younger sisters and a brother. Now he was alone. In the night the dairy woman and the plowmen at Ormgard farm had run away. Other farms and houses were already closed and silent, or plundered and burned. Ormgard being remote had at first escaped the sickness. Thorolf turned away from the church door and began to climb the mountain. At the lane leading to his home he did not stop, but kept on into the woods. It was not so lonely there. Up and up he climbed, the thrilling scent of fir-balsam in his nostrils, the small friendly noises of the forest all about him. Only a few months ago he had come down this very road with his father, driving the cattle and goats home from the summer pasture. All the other farmers were doing the same, and the clear notes of the lure, the long curving horn, used for calling the cattle and signaling across valleys, soared from slope to slope. There was laughter and shouting and joking all the way down. Now the only persons abroad seemed to be thieving ruffians whose greed for plunder was more than their fear of the plague. A thought came to the boy. How could he leave his father's cattle unfed and uncared for? What if he were to drive the cows himself to the saeter and tend them through the summer? He faced about, resolutely, and began to descend the hill. Within sight of the familiar roofs he heard some one coming from the village, on horseback. It proved to be Nils the son of Magnus the son of Nils who was called the Bear-Slayer, with a sack of grain and a pair of saddlebags on a sedate brown pony. Nils was lame of one foot and no taller than a boy of nine, although he was thirteen this month and his head was nearly as large as a man's. He had been an orphan from baby-hood, and for the last three years had lived in the priest's house learning to be a clerk. "Hoh!" called Nils, "where are you going?" "To the farm to get our cattle and take them to the saeter. There is no one left to do it but me." "Cattle?" queried the other interestedly, "She will be glad of that." "She!" said Thorolf, "who?"
