The traveller met with no adventures until the third day, when he saw several boys playing outside the entrance to their dwelling, which appeared to be merely a cave in the side of a hill.
"Here comes our brother-in-law!" they cried, and all ran back into the cave.
The young man was curious to know what this meant, and he went boldly in. Opposite the door of the cave there sat a handsome young woman, while her father and mother were seated upon either side of the fire. The old man at once arose and greeted the stranger.
"Ho, my son-in-law!" he exclaimed; whereupon the old wife served him with food and waited upon him hospitably.
It appeared, however, that the young woman was kindly disposed toward this good-looking youth, for she soon contrived to warn him secretly of her father's intentions toward him.
"When my father takes you hunting with him," she said, "you must take care always to keep behind him. If he tells you to follow any animal, do not do so, but shoot it from where you stand!"
Next day the old man invited his guest to hunt, and by and by they saw a white Marten in the wood.
"Chase it, chase it, son-in-law!" exclaimed the old man, but the youth stood still and killed the creature with an arrow from his quiver. Alas, it was no marten, but one of the boys whom he had seen playing outside the cave!
