First, after this barricading, came the fire and collection of a fine heap of dead wood for the night. Then supper--fried bacon, bread, and tea; then the changing of foot-gear, and finally the two crawled into their fur-lined bags, feet foremost, and drew them up over their heads. That is the only way to keep warm, because otherwise the cold air is bound to creep in somewhere. If you cover your head as well, you may feel a bit stuffy, but you are not cold.

Robin, who had no bushy tail to curl round over his nose and toes as the husky dogs do, came and made his bed between their two bags. And then there was silence in the strange, lonely camp, miles away from a human habitation. The boughs overhead and the over-reaching rock protected them from falling snow, but every now and then a flake sizzled on to the fire. The light of the burning wood cast a pink glow on the snow wall of their barrier, and with all the loneliness and cold there was a sense of comfort and even security.

Nell had arranged the pile of fresh wood close to her head so as to be within reach for replenishing the fire. For a time she could not sleep--in spite of the terribly long day just passed and the sleepless night of work before that. She could not throw off the feeling of responsibility, or that liveliness of mind that made her obliged to keep on following the doings of Jan Stenson in her imagination. Had they escaped him or would he follow?

Twice she rose on her elbow and reached out of her bag to throw handfuls of wood on the fire, both times Robin raised his head to watch her doings, and she saw the shine of the flame light on his deep-set eyes. David was sound asleep, jerking a little and making grunts and distressful noises, as his hardworked muscles reminded him of the day's labour.

Then the girl fell asleep, too, deeply asleep; and the camp was quite still but for the faint crackle of wood as the fire died down.

It was about midnight when Nell was roused by a low growling from the hound. It must have gone on for some time before the girl realised it, because she was aware of it in her dreams after a fashion. But she was so deeply asleep that waking herself was like coming up out of a well, by slow stages.

Then she put her nose cautiously out of her furry nest and gazed round. It was dark, except for the faint paleness of the snow, for of course the rock barricade made a blackness, and the trees were fairly thick above. Of the fire remained only a scatter of red sparks and white ashes.

Nell raised herself to a sitting posture, bag and all, and stayed absolutely quiet, looking about to realise what the trouble was, if any. She did not attempt to put wood on the fire even. She hardly breathed.

From somewhere close, but not on the ground, came a very slight crack, the crack of dead wood. This was nothing, because the weight of snow would break a twig any time, apart from the movings of grey squirrels, chipmunks or other furry things that made shelters in the hollows of trunks. She was not afraid. Indeed, she firmly believed that there was only one event that could shake her peace of mind seriously, and that was the knowledge that the trapper was really on their trail.

She was just going to lie down again when something made her look up at the top of the rock that shielded them on the side they had made their beds. It might have been ten or twelve feet--hardly more--and perpendicular, but a broken surface mostly grown over with the coarse grey tinted moss that deer eat in winter.
