Before going to work on the hiding part of the business, the girl put back the log, knocked it firmly into place and put the bearskin over it. Then she gathered up the two bags, and stood holding them thoughtfully as her fingers ran over the bulk and shape of the paper.

At that moment her attention was drawn to Robin by his action. He moved slowly over to the door, and with drooping head blew sniffing breath along the lower part of it. He made no sound, but the hackles on his neck rose stiffly, and the snow squeezing in under the door was blown out by his breath.

Then, from the forest came the far-off howl of a husky dog--or a wolf.

Nell knew that the huskies in an Indian camp will howl in the night for hours. All of them together, too. The most mournful and tragic sound, though they are not unhappy. In the very coldest weather they will bury themselves in the snow--especially when they are on the Long Trail--bury themselves entirely and so sleep warm. But in the camps they will wander round about and in and out, fighting with each other and howling in chorus as their ancestors the wolves must have done in far-away days when all this great snow country was wild as the Barren Lands up in the north near the Circle.

Nell listened, startled. Why should a husky dog be away out there by itself? It was so unlikely that she settled this must be a lone wolf. But why did it howl? They seldom did that unless they were in full cry, a pack of them on the track of a deer. Also wolves were not very plentiful about this part; though, of course, they might come when driven by hunger--ravenous, and savage.

"Well, it doesn't matter," thought the girl, and she spoke to Robin gently. "Only a wolf, old man. He won't interfere with us."

Even as she stopped speaking, the wolf howled again. This time it was nearer. Robin scratched at the foot of the door and snuffed again heavily, but he did not growl. That was reassuring, because Nell knew he would have growled had it been an enemy--but why didn't he growl at a wolf? That seemed odd. Wolf or husky would have been equally objectionable to Robin.

These thoughts flashed through the girl's mind, the while she pushed the leather bags under the package of pelts, looked to the priming of her little weapon, and pulled the hood of her parka up to cover her head and face. Not only for protection from cold did she do this, but for disguise also in a way, because, as she was dressed like a man in leather breeches with the fur inwards and leather moccasins--or leggings with boots to them--being so tall and strong she would at once be mistaken for a man when the parka tails fell round her face.

All this took but a couple of minutes; Nell always moved quickly. Then she grasped the bolt, pushing Robin aside with her foot and talking to him in a low voice.

"We must have a look, eh, boy?" she said. And at that instant the dreary howl came from the back of the log house, close where the wood was thickest and the hill rose steeply.
