This, however, did not take Thirlwell far and he resumed his walk, wondering what Driscoll had been doing and why he feared to be disturbed. It was plain that he had taken some trouble to put Thirlwell off the track and might have succeeded had not the hoarseness of his voice given the latter a hint. Thirlwell felt puzzled, but could find no clue, and deciding that the matter was not important presently dismissed it. For all that, he resolved to watch Driscoll, but saw nothing to excite his suspicions for the next week or two. Then the man bought all the provisions Scott would let him have and loading his canoe started for the North. CHAPTER V A NIGHT'S WATCH Winter began unusually soon and a blizzard raged about the shack one evening when Scott and Thirlwell sat near the stove. The small room smelt of hot-iron and the front of the stove glowed a dull red, but the men shivered as the bitter draughts swept in. Thirlwell watched the skin curtain he had nailed across the window bulge while the snow beat savagely against the glass, and then picked up a book. Presently Scott hung a bearskin on the back of his chair. "It's a pretty good hide although the forequarter's cut away," he said. "Still I don't know that I wanted the thing and reckon the half-breed who sold it me got its value in cartridges and food. Now transport's difficult, I hope he and his Indian friends won't bring us any more of the damaged stock they can't sell to the Hudson's Bay." Thirlwell nodded. The rivers were frozen and canoeing was stopped, while the bush was deep in fresh, loose snow. It would be a long and strenuous business to break a trail to the south, and in winter the mine was often cut off from the settlements. Provisions sometimes ran short, but Scott found it hard to refuse the starving Indians a share of his supplies. "You bought a fine skin," he resumed. "I haven't seen the thing since. What have you done with it?" "I sent it away," said Thirlwell. "Old Musquash said he'd try to make the settlements and took it out for me." "He'll probably get through, though I don't think a white man could. But I didn't know you had friends in Canada." Thirlwell did not reply. He had bought the skin for Agatha and now wondered what she would think about his present, or whether she might feel he ought not to have sent it. Still he doubted if the skin would arrive, because the old half-breed would meet with many dangers on the way. Thirlwell pictured him hauling his sledge up thinly frozen rivers, crossing wide lakes swept by icy gales, and plunging into tangled forests smothered in snow. The thought of it emphasized the sense of isolation one often felt at the mine, but while he mused there was a knock at the door. "I expect it's an Indian come to beg for food," Scott remarked and the door swung open.
