He vanished through an inner door and Frank soon heard him throwing things about. The suspense of the next few moments was almost unbearable. A pulsating radiance alternately lighted up the room and grew dim again, and the roar and crackle of the fire set his nerves tingling. Then Harry ran back toward him. "I can't find any giant powder," he reported, and added, "get hold of the keg. We'll carry it between us." Frank set his lips as they sprang out of the door with it. The keg was not remarkably heavy, but it was an awkward shape and too big for either of them to carry on his shoulder or beneath his arm. Indeed, Frank felt his hands slipping from its rounded end and he was horribly afraid of dropping it among the patches of smoldering undergrowth and glowing fragments which lay all about him. A few moments later thick smoke whirled about him, and he hardly breathed as he struggled through it until it blew away again. Then, to his relief, he saw that the house was some distance behind them and they were clear of the worst of the sparks. They went on, however, to the opposite side of the clearing, where they deposited the powder, and then dropped the detonators a little farther on, after which Harry sat down on the frozen ground panting heavily. "It's done and I want to get my breath," he said. "The next time I burn a slashing I'll see there's no powder about the place before I begin." Frank made no answer. He was glad to sit still and recover, for the strain had told on him. Indeed, he was almost sorry when his companion stood up again. "Perhaps we had better get back and pitch some water on the roof," he suggested. "I was too busy to think of that before." The wind seemed to be dropping and the sparks were not quite so bad when they reached the house. They found a bucket, and after smashing more of the ice upon the shallow well Frank climbed up on the woodshed which reached to the low roof. The latter was covered with cedar shingles and he wondered why it had not ignited, because the sparks were still dropping upon it and there were several charred spots. This, however, was not a question of much consequence, and Harry kept him busy during the next half hour sluicing the roof with water which he passed up in the bucket. Some of it went over Frank's hands and clothing and it was icy cold, but they worked on steadily while the fire worked back farther from them into the bush. It had burned most fiercely when it had the dry branches in the slashing to supply it, but these were all licked up, and though the small stuff blazed the great standing trunks would not burn. There were already rows of them rising, charred and blackened columns, behind the slashing. At last Harry called Frank down from the roof. "You can let up," he said. "It's hardly likely we'll have any more trouble. There's a lamp and some canned stuff in the shack, and as we'll have to camp here I'll make some coffee. It's quite dark now."
