"Listen again," said Dale.
Bo was asleep. And Helen, listening, at once caught low, distant roar.
"Wind. It's goin' to storm," explained Dale. "You'll hear somethin' worth while. But don't be scared. Reckon we'll be safe. Pines blow down often. But this fellow will stand any fall wind that ever was.... Better slip under the blankets so I can pull the tarp up."
Helen slid down, just as she was, fully dressed except for boots, which she and Bo had removed; and she laid her head close to Bo's. Dale pulled the tarpaulin up and folded it back just below their heads.
"When it rains you'll wake, an' then just pull the tarp up over you," he said.
"Will it rain?" Helen asked. But she was thinking that this moment was the strangest that had ever happened to her. By the light of the camp-fire she saw Dale's face, just as usual, still, darkly serene, expressing no thought. He was kind, but he was not thinking of these sisters as girls, alone with him in a pitch-black forest, helpless and defenseless. He did not seem to be thinking at all. But Helen had never before in her life been so keenly susceptible to experience.
"I'll be close by an' keep the fire goin' all night," he said.
She heard him stride off into the darkness. Presently there came a dragging, bumping sound, then a crash of a log dropped upon the fire. A cloud of sparks shot up, and many pattered down to hiss upon the damp ground. Smoke again curled upward along the great, seamed tree-trunk, and flames sputtered and crackled.
Helen listened again for the roar of wind. It seemed to come on a breath of air that fanned her cheek and softly blew Bo's curls, and it was stronger. But it died out presently, only to come again, and still stronger. Helen realized then that the sound was that of an approaching storm. Her heavy eyelids almost refused to stay open, and she knew if she let them close she would instantly drop to sleep. And she wanted to hear the storm-wind in the pines.
A few drops of cold rain fell upon her face, thrilling her with the proof that no roof stood between her and the elements. Then a breeze bore the smell of burnt wood into her face, and somehow her quick mind flew to girlhood days when she burned brush and leaves with her little brothers. The memory faded. The roar that had seemed distant was now back in the forest, coming swiftly, increasing in volume. Like a stream in flood it bore down. Helen grew amazed, startled. How rushing, oncoming, and heavy this storm-wind! She likened its approach to the tread of an army. Then the roar filled the forest, yet it was back there behind her. Not a pine-needle quivered in the light of the camp-fire. But the air seemed to be oppressed with a terrible charge. The roar augmented till it was no longer a roar, but an on-sweeping crash, like an ocean torrent engulfing the earth. Bo awoke to cling to Helen with fright. The deafening storm-blast was upon them. Helen felt the saddle-pillow move under her head. The giant pine had trembled to its very roots. That mighty fury of wind was all aloft, in the tree-tops. And for a long moment it bowed the forest under its tremendous power. Then the deafening crash passed to roar, and that swept on and on, lessening in volume, deepening in low detonation, at last to die in the distance.
