They continued on down the fire line, pausing every once in a while to rake and scrape leisurely at the heavy bark beneath some blazing stub. The fierce, hard work was over. All along the fire line from the dome of granite over the ridge down to Granite Creek the fire had consumed all the light fuel on its own side the defence. No further danger was to be apprehended in the breaking across. But everywhere through the now darkening forest blazed the standing trees. A wind would fill the air with brands; and even in the present dead calm those near the line were a threat. The men traversed the fire line from end to end a half-dozen times. Bob became acquainted individually and minutely with each of the danger spots. The new temporary features of country took on, from the effects of vigilance and toil, the dignity of age and establishment. Anxiously he widened the path here, kicked back glowing brands there, tried to assure himself that in no possible manner could the seed of a new conflagration find germination. After a long time he heard three shots from up the mountain. This, he remarked, was a signal agreed upon. He shouldered his blackened implements and commenced a laborious ascent. Suddenly he discovered that he was very tired, and that his legs were weak and wobbly. Stubs and sticks protruded everywhere; stones rolled from under his feet. Once on a steep shale, he fell and rolled ten feet out of sheer weariness. In addition he was again very thirsty, and his canteen empty. A chill gray of dawn was abroad; the smell of stale burning hung in the air. By the time he had staggered into camp the daylight had come. He glanced about him wearily. Across a tiny ravine the horses dozed, tied each to a short picket rope. Bob was already enough of a mountaineer to notice that the feed was very scant. The camp itself had been made under a dozen big yellow pines. A bright little fire flickered. About it stood utensils from which the men were rather dispiritedly helping themselves. Bob saw that the long pine needles had been scraped together to make soft beds, over which the blankets had been spread. Amy herself, her cheeks red, her eyes bright, was passing around tin cups of strong coffee, and tin plates of food. Her horse, saddled and bridled, stood nearby. "Take a little of this," she urged Bob, "and then turn in." Bob muttered his thanks. After swallowing the coffee, however, he felt his energies reviving somewhat. "How did you leave things at the lower end?" Morton was asking him. "All out but two or three smouldering old stubs," replied Bob. "Everything's safe." "Nothing's safe," contradicted Morton. "By rights we ought to watch every minute. But we got to get some rest in a long fight. It's the cool of the morning and the fire burns low. Turn in and get all the sleep you can. May need you later." "I'm all in," acknowledged Bob, throwing back his blanket; "I'm willing to say so." "No more fire in mine," agreed young Elliott.
