Speechless from a horrible, sickening realization of all which that terrible shock might mean to those whom they were striving to save, Ned silently helped her forward. They had gone but a few steps, when there suddenly burst upon the dark and stormy heavens a dull, red glare, which grew brighter moment by moment, and on emerging from the timber into the open ground, a frightful scene met their gaze. Dense clouds of smoke were pouring from the shafts of the nearest mine, while, at a little distance, could be seen the mills, their whole interior already ablaze with light. In that end of the buildings containing the sorting rooms and Haight's office, the fire was raging, having come in contact with quantities of chemicals which had increased its fury. "Great Cæsar!" ejaculated Ned, "the mills were struck, and are on fire." But Leslie uttered a sharp cry, and ran swiftly down the path to where Lyle lay unconscious, followed quickly by Ned. "Poor child, poor child!" she moaned, "oh, merciful heaven, she came too late, and they are all lost!" Then, as she knelt beside the unconscious form, there came another terrific explosion, which seemed to jar even the rocks about them to their very foundations, while from the already smoking shafts, the flames now issued, towering higher and higher, and adding new terror to the scene. Men were seen running from all directions, from the distant groups of mines, rushing to the burning mills, where the little fire corps belonging to the camp, were already engaged in a futile battle with the flames; but around the Yankee Boy mine there was no sign of life. The rain now began to descend in torrents, and the first dash of the storm seemed to revive Lyle, whom Leslie and Ned had raised to a sitting posture in their efforts to restore her to consciousness. Slowly she opened her eyes with a bewildered look, then springing to her feet, still weak and trembling, but resolute and determined, she gazed about her at the flaming shafts and burning mills, and suddenly cried, "Oh, I can remember now! I remember it all, it has come back to me,--the terrible wreck, the burning cars all around us, and my mother crushed in the wreck; then the people carried us out and they put me down beside her, lying so white and still, and then,--then that villain came and took me away,--I can see it all," and she shuddered. Then looking at Leslie and Ned, who were watching her with startled faces, she seemed trying to recall the present situation. Before either of them could speak, however, there came the report of another explosion, more distant and deeper underground than any that had yet occurred, and the sound seemed to bring back to Lyle the memory of her last moments of consciousness before the first terrible shock, while the faces of her companions were blanched with terror.
