She could hear the beating of her own heart through his words; she longed to look at the eyes and lips that told her this, and read the meaning his voice alone could not entirely convey. For the first time she felt the loss of her sight. She did not know that it was, in this moment of happiness, the last blessing vouchsafed to her miserable life. A few moments of silence followed, broken only by the distant rumor of the conflagration and the crash of falling boughs. "It may be an hour yet," he whispered, "before the fire has swept a path for us to the road below. We are safe here, unless some sudden current should draw the fire down upon us. You are not frightened?" She pressed his hand; she was thinking of the pale face of Dunn, lying in the secure retreat she had purchased for him at such a sacrifice. Yet the possibility of danger to him now for a moment marred her present happiness and security. "You think the fire will not go north of where you found me?" she asked softly. "I think not," he said; "but I will reconnoitre. Stay where you are." They pressed hands and parted. He leaped upon the slanting trunk and ascended it rapidly. She waited in mute expectation. There was a sudden movement of the root on which she sat, a deafening crash, and she was thrown forward on her face. The vast bulk of the leaning tree, dislodged from its aerial support by the gradual sapping of the spring at its roots, or by the crumbling of the bark from the heat, had slipped, made a half revolution, and, falling, overbore the lesser trees in its path, and tore, in its resistless momentum, a broad opening to the underbrush. With a cry to Low, Teresa staggered to her feet. There was an interval of hideous silence, but no reply. She called again. There was a sudden deepening roar, the blast of a fiery furnace swept through the opening, a thousand luminous points around her burst into fire, and in an instant she was lost in a whirlwind of smoke and flame! From the onset of its fury to its culmination twenty minutes did not elapse; but in that interval a radius of two hundred yards around the hidden spring was swept of life and light and motion. For the rest of that day and part of the night a pall of smoke hung above the scene of desolation. It lifted only towards the morning, when the moon, riding high, picked out in black and silver the shrunken and silent columns of those roofless vaults, shorn of base and capital. It flickered on the still, overflowing pool of the hidden spring, and shone upon the white face of Low, who, with a rootlet of the fallen tree holding him down like an arm across his breast, seemed to be sleeping peacefully in the sleeping water. * * * * *
