The figures, stooping over the burning heap, moved occasionally across the darkness, looking like a witch and her familiar spirit, who were conjuring, by uncanny arts, a vision of life, on the strange, white, clean-cut patch of smoke that was defined by the sunlit entrance to the tunnel. The witch stirred, and her familiar added fuel, while behind them the smoke, rising and curdling, formed the mysterious background of light: opaque, and yet in a state of incessant movement, as of some white raging fire, thinner and more deadly than any ordinary earthly element, that seemed to sicken and flicker in the blast of a furnace, and then rushed upwards, and coiled and rolled across the tunnel's mouth. Presently, as a puff of wind swept away part of the smoke, a miraculous tinge of rosy colour appeared, changing, as one caught it, into gold, and presently to a milky blue, then liquid green, and a thousand intermediate tints corresponding to the altering density of the smoke--and then! Hadria caught her breath--the blue and the red and the gold melted and moved and formed, under the incantation, into a marvellous vision of distant lands, purple mountains, fair white cities, and wide kingdoms, so many, so great, that the imagination staggered at the vastness revealed, and offered, as it seemed, to him who could grasp and perceive it. Among those blue deeps and faint innumerable mountain-tops, caught through a soft mist that continually moved and lifted, thinned and thickened, with changing tints, all the secrets, all the hopes, all the powers and splendours, of life lay hidden; and the beauty of the vision was as the essence of poetry and of music--of all that is lovely in the world of art, and in the world of the emotions. The question that had been debated so hotly and so often, as to the relation of the good and the beautiful, art and ethics, seemed to be answered by this bewildering revelation of sunlit smoke, playing across the face of a purple-tinted rock, and a few feet of grass-edged pathway. "Come and see what visions you have conjured up, O witch!" cried Hadria. Algitha gave a startled exclamation, as the smoke thinned and revealed that bewildering glimpse of distant lands, half seen, as through the atmosphere of a dream. An exquisite city, with slender towers and temples, flashed, for a moment, through the mist curtain. "If life is like that," she said at length, drawing a long breath, "nothing on this earth ought to persuade us to forego it; no one has the right to hold one back from its possession." "No one," said Hadria; "but everyone will try!" "Let them try," returned Algitha defiantly. CHAPTER III.
