They seemed once more to reach the open air, for they were standing by a lake, yet no sun appeared, and they saw no sky above their heads. A little boat received them, and Zerina steered it diligently forward. It shot rapidly along. On gaining the middle of the lake, little Mary saw that multitudes of pipes, channels, and brooks were spreading from the little sea in every direction. "These waters to the right," said Zerina, "flow beneath your garden, and this is why it blooms so freshly; by the other side we get down into the great stream." On a sudden, out of all the channels, and from every quarter of the lake, came a crowd of little children swimming up; some wore garlands of sedge and water-lily; some had red stems of coral, others were blowing on crooked shells; a tumultuous noise echoed merrily from the dark shores; among the children might be seen the fairest women sporting in the waters, and often several of the children sprang about some one of them, and with kisses hung upon her neck and shoulders. All saluted the stranger; and these steered onward through the revelry out of the lake, into a little river, which grew narrower and narrower. At last the boat came aground. The strangers took their leave, and Zerina knocked against the cliff. This opened like a door, and a female form, all red, assisted them to mount. "Are you all brisk here?" inquired Zerina. "They are just at work," replied the other, "and happy as they could wish; indeed, the heat is very pleasant." They went up a winding stair, and on a sudden Mary found herself in a most resplendent hall, so that, as she entered, her eyes were dazzled by the radiance. Flame-colored tapestry covered the walls with a purple glow; and when her eye had grown a little used to it, the stranger saw, to her astonishment, that, in the tapestry, there were figures moving up and down in dancing joyfulness, in form so beautiful, and of so fair proportions, that nothing could be seen more graceful; their bodies were as of red crystal, so that it appeared as if the blood were visible within them, flowing and playing in its courses. They smiled on the stranger, and saluted her with various bows; but as Mary was about approaching nearer them, Zerina plucked her sharply back, crying: "Thou wilt burn thyself, my little Mary, for the whole of it is fire." Mary felt the heat. "Why do the pretty creatures not come out," asked she, "and play with us?" "As thou livest in the Air," replied the other, "so are they obliged to stay continually in Fire, and would faint and languish if they left it. Look now, how glad they are, how they laugh and shout; those down below spread out the fire-floods everywhere beneath the earth, and thereby the flowers, and fruits, and wine, are made to flourish; these red streams again are to run beside the brooks of water; and thus the fiery creatures are kept ever busy and glad. But for thee it is too hot here; let us return to the garden."
