So together we set off over hill and dale and came to the Mummelsee; and that before we had gone six hours, for my dad was as lively as a cricket and as good a traveller as any young man. And there we consumed what meat and drink we had brought with us, for the long journey and the high mountain on which the lake lieth had made us both hungry and thirsty. So having refreshed ourselves I did inspect the lake, and found lying in it certain hewn timbers which my dad and I took to be the remains of the Würtemberg raft: and I by geometry took or estimated the length and breadth of the water (for ’twas far too wearisome to go round the lake and measure it by paces or feet), and entered the dimensions, by means of the scale of reduction, in my tablets. And having done this, the sky being completely clear and the air windless and calm, I must needs try what truth was in the legend that a storm would arise if any should throw a stone into the lake; having already found those stories I had heard, how the lake would suffer no trout to live in it, to be true, by reason of the mineral taste of the waters. So to make trial of this, I walked along the lake to the left, where the water, which elsewhere is as clear as a crystal, doth begin, by reason of the monstrous depth, to show as black as coal, and therefore is so dreadful of appearance that the mere look of it doth terrify. And there I began to cast in stones as great as I could carry; my foster-father or dad not only refusing to help me, but warning and begging me to give over, as much as in him lay: but I went busily on with my work, and such stones as by reason of their size and weight I could not carry, I rolled down till I had cast more than thirty such into the lake. Then began the sky to be covered with black clouds, in which terrible thundering was heard, so that my dad, which stood on the other side of the lake by the outlet, lamenting over my work, cried out to me that I should escape, lest we be caught by the rain and the dreadful storm, or even a worse mishap chance to us. But in despite of all I answered him, “Father, I will stay and await the end even though it rained pitchforks.” “Yea, yea,” answered he, “ye act like all madcap boys, that care not if the world perish.”
But I, while I listened to his scolding, turned not mine eyes away from the depths of the lake, expecting to see certain bladders or bubbles rising up from the bottom, as is wont to happen when stones are thrown into deep water whether still or running. Yet saw I naught of the kind, but was ware of certain creatures floating far down in the depths, which in form reminded me of frogs, and flitted about like sparks from a mounting rocket which in the air doth work its full effect: and as they came nearer and nearer to me they seemed to grow larger and more like to the human form: at which at first great wonder took hold of me, and at last, when I saw them hard by me, a great fear and trembling. “Ah,” said I then to myself in my terror and wonder, and yet so loud that my dad, that stood beyond the lake, could hear me, though the noise of the thunder was dreadful, “how great are the wondrous works of the Creator! yea, even in the womb of the earth and the depths of the waters!” And scarce had I said these words when one of these sylphs appeared upon the waters and answered me, “Aha, and thou dost acknowledge that before thou hast seen aught thereof: what wouldst say if thou wert for once in the Centrum Terrae and beheldest our dwelling which thy curiosity hath disturbed?”
Meanwhile there rose up here and there more of such water-spirits, like diving birds, all looking upon me and bringing up again the stones I had cast in, which amazed me much. And the first and chiefest among them, whose raiment shone like pure gold and silver, cast to me a shining stone of the bigness of a pigeon’s egg and green and transparent as an emerald, with these words: “Take thou this trinket, that thou mayst have somewhat to report of us and of our lake.” But scarce had I picked it up and pocketed it when it seemed to me the air would choke or drown me, so that I could not stand upright but rolled about like a ball of yarn, and at last fell into the lake. Yet no sooner was I in the water than I recovered, and through the virtue of the stone I had upon me could breathe in water instead of air: yea, I could with small effort float in the lake as well as could the water-spirits, yea, and with them descended into the depths; which reminded me of nothing so much as of a flock of birds that so descend in circles from the upper air to light upon the ground.
But my dad having beheld this marvel in part (namely, so much of it as was done above the water), made off from the lake and home again as
