I could not believe it at first, and thought it must be occasioned by the sun; I therefore visited the springs at different times, sometimes when the sun shone brightly, sometimes when it was obscured by clouds, once even after its setting; but the colouring always remained the same. One may fearlessly approach the brink of these springs. The platform which projects directly from them, and under which one can see in all directions, is indeed only a thin ledge of rock, but strong enough to prevent any accident. The beauty consists, as I have said, in the magical illumination, and in the transparency, by which all the caves and grottoes to the greatest depths become visible to the eye. Involuntarily I thought of Schiller's _Diver_. {40} I seemed to see the goblet hang on the peaks and jags of the rock; I could fancy I saw the monsters rise from the bottom. It must be a peculiar pleasure to read this splendid poem in such an appropriate spot. I found scarcely any basins of Brodem or coloured waters. The only one of the kind which I saw was a small basin, in which a brownish-red substance, rather denser than water, was boiling. Another smaller spring, with dirty brown water, I should have quite overlooked, if I had not so industriously searched for these curiosities. At last, after long waiting, on the second day of my stay, on the 27th June, at half-past eight in the morning, I was destined to see an eruption of the Geyser in its greatest perfection. The peasant, who came daily in the morning and in the evening to inquire whether I had already seen an eruption, was with me when the hollow sounds which precede it were again heard. We hastened out, and I again despaired of seeing any thing; the water only overflowed as usual, and the sound was already ceasing. But all at once, when the last sounds had scarcely died away, the explosion began. Words fail me when I try to describe it: such a magnificent and overpowering sight can only be seen once in a lifetime. All my expectations and suppositions were far surpassed. The water spouted upwards with indescribable force and bulk; one pillar rose higher than the other; each seemed to emulate the other. When I had in some measure recovered from the surprise, and regained composure, I looked at the tent. How little, how dwarfish it seemed as compared to the height of these pillars of water! And yet it was about twenty feet high. It did, indeed, lie ten feet lower than the basin of the Geyser; but if tent had been raised above tent, these ten feet could only be deducted once, and I calculated, though my calculation may not be correct, that one would need to pile up five or six tents to have the height of one of the pillars. Without exaggeration, I think the largest spout rose above one hundred feet high, and was three to four feet in diameter.
