Winding through the sombre solitudes of the Black Forest, we enter the _Vallée d’Enfer_, through the narrow and frowning pass, where MOREAU stemmed the torrent of the Austrian legions, as did Leonidas the myriads of Xerxes in the Straits of Thermopylæ. Little did that able but unfortunate general dream, during his memorable retreat through the Black Forest, that, a few years afterwards, he would meet his death from the mouth of a French cannon, while combatting in the ranks of the Allies.[34] What a curse would _foreknowledge_ prove to man, although so ardently desired by curious and eager mortals! A single glance through the telescope of futurity would render us miserable for life! If good was in store, we would relinquish all efforts to obtain it, as being certain. Every day would seem an age till the happiness arrived—and when it came, all relish for it would be gone. On the other hand, if the glass showed misfortune, sickness, and sorrow in the distance—the prospect would soon drive the wretch insane! Oh blindness to the future wisely given! The DISPOSER of events alone can be the safe depository of prescience. RHINEFALLS. I have always experienced some degree of disappointment at the sight of waterfalls. Where the volume of water is great, the fall is, comparatively trifling—and where the descent is from a great height, then the stream is insignificant. If the NIAGARA could be translated to the Staubach, and the mighty St. Lawrence thundered from a height of eight hundred feet into the valley of Lauterbrunnen, the scene would be awfully grand, and sufficient to startle the Jaungfrau on her icy throne. The Rhine, at Schaffhause, falls about seventy or eighty feet, and is by no means impressive, even when viewed from the camera obscura directly opposite the cataract. We drove from the town on a beautiful moonlight night, and descending the stairs on the left bank of the river, we came close to the water’s edge, and also to that of the fall itself. Here is the spot to see and hear the deluge of water, all sparkling with foam, in the mild light of the moon, come thundering from aloft, and threatening every instant to overwhelm the spectator in the boiling flood. If terror be a source of the sublime, there certainly is some degree of this emotion, mixed with the contemplation of a vast mass of water rolling down from a great height, apparently in a direct course towards us. The roar of the cataract, too, is unlike that of any other sound, and adds considerably to the effect produced on the sense of sight. I do not know how the association of ideas first commenced, but I never see a great waterfall, or a rapid river, without their suggesting themselves as emblems of time or eternity. The torrent rolling along in the same course through countless ages— “In omne volubilis ævum”—
