Darmstadt is one of those towns which are laid out on so large a scale as to appear mean. This is a common fault, both in Germany and America; for the effect of throwing open wide avenues, that one can walk through in five minutes, is to bring the intention into ludicrous contrast with the result. Mannheim is another of these abortions. The disadvantage, however, ends with the appearance, for Darmstadt is spacious, airy, and neat; it is also well-built. The ancient Landgraves of Hesse Darmstadt have become Grand Dukes, with a material accession of territory, the present sovereign ruling over some 700,000 subjects. The old castle is still standing in the heart of the place, if a town which is all artery can be said to have any heart, and we walked into its gloomy old courts, with the intention of examining it; but the keeper of the keys was not to be found. There is a modern palace of very good architecture near it, and, as usual, extensive gardens, laid out, so far as we could perceive from the outside, in the English taste. A short distance from Darmstadt, the Bergestrasse (mountain road) commences. It is a perfect level, but got its name from skirting the foot of the mountain, at an elevation to overlook the vast plain of the Palatinate; for we were now on the verge of this ancient territory, which has been merged in the Grand Duchy of Baden by the events of the last half century. I may as well add, that Baden is a respectable state, having nearly 1,300,000 subjects. The Bergestrasse has many ruins on the heights that overlook it, though the river is never within a league or two of the road. Here we found postilions worthy of their fine track, and, to say the truth, of great skill. In Germany you get but one postilion with four horses, and, as the leaders are always at a great distance from those on the pole, it is an exploit of some delicacy to drive eight miles an hour, riding the near wheel-horse, and governing the team very much by the use of the whip. The cattle are taught to travel without blinkers, and, like men to whom political power is trusted, they are the less dangerous for it. It is your well-trained animal, that is checked up and blinded, who runs away with the carriage of state, as well as the travelling carriage, and breaks the neck of him who rides. It was quite dark when we crossed the bridge of the Neckar, and plunged into the crowded streets of Heidelberg. Notwithstanding the obscurity, we got a glimpse of the proud old ruin overhanging the place, looking grand and sombre in the gloom of night.
