Rhine, like the mouth of a trumpet; and like the blast of a trumpet is at times the wintry wind through this narrow mountain pass. The blue Alsatian hills rise beyond; and, on a platform or strip of level land, between the Neckar and the mountains, right under the castle, stands the city of Heidelberg; as the old song says, "a pleasant city, when it has done raining." Something of this did Paul Flemming behold, when he rose the next morning and looked from his window. It was a warm, vapory morning, and a struggle was going on between the mist and the rising sun. The sun had taken the hill-tops, but the mist still kept possession of the valley and the town. The steeple of the great church rose through a dense mass of snow-white clouds; and eastward, on the hills, the dim vapors were rolling across the windows of the ruined castle, like the fiery smoke of a great conflagration. It seemed to him an image of the rising of the sun of Truth on a benighted world; its light streamed through the ruins of centuries; and, down in the valley of Time, the cross on the Christian church caught its rays, though the priests were singing in mist and darkness below.
