There is constant communication, as everybody knows, between Vienna, and Pesth, and Constantinople, by steamboats which touch, as they proceed, at almost all the most important places that lie along the banks of the Danube. Our original intention was to have availed ourselves of one of these; but we found on inquiry, that the navigation was intricate, and the channel of the river so low, that hardly any view was to be obtained from the ship's deck. We determined, therefore, to proceed by land as far as Presburg, and to regulate our future movements according to the aspect of things there, and the information which by its inhabitants might be communicated to us. About seven o'clock, on a bright July morning, we accordingly took our seats in a hired carriage, and were swept along through what are called the Marxer lines, beyond the outermost suburbs of the capital. The country round was, for a while, uninteresting enough. A huge plain was before us, which the heat of the weather had scorched into the semblance of a desert; and there were few objects upon it, of which I can say that they much relieved its monotony. Several villages came, indeed, in our way, and near one of them, called Semmering, a large turreted building attracted our attention. It had once been a summer residence of the Emperor; it is now a powder-magazine, and stands, as our postilion informed us, on the same spot which, during the siege of Vienna in 1529, was covered by the tent of the Sultan Solyman. But we had passed this some time, ere the scenery began to improve. When such improvement did commence, however, it was very complete. The road wound inwards so as to bring us parallel with the river, and to open out a fine view of its waters, which being split up into numerous branches, poured themselves over the plain, and enclosed a countless number of islands within their eddies. Among these, our postilion pointed out that on which Napoleon, by the breaking down of his bridge, was, during the progress of the battle of Asperne, reduced to the utmost extremity,--an extremity out of which nothing but the misplaced confidence of his opponents enabled him to escape. It is an extensive flat, covered along its edges by groves of giant willows; while just beyond it, on the continent, the village spires of Asperne and Essling peer forth from amid screens of thick foliage.
