It was still early, though we had loitered a good deal by the way, to study views and examine ruins, when we drew near the fort-environed town of Coblentz. The bridge across the Moselle was soon passed, and we again found ourselves in this important station. The territory opposite the city belongs to the duchy of Nassau, but enough has been ceded to the King of Prussia to enable him to erect the celebrated Ehrenbreitstein, which is one of the strongest forts in the world, occupying the summit of a rocky height, whose base is washed by the Rhine, and whose outworks are pushed to all the neighbouring eminences. The position of Coblentz, at the junction of the Rhine and the Moselle, the latter of which penetrates into the ancient electorate of Treves, now belonging to Prussia, may render it an important station to that power, but it does not strike me as military. The enemy that can seize any one of its numerous outworks, or forts, must essentially command the place. As at Genoa, it seems to me that too much has been attempted to succeed. Last night we had a convent that was a parallelogram of six hundred feet by three hundred, all to ourselves; while this night we were crowded into a small and uncomfortable inn that was overflowing with people. The house was noisy and echoish, and not inappropriately called the "Three Swiss." We crossed the river by the bridge of boats, and ascended the opposite hill to enjoy the view. There was another island up the stream, with a ruined convent, but unhappily it was not an inn. The Rhine is a frontier for much of its course, washing the shores of France, Darmstadt, Bavaria, Baden, Nassau, Prussia, &c., &c., for a long distance, and permanent bridges are avoided in most places. The floating bridges, being constructed of platforms laid on boats, that are united by clamps, can be taken apart, and withdrawn, to either shore, in an hour or two.
