Kaub, a Palatine town on the right bank of the river, is also fortified, and claims a toll upon the Rhine, notwithstanding its neighbourhood to Bacharach; an oppression, of which the expence is almost the least inconvenience, for the toll-gatherers do not come to the boats, but demand, that each should stop, while one at least of the crew goes on shore, and tells the number of his passengers, who are also sometimes required to appear. The officers do not even think it necessary to wait at home for this information, and our boatmen had frequently to search for them throughout the towns. So familiar, however, is this injustice, that it never appeared to excite surprise, or anger. The boatman dares not proceed till he has found and satisfied the officers; nor has he any means of compelling them to be punctual. Ours was astonished when we enquired, whether the merchants, to whom such delays might be important, could not have redress for them. The stay we made at Kaub enabled us, however, to perceive that fine slate made a considerable part of its traffic. The Rhine, at Bacharach and Kaub, is of great breadth; and the dark mountains, that ascend from its margin, form a grand vista, with antient chateaux still appearing on the heights, and frequent villages edging the stream, or studded among the cliffs. Though the district of the Rheingau, the vines of which are the most celebrated, terminated some miles past, the vineyards are scarcely less abundant here, covering the lower rocks of the mountains, and creeping along the fractures of their upper crags. These, however, sometimes exhibit huge projecting masses and walls of granite, so entire and perpendicular, that not an handful of soil can lodge for the nourishment of any plant. They lie in vast oblique strata; and, as in the valley of Andernach, the angles of the promontories on one shore of the river frequently correspond with the recesses on the other. OBERWESEL Is another town, supported by the manufacture and trade of wines, which are, however, here shared by too many places to bestow much wealth singly upon any. Wine is also so important a production, that all the Germans have some degree of connoisseurship in it, and can distinguish its quantities and value so readily, that the advantage of dealing in it cannot be great, except to those, who supply foreign countries. The merits of the different vineyards form a frequent topic of conversation, and almost every person has his own scale of their rank; running over with familiar fluency the uncouth names of Johannesberg, Ammanshausen, Hauptberg, Fuldische Schossberg, Rudesheim, Hockheim, Rodtland, Hinterhauser, Markerbrunner, Grafenberg, Laubenheim, Bischeim, Nierstein, Harscheim and Kapellgarren; all celebrated vineyards in the Rheingau. The growth and manufacture of these wines are treated of in many books, from one of which we translate an account, that seems to be the most comprehensive and simple.
