To these particulars it may be useful to add, that one of the surest proofs of the purity of Rhenish is the quick rising and disappearance of the froth, on pouring it into a glass: when the beads are formed slowly and remain long, the wine is mixed and factitious. OBERWESEL. The account of which has been interrupted by this digression, is the first town of the Electorate of Treves, on this side, to which it has belonged since 1312, when its freedom as an imperial city, granted by the Emperor, Frederic the Second, was perfidiously seized by Henry the Seventh, and the town given to him by his brother Baldwin, the then Elector. The new Sovereign enriched it with a fine collegiate church, which still dignifies the shore of the river. If he used any other endeavours to make the prosperity of the place survive its liberties, they appear to have failed; for Oberwesel now resembles the other towns of the Electorate, except that the great number of towers and steeples tell what it was before its declension into that territory. The Town-house, rendered unnecessary by the power of Baldwin, does not exist to insult the inhabitants with the memory of its former use; but is in ruins, and thus serves for an emblem of the effects, produced by the change. Between Oberwesel and St. Goar, the river is of extraordinary breadth, and the majestic mountains are covered with forests, which leave space for little more than a road between their feet and the water. A group of peasants, with baskets on their heads, appeared now and then along the winding path, and their diminutive figures, as they passed under the cliffs, seemed to make the heights shew more tremendous. When they disappeared for a moment in the copses, their voices, echoing with several repetitions among the rocks, were heard at intervals, and with good effect, as our oars were suspended. Soon after passing the island of Sand, we had a perspective view of St. Goar, of the strong fortress of Rhinfels, on the rocks beyond, and of the small fortified town of Goarhausen, on the opposite bank. The mountains now become still more stupendous, and many rivulets, or _becks_, which latter is a German, as well as an English term, descend from them into the river, on either hand, some of which, in a season less dry than the present, roar with angry torrents. But the extreme violence, with which the Rhine passes in this district, left us less leisure than in others to observe its scenery. ST. GOAR.
