The number of fortresses here, over which Rhinfels is in every respect paramount, seem to be the less necessary, because the river itself, suddenly swoln by many streams and vexed by hidden rocks, is a sort of natural fortification to both shores, a very little resistance from either of which must render it impassable. Whether the water has a subterraneous passage from Bingen hither or not,--there are occasionally agitations in this part, which confound the skill of naturalists; and the river is universally allowed to have a fall. Near St. Goar, a sudden gust of wind, assisted by the current, rendered our boat so unmanageable, that, in spite of its heaviness and of all the efforts of the watermen, it was whirled round, and nearly forced upon the opposite bank to that, on which they would have directed it. St. Goar is a place of great antiquity. A dispute about the etymology of its name is remarkable for the ludicrous contrariety of the two opinions. One author maintains, that it is derived from an hermit named Goar, who, in the sixth century, built a small chapel here. Another supposes that Gewerb, the name of a neighbouring fall in the Rhine, has been corrupted to Gewer, and thence to Goar; after which, considering that there is an island called _Sand_ in the river, and that a great quantity of that material is hereabouts thrown up, he finds the two words combine very satisfactorily into a likeness of the present denomination. The former opinion is, however, promoted by this circumstance, which the advocates of the latter may complain of as a partiality, that a statue of St. Goar is actually to be seen in the great church, founded in 1440; and that, notwithstanding the robberies and violences committed in the church by a Spanish army, the following inscription is still entire: S. GOAR MONACHUS GALLUS OBIIT 611. St. Goar is one of the largest places we had yet passed, and has a considerable share of the commerce carried on by the Rhine. Having in time of war a numerous garrison, and being a little resorted to on account of its romantic situation, it has an air of somewhat more animation than might be expected, mingling with the gloom of its walls, and the appearance of decay, which it has in common with other German towns. We were here required to pay the fifth toll from Mentz, and were visited by a Hessian serjeant, who demanded, that our names and condition should be written in his book. These being given, not in the Saxon, but the Roman character, he returned to require another edition of them in German; so that his officer was probably unable to read any other language, or characters. This being complied with, it seemed, that the noble garrison of St. Goar had no further fears concerning us, and we were not troubled by more of the precautions used, "Lest foul invasion in disguise approach."
