The valleys which the Vaudois have raised into celebrity, lie to the west of Piemont, between the province of Pignerol and Briançon, and adjoining on the other side to the ancient Marquisate of Susa, and that of the Saluces, The capital, La Tour, being about thirty-six miles from Turin, and fourteen from Pignerol. The extent of the valleys is about twelve Italian miles, making a square of about twenty-four French leagues. The valleys are three in number, Luzern, Perouse, and St. Martin. The former (in which the chief town is now Catholic,) is the most beautiful and extensive, and contains the five parishes of Rora, St. Jean, La Tour, Villar, and Bobbi, through the three last of which runs the rapid Pelice, which has its source near the Pra Alp, and throws itself into the Po. The Valley of Perouse is about twelve miles long, chiefly mountainous. It is traversed by the river Cluson, and the villages* on the Italian side of that river, (Pinache, Rivoire, Great and Little Doublon, and Villard,) as well as its chief town Perouse, are entirely inhabited by Roman Catholics. The Vaudois at this time possess only Pramol, Pomaret, and St. Germain. * All those villages were once Vaudois. Between the valleys Luzerne and Perouse, is the parish Prarustin, comprehending Roche Platte, and St. Barthélemi, which belong to neither of them. The Valley of St. Martin is scarcely wider than the bed of the torrent Germanasque, which runs through it, and extends from the Valley of Perouse to that of Queiras in Dauphiné; it contains the parishes of Pral, Ma-neille, and Ville Sèche, of which the former is so elevated, as to be covered with snow during nine months in the year. The other parishes contain each several small villages, and Perrier, which is the capital of the whole valley, is now inhabited by Catholics alone. This valley, which was the scene of the heroic defence of Arnaud's band, is environed by lofty mountains, and rugged rocks, forming the most formidable natural defences; indeed the only passage into it for wheels,* is by a bridge, not far from Perouse, and this pass is so narrow that a few men might defend it against a large force.
