The valley of the Dor is therefore shut in either by precipitous volcanic walls, or is guarded by sombre woods. Once on the tops of the plateaux, and you may ride a whole day on unbroken turf; or, if you penetrate within the forest lands, you may wander for any time you please, days or weeks, without seeing either their beginning or their end. On the summits of the mountains around, snow is to be found in patches, even in the hottest days of summer; and as the Pic de Sancy is more than six thousand feet above the level of the sea, almost every gradation of climate is to be found amongst these lonely hills. In the dog-days, the valleys are so hot that you gladly escape to the upper lands for air and coolness; but the winter sets in, in October, and the valley of the Dor is then covered deep with snow for many a long month. The Dor itself is a pleasant lively stream: it can boast of some picturesque falls here and there, but it is commonly a "brawling brook," winding about at its pleasure; allowing itself to be forded every now and then; and producing plenty of small trout for those who like to waste their time in fishing. The urchins of the peasant tribe know how to get these finny creatures more cannily than the professed angler; you may see them on a summer's morning wading up the stream, and hunting under every stone, and in each little pool, for the objects of their search. As soon as they see a trout, they drive it into little convenient nooks that they know of, and there--how they manage it nobody knows, but the result is certain--they catch them with their hands or knock them on the head with their sticks; and will always produce you a respectable dish at a few hours' notice. About a couple of leagues below the Pic de Sancy, towards the west, one of the plateaux on the northern side of the valley assumes an exceedingly bold and regular appearance; it is called the Plateau de l'Angle--perhaps from its making, by an abrupt termination, the corner of two valleys; and it towers out like a promontory at sea, soaring some four or five hundred feet above the bed of the river. Not very far from where this plateau is cut off--a mile or so--there is a bold cascade dashing over its side, and carrying off the superfluous waters of a pool and morass higher up in the bosom of the mountains. Here the basaltic precipice is hollowed out into a circling chasm, and over its black face rushes the impetuous stream upon a huge chaos of rocks and debris below, foaming and roaring until it finds its way into the Dor far down in the valley at its foot. A few hundred feet to the westward of this cascade, and at the lowest part of the precipitous columnar cliff, burst forth several copious fountains of hot mineral waters, half-way to boiling heat when they leave their rocky cells, and ever keeping up the same degree both of heat and quantity. These are the springs which give celebrity to the place, and constitute the baths of Mont Dor.
