Immediately behind the village of Mialet, under the side of the hill, is another large cavern, with other grottoes branching out of it, capable, on an emergency, of accommodating the whole population. This was used by Roland as his principal magazine. But perhaps the most interesting of these caves is the one used as a hospital for the sick and wounded. It is situated about a mile above Mialet, in a limestone cliff almost overhanging the river. The approach to it is steep and difficult, up a footpath cut in the face of the rock. At length a little platform is reached, about a hundred feet above the level of the river, behind which is a low wall extending across the entrance to the cavern. This wall is pierced with two openings, intended for two culverins, one of which commanded the road leading down the pass, and the other the road up the valley from the direction of the village. The outer vault is large and roomy, and extends back into a lofty dome-shaped cavern about forty feet high, behind which a long tortuous vault extends for several hundred feet. The place is quite dry, and sufficiently spacious to accommodate a large number of persons; and there can be no doubt as to the uses to which it was applied during the wars of the Cevennes. The person who guided us to the cave was an ordinary working man of the village--apparently a blacksmith--a well-informed, intelligent person--who left his smithy, opposite the Protestant temple at which our pony-cart drew up, to show us over the place; and he took pride in relating the traditions which continue to be handed down from father to son relating to the great Camisard war of the Cevennes. CHAPTER VII. EXPLOITS OF CAVALIER. The country round Nismes, which was the scene of so many contests between the Royalists and the Camisard insurgents at the beginning of last century, presents nearly the same aspect as it did then, excepting that it is traversed by railways in several directions. The railway to Montpellier on the west, crosses the fertile valley of the Vaunage, "the little Canaan," still rich in vineyards as of old. That to Alais on the north, proceeds for the most part along the valley of the Gardon, the names of the successive stations reminding the passing traveller of the embittered contests of which they were the scenes in former times: Nozières, Boucoiran, Ners, Vezenobres, and Alais itself, now a considerable manufacturing town, and the centre of an important coal-mining district.
