thought possible that the Bonheur could be the stream that issued at Bramabiau, for anything thrown in above never issued below. But the exploration by M. Martel solved the mystery. The stream sinks, filters through the rock, leaving above that which is thrown in, and issues limpid at the cascade that rushes from the entrance.
The descent of the Aigoual on the side of Valleraugue is by a thousand steps hewn in granite and schist, and at the bottom of this is the vegetable garden of the officials of the Observatory.
Valleraugue lies at the bottom of a cirque of mountains at the confluence of the rivers of the Mallet and the Clareau, and it is after their marriage that the united streams assume the name of Hérault. The descent from the Aigoual to Valleraugue occupies two hours, the ascent by the carriage road takes seven. Valleraugue is a busy factory town; the population is mainly engaged in silk spinning and weaving. The place is almost wholly Protestant. This valley of the Hérault as far as Ganges is one of the most active in silk industry in the Cevennes. The vegetation is wholly southern; the hillsides disposed in terraces are planted with vines and mulberries; and ilexes abound, providing the tanneries with their bark. "This valley," says Ardouin Dumazet, "is a synthesis of all the somewhat severe graces of the Cevenol land." The Roman road over l'Hospitalet has been already referred to. It runs from Avignon to Anduze and then ascends the crest above the Garden, and passing under Barre stretches away to Florac. Barre itself occupies a Gallo-Roman oppidum, of which traces remain, and throughout the neighbourhood relics of the Roman tenure of the land are found. After the Col d'Aire de Côte ensues a series of frightful cirques, whose
