We come next to the coalfields that are more or less energetically exploited. Some talk has been about running a special line from them to Marseilles, so as to furnish the vessels with home-produced steam-coal. But the fuel here turned out has not the heating power of the anthracite of Cardiff, and it has proved cheaper to obtain a supply by water from Wales than to employ that which is dug out of the flanks of the Cevennes 150 miles distant.
The Espinouse gives birth on one slope to affluents of the Tarn, that discharges its waters into the Garonne and finally into the Atlantic. On the southern face, which is not a slope but a precipice, through chasms it sends feeders to the Orb that throws its waters into the Mediterranean. The Espinouse is composed of gneiss and schist, penetrated by veins of eruptive matter. Although the actual heights are not great, rarely exceeding 3,300 feet, yet the sheer cliffs, and the manner in which they have been cleft by torrents, gives them a grandeur which makes this portion of the Cevennes well deserving of a visit.
The Monts de Lacaune, almost wholly sterile, link the Cevennes of Hérault to those of Aveyron. The highest crest is the Pic de Montalet, 3,810 feet. They are composed of mica-schists, granite, and porphyry, and stretch in barren plateaux, or monotonous rolling ground, frozen for a great part of the year. The Montagne Noire, on the other hand, is well wooded. From its wretched hamlets come the men who help to gather in the vintage in the more fertile plains.
