It seems therefore reasonable to take the entire curve as forming the Cevennes from the depression of the Jarrêt, through which runs the line from Lyons to the coalfields of S. Etienne, as the northern limit, and the Montagne Noire, east of the gap of Revel, by which the road by which Castelnaudary and Castres are linked, as the western termination.
"The Cevennes," says Onésime Reclus, "have this striking feature, that they separate two climates, two vegetations, two natures. To the north and to the west are rain, snow, light fog silvered by the moon, and dense vapours which the sun cannot pierce; and the streams that water the smallest valleys nourish rich green meadows; to the south and east is a blazing sun, are glare, heat, drought, barrenness, dust, the vine, the olive, springs of water few and far between, but where they do issue, copious and clear; here—contrasts of colour, sharp-cut horizons, more beautiful than those of the north.
