which may be rendered, "If the cloud comes from the Aigoual, take your oxen and go to the stable. If the cloud comes from the Lozère, take your oxen and go to the furrow."
The Aigoual is a granitic mass, reaching to 5,140 feet, whereas the Roc de Malpertus, in the Mont Lozère group, rises to 5,520 feet, but this latter is far less suitable for meteorologic observation. Around the Aigoual erosion has formed a labyrinth of gorges and profound valleys, in the beds of which race torrents impatient to reach lower levels.
From the side of Merueys, the Aigoual does not present by any means an imposing appearance. It is a domed green mass, on the top of which gleam white the walls of the Observatory. From the side of La Luzette it bears some resemblance to a huge antediluvian monster in a crouching posture with fore paws extended.
On the south side the Aigoual is rugged and abrupt. Its precipices descend to great depths. The stream of the Claron there in a succession of falls drops to the depth of 3,000 feet in a very short distance.
The Aigoual has two heads, one of these, La Fayède, looking towards the sun-bathed basin of the Rhône; the other, that of the Hort Dieu, the loftiest but the least picturesque. Between these is a coombe, watered by a thousand springs that ooze from the turf and nourish a rich vegetation. It is this coombe really which is the Garden of God, as the natives term it.
On the one side the Aigoual rises out of mulberry and chestnut woods, torn and precipitous; on the other it is smooth and velvety, wooded only with distorted beech. It has been ravaged by the merciless axe of the peasant that has left it bald and desolate. From the summit a superb view is obtained of the tossed and torn ridges of schist mountain, some rounded, but furrowed like the face of one very aged, some starting up into peaks, some stretching out saw-like ridges, some flat-headed, according to the nature of the rock of which composed. To the north rises the Tarnon that passes by Florac, below which it enters the Tarn. A little to the north-east is the Signal de l'Hospitalet, and beyond Barre des Cévennes. The old Roman road ran over this latter col to penetrate into the heart of the Cévennes; it kept to the crest, commanding glorious views.
The Aigoual should be ascended from Meyrueis, a little town half the population of which is Protestant. Near it, and on the way, is the Renaissance castle of Roquedols.
Here one passes abruptly from the limestone to the granite, and at once notes a corresponding difference in the flora. Among the limestone rocks the pinks show as drops of blood. On the granite are none. The fields by Roquedols are white with narcissus poeticus, not a flower of that bulb is in the calcareous fields. The distance from Meyrueis to the Aigoual is just over nineteen miles, and a carriage should be taken at least as far as to Camprieu, where Bramabiau demands a visit. On the top of the Aigoual a dinner and a bed may be obtained at the Observatory. Bramabiau may also be visited from Le Vigan. The rivulet of the Bonheur, that descends from the Col de Séyrerède near the Aigoual, after flowing over granite and schist, encounters a mass of Dolomitic limestone, through which it has bored a channel for a distance of 1,200 feet. The tunnel through which it flows is in one place open to the sky through the falling in of the roof. The name Bramabiau given to this cavern traversed by a stream is onomatopœic, and signifies the bellowing of a bull, as the water in time of flood gives forth angry sounds.
Nothing surprises one more than the apparent inadequacy of the means to the end attained. The Bonheur is but a small stream, yet the work it has achieved is tremendous. But it must be borne in mind that where stands Camprieu was once a lake, the water held back by the barrier of limestone, and that the accumulated force was brought to bear on the rock to effect this tunnel of drainage. Moreover, the rock itself was full of holes like a sponge, with large vaults like huge bubbles in its interior, so that it was not a solid mass through which the stream had to bore its way. It was further aided by several springs rising within the rock, all working in their several courses to effect their escape.
