CLIFF REFUGES
cross pieces of metal, either bronze or iron. This may be the remains of a roof or a floor destined to supplement the insufficiency of the overhanging rock—and of the size of the fissure, so as to convert it into some sort of shelter. To study the matter, a ladder of nearly 50 feet would be needed (to be let down from above). In the absence of all tradition, these beams of Les Fadarelles remain a mystery. As the face of the cliff is absolutely smooth above the opening, below and on both sides, completely devoid of anything like a ledge by which access could be obtained to it, the question presents itself to one for the third time, as at Boundoulaou and at Riou Ferrand, were these cliff-dwellers in the Gausses like those in the Cañon of Colorado, or has the demolition of ledges by weather on these limestone cliffs proceeded with great rapidity?"
Two apparently inaccessible caves, that have been the habitation of man as a temporary refuge, and that have been explored by M. Philibert Lalande, show that there was a way in which some, though by no means all, were reached. The grottoes of Puy Labrousse near Brive, comprising five or six chambers, have isolated from the rest one that opens in the face of a sheer precipice at a considerable height above the valley. It can be entered only from behind, by a very small oval opening, preceded by a gallery very narrow, and masked at the entrance by enormous rocks, and which could be barricaded by stout beams, hollows for the reception of which are visible.
The other is at Soulier-de-Chasteaux on the Couze, an affluent of the Vézère. Here are two caverns excavated by the hand of man. The most curious is on the right bank near the top of a Jurassic cliff that is absolutely precipitous, and this also can be entered a retro. A narrow path leads to an opening very small, excavated in the vault of the cavern, through which a man could squeeze himself so as to descend into it by means of a ladder. The gaping mouth
