CLIFF REFUGES
the cavern had been reached. A tradition existed in the Vers valley that at one time there had been a tower at the foot of the rock, and old men remembered the removal of some of its ruins for the construction of a mill. By digging, the foundations of the tower were disclosed. It had been square and measured 44 feet on each side. It had stood about 60 feet high, and had been topped with a lean-to tiled roof resting against the uppermost beam in the cave and thereby masking it.[1]
A somewhat similar cave is that of Boundoulaou in the Causse de Larzac (Lozère). Although this has an opening in the face of the precipice, which is partly walled up, it can be entered from another and more accessible cave. At a considerably lower level flows a stream that at one time issued from it, but has worked its way downwards, and now gushes forth many feet below. However, apparently in times of heavy rain, the overflow did burst forth from the upper cavern, for in it were found the skeletons of a whole family that had perished on one such occasion.
At nearly 180 feet up the face of a sheer perpendicular cliff near Milan is the cave of Riou Ferrand, 45 feet below the brow of the precipice. The mouth of the grotto is partly blocked by a well-constructed wall. It has been entered from above and explored. It yields delicately fine pottery and a spindle-whorl, so that a woman must have taken refuge here, and here sat spinning and looking down from this dizzy height on the ruffians ravaging the valley below and setting fire to her house. Bones of sheep and pigs in the cave showed that it, had been tenanted for some time, and tiles of distinctly Roman character indicated the period of its occupation. The only possible means of entering this cavern is, and was, by a rope or a ladder from above.[2]
