On the face of an enormous basaltic rock is a remarkable cave divided into several chambers, and large enough to contain all the villagers. It was employed as a place of refuge during the wars of feudal times, and again in those of religion. Access to it is not easy. As the railway reaches the watershed, barricades on both sides protect it from snow-drifts. Luc is passed, having an old castle on a rock, the donjon braced to sustain a colossal statue of the Virgin. Then the train halts at La Bastide, where is a branch line to Mende.
The Trappist monks have an establishment near this on these bleak heights. Their buildings are tasteless. Hitherto the monks have been left unmolested by Government, due possibly to the fact that they receive and examine the silkworm moths that have laid their eggs, sent to them from great distances round, to examine if they are free from the disease that so fatally threatened the silk industry in the Cevennes.
The breaking out of this complaint caused consternation some years ago, and M. Pasteur was sent down to investigate it. He found that no remedial efforts availed, and that the sole way of getting rid of the disorder was to stamp it out. Accordingly every moth after it has laid its eggs is enclosed along with the seed that has been deposited in a muslin bag and sent to be inspected. Each bag is numbered and ticketed with the name of the sender. The body of the moth is pounded up and submitted to examination under a powerful microscope, and this reveals the presence of the germs of fibrine if they exist. Should these be detected, the eggs of that particular moth are destroyed by fire.
In addition to this service rendered by the Trappists,
