In many respects the Roman Cave is much more interesting. Its mouth is situated about 150 feet up the cliffs, almost immediately over the cave just described. Quantities of Roman pottery, coins, bones, and other remains, have been discovered there, showing it to be one of the places that sheltered fugitives after the evacuation of Britain by the Roman legions. The entrance is a broad anticlinal arch, and the main passage, high-roofed and ascending gradually, runs east for perhaps a furlong. Then the floor, which has been covered with earth and stones, becomes rugged and rock-strewn, and suddenly we creep through a lowly portal into a high and gloomy chamber, the shadowy corners of whose roof our lights are too feeble to explore. To all appearances this was the end of the cavern; but we had been told that the passage takes a turn here and goes on nearly a quarter of a mile farther. We scanned every part of the walls as far up as we could see, but no accessible opening disclosed itself. In a recess on one side a number of fallen rocks were piled up and wedged between the converging walls. To examine the cavity from a vantage spot, we climbed with a good deal of difficulty to the top of these, and there, to our astonishment, a wide passage sloped up at right angles to the one we had entered by. A curious slit in the wall opened into a perpendicular fissure that was situated right in the roof of the latter, and through the hole we caught a glimpse of our friends following us up. Three men now pushed on up the new passage and entered a chamber whose sole exit was a small and uninviting hole. We crawled and scraped through, and on over sharp stones till at last we could get no farther. We had evidently doubled back over the main cavern, and that we could not be far from the open air was shown by the presence of a bewildered bat, who flew to and fro in the confined space and hit us in the face several times. And in the extreme recess of this narrow branch a steady draught of air blew in through a crevice and nearly put the lights out. Through an oversight we found ourselves at this point reduced to two tapers and a bit, and to economise we kept only one alight at a time, so as to have enough for the return journey. All went well, however, and the sole difficulty we met with was in getting down over the wedged blocks in the big chamber, a climb that proved extremely awkward when taken the reverse way. In many parts of this cavern we noticed prodigious quantities of moths on the walls, as well as many huge spiders. But a more interesting thing was the vegetation naturalised in the caves, examples of which we found in other Mendip caverns as well. It will be advisable to have them examined by a botanical specialist. All I can say about them now is that they consist of extremely slender branching tendrils, some white and translucent, others brownish, thin as cotton.
