The next cave also is of minor interest to the speleologist, although it contains many curious sights. It is called "Gough's Old Cavern," and its entrance is close to the mouth of the Great Cavern. It is an ascending cleft, apparently not linked at present with the other caves, although it was once probably a sloping aven draining into the big series of caverns that have been gradually cut back by the falling in of the defile. Whoever likes such things may find here plenty of those freaks and alleged similitudes that puzzle and delight the ordinary sightseer. On a stalagmite excrescence nicknamed the "Ribs of Beef" we had the luck to see a far more interesting phenomenon. The calcite mass was clustered over with a number of motionless black objects, which we found to be roosting bats, hanging head downwards by their claws. They were not disturbed in the least by our presence, and one that was lifted off gently just showed his teeth and claws, and clung on again as fast as ever when replaced on the rock to resume his patient sleep. A photograph of this curious sight was obtained by means of the flashlight. At the head of the cave are several incrusted grottoes, where the process of deposition is still going on, roof and walls streaming with moisture. This part is not unlike the show places in the Bagshawe Cavern in the Peak of Derbyshire. 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.
