Like all the other large caverns in the district, it has its legends. The dwellers in the neighbourhood, who have never cared to explore its recesses, relate that a certain dog put in here found its way out, after many days, at Wookey Hole, having lost all its hair in scrambling through the narrow passages. At Cheddar the same legend is appropriated to the Cheddar cave. At Wookey the dog is said to have travelled back to Cheddar. Some eighteen years ago, while exploring the limestone caves at Llanamynech, on the English border of Montgomeryshire, I met with a similar story. A man playing the bagpipes is said to have entered one of the caves, well provisioned with Welsh mutton, and after he had been in for some time his bagpipes were heard two miles from the entrance, underneath the small town of Llanamynech. He never returned to tell his tale. The few bones found in the cave are supposed to be those which he had picked on the way. This is doubtless another form of the story of the dog; both owe their origin to the vague impression, which most people have, of the great extent of caverns, and both versions are equally current in France and Germany. _The Water-caves of Derbyshire._ The celebrated cavern of the Peak, at Castleton in Derbyshire, presents the same essential character as that of Wookey Hole. It runs into the hill-side at the end of the ravine, and is traversed by a powerful stream of water, which has been met with in driving an horizontal adit in lead-mining at a considerable distance from the entrance, and finally traced to a distant swallow-hole. At a little distance from Buxton a smaller cave, known as Poole’s Cavern, is in part traversed by water, which has found an outlet at a lower level, and allowed of the present entrance being used by the Brit-Welsh (Romano-Celtic) inhabitants of the district as a habitation in the fifth and sixth centuries.[28] There are, besides these, very many others, some known, others unknown, that debouch on the sides of the dales in Derbyshire and Staffordshire, and are all well worthy of examination, since they illustrate not merely the history of the formation of caves, but also have been proved to contain works of art, pottery and flint implements, and the remains of animals, such as the mammoth and rhinoceros. _The Water-caves of Yorkshire._ The caves in the mountain limestone of Yorkshire rival in size those of Carniola, or those of Greece, and they are to be seen in all stages of formation. In their gloomy recesses all the higher qualities of a mountaineer may be exercised, and there is sufficient danger to give a keen zest to their exploration. The mountain streams sometimes plunge into a yawning chasm, locally known as a pot, and at others emerge from the dark portals of a cave in full current. There is, perhaps, no place in the world where the subterranean circulation of water may be studied with better advantage.
