A little beyond the last pool the running water suddenly vanished. We looked around to see if it had taken any side passage; but no: it simply disappeared into the earth, although no hole was perceptible in its stony channel. It passed by infiltration into some lower gallery, where the light of a candle had never shone, and is never likely to shine. But we had not reached the end of the cavern, although the passage became so low that we had now really to go down on all-fours in order to proceed. We had not to keep this posture long, for again the roof rose, although to no great height. We walked on about fifty yards or more, and then came to the end. There was no opening anywhere except by the way we entered. We were like flies that had crawled into a bottle, and a very unpleasant bottle it might have proved to us. We noticed—at first with some surprise—that, although there was not a drop of water now in this cul-de-sac, our feet sank into damp sand that had evidently been carried there by water. Sticks were also lying about, and the walls up to the roof were covered with a muddy slime. It was evident that this hole had been filled with water, and not very long ago; probably the last thunderstorm accounted for the signs of recent moisture. While we were talking about this, a strange, muffled, moaning sound reached our ears. We looked at one another over the tops of two candles. 'Thunder,' said my companion. In a few minutes the same dismal moan, long drawn out, came down the cavern, which acted like a speaking-tube between us and the outer world, and conveyed a timely warning. Was it in time? We were not quite sure of this, for as we issued from the cul-de-sac we heard the water coming down the rocks with a very different voice from that which it had not many minutes before. It was clear that the storm was beginning to tell upon the stream, and if the rain had been falling for half an hour, as I had already seen it fall in the Quercy, we might find the work of recrossing those pools and climbing up the cascades anything but cheerful. Already where we had been able to walk on dry stones the water was now up to our ankles. The first cascade to surmount was the worst. We decided to try it on the side opposite to the one by which we descended, for we observed a jutting and highly-polished piece of stalagmite, which promised to help the manoeuvre. One went first, and the other waited, holding the candle. I was in the rear. When my companion had reached the top of the cascade, I threw him the coil of rope—a useless encumbrance, as it happened—and in so doing put out the candle. Before I was sure that I had a dry match upon me, I failed to seize the humour, although I felt the novelty of the situation. During those seconds of uncertainty, the sound of the water—really fast increasing—seemed to become a deafening roar. However, we both had dry matches, and were able to relight our candles; but it might have been otherwise, wet as we were. Without light we should have been as helpless beneath those rocks as mice in a pitcher. The first cascade conquered, we felt much more comfortable, for the picture of being washed into that cul-de-sac had flashed upon the mind of each.
As the next and the next cascade were passed, our spirits rose still more; and when we saw the gray daylight in the distance, our gaiety was quite genuine, and we no longer 'laughed yellow,' as the French phrase it. The stream was rapidly becoming a frantic torrent, but we were not afraid of it now. On reaching the dome, we saw the water pouring over rocks that were dry when we entered, and the clouds seemed to be emptying their rain in frenzy.
An hour later the stream that was lisping so innocently as it threaded its way amongst the stones, and dropped from rock to rock before the storm, sent up a wild roar from the bottom of the valley, and shrieked like a tormented fiend, as it leaped into the black mouth of the Gouffre de Révaillon. Tons of water had probably collected there at the bottom of the gulf. And I, in my shortsightedness, had hoped that the cavern was two or three miles long! I had great reason to be thankful that it ended where it did, for the excitement of adventure would have carried us on, and we might have gone too deep into the earth to hear the thunder.
On emerging from the darkness, we made all the haste we could to reach the nearest inn. The storm was still at its height; the thunder was an almost continuous roar; and the quick lightning-flashes lit up the streaming country. We were quite drenched on reaching a little wayside auberge. Water was soon boiling upon the wood-fire, and having set rheumatism at defiance with steaming glasses of grog, we left for Roc-Amadour, where, on our arrival, we found our friends about to start with lanterns to look for us in the Gouffre de Révaillon.

Noticing one day a low cavern in the rocks beside the Ouysse, I asked if anyone had ever entered it, and was told that a man had done so; that he had found a long, low gallery, which he followed for two or three hundred yards, and then gave up the attempt to reach the end. It was well known that the hole, being on a level with the water, was much used by otters. The desire to explore this cavern becoming strong, I spoke to Decros about the adventure. He was ready to go with me; and so we started, taking with us enough candles to light a ball-room.
On our way over the hills from Roc-Amadour, we passed two dolmens, one of which was in good preservation. There are several hundred of them in the Quercy; and the peasants, who call them pierros levados (raised stones), also 'tombs of the giants' and caïrous, in which last name the Celtic word cairn has been almost preserved, treat them now with indifference, although it is recorded of one of the early bishops of Cahors that he caused a menhir to be broken to pieces because it was an object of idolatrous worship. Those who have been to the trouble of excavating have almost invariably found in each dolmen a cella containing human bones. In some of them flint implements have been discovered; in others iron implements and turquoise ornaments, showing that the tombs, although all alike, belong to different periods. Tumuli are also numerous, but only a few menhirs and traces of cromlechs are to be seen.
Close to the Gouffre de Cabouy, whose outflow forms a tributary of the Ouysse, is a cottage where a man lives whose destiny I have often envied. When he is tired of fishing or shooting, he works in his thriving little vineyard, which he increases every year. The river is as much his own as if it belonged to him; he gets all he wants by giving himself very little trouble, and has no cares. We needed this man's boat for our expedition, and we found it drawn into a little cove beside the ruined mill, long since abandoned. It was a somewhat porous old punt, with small fish swimming about in the bottom; but it was well enough for our purpose. In the warm sunshine of the October afternoon we glided gently down the quiet stream, which is very deep, but so clear that you can see all the water-plants which revel in it, down to the sand and pebbles. Near the banks we passed over masses of watercress, and what might be likened to floating fields of lilies and pond-weed.
It needed no little reflection and expenditure of art to insert the prow of the boat into the mouth of the cavern. What an ugly and uninteresting hole I then thought it! Having run the punt as far as we could into the opening, there still remained about six feet of water to cross before reaching the sandy mud beyond. A plank, however, that we brought with us served as a bridge. The story of the otters was no fable, for here were the footprints of the beasts all over the mud. We lighted candles and looked into the hole. The ground rose and the roof descended, so that to enter it was necessary to lie perfectly flat, and to crawl along by a movement very like that of swimming; then the passage became so small that there was only room for one to go at a time. Neither of us was ambitious to go first, for there was just a chance of an otter seizing the invader by the nose; but neither liked to show the white feather. Each in turn went in a few yards, planted a lighted candle in the mud, and then found some pretext for returning. The hot air of the cavern was almost suffocating, and one felt so helpless flattened against the earth, with the rock pressing so tight upon the back that even to wriggle along was difficult. 'Decros is a native,' thought I, 'and he ought to be used to this kind of work. I will let him understand that he is expected now to do his duty.' In he went again, and planted another candle about a yard in front of the last one. Then he stopped and fired a shot from the revolver that we carried in turn for the otters, and the sound of the detonation seemed to echo in a muffled fashion from the bowels of the earth.
'How many otters have you killed?' I shouted.
