"It would indeed have been a very pleasant walking tour, thanks to that unlikeness of our natures which produces the most harmonious companionship, had it not been for the monotony of the scenery through which our way lay. The subterranean passages, illumined by our lamps, were sometimes vast, sometimes narrow, sometimes rounded like the naves of the cathedrals, sometimes square, angular, and mean, like the corridors of workhouses. But they presented no spectacle of great variety. When he had said, 'Look, stone! Look, clay! Look, sand!' we had said everything, because we had seen everything.
"It was on the afternoon of the fourteenth day that M. Longuet embarked on a subject of conversation extremely distasteful to me, the edible qualities of the human body. I tried gently to divert him from it; but it appeared to have become one of his fixed ideas; and he harped on it for two very tedious hours. That evening I halted for supper on the banks of a stream, nearly eighteen inches wide, which ran across the passage we were in; and after supper I suggested that, before retiring for the night, he should for once glut his sportsman's ardour.
"Though indeed he had no hooks, he fell to his angling with the liveliest eagerness. We turned the light of our lamp on to the waters of the stream, and presently out of the hole in the wall from which it issued, there came swimming a little fish. Then we found that hooks were unnecessary in the sport of the Catacombs. Owing to the fact that the little fish had no eyes, M. Longuet was able to lay his hand on the bed of the stream, which was, perhaps, at that point three inches deep, and when the little fish came swimming over it, to jerk up his hand and fling it on the bank. We examined his catch in the light of our lamp; but I was unable to say whether it was an Asellus Aquaticus or a Cyclops Fimbriatus.
"In the course of the next quarter of an hour we caught three more of these little fishes (they were nearly four inches long); then, at the sight of fresh fish, a wolfish gleam came into M. Longuet's eyes; and he suggested that we should repeat the supper we had only just finished. After his distasteful conversation of the afternoon, I made no objection. But with his ineradicable middle-class instinct he complained that we had no means of cooking our catch. I explained to him that our early ancestors, the cave-men, probably ate most of their food raw, and whatever else we were, we were, at the moment, undoubtedly cave-men. With this new intellectual alertness, acquired by following the method of M. Fletcher of the United States, he saw my point. We cleaned the fish with the knife of Signor Petito and ate them. They were delicious.
"But, as I should have foreseen, so much rich food coming suddenly after the rational diet on which we had subsisted during the last fortnight was too much for us, and for several hours we suffered the most acute pangs of indigestion. Moreover, with the greedy haste of gourmands, we had not timed ourselves over the meal, and had eaten the fish far too quickly. However, no experience is wasted on a rational man; and I realised that one Asellus Aquaticus, after ham, is enough for the logical Fletcherite.
"After the passing of our indigestion, we slept soundly; and the next morning we resumed our journey entirely free from any anxiety: it might take us six months, or it might take us a year, but sooner or later we should find the Ossuary and the exit from the Catacombs, sustained in our task by the Asellus Aquaticus. Indeed it was extremely improbable that it would take us more than a few days longer, for since I had never missed a chance of taking a passage which appeared to lead back to our starting-point, we must necessarily have drawn further and further from it.
"This expectation was realised sooner than I expected, for on the night of the seventeenth day, just as, at the close of a very interesting discussion on the neglect of the logical faculty by the great majority of men, we had turned our thoughts to supper and sleep, we were suddenly confronted by two skeletons.
"They were fastened against the wall on either side, and an arm of either, like the arm of a finger-post, pointed down the passage ahead.
