The Happy Forgetters were strictly vegetable eaters, feeding upon the various fungous plants growing in these caverns in great profusion, together with a very nutritious and pleasant tasting jelly made from a hardened gum of vegetable origin which abounded in the crevices of certain rocks. There was still another source of food; namely, the nests of certain shellfish, which they built against the face of the rock, just above the surface of the river. These dissolved in boiling water made an excellent broth, very much like the soup from edible birds’ nests.

The clothes worn by the Happy Forgetters were entirely woven from mineral wool, which in these caverns gave a long and strong fibre of astonishing softness. The Rattlebrains were tolerably good metal-workers too, but contented themselves with fashioning only such articles as were actually necessary for daily use. Their beds were stuffed with dried seaweed and lichens, and Bulger and I passed a very comfortable night.

As I was forbidden to speak aloud, to ask a question, or to walk abroad unless in company with one of the selectmen, I was not sorry when the moment came for the revolving door to be opened. The Happy Forgetters had been led to believe that Bulger and I were a thousand times more dangerous than scaly monsters or black-winged vampires, and hence they held themselves aloof from us, the children hiding behind their mothers, and the mothers peering through crack and crevice at us.

The size of my head inspired them with a nameless dread, and even the half-a-dozen of the younger and more courageous drew aside instinctively to let me pass.

For the first time in my life I was an object of horror to my fellow-creatures, but I had no hard thoughts against them! Timid children of nature that they were, to them I was as terrible an object as the torch-armed demon of destruction would be to us were he let loose in one of our fair cities of the upper world.

And now the guard of Happy Forgetters had halted in front of what seemed to me to be a huge cask fashioned of solid marble, and set one-half within the white wall of the cavern to which they had led me. But on second glance I saw that there was a row of square holes around its bulge, like those in the top of a capstan.

The Happy Forgetters now disappeared for a moment, and when they joined me again each bore in hand a metal bar, the end of which he set in one of these holes, and then at a signal from the leader the huge half-circle of marble began to turn noiselessly around, exactly like a capstan. As each man’s lever came to the wall, he shifted it to the front again. Suddenly, to my amazement, I saw that the great marble cask was hollow, like a sentry box; and you may judge of my feelings, dear friends, upon being politely requested to step inside.

Did I refuse to obey?

Not I. It would have been useless, for was not the whole tribe of Rattlebrains there to lay hands upon me and thrust me in?

So taking off my hat and making a low bow to the little group of Happy Forgetters, I stepped within the hollow cask and Bulger did the same; but not with so good a grace as his master, for, casting an angry glance at the inhospitable dwellers in these chambers of white marble, he growled and laid bare his teeth to show his contempt for them.
