At least, this was the way I felt after I had been presented to the learned Barrel Brow, and so the next time I called upon him I waited patiently for him to finish reading the four books in front of him, and then I said,—

“Be pleased, dear Master, to tell me something concerning the early history of thy people, and to explain to me how they came to make their way down into this underground world.”

“Ages and ages ago,” wrote the learned Barrel Brow, “my people lived upon the shores of a beautiful land with a vast ocean to the north of it, and in those days they had the same senses as the other people of the upper world. It was a very fair land, indeed, so fair that, in the words of the ancient chronicles, the sun looked in vain for a fairer. Its rivers were deep and broad, its plains were rich and fertile, and its mountains stored full of silver and gold and copper and tin, and so easily mined were these metals that our people became famous as metal workers; so deft in their workmanship that the other nations from far and near came to us for swords and shields and spear heads and suits of armor and table service and armlets and bracelets and, above all, for lamps most gloriously chased and carved to hang in their palaces and temples. And so we were very happy, until one terrible day the great round world gave a twist and we were turned away from the sun, so that its rays went slantingly over our heads and gave us no warmth.

“Ah me, I could weep now,” exclaimed the learned Barrel Brow, “after all these centuries, when I think of the cruel fate that overtook my people. In a few months the whole face of our fair land was covered with ice and snow, and our cattle died, and many of our people, too, before they could weave thick cloth to keep their delicate bodies from the pinching cold. But this was not all; the great blue ocean which had until then dashed its warm waves and white foam up against our shores now breathed its icy breath full upon us, driving into our cellars to escape its fury; and in a few brief months, to our horror, there came drifting down upon us fields and mountains of ice, which the tempestuous waters cast up against our shores with deafening crash. To remain there meant death, swift and terrible, so the command was given to abandon homes and firesides and escape to the southward, and this most of them did. But it so happened that several hundred families belonging to the metal-working guilds, who knew the underground passages to the mines as foresters know the pathless wood, had taken refuge in the vast underground caverns with all the goods they could carry. Poor deluded creatures! they thought that this sudden coming of the winter blast, of the blinding snow and vast floating fields of ice, was but a freak of nature, and that in a few months the old warmth and the old sunshine would come back again.

“Alas, months went by and their supply of food was almost exhausted and the entrances to the mines were closed by gigantic blocks of ice cemented into one great mass by the snow which the gray clouds had sifted down upon them. There was now no escape that way. Their only hope was to make their way underground to some portal to the upper world.

“So, with lighted torches but with hearts plunged in the darkness of despair, they kept on their way, when one day, or one night, they knew not which, their leaders suddenly came upon a broad street of marble opened by nature’s own hands. It was skirted by a softly flowing river that swarmed with fish in scales and shells and skin, and here our people halted to eat and drink and rest, and while one of their number was striking his flint on one occasion to make a fire to cook a meal, to his surprise and delight a tongue of flame darted up from the rocky floor and continued to burn, giving light and warmth to them.

“As they had brought their tools—their drills and chisels and files and gravers and blow-pipes—with them in their carts and wagons, they made haste to fit a pipe to this opening in the rock and set up a cluster of lights. With food and water and warmth and light their hearts grew lighter, especially as they soon discovered that in many of the vast caverns gigantic mushrooms grew in the wildest profusion.

“The wisest of them,” continued the learned Barrel Brow, “at once made up their minds that there must be reservoirs of this gas farther along on this beautiful Marble Highway, so, day by day, they pushed farther into this World within a World, halting every now and then to set up a lighthouse as they called it.

“After advancing several leagues the exploring party, upon lighting a cluster of gas jets, were stricken almost speechless with wonder at finding themselves upon the very sill of a towering portal opening into a succession of vast chambers, some with flat ceiling, some arched, some domed, upon the floors and walls of which lay and hung inexhaustible quantities of pure silver. Those magnificent caverns were in reality nature’s vast storehouses of the glorious white metal, and our people made haste to set up clusters of gas jets here and there, so that they might view the wondrous treasure-house.

“Here they determined to remain, for here was food and water in never-failing supplies, and here they would have light and warmth, and here they could forget their miseries by working at their calling, using the precious metal with lavish hand to build them living-chambers, and to fashion the thousand and one things necessary for every-day life. So great was their delight as metal-workers to come upon this exhaustless supply of pure silver that they could hardly sleep until they had set up clusters of gas jets throughout these vast caverns, for, no doubt, little baron, thou hast already guessed that this is the spot I am telling thee of; that right here it was where our people halted to build the City of Silver.
