Leo made a wry face.

"Ah! you are not cosmopolitan."

"What is that?"

"A citizen of the world, a person free from national prejudices. Ah, these words are long for you; I will try to be simple: you have not learned to eat everything that is good."

"But rats are not good; they are vermin."

"Bah! yes, because you let them feed like your hogs on anything. We do better; we pen them, and give them grain until they are fat and sweet, and make them eatable."

Leo could not disguise his dislike, so Knops, shrugging his shoulders, did not attempt any longer to convince him, but said,

"Are you interested in what I have shown you?"

"Certainly I am," said Leo, with more spirit than he had ever put into words.

"And you care to go on?"

"Very much."

"Prepare then for great exertion. As you are so large it will be necessary for you to creep through many pa.s.sages. I am going to take you to see our water-work. The visit may be tiresome, but I think you will be repaid. It is generally supposed that giants have greater power than we. It may be that it is true, but I think it is doubtful. But you may wonder why I speak now of giants. It is because they have originated the opinion among men that the great water-falls and cataracts, such as those of the Nile and Niagara, are entirely of their producing, but we all know the familiar adage, 'Great oaks from little acorns grow.' I am going to show you where the little springs and rivulets have their rise."

Leo's attention had flagged during this speech--he was so unaccustomed to many words--now his interest revived.

"Do you remember a certain shady spot about half a mile from the monastery, beneath a group of birch-trees, and overhung with alders?"

asked Knops.

"Do I not, indeed?" responded Leo, eagerly. "It is the sweetest, coolest water on the estate. The moss around that spring is just like green velvet. Many a time I have plunged my whole head in it. The birds know it too, and always come there to drink. I sometimes find four or five of them dipping in at once; it is a pretty sight to see them bathe; they throw the water up under their wings until they drip, and then they are hardly satisfied."

"Well," said Knops, "we have the supplying of that spring."

All the time they had been talking, Knops had been leading the way through long pa.s.sages and down steep steps, of which Leo's long legs had to compa.s.s several at a stride.

Now they came to a low tunnel through which Leo had to creep for what seemed to him miles. Strange to say, the weariness which so often compelled him to rest or doze seemed to be leaving him. He felt an altogether new impulse, a desire to explore these recesses, and a great respect for Knops's learning also made him desirous of conversation, which was something he had always avoided by answering questions in the shortest possible way.

The tunnel was not only long and low, but it was dripping with moisture, and the air oppressive with what seemed to be steam. Leo heard wheezing and groaning sounds, which, though not frightful, were very peculiar, and then the thump-thump, as of engines.

Very glad was he when the tunnel opened into another large cavern, at the bottom of which was a lake. He could not have seen this had it not been for the electric fluid which blazed like daylight from a great globe overhead. On the margin of the lake were all kinds of hydraulic machines, small as toys, but of every conceivable form; derricks and wheels and screws and pumps, and all under the management of busy little elves, who panted and puffed and tugged at ropes and wheels and pipes as they worked, and kept up a constant chant not unlike the song of the wind on a stormy night.

Leo watched them intently. Once in a while one restless little sprite would turn a hose upon his companions, when the chant would stop long enough for the rest to dip him head and heels into the lake, which had a very quieting effect. Leo noticed great numbers of pipes running up the sides of the cavern in all directions, but Knops soon opened the door of what he called "the model-room," and here were new wonders displayed.

CHAPTER VI

The model-room of the elves' water-work department was a grotto of salt--glittering, dazzling, sparkling, and flashing--divided into two equal parts, or as if a huge shelf had been placed across it.

On the top of the shelf was a tiny park or forest, with all the natural differences of the ground exactly represented by gra.s.ses, plants, flowers, rocks, and trees, living and growing, but on a scale so small that Leo was forced to use a microscope to properly enjoy its beauty.

Even the herbage was minute, and the trees no larger than small ferns, but as his eyes grew accustomed to the gla.s.s he was amazed to find the hills and dales of his home here reproduced in the most familiar manner.

It was truly an exquisite scene. Field upon field dotted with daisies, woodland as dense and wild as untrained nature leaves it, and hill upon hill clambering over one another, all so minute and yet so real, and dashing down from the tiny mountains was a stream of foaming water, winding about and gathering in from all sides other tributary brooks, so small that they would hardly have floated a good-sized leaf.

And now Leo understood the meaning of it all, as he looked underneath the shelf where tiny pumps and rams were forcing up the water for this stream.

Knops touched a spring and set a new series of wheels in motion, when, instantly, a gushing fountain flowed up in a small stone basin beneath a rustic cross; then a little lake appeared, on which were sailing small swans; and finally a rushing, roaring flood started some mill-wheels and almost threatened destruction to the tiny buildings upon its banks.

"This," said Knops, "shows you how we use the power of our reservoirs, but it can give you no idea of the immense trouble we have in laying pipes for great distances. Some of our elves find it so difficult that they beg for other work, and many run off altogether and live above-ground, inhabiting the regions of springs and brooks, and so muddying them and filling them up with weeds that men let them alone, which is just what they desire."

"Do fish ever clog your pipes?" asked Leo.

"Never. We have none in our lakes; the water is too pure and free from vegetable matter for fish. It is doubly distilled. Taste it."

Leo took the gla.s.s which Knops offered, and confessed he had never tasted anything more delicious.

"We sometimes force carbonic gas into mineral springs, but that, as well as the salts considered so beneficial, is left to our chemists to regulate. Paz, do you know anything about this?"

"Not much, Master Knops. I have seen iron in various forms introduced, but think that is usually controlled by the earth's formation."

Leo sighed at his own ignorance, and vowed to study up these matters; but Knops, seeing his look of dejection, asked, "How would you like a bath?"

"Delightful. Where? Surely not in the lake; it looks so cold and gla.s.sy I should not dare."

"Oh, no, no," laughed Knops. "Do you think I'd let you bathe in a reservoir? Never! We are too cleanly for that, begging your pardon. Here is our general bath. It's quite a tub, isn't it?"

"I should think so," said Leo, surveying quite a s.p.a.cious apartment, about which were pipes and faucets, clothes-lines and screens.

Here his friend left him, and he was glad to doff his garments for a plunge. He found that he could make the water hot or cold at will, and so luxurious was it that he would have stayed in any length of time had not a crowd of elves come chattering in, and with whoop and scream surrounded him. Though they could not see him, they were conscious of some disturbing force in the water, and in an instant a lot of them had scrambled on his back, and were making a boat of him. They pulled his hair and his ears unmercifully, and because he swam slowly, with their weight upon him, they whacked and thumped him like little pirates. But he had his revenge, for with one turn he tumbled them all off, and sprang from the bath, leaving them to squirm and squabble by themselves.

Laughing heartily at their antics, he rejoined Knops and Paz, whom he found poring over some maps spread out before them.

"We have been discussing the length of a journey to the Geysers of Iceland, also to the hot springs of the Yellowstone, but I am afraid either would require too much time. Was your bath agreeable?"

"Very," said Leo, describing how he had been pummelled.

"Those were the fellows from the steam-rooms--stokers probably. Rough enough they are. Do you care to have a glance at them at work?"

"Don't care if I do," said Leo, in his old drawling manner; then, correcting himself, he added: "If it suits your convenience, I shall be very happy to take a look."

"That is all it will be, I promise you," said Paz; "the heat is awful."

Leo thought as much when Knops, having tied a respirator over his mouth, opened another door. Such a cloud of vapor puffed out that he could but dimly discern what seemed to be a tank of boiling, bubbling water, resting on a bed of soft coal, about which stark little forms were dancing and poking with long steel bars until flames leaped out like tongues of fire.

"Oh," said Leo, as he quickly turned from his place, "how do they endure it? It is dreadful!"

"They are used to it; they all came from Terra del Fuego," replied Knops, calmly. "And now, as a contrast to them, look in here."
